Electric bacteria join cells end to end to build electrical cables able to carry current up to 5 centimetres through mud. The adaptation, never seen before in a microbe, allows these so-called cable bacteria to overcome a major challenge facing many organisms that live in mud: a lack of oxygen. Its absence would normally keep bacteria from metabolizing compounds, such as hydrogen sulfide, as food. But the cables, by linking the microbes to sediments richer in oxygen, allow them to carry out the reaction long distance…
The more researchers have looked for “electrified” mud, the more they have found it, in both saltwater and fresh. They have also identified a second kind of mud-loving electric microbe: nanowire bacteria, individual cells that grow protein structures capable of moving electrons over shorter distances. These nanowire microbes live seemingly everywhere—including in the human mouth… Scientists are pursuing practical applications, exploring the potential of cable and nanowire bacteria to battle pollution and power electronic devices…
The Center for Electromicrobiology was established in 2017 by the Danish government. Among the challenges the center is tackling is mass producing the microbes in culture…Cultured bacteria would also make it easier to isolate the cable’s wires and test potential applications for bioremediation and biotechnology…
Electrical bacteria are everywhere. In 2014, for example, scientists found cable bacteria in three very different habitats in the North Sea: an intertidal salt marsh, a seafloor basin where oxygen levels drop to near zero at some times of the year, and a submerged mud plain just off the coast…Elsewhere, researchers have found DNA evidence of cable bacteria in deep, oxygen-poor ocean basins, hydrothermal vent areas, and cold seeps, as well as mangrove and tidal flats in both temperate and subtropical regions.
Nanowire bacteria are even more broadly distributed. Researchers have found them in soils, rice paddies, the deep subsurface, and even sewage treatment plants, as well as freshwater and marine sediments. They may exist wherever biofilms form, and the ubiquity of biofilms provides further evidence of the big role these bacteria may play in nature.
The microbes also alter the properties of mud, says Sairah Malkin, an ecologist at the University of Maryland Center for Environmental Science. “They are particularly efficient … ecosystem engineers.” Cable bacteria “grow like wildfire,” she says; on intertidal oyster reefs, she has found, a single cubic centimeter of mud can contain 2859 meters of cables, which cements particles in place, possibly making sediment more stable for marine organisms.

Oil pollution in Syria has been a growing concern since the 2011 onset of a civil war that has taken a toll on oil infrastructure and seen rival powers compete over control of key hydrocarbon fields. In the Kurdish-held northeast, a large storage facility in the Rmeilan oil field in Hasakeh province is of particular concern, according to the Dutch peace organisation PAX. [A River of Death, pdf] Oil leaks from the Gir Zero storage facility have been suspected since at least 2014, the latest in March 2020, it said in a June report. Thousands of barrels have leaked out into creeks in the area over the past five years, threatening the health and livelihoods of people in dozens of villages….
The major Rmeilan field controlled by the Kurdish administration, located near a US airbase, has been among the Syrian Kurds’ most prized assets since regime forces withdrew early on in the war. But oil wealth comes at a heavy cost for livestock farmers whose sheep and cows have died because they drank oil contaminated water.
Residents too suffer heavily from the pollution because of the foul odour of gas and crude oil wafting over the area… Compounding the situation, makeshift oil refineries have cropped up across the northeast in recent years, dumping oil waste in the waterways…These informal refineries receive oil from nearby fields and process it to provide benzine, gasoline and diesel to locals.

Regulators are weighing whether a local uranium company can import the material for processing at a mill near the border of a Native American reservation. For Energy Fuels Inc , the shipment represents an economic lifeline, after the company posted an operating loss of $7.8 million for the first quarter of 2020. Its president in March 2020 described the U.S. uranium industry as being “on the cusp of complete collapse.” But for the Ute Mountain Ute Tribe living near the facility – the only operational uranium mill in the United States – the proposal has stoked fears that tribal land will become a dumping ground for global radioactive waste. Both the White Mesa mill and the tribal reservation are in San Juan County, Utah’s poorest.
The mill, built in 1979, was only meant to process conventional uranium ores from the Colorado Plateau for up to 20 years, the tribe says. The Navajo Utah Commission and Navajo Nation have also that the company’s application be rejected. “The state of Utah must recognize and acknowledge the reality that the mill is far past its design life and no longer a conventional uranium mill, but, instead, a radioactive waste dump seeking to operate for decades, if not a millennium,” the Ute Mountain Ute Tribe said in a document submitted to the state….
The 660 tons of powdered material in question, now sitting in 2,000 drums at a plant on the Estonian coast near the Russian border, would be Energy Fuels’ first-ever radioactive import from outside North America. The powder is a byproduct from tantalum and niobium mining by Estonian company Silmet, which contains uranium. But it cannot stay within Estonia, where there is no licensed facility for reprocessing radioactive material. Energy Fuels says there is enough uranium in that byproduct that it is worth processing. Opponents say Energy Fuels is simply taking in waste, which would be stored on site. According to Energy Fuels business from the shipment would help the company keep its 70 workers employed.
Energy Fuels anticipates demand for domestic uranium could rise, after the Trump administration in April 2020 proposed a $1.5 billion federal uranium reserve that would purchase uranium from domestic producers. Such a reserve, however, would need Congressional approval – a major hurdle. The reserve was one of the main proposals to come from a federal Nuclear Fuel Working Group aimed at reviving the U.S. uranium and nuclear industry. The United States currently imports over 90% of its uranium from abroad for its reactors.

The annual inflow of plastic could nearly triple from 2016 to 2040, the study found, and even if companies and governments meet all their commitments to tackle plastic waste, it would reduce the projection for 2040 by only 7%, still a more-than twofold increase in volume. The study’s authors, the nonprofit Pew Charitable Trust and sustainability consulting firm Systemiq Ltd., set out a range of measures to stem the flow and called on businesses and governments to do more to reduce the use of plastic.
The study attributes the surge to a growing global population using more plastic per person. Other factors include greater use of nonrecyclable plastics and an increasing share of consumption occurring in countries with poor waste management. China and Indonesia are likely the top sources of plastic reaching the oceans, accounting for more than a third of the plastic bottles, bags and other detritus washed out to sea, according to a study published in 2015 by Jenna Jambeck, an environmental engineer at the University of Georgia.
Over the past two years China has been making strides to improve waste management, including banning the import of plastic and other waste from developed countries like the U.S., which for decades have shipped much of their trash overseas. Indonesia has implemented its own restrictions on trash coming in from overseas, while lawmakers in the U.S. are increasingly trying to find ways to improve the country’s domestic recycling rates as export markets vanish.
They found that flexible plastic packaging—particularly items like potato-chip bags and food pouches, which are made of several materials and typically aren’t recycled—accounts for a disproportionate amount of ocean plastic. The As You Sow report said companies should stop selling products in flexible plastic until it is recycled or composted in significant amounts. Companies, in response, have been redesigning flexible packaging to promote recycling. For example, Nestle recently began selling a line of Gerber baby-food pouches made from a single material. But hurdles remain, particularly around collection and sorting of the packaging…
The amount of plastic flowing into the oceans could be reduced by as much as 80% over the next 20 years through a combination of reduced plastic use, increased recycling, alternatives to problematic packaging like plastic pouches and better waste management, the Pew-Systemiq study said…

In the aftermath of the Fukushima Daiichi nuclear disaster, [UN Special Rapporteurs have] consistently raised concerns about the approaches taken by the government of Japan. UN Special Rapporteurs have been concerned that raising of “acceptable limits” of radiation exposure to urge resettlement violated the government’s human rights obligations to children.
UN Special Rapporteurs have been concerned of the possible exploitation of migrants and the poor for radioactive decontamination work. Their most recent concern is how the government used the COVID-19 crisis to dramatically accelerate its timeline for deciding whether to dump radioactive wastewater accumulating at Fukushima Daiichi in the ocean
The communities of Fukushima, so devastated by the tragic events of March 11, 2011, have expressed their concerns and opposition to the discharge of the contaminated water into their environment. It is their human right to an environment that allows for living a life in dignity, to enjoy their culture, and to not be exposed deliberately to additional radioactive contamination. Those rights should be fully respected and not be disregarded by the government in Tokyo. The discharge of nuclear waste to the ocean could damage Japan’s international relations. Neighboring countries are already concerned about the release of large volumes of radioactive tritium and other contaminants in the wastewater.
Japan has a duty under international law to prevent transboundary environmental harm. More specifically, under the London Convention, Japan has an obligation to take precaution with the respect to the dumping of waste in the ocean.
Indigenous peoples have an internationally recognized right to free, prior and informed consent. This includes the disposal of waste in their waters and actions that may contaminate their food. No matter how small the Japanese government believes this contamination will be of their water and food, there is an unquestionable obligation to consult with potentially affected indigenous peoples that it has not met…The disaster of 2011 cannot be undone. However, Japan still has an opportunity to minimize the damage…There are grave risks to the livelihoods of fishermen in Japan and also to its international reputation. Again, I urge the Japanese government to think twice about its legacy: as a true champion of human rights and the environment, or not.

Since March 2020, record amounts of gold dug from artisanal mines in the conflict zones of Eastern Congo have been smuggled across the porous border with Uganda, where it is being stamped with fake certifications before being shipped to international markets in Dubai, Mumbai and Antwerp, according to Ugandan security officials, smugglers and traders. Much of the gold is reaching these overseas markets using cargo planes returning from Uganda after delivering Covid-19 aid and other essential supplies, according to plane manifests seen by The Wall Street Journal.
The trade in conflict gold isn’t new, but it has perhaps never been more lucrative: Gold prices at illegal and unregulated Congolese mines, where supply chains have been disrupted by coronavirus shutdowns and renewed violence between militant groups, have dropped over 40% since April 2020, according to local traders, while on global markets, prices are up by almost a third…Activists and U.N. investigators have long accused Uganda and several of Congo’s neighbors of being complicit in the plunder of Congolese gold…The calls to end the illicit trade grew louder last year after Uganda’s gold exports overtook coffee to become the leading export commodity for the first time—despite the country producing very little bullion.
U.N. investigators estimate that each month between 2 tons and 3 tons of Congo’s conflict gold—with a market value of over $100 million—is crossing the Ugandan frontier, passing border crossings patrolled by heavily armed guards, with metal fencing and razor wire erected to reduce the flow of people due to coronavirus fears…
Smugglers and police say the gold is secreted in trucks that are allowed to bypass coronavirus restrictions to deliver “essential goods” from fuel to food supplies. The yellow bars, weighing between 5 to 20 kilograms, are stuffed underneath truck cabins, inside battery compartments and emptied gasoline tankers. Once inside Uganda, the truckers sell the bars to traders who purchase forged documents in Kampala that disguise the gold’s origin.
The scramble is fueling violence in the eastern Congolese province of Ituri…Fresh spasms of violence have left more than 1,300 civilians dead since March 2020, in what the U.N. says may amount to war crimes. Some six million people are displaced. Armed groups are carrying out predatory raids on mines in search of gold.
In the meantime on Wall Street, on July 24, 2020, gold futures were priced at $1,897.50 a troy ounce eclipsing their August 2011 peak of $1,891.90. The coronavirus has ignited a global gold rush, with physical traders around the world trying to get their hands on more metal and individuals around the world ordering bars and coins.

Scientists measured microplastics — tiny particles and fibers of plastic that can float in the air like dust — and found that over 1,000 tons a year are falling into wilderness areas and national parks in the western U.S. Janice Brahney of Utah State University and her team identified samples of microplastics and other particulates collected over 14 months in 11 national parks and wilderness areas to create the study published in the journal Science, on June 12, 2020. Pieces of plastic less than 5 mm in length, or microplastics, occur in the environment as a consequence of plastic pollution…
The presence of microplastics in oceans and water supplies has been a matter of concern for some time, but the impact of airborne microplastics is a relatively new area of study. Though microplastics are found nearly everywhere on Earth, the sources and processes behind their ubiquitous distribution, or the “global plastic cycle,” remain vaguely understood. Initially overlooked, recent studies have suggested that long-range atmospheric transport plays an important role in carrying microplastic pollution vast distances and to remote locations…
Examination of weekly wet and monthly dry samples from 11 sites allowed the authors to estimate that more than 1,000 tons of microplastics are deposited onto protected lands in the western U.S. each year, equivalent to more than 123 million plastic water bottles.
The ubiquity of microplastics in the atmosphere has unknown consequences for humans and animals, but the research team observed sizes of particles that were within the ranges that accumulate in lung tissue. Moreover, the accumulation of plastic in the wilderness areas and national parks could well influence the ecosystems in complicated ways.

The Runit Dome is a containment structure on Runit Island, located on Enewetak Atoll. Enewetak Atoll is a former U.S. atmospheric nuclear weapons test site located approximately 2,300 miles west of Hawaii in the northwest Pacific Ocean. The Runit Dome, which was built in the late 1970s, contains over 100,000 cubic yards of contaminated soil and debris [from the US nuclear weapons testing] that were encapsulated in concrete inside an unlined nuclear test crater, the Cactus Crater, on the north end of Runit Island. The site has remained a concern to the people of Enewetak.
The Runit Dome is not in any immediate danger of collapse or failure, and the exterior concrete covering the containment structure is still serving its intended purpose, effectively reducing the natural erosion of the waste pile below by wind and water. Visual surveys of the exterior concrete of the Cactus Crater containment structure have revealed the presence of cracks and spalls in the concrete cap. However, these cracks and spalls in the exterior concrete cap do not form sites for external or internal radiation exposure that impact or endanger human health or the environment, or wildlife.
DOE has performed preventative maintenance on exterior surfaces of the containment structure, which will aid in the determination of any changes that may occur in the condition of the concrete in the future. Any concerns about the imminent failure or collapse of the structure are unfounded.
The main safety concern to humans associated with leakage of radioactive waste from the Cactus Crater containment structure is the uptake of fallout radioactivity in marine foods. There are no data to suggest that the Cactus Crater containment structure, or more specifically, the radioactive material encapsulated in Cactus Crater, is currently having a measurable adverse effect on the surrounding environment or on the health of the people of Enewetak. However, DOE is in the process of establishing a groundwater radiochemical analysis program that is designed to provide scientifically substantiated data that can be used to determine what, if any, effects the dome contents are having, or will have, on the surrounding environment now and in the future.
Long-term trends in the concentration of Pu in lagoon waters derived from retrospective analysis of a coral core collected off Runit Island show levels of Pu in lagoon waters are systematically decreasing. These data provide compelling evidence that the construction of the Runit Dome has had, and continues to have, a negligible impact on the wider marine environment….
The Cactus Crater containment structure remains vulnerable to wave driven over wash and flooding caused by storm surge and potential effects of sea level rise… It is anticipated that any measured or modeled effects of storm events may help provide a better understanding of the long-term consequences of sea-level rise on mass-transport of dome derived radionuclides.
The UN Environment Programme in 2011 proposed the creation of a $1 billion fund to repair the damage done by decades of crude spills in the Ogoniland area in southeastern Nigeria. However, progress has been poor and the little work that has been done is sub-standard, advocacy groups including Amnesty International reported in June 2020. “Research reveals that there is still no clean-up, no fulfillment of ‘emergency’ measures, no transparency and no accountability for the failed efforts, neither by the oil companies nor by the Nigerian government,” the groups said.
Shell’s Nigerian unit pumped oil in Ogoniland until 1993, when the company withdrew amid increasing protests against its presence. Even though the Hague-based company no longer produces crude in the area, a joint venture operated by Shell Petroleum Development Company, or SPDC, still owns pipelines that crisscross the region.
A government agency responsible for overseeing the clean-up, the Hydrocarbon Pollution Remediation Project, known as Hyprep, was finally set up in 2017 after several false starts, but it’s failing to deliver. …“Hyprep is not designed, nor structured, to implement a project as complex and sizable as the Ogoniland clean-up,” the report cites UNEP as saying in 2019

The East African Court of Justice delivered in June 2020 a temporary injunction order to the country’s Minister for Justice, the Greater Pioneer Operating Company (GPOC), and the Dar Petroleum Operating Company. The Court approved the application by Hope for Humanity Africa (H4HA), a non-governmental organization (NGO), which sought to highlight the environmental damage caused by oil spills… The NGO contends that: “Over 47,249 of the local population in Upper Nile State and 60,000 in Unity State are at risk of being exposed to the oil pollution this is because the local population depends on the wild foods for survival, the contaminated swamps, streams and rivers waters for cooking, drinking, washing, bathing and fishing.”…
The H4HA is looking for an injunction to stop multiple companies from exporting oil from the region, including CNPC of China, Petronas of Malaysia, and Oil & Natural Gas Corp. of India (ONGC)
Global waste is expected to hit 3.4 billion tons by 2050 from 2.01 billion tons in 2016, according to the World Bank. As recycling programs encounter challenges and landfills in the U.S. and Europe reach capacity or face regulations making them more expensive, incinerators are becoming the most viable option for many municipalities to deal with much of their garbage. England now burns more municipal waste than it recycles or landfills. China—already the world’s biggest trash burner—is building more incinerators. And incineration companies say, for the first time in years, expansion projects are on the table in the U.S., although the industry faces significant legal and community challenges. Overall, incinerator-plant capacity is forecast to rise 43% globally between 2018 and 2028, according to Ecoprog, a consulting firm…..
Another growth driver is a European Union target for member states to cap the amount of municipal trash they send to landfill at 10% by 2030. Local communities and environmental groups have launched strong opposition to expansion of incineration plans, citing environmental and public-health concerns. Incinerator plants are also called waste-to-energy plants since the heat from burning trash is used to generate electricity, and many governments classify that electricity as renewable energy, a characterization opponents dispute…..But advocates for clean energy…say that while some energy is recovered by burning, recycling or composting garbage would save far greater amounts of energy.
Critics also say cities that own their incinerator plants have little incentive to pursue waste-reduction efforts because the plants are designed to run at full capacity. “Many countries are over-investing in incineration to cut down on landfilling, which will eventually lock them into burning,” said Janek Vähk, development and policy coordinator for Zero Waste Europe.
Excerpts from Saabira Chaudhuri, Trash Burning Ignites as World’s Waste Swells, WSJ, June 10, 2020
On May 13, Japan’s Nuclear Regulation Authority announced that the nuclear fuel reprocessing plant in Rokkasho, Aomori Prefecture, had met new safety standards created after the March 11, 2011, earthquake and tsunami….The Rokkasho plant is a 3.8 million square meter facility designed to reprocess spent nuclear fuel from the nation’s nuclear reactors. Construction began in 1993. Once in operation, the plant’s maximum daily reprocessing capacity will be a cumulative total of 800 tons per year. During reprocessing, uranium and plutonium are extracted, and the Rokkasho plant is expected to generate up to eight tons of plutonium annually.
Both are then turned into a mixed uranium-plutonium oxide (MOX) fuel at a separate MOX fabrication plant, also located in Rokkasho, for use in commercial reactors. Construction on the MOX facility began in 2010 and it’s expected to be completed in 2022. Japan had originally envisioned MOX fuel powering between 16 and 18 of the nation’s 54 commercial reactors that were operating before 2011, in place of conventional uranium. But only four reactors are using it out of the current total of nine officially in operation. MOX fuel is more expensive than conventional uranium fuel, raising questions about how much reprocessed fuel the facilities would need, or want.
The Rokkasho reprocessing plant can store up to 3,000 tons of spent nuclear fuel from the nation’s power plants on-site. It’s nearly full however, with over 2,900 tons of high-level waste already waiting to be reprocessed.
Why has it taken until now for the Rokkasho plant to secure approval from the nuclear watchdog? Decades of technical problems and the new safety standards for nuclear power that went into effect after the 2011 triple meltdown at the power plant in Fukushima Prefecture have delayed Rokkasho’s completion date 24 times so far. It took six years for the plant to win approval under the post-3/11 safety standards…By the time of the NRA announcement on May 13, 2020, the price tag for work at the Rokkasho plant had reached nearly ¥14 trillion.
Japan is the only non-nuclear weapons state pursuing reprocessing. But as far back as the 1970s, as Japan was debating a nuclear reprocessing program, the United States became concerned about a plant producing plutonium that could be used for a nuclear weapons program. The issue was raised at a Feb. 1, 1977, meeting between U.S. Vice President Walter Mondale and Prime Minister Takeo Fukuda. “Reprocessing facilities which could produce weapons grade material are simply bomb factories,” noted a declassified U.S. State Department cable on the meeting. “We want to cooperate (with Japan) to keep the problem under control.”
The U.S. oppose the Rokkasho plant’s construction in 1993, following an agreement in 1988 between the two countries on nuclear cooperation. ..The U.S.-Japan nuclear agreement meant the U.S. would give advance consent for Japan to send spent nuclear fuel to the United Kingdom and France — states with nuclear weapons — for reprocessing until Rokkasho was running at full-scale.
Currently, Japan has nearly 45 tons of plutonium stockpiled, including 9 tons held by domestic utilities. Another 21.2 tons is in the United Kingdom and France is holding 15.5 tons under overseas reprocessing contracts.
Thus, Japan finds itself caught between promises to the international community to reduce its plutonium stockpile through reprocessing at Rokkasho, and questions about whether MOX is still an economically, and politically, viable resource — given the expenses involved and the availability of other fossil fuel and renewable energy resources.

Smaller plastic particles are especially dangerous, because they are easily ingested and can enter organs and body fluids of organisms and thus propagate up the food chain. The fact that these particles are also co-contaminated with various chemicals and other pollutants makes accurate assessments of the effects and toxicity of plastic pollution challenging. A group of scientists led by the IAEA has recently published a comprehensive review on the effects on fish of ‘virgin’ micro- and nano-plastics – tiny plastic particles such as resin pellets used in plastics manufacturing. The review, published in the journal Environmental Science and Technology in March 2020, revealed that in 32% of all studies assessed, such virgin plastic particles were indeed affecting biological functions in fish, such as their behavior and neurological functions, as well as their metabolism, intestinal permeability and intestinal microbiome diversity.
Plastic particles below 5 mm in length are called microplastics. The smaller ones, with a size equal to or less than 100 nm (1/10 000 mm) are called nanoplastics. They are so tiny that one cannot see them with naked eye or even with an ordinary optical microscope.
According to the UN Environment Programme, 8 million tonnes of plastic end up the world’s oceans every year, often carried there by rivers. If the trend continues, by 2050 our oceans could contain more plastic than fish Microplastic particles are accidentally consumed by marine organisms, which are then consumed by predator fish. Nanoplastic particles are even more toxic to living organisms as they are more likely to be absorbed through the walls of digestive tracts and thereby transported into the tissues and organs. Consequently, such plastic particles can interfere with various physiological processes, from neurotransmission to oxidative stress and immunity levels of freshwater and marine organisms.

Plastic bags may make a temporary comback in some places because of COVID-19. In a setback, albeit temporary, for efforts to combat plastic waste, many state and local governments have suspended plastic bag bans and are prohibiting the use of reusable bags to stem the spread of COVID-19. The plastics industry is pushing for such measures, causing environmentalists to cry foul. San Francisco, which has been at the forefront of single-use plastics restrictions, issued an order “not permitting customers to bring their own bags, mugs, or other reusable items from home” as a measure “to prevent unnecessary contact.” Maine is delaying enforcement of its plastic bag ban to Jan. 15, 2021, after originally planning to roll it out on April 22—Earth Day….
The plastics industry has been advocating for such measures. In recent weeks, Bag The Ban, an initiative sponsored by the American Recyclable Plastic Bag Alliance, has endorsed editorials in newspapers such as the Boston Herald and the New Hampshire Union Leader advocating use of plastic bags to protect grocery workers from COVID-19.
Writing to the US Department of Health and Human Services, the Plastics Industry Association made a similar point. “Single-use plastic products are the most sanitary choice when it comes to many applications.” The association cited research on reusable bags, including a 2011 study from Loma Linda University and the University of Arizona that tested bags from shoppers selected randomly at the grocery store and found bacteria such as E. coli on 8% of them. It also pointed to a 2012 outbreak of norovirus in Oregon linked to use of a reusable food bag and cited a 2019 study from Portugal that found bacteria in bags.

A common fixture in refrigerators, furniture and footwear, polyurethane plastic is pretty much always in high demand. Humans worldwide cycle through millions of tons of the durable substance each year, sending the bulk of what’s not recycled to garbage dumps, where it leaks toxic chemicals into the environment as it very slowly breaks down. At least one of Earth’s organisms sees the stuff as a boon: a bacterial strain called Pseudomonas sp.TDA1. This polyurethane-munching microbe seems to thrive in waste dump sites. Studying the Pseudomonas strain and the chemical strategies it deploys could someday help researchers put a small dent in the world’s plastic problem, which has cumulatively saddled the planet with more than 8 billion tons of slow-degrading synthetic material.
Pseudomonas sp. TDA1 is one of only a few microbes known to be tolerant to polyurethane plastic’s typically toxic properties. What’s more, the bacteria doesn’t just withstand the plastic’s harsh ingredients: it uses some of them as a food source… But while the bacterium can metabolize a subset of the chemicals in polyurethane plastic, it doesn’t seem able to break down these products completely. In-depth studies of Pseudomonas sp. TDA1 will reveal the genes crucial to these plastic-attacking abilities. Understanding how these genes and their products work could help scientists engineer synthetic approaches to tackling plastic in the future.

The Soviet Union used the waters east of Novaya Zemlya to dump reactors, spent nuclear fuel and solid radioactive waste from both the navy and the fleet of nuclear-powered civilian icebreakers. About 17,000 objects were dumped in the period from the late 1960s to the late 1980s. Most of the objects are metal containers with low- and medium level radioactive waste. The challenge today, though, are the reactors with high-level waste and spent uranium fuel, objects that will pose a serious threat to the marine environment for tens of thousands of years if nothing is done to secure them.
The reactors from the submarines K-11, K-19 and K-140, plus the entire submarine K-27 (in the Kara Sea) and spent uranium fuel from one of the old reactors of the Lenin-icebreaker have to be lifted and secured. Also, the submarine K-159 (in the Barents Sea) that sank north of Murmansk while being towed for decommissioning in 2003 have to be lifted from the seafloor, the experts conclude. A study report made for Rosatom and the European Commission has evaluated the costs of lifting all six objects, bringing them safely to a yard for decommissioning and securing the reactors for long-term storage. The estimated price-tag for all six will €278 millions, of which the K-159 is the most expensive with a cost of €57.5 millions. Unlike the submarines and reactors that are dumped in relatively shallow waters in the Kara Sea, the K-159 is at about 200 meters depth, and thus will be more difficult to lift.

Substantial amounts of raw materials will be required to build new low-carbon energy devices and infrastructure. Such materials include cobalt, copper, lithium, cadmium, and rare earth elements (REEs)—needed for technologies such as solar photovoltaics, batteries, electric vehicle (EV) motors, wind turbines, fuel cells, and nuclear reactors…A majority of the world’s cobalt is mined in the Democratic Republic of Congo (DRC), a country struggling to recover from years of armed conflict…Owing to a lack of preventative strategies and measures such as drilling with water and proper exhaust ventilation, many cobalt miners have extremely high levels of toxic metals in their body and are at risk of developing respiratory illness, heart disease, or cancer.
In addition, mining frequently results in severe environmental impacts and community dislocation. Moreover, metal production itself is energy intensive and difficult to decarbonize. Mining for copper,and mining for lithium has been criticized in Chile for depleting local groundwater resources across the Atacama Desert, destroying fragile ecosystems, and converting meadows and lagoons into salt flats. The extraction, crushing, refining, and processing of cadmium can pose risks such as groundwater or food contamination or worker exposure to hazardous chemicals. REE extraction in China has resulted threatens rural groundwater aquifers as well as rivers and streams.
Although large-scale mining is often economically efficient, it has limited employment potential, only set to worsen with the recent arrival of fully automated mines. Even where there is relative political stability and stricter regulatory regimes in place, there can still be serious environmental failures, as exemplified by the recent global rise in dam failures at settling ponds for mine tailings. The level of distrust of extractive industries has even led to countrywide moratoria on all new mining projects, such as in El Salvador and the Philippines.
Traditional labor-intensive mechanisms of mining that involve less mechanization are called artisanal and small-scale mining (ASM). Although ASM is not immune from poor governance or environmental harm, it provides livelihood potential for at least 40 million people worldwide…. It is also usually more strongly embedded in local and national economies than foreign-owned, large-scale mining, with a greater level of value retained and distributed within the country. Diversifying mineral supply chains to allow for greater coexistence of small- and large-scale operations is needed. Yet, efforts to incorporate artisanal miners into the formal economy have often resulted in a scarcity of permits awarded, exorbitant costs for miners to legalize their operations, and extremely lengthy and bureaucratic processes for registration….There needs to be a focus on policies that recognize ASM’s livelihood potential in areas of extreme poverty. The recent decision of the London Metals Exchange to have a policy of “nondiscrimination” toward ASM is a positive sign in this regard.
A great deal of attention has focused on fostering transparency and accountability of mineral mining by means of voluntary traceability or even “ethical minerals” schemes. International groups, including Amnesty International, the United Nations, and the Organisation for Economic Co-operation and Development, have all called on mining companies to ensure that supply chains are not sourced from mines that involve illegal labor and/or child labor.
Traceability schemes, however, may be impossible to fully enforce in practice and could, in the extreme, merely become an exercise in public relations rather than improved governance and outcomes for miners…. Paramount among these is an acknowledgment that traceability schemes offer a largely technical solution to profoundly political problems and that these political issues cannot be circumvented or ignored if meaningful solutions for workers are to be found. Traceability schemes ultimately will have value if the market and consumers trust their authenticity and there are few potential opportunities for leakage in the system…
Extended producer responsibility (EPR) is a framework that stipulates that producers are responsible for the entire lifespan of a product, including at the end of its usefulness. EPR would, in particular, shift responsibility for collecting the valuable resource streams and materials inside used electronics from users or waste managers to the companies that produce the devices. EPR holds producers responsible for their products at the end of their useful life and encourages durability, extended product lifetimes, and designs that are easy to reuse, repair, or recover materials from. A successful EPR program known as PV Cycle has been in place in Europe for photovoltaics for about a decade and has helped drive a new market in used photovoltaics that has seen 30,000 metric tons of material recycled.

Nuclear and other radioactive material is hardest to protect when it is transported from point A to point B — more than half of the incidents of theft of radioactive material reported to the IAEA between 1993 and 2019 occurred while it was in transport.
Around 20 million shipments of nuclear and other radioactive material are regularly transported within countries and across borders each year. These materials are used in industry, agriculture and medicine, as well as in education. Some of them are also radioactive sources that are no longer useful, known as disused sources.
The aim of nuclear security during transport is to ensure that the material is secured throughout and that it is not used for criminal or malicious purposes. While the level of security differs depending on the sensitivity of the material, the fundamental elements of secure transport include physical protection, administrative measures, training and protection of information about the transport routes and schedule. In some cases, escort personnel may also need to be armed…
“During conversion of our research reactor from high enriched to low enriched uranium fuel, we had to transport highly radioactive spent reactor fuel from the site to the airport to be sent back to the original manufacturer, and we had to transport the new low enriched uranium fuel from the airport to the facility,” said Yusuf A. Ahmed, Director of the Centre for Energy Research and Training in Nigeria, who was involved in the conversion project. “Although the transport time is only a few hours, there is a lot that can happen during that time, from simple traffic accidents to malicious interventions and sabotage of shipments.”
While only around 30 countries use nuclear power and therefore have significant amounts of nuclear materials to transport, almost all countries use radioactive sources.

A shipment of 14 containers with spent nuclear fuel from Andreeva Bay to Atomflot in Murmansk, Russia took place in December 2019 but it was paid by Norway. Unloading the 40-years old spent uranium fuel elements from the rundown storage tanks and repacking them to transport containers came with a price-tag of 5 million kroner (€500 000), while the shipment from Andreeva Bay to Murmansk will cost additional 2,5 million kroner (€250 000).
The December 2019 shipment was the fourth that year, but the first one paid by Norway. In Andreeva Bay, only 65 kilometers from the border to Norway, the Soviet navy packed away its lethal leftovers. Without too much thought for the costs of future clean up. In Norway, like in Russia, the demand for action came out of fears for possible radioactive leakages that could have potentially negative impact on the important fisheries in the Barents Sea. So far, isotopes contamination has only been discovered in the sediments in the near proximity off the shore and not further out in the bay.
Concerns of nuclear accidents and radioactive leakages are also why Norwegian authorities have granted hundres of millions kroner in aid to secure and clean up the site. After 25 years of cooperation to improve the situation in Andreeva Bay, the Norwegian experts argue that direct financing of practical work is the best way to gain an insight into how Russia deals with the clean up.
By the end of Soviet times, in the late 1980s, a total of 22,000 spent nuclear fuel elements, equal to about 100 reactor cores from submarines, had accumulated at the run-down storage facilities. In addition came thousands of cubic meters of solid radioactive waste stored outdoor in rusty containers and hundreds of cubic meters of liquid radioactive waste in tanks.
The two first decades of international cooperation concentrated on improving the infrastructure. Buildings were erected to cover three concrete tanks holding the spent nuclear fuel, both to keep out rain and snow, but also to make sure the removal- and repacking work could take place in safe conditions. The quay by the shore was rebuilt, a new special crane for lifting transport casks where put in place. Even a new on-purpose designed ship was built, paid by Italy.
In 2017, the first load of containers with spent nuclear fuel left Andreeva Bay towards Murmansk, from where it go by rail to Mayak, Russia’s reprocessing plant north of Chelyabinsk east of the Ural Mountains. So far in 2019, three shipments paid by Russia and one shipment paid by Norway have left Andreeva Bay. “25% of the original amount of spent nuclear fuel is now removed,” says Per-Einar Fiskebeck…
The remaining waste, tank 3A holds numerous rusty, partly destroyed steel pipes where concrete of poor quality was filled in the space between. Some of those fuel assemblies are stuck in the canisters, while some of the canisters are stuck in the cells. This is high level nuclear waste with radiation levels close to the uranium fuel comparable to the melted fuel rods inside the ill-fated Chernobyl reactor.
Another groundbreaking milestone in the clean up work took place earlier this fall when the retrieval of six abandoned, highly radioactive spent nuclear fuel assemblies from the bottom of Building No. 5 were successfully completed. Building No. 5 is a former pool storage, where several elements fell to the floor following a water-leakages in 1982. Traces of uranium and other radionuclides remained in the sludge at the bottom of the pool.

By the end of 2019, Japan further delayed the removal of thousands of spent fuel units that remain in cooling pools since the 2011 disaster The government and the plant operator, Tokyo Electric Power Co., are keeping a 30- to 40-year completion target.
More than 4,700 units of fuel rods remain at the three melted reactors and two others that survived the 2011 earthquake and tsunami. They pose a high risk because their storage pools are uncovered and a loss of water in case of another major disaster could cause the fuel rods to melt, releasing massive radiation. Their removal at Units 1 and 2, after repeated delays, is now postponed by up to 10 years from the initial target of 2018, with more preparation needed to reduce radiation and clear debris and other risks.
Fuel rod removal at the Unit 1 reactor pool will begin sometime in 2027-2028, after debris is cleaned up and a huge rooftop cover installed to contain radioactive dust. Fuel removal at Unit 2 pool is to begin in 2024-2026. Work at the Unit 3 reactor pool began in April 2019 and all 566 units will be removed by March 2021. TEPCO has emptied the pool at Unit 4, which was offline and only suffered building damage, and aims to have all remaining rods in reactor pools removed by 2031 for safer storage in dry casks.
TEPCO has been unable to release the 1.2 million tons of treated but still radioactive water kept in nearly 1,000 tanks at the plant, fearing public repercussions and the impact on the area’s struggling fishing and agriculture. The amount of water is growing by 170 tons daily because it is used to cool the melted fuel inside the reactors.
The Ministry of Economy, Trade and Industry recently drafted a proposal to release the water to the sea or the air, or a combination of both. TEPCO says it can only store up to 1.37 million tons, or until the summer of 2022. Time is limited because preparation is needed before any water release. TEPCO and the government say the tanks pose risks if they were to spill their contents in another major earthquake, tsunami or flood…. The water is still somewhat contaminated, but TEPCO says further treatment can remove all but radioactive tritium to levels allowed for release. Experts say tritium is not harmful to humans in small amounts and has been routinely released from nuclear plants around the world.
Removing an estimated 880 tons of molten fuel from Fukushima’s three melted reactors is the toughest and unprecedented challenge. It’s six times the amount dealt with in the aftermath of the 1979 Three Mile Island partial core melt in the United States. Removal is to begin in 2021 at Unit 2, where robotic probes have made more progress than at Units 1 and 3. A robotic arm was developed to enter the reactor from the side to reach the melted fuel, which has largely fallen to the bottom of the primary containment vessel… The first decade through 2031 is a crucial phase that will affect future progress…
Japan has yet to develop a plan to dispose of the highly radioactive melted fuel and other debris that come out of the reactors. TEPCO will compile a plan for those after the first decade of melted fuel removal. Managing the waste will require new technologies to reduce its volume and toxicity. TEPCO and the government say they plan to build a site to store waste and debris removed from the reactors, but finding one and obtaining public consent will be difficult.
Additionally, there will be an estimated 770,000 tons of solid radioactive waste by 2030, including contaminated debris and soil, sludge from water treatment, scrapped tanks and other waste. They will be sorted, treated and compacted for safe storage under a plan to be compiled by 2028.
The government says Fukushima’s decommissioning cost is estimated at 8 trillion yen ($73 billion), though adding compensation, decontamination of surrounding areas and medium-term storage facilities would bring the total to an estimated 22 trillion yen ($200 billion). The Japan Center for Economic Research, a think tank, estimates that decommissioning alone would cost 51 trillion yen ($470 billion) if the water is not released and tritium removal technology is pursued.
More than 10,000 workers will be needed annually in coming years, about one third assigned to work related to the radioactive water.

The federal agency overseeing oil and gas operations in the Gulf of Mexico after hurricane Katrina reported that more than 400 pipelines and 100 drilling platforms were damaged. The U.S. Coast Guard, the first responder for oil spills, received 540 separate reports of spills into Louisiana waters. Officials estimated that, taken together, those leaks released the same amount of oil that the highly publicized 1989 Exxon Valdez disaster spilled into Alaska’s Prince William Sound — about 10.8 million gallons…
While hurricanes gain speed due to the effects of climate change, the push for oil leasing in the Gulf of Mexico shows no sign of slowing down. In 2014, the Obama administration opened up 40 million new acres in the Gulf for oil and gas development. Four years later, the Trump administration announced plans to open up most of the rest, in what would be the largest expansion of offshore oil and gas drilling in U.S. history. Many of these 76 million acres are to be offered at reduced royalty rates to encourage additional near-shore drilling in Louisiana waters…
“In the Gulf, storms are predicted to be less frequent but more intense when they do come,” said Sunshine Van Bael, an ecologist at Tulane University who evaluated damage to marsh ecosystems from the BP oil spill. “One thing that storms do is, if oil has been buried underneath the marsh because it wasn’t rehabilitated, a storm could come along and whip that back up to the surface. So, the aftereffects of the oil spills might be greater [with climate change] since the storms are predicted to be more intense.”…
In 2009, a class-action lawsuit against Murphy Oil Corp. ended in a settlement requiring the company to pay $330 million to 6,200 claimants, including owners of about 1,800 homes in St. Bernard Parish. The damage occurred when one of Murphy’s storage tanks floated off its foundation during Katrina and dumped over a million gallons of crude oil into a square-mile segment of Meraux and Chalmette….
To date, more than $19 million has been paid out from the federal Oil Spill Liability Trust Fund to reimburse at least two oil companies for costs they incurred cleaning up oil they spilled during Katrina…
“We don’t normally penalize [companies] for act of God events,” Greg Langley of the Department of Environmental Quality said. “We just get right to remediation.”

E-waste is the fastest-growing element of the world’s domestic waste stream, according to a 2017 report by the UN’s Global E-waste Monitor. Some 50m metric tonnes will be produced annually in 2020 — about 7kg for every person in the world. Just 20 per cent will be collected and recycled. The rest is undocumented, meaning it likely ends up in landfill, incinerated, traded illegally or processed in a substandard way. That means hazardous substances spilling into the environment, poisoning the ground and people living nearby.
Heavy metals such as mercury, lead and cadmium — commonly found in LCD screens, refrigerators and air-conditioning units — as well as chemicals such as CFCs and flame retardants found in plastics can contaminate soil, pollute water and enter the food chain. Research last year by Basel Action Network, an NGO, linked toxic e-waste shipped from Europe to contaminated chicken eggs in Agbogbloshie — a Ghanaian scrapyard where 80,000 residents subsist by retrieving metals from electrical waste. Eating just one egg from a hen foraging in the scrapyard would exceed the European Food Safety Authority’s tolerable daily intake for chlorinated dioxins 220-fold.
Some appliances are more likely to be recycled than others. The recycling rate for big appliances, such as fridges and cookers, is about 80 per cent. That is because they are harder to dispose of and eventually get picked up, even when they are dumped by the kerb. Of small appliances, however, barely one in five makes it to the recycling centre. Across the world, governments are trying different ways to reduce e-waste and limit the amount that ends up in landfill.
For some time, EU countries have operated a one-for-one take-back system — which means that distributors need to take back, for free, an older version of any equipment they sell you. But since the rapid rise of online retailers, this has been harder to implement
In the end, all e-waste needs to be reduced to core metals. “It’s a bit like a mining activity.” In certain recycling plants robots have been programmed to dismantle flatscreen TVs, extracting precious metals such as cobalt or lithium, whose deposits are limited and increasingly valuable. “One of the hardest things about recycling is that you are not sure how [the manufacturers] made it.” Companies are encouraged to include this information on their devices. It could be a file with instructions readable by robots that could then proceed with the dismantling, making the process “easier, cheaper and more circular”. However, manufacturers have so far kept a close guard on the design of their products.
Many pressure groups and lawmakers have concluded that improving recycling rates will not be sufficient to tackle the global e-waste problem. Increasingly, they are advocating for the right to repair. In October 2019, the EU adopted a package of design measures to make household appliances more repairable. Starting from March 2021, manufacturers selling certain household appliances will have to ensure that spare parts are available for a number of years after their product has launched; that their items can be easily disassembled (and so use screws not glue); and that they provide access to technical information to repair professionals.
The rules cover appliances including refrigerators, washing machines, dishwashers and televisions. But they do not extend to IT equipment such as laptops, tablets and mobile phones. “The road to a new product is very easy, and the road to a successful repair very difficult,” says Martine Postma, founder and director of Repair Café International Foundation, which celebrated its 10th anniversary last year. Since its first repair event in Amsterdam in 2009, the organisation has grown to nearly 2,000 repair groups in 35 countries around the world. Now, it wants to collect more data about electronic gadgets, to see if it can plot “weak points” in design that could help manufacturers make them more repairable.
Excerpts from Aleksandra Wisniewska, What happens to your old laptop? The growing problem of e-waste, http://wiki.ban.org, Jan. 10, 2020
A salty substance called “brine,” is a naturally occurring waste product that gushes out of America’s oil-and-gas wells to the tune of nearly 1 trillion gallons a year, enough to flood Manhattan, almost shin-high, every single day. At most wells, far more brine is produced than oil or gas, as much as 10 times more. Brine collects in tanks, and workers pick it up and haul it off to treatment plants or injection wells, where it’s disposed of by being shot back into the earth…
The Earth’s crust is in fact peppered with radioactive elements that concentrate deep underground in oil-and-gas-bearing layers. This radioactivity is often pulled to the surface when oil and gas is extracted — carried largely in the brine…
Radium, typically the most abundant radionuclide in brine, is often measured in picocuries per liter of substance and is so dangerous it’s subject to tight restrictions even at hazardous-waste sites. The most common isotopes are radium-226 and radium-228, and the Nuclear Regulatory Commission requires industrial discharges to remain below 60 for each. Some brine samples registered combined radium levels above 3,500, and one was more than 8,500. “It’s ridiculous that those who haul brine are not being told what’s in their trucks,” says John Stolz, Duquesne’s environmental-center director. “And this stuff is on every corner — it is in neighborhoods. Truckers don’t know they’re being exposed to radioactive waste, nor are they being provided with protective clothing.
“Breathing in this stuff and ingesting it are the worst types of exposure,” Stolz continues. “You are irradiating your tissues from the inside out.” The radioactive particles fired off by radium can be blocked by the skin, but radium readily attaches to dust, making it easy to accidentally inhale or ingest. Once inside the body, its insidious effects accumulate with each exposure. It is known as a “bone seeker” because it can be incorporated into the skeleton and cause bone cancers called sarcomas. It also decays into a series of other radioactive elements, called “daughters.” The first one for radium-226 is radon, a radioactive gas and the second-leading cause of lung cancer in the U.S. Radon has also been linked to chronic lymphocytic leukemia.
Oil fields across the country — from the Bakken in North Dakota to the Permian in Texas — have been found to produce brine that is highly radioactive. “All oil-field workers,” says Fairlie, “are radiation workers.” But they don’t necessarily know it.
The advent of the fracking boom in the early 2000s expanded the danger, saddling the industry with an even larger tidal wave of waste to dispose of, and creating new exposure risks as drilling moved into people’s backyards. “In the old days, wells weren’t really close to population centers. Now, there is no separation,” says City University of New York public-health expert Elizabeth Geltman. In the eastern U.S. “we are seeing astronomically more wells going up,” she says, “and we can drill closer to populations because regulations allow it.” As of 2016, fracking accounted for more than two-thirds of all new U.S. wells, according to the Energy Information Administration. There are about 1 million active oil-and-gas wells, across 33 states, with some of the biggest growth happening in the most radioactive formation — the Marcellus. …
There is little public awareness of this enormous waste stream, the disposal of which could present dangers at every step — from being transported along America’s highways in unmarked trucks; handled by workers who are often misinformed and underprotected; leaked into waterways; and stored in dumps that are not equipped to contain the toxicity. Brine has even been used in commercial products sold at hardware stores and is spread on local roads as a de-icer…
But a set of recent legal cases argues a direct connection to occupational exposure can be made… Pipe cleaners, welders, roughnecks, roustabouts, derrickmen, and truck drivers hauling dirty pipes and sludge all were exposed to radioactivity without their knowledge and suffered a litany of lethal cancers. An analysis program developed by the Centers for Disease Control and Prevention determined with up to 99 percent certainty that the cancers came from exposure to radioactivity on the job, including inhaling dust and radioactivity accumulated on the workplace floor, known as “groundshine.”
“Almost all materials of interest and use to the petroleum industry contain measurable quantities of radionuclides,” states a never-publicly released 1982 report by the American Petroleum Institute, the industry’s principal trade group, passed to Rolling Stone by a former state regulator. Rolling Stone discovered a handful of other industry reports and articles that raised concerns about liability for workers’ health. A 1950 document from Shell Oil warned of a potential connection between radioactive substances and cancer of the “bone and bone marrow.” In a 1991 paper, scientists with Chevron said, “Issues such as risk to workers or the general public…must be addressed.”
“There is no one federal agency that specifically regulates the radioactivity brought to the surface by oil-and-gas development,” an EPA representative says. In fact, thanks to a single exemption the industry received from the EPA in 1980, the streams of waste generated at oil-and-gas wells — all of which could be radioactive and hazardous to humans — are not required to be handled as hazardous waste. In 1988, the EPA assessed the exemption — called the Bentsen and Bevill amendments, part of the Resource Conservation and Recovery Act — and claimed that “potential risk to human health and the environment were small,” even though the agency found concerning levels of lead, arsenic, barium, and uranium, and admitted that it did not assess many of the major potential risks. Instead, the report focused on the financial and regulatory burdens, determining that formally labeling the “billions of barrels of waste” as hazardous would “cause a severe economic impact on the industry.”…
There is a perception that because the radioactivity is naturally occurring it’s less harmful (the industry and regulators almost exclusively call oil-and-gas waste NORM — naturally occurring radioactive material, or TENORM for the “technologically enhanced” concentrations of radioactivity that accumulate in equipment like pipes and trucks.”…
In Pennsylvania, regulators revealed in 2012 that for at least six years one hauling company had been dumping brine into abandoned mine shafts. In 2014, Benedict Lupo, owner of a Youngstown, Ohio, company that hauled fracking waste, was sentenced to 28 months in prison for directing his employees to dump tens of thousands of gallons of brine into a storm drain that emptied into a creek that feeds into the Mahoning River. While large bodies of water like lakes and rivers can dilute radium, Penn State researchers have shown that in streams and creeks, radium can build up in sediment to levels that are hundreds of times more radioactive than the limit for topsoil at Superfund sites. Texas-based researcher Zac Hildenbrand has shown that brine also contains volatile organics such as the carcinogen benzene, heavy metals, and toxic levels of salt, while fracked brine contains a host of additional hazardous chemicals. “It is one of the most complex mixtures on the planet,” he says…
“There is nothing to remediate it with,” says Avner Vengosh, a Duke University geochemist. “The high radioactivity in the soil at some of these sites will stay forever.” Radium-226 has a half-life of 1,600 years. The level of uptake into agricultural crops grown in contaminated soil is unknown because it hasn’t been adequately studied.
“Not much research has been done on this,” says Bill Burgos, an environmental engineer at Penn State who co-authored a bombshell 2018 paper in Environmental Science & Technology that examined the health effects of applying oil-field brine to roads. Regulators defend the practice by pointing out that only brine from conventional wells is spread on roads, as opposed to fracked wells. But conventional-well brine can be every bit as radioactive, and Burgos’ paper found it contained not just radium, but cadmium, benzene, and arsenic, all known human carcinogens, along with lead, which can cause kidney and brain damage.
Ohio, because of its geology, favorable regulations, and nearness to drilling hot spots in the Marcellus, has become a preferred location for injection wells. Pennsylvania has about a dozen wells; West Virginia has just over 50. Ohio has 225. About 95 percent of brine was disposed of through injection as of 2014. Government scientists have increasingly linked the practice to earthquakes, and the public has become more and more suspicious of the sites. Still, the relentless waste stream means new permits are issued all the time, and the industry is also hauling brine to treatment plants that attempt to remove the toxic and radioactive elements so the liquid can be used to frack new wells.
Excerpts from America’s Radioactive Secret, Rolling Stone Magazine, Jan. 21, 2020
For decades, America and much of the developed world threw their used plastic bottles, soda cans and junk mail in one bin. The trash industry then shipped much of that thousands of miles to China, the world’s biggest consumer of scrap material, to be sorted and turned into new products. That changed last year when China banned imports of mixed paper and plastic and heavily restricted other scrap. Beijing said it wants to stimulate domestic garbage collection and end the flow of foreign trash it sees as an environmental and health hazard. Since then, India, Malaysia, Vietnam, Thailand and Indonesia—other popular markets for the West’s trash—have implemented their own restrictions…China’s 2018 restrictions on a variety of waste imports radically changed global flows of plastics, including polyethylene, a popular type used in shopping bags and shampoo bottles.
For years, the world’s bottles and boxes made their way to China on ships that offered deep discounts to avoid returning empty after dropping off cargo in the U.S. and other countries. Since 1992, China has imported 45% of the world’s plastic waste, according to data published in 2019 in the journal Science Advances. “It was a great relationship, where we bought their goods and sent them back the empty boxes,” says Brent Bell, vice president of recycling for Houston-based Waste Management, the largest waste management company in the U.S. In 2018, China instituted a ban on 24 categories of waste—including, for example, plastic clamshell containers, soda and shampoo bottles, and junk mail. It said foreign garbage was “provoking a public outcry.”
China accepted dirty and mixed recyclables because it had low-wage workers to sort out unwanted material, often by hand. That gave American contractors little incentive to weed out food scraps, plastic bags and nonrecyclable junk stateside. After China rejected imports, a flood of trash was rerouted to countries such as India, Indonesia and Malaysia. Many of those places now say they are overwhelmed and have imposed their own restrictions on paper or plastic imports. The countries also want to focus on developing their own waste collection industries.
Malaysia in May 2019 began sending back 60 containers of imported trash to the U.S. and other countries, complaining it had become a dumping ground for rich countries. The containers were meant to contain plastic scrap but were contaminated with other items such as cables and electronic waste. A government spokeswoman said more containers will be returned as Malaysia ramps up inspections.
Japan, which historically sent most of its plastic exports to China, had been redirecting trash to Malaysia, Thailand and Vietnam after China’s ban. But when those countries began turning dirty recycling away, Japanese collectors started stockpiling, in hopes a new market would arise. Over the past year, Japan has amassed 500,000 tons of plastic waste, according to Hiroaki Kaneko, deputy director of recycling at the environment ministry. Japan, the second-biggest exporter of plastic waste behind the U.S., is trying to stimulate domestic processing by earmarking billions of yen to subsidize plastic recycling machinery for private companies.
The U.K. is burning more of its trash, including dirty or low-value recycling. Attitudes toward incineration vary greatly by country. In the U.S., where space is plentiful, it has long been cheaper to send materials to landfills, and incineration has remained unpopular. Across much of Europe, by contrast, trash burned for energy has been popular for years. ….“The China ban has highlighted that we can no longer export our problem,” said managing director Bill Swan. Paper Round’s buyers have much higher standards now, he said, such as checking moisture levels, which can decrease the quality of paper.

An increase in the number of teens and young adults diagnosed with a rare cancer in the southwest corner of Pennsylvania has caused the state to look for a link between fracking and the disease.The investigation was sparked by a spate of Ewing’s sarcoma cases in and around Washington County, which has more Marcellus Shale gas wells than any other county in the state. In April 2019 state Department of Health found that the cases didn’t constitute a statistically significant cancer cluster. But affected families and other residents lobbied the governor for an investigation.
The region is home to coal mining, oil drilling, chemical plants and a former uranium-processing facility. Each year, about 250 children in the U.S. are diagnosed with Ewing’s sarcoma, a rare cancer of the bone or surrounding soft tissue, according to the National Institutes of Health. In four counties in southwest Pennsylvania, 31 people were diagnosed with Ewing’s sarcoma from 2006 through 2017, according to state cancer data. That is a roughly 40% increase from the period from 1995 through 2005, when 22 people in the same area were diagnosed, according to state data. Residents point to two additional cases in 2018. Most troubling to many local residents is that the six cases in Washington County since 2008 occurred in one school district.
Other communities are studying potential health risks of fracking. In October 2019, Colorado regulators said they would tighten regulation of drilling after a state-funded study found that people living within 2,000 feet of oil-and-gas wells could have, in worst-case scenarios, an elevated risk for infrequent, short-term health effects such as nosebleeds and headaches from emissions.
Evelyn Talbott, a professor of epidemiology at the University of Pittsburgh, said Pennsylvania investigators should look at residents’ potential exposures to chemicals and to radiation from natural-gas sites. She said they also should look at the sealed waste site of the defunct uranium-processing plant…Since Pennsylvania’s first Marcellus Shale well was drilled in Washington County in 2003, more than 1,800 wells have been fracked there. Compressor stations, processing plants and pipelines have followed. Some residents worry that pollutants such as benzene from air emissions or radium from wastewater could affect people’s health.
A global operation led by INTERPOL involving 61 countries and regional law enforcement partners has identified thousands of illicit activities behind severe marine pollution. Code-named 30 Days at Sea 2.0, the month-long (1-31 October, 2019) operation gathered more than 200 enforcement authorities worldwide for concerted action across all continents. Illustrating the severe global extent of marine pollution crime, preliminary operational results have already revealed more than 3,000 offences detected during 17,000 inspections. The offences – such as illegal discharges at sea, in rivers, or in coastal areas – were found to have been committed primarily to avoid the cost of compliance with environmental legislation.
The operation gathered more than 200 enforcement authorities worldwide, such as here in Bosnia and Herzegovina where officers inspect a company suspected of illegal discharge into local rivers In Nigeria, INTERPOL’s National Central Bureau in Abuja coordinated the action of 18 authorities through a task force created to conduct inspections into illegal oil refineries, found responsible for severe oil leakages polluting the country’s waterways. Information exchanged between Malaysia and The Netherlands permitted authorities to identify the source country of seven containers of plastic waste being illegally shipped into Malaysia from Belgium via Hong Kong, and to initiate their repatriation.
Marine pollution: thousands of serious offences exposed in global operation, Interpol Press Release, Dec. 16, 2019.
Less than half of the world’s larger miners have released safety and environmental details about their mine-waste dams, showing the mixed success of investors’ demands for greater transparency after the deadly Brumadinho dam collapse in Brazil. In January, 2019, 270 people died following the collapse of a tailings dam owned by Brazil’s Vale SA. The incident prompted a coalition of investors who manage more than $13 trillion to ask 726 companies in the mining and oil-sands business to disclose information on their dams. Nearly 55% of companies hadn’t delivered as of November 2019. While some of the largest miners—including Vale, BHP , and Anglo American have disclosed their information, others have yet to do so. Investors are increasingly examining ethical issues when looking at mining.
Tailings, the waste material from extracting valuable minerals, are often held for decades behind dams that can be risky if they are poorly constructed, ill-maintained or filled with too much waste. Major failures of tailings dams have become more frequent as mining companies ramp up production to meet the world’s growing demand for commodities. Norilsk Nickel one of world’s most valuable miners with a market capitalization of roughly $43 billion, hasn’t publicly released details on its tailings dams. In 2016, heavy rainfall caused a Norilsk Nickel tailings dam in northern Russia to overflow, coloring a local river red. Miners of potash and phosphate—minerals used mainly in fertilizers—have been slow to disclose.
Another big company that has not released details is Canada-based Nutrient. Satellite images show two of the company’s six Saskatchewan mines are located a few miles from residential communities and one neighbors a bird-breeding area. A tailings pond at the company’s North Carolina phosphate mine is located next to the Pamlico River, which feeds into the state’s largest estuary.
In 2017, Israel Chemicals reported that the partial collapse of a subsidiary’s dike in Israel released 100,000 cubic meters of acidic wastewater that flowed into a nearby nature reserve. The wastewater resulted from the production of phosphate fertilizer.Vancouver-based Imperial Metals Corp.is tied to what is considered one of Canada’s worst environmental catastrophes. In 2014, a British Columbia dam owned by the company burst, sending some 25 million cubic meters of mining waste pouring into a pair of glacial lakes
Large Chinese miners such as Jiangxi Copper, Zijin Mining Group Co. and Zhongjin Gold Corp. also haven’t shared information with the investor coalition. There are 8,869 documented tailings dams, of which 16% are within about half a mile of a residential area, school or hospital, according to research led by the School of University of Science and Technology in Beijing. Karen Hudson-Edwards, a mining specialist at Britain’s University of Exeter, said the actual number in China is estimated at around 12,000 dams and there is little transparency on tailings risk in the country. There have been at least 12 serious tailings-dam accidents in China since the 1960s, with one in 2008 killing 277 people, according to the World Information Service on Energy, a Netherlands-based nonprofit.

Russian environmental activists and residents are sounding the alarm (in December 2019) over government plans to build a motorway near a Soviet-era radioactive waste site in southeast Moscow that they fear could spew dangerous particles into the air. The 34-km (21-mile) road, which city authorities say is safe and will help ease traffic, is set to pass the Moscow Polymetal Plant and a fenced-off site where it disposed of radioactive substances decades ago. Vasily Desyatkov, a senior city construction official, said surface and underground tests carried out where the foundations of the road were due to be laid had turned back normal readings that show there is no risk.
But that has not placated activists who have led a series of protests in recent months. “It could lead to the release of radionuclides contained in the soil which will be dispersed with the dust. They will be spread everywhere – on people’s feet, car wheels, anything,” said Igor, a protester.
The site, the Moscow Polymetals Plant’s slag heap, is Just 13 kilometers from the Kremlin and steps from Kolomenskoye Park, a popular spot for Muscovites to ski in winter and picnic in summer, the Moskvorechye-Saburovo hill is the most contaminated of the bunch, according to Radon, a government agency tasked with locating and clearing radioactive waste. A legacy of a rushed Soviet effort to begin nuclear research as the race to build an atomic bomb gained steam in the 1930s, the hill is one of many contaminated sites across Russia …
It contains tens of thousands of tons of radioactive waste left over after the extraction of thorium and uranium from ore. The factory ceased production of metals in 1996 for “environmental reasons,” according to its website — it now produces weapons and military equipment — and the dump is now a hill half a kilometer wide sloping down to the banks of the Moscow River. City officials had been considering a full-scale clean-up for years, but never rubber-stamped a plan due to the risky location of the site near a source of water for Moscow’s southern suburbs.
“Operations in such an environment are a serious engineering challenge — one incautious step, and radioactive soil gets into the river,” said Alexander Barinov, Radon’s chief engineer for Moscow…. “Full decontamination by removing all of the radioactive waste is simply impossible,” he added, noting that Radon every year conducts “a kind of therapy” to ensure the site’s safety — in short, dumping dirt on top of the waste to keep it buried after topsoil runoff each spring.

The Triad National Security,*** the company in charge of Los Alamos National Laboratory’s (LANL) operations in 2018 lost track of 250 barrels of mixed hazardous waste on their way to the Waste Isolation Pilot Plant (WIPP) in Carlsbad. Mixed waste contains low-level radioactive waste and other hazardous materials. Failing to track such a high volume of waste is an egregious error that falls in line with the lab’s long history of serious missteps. “The fact that LANL has mischaracterized, misplaced, mis-inventoried — or whatever — 250 barrels of waste is pretty astounding,” said Jay Coghlan, executive director of Nuclear Watch New Mexico.
Still, Triad has committed less than a tenth of the violations that its predecessor, Los Alamos National Security LLC, used to average in a given year. A disastrous “kitty litter” incident happened under Los Alamos National Security, in which a waste barrel was packaged in error with a volatile blend of organic cat litter and nitrate salts, causing the container to burst and leak radiation at the Southern New Mexico storage site. WIPP closed for almost three years, and the cleanup cost about $2 billion.
***Triad is a public service oriented, national security science organization equally owned by its three founding members: Battelle Memorial Institute (Battelle), The Texas A&M University System (TAMUS), and The Regents of the University of California (UC).

Several members of the Tao Aboriginal community in Taiwan reiterated their decades-long demand that the government remove nuclear waste from Taitung County’s Orchid Island saying that they would not accept the NT$2.55 billion (US$83.57 million) in compensation. Since construction of a storage site was finished in 1982, more then 100,000 barrels of low-level radioactive waste have been transported from nuclear power plants on Taiwan proper to the outlying island, without obtaining residents’ consent in advance…. [According to the community], the government should establish a platform to discuss how to handle the nuclear waste and related compensation, while also continuing to reveal the storage site’s buried history,

A proposal for New Mexico to house one of the world’s largest nuclear waste storage facilities has drawn opposition from nearly every indigenous nation in the state. Nuclear Issues Study Group co-founder and Diné organizer Leona Morgan told state legislators in November 2019 the project, if approved, would perpetuate a legacy of nuclear colonialism against New Mexico’s indigenous communities and people of color.
Holtec International, a private company specializing in spent nuclear fuel storage and management, applied for a license from the federal Nuclear Regulatory Commission to construct and operate the facility in southeastern New Mexico. Holtec’s proposal would see the majority of high-level nuclear waste in the U.S. transported to a consolidated interim storage facility located in southeastern New Mexico. If licensed, the facility would house up to 100,000 metric tons of high-level waste at capacity — more nuclear waste than currently exists in the country — for up to 40 years, while the federal government either re-opens Yucca Mountain or establishes a new deep repository to permanently store the waste.
The proposal, which has been in the works since 2011, would see high-level waste generated at nuclear power plants across the country transported to New Mexico for storage at the proposed facility along the Lea-Eddy county line between Hobbs and Carlsbad. Holtec representatives say the facility would be a temporary solution to the nation’s growing nuclear waste problem, but currently there is no federal plan to build a permanent repository for the waste.
Legislators, activists and residents alike share concerns about the proposals. Some fear the “interim” storage facility could become a de facto permanent storage facility if no other repository is built; others question the site selection for a nuclear facility so close to oil and gas activity in the Permian Basin. Increased transport of high-level radioactive waste across the state could also lead to potentially dangerous nuclear releases, leaving impacted communities responsible for emergency responses.
“New Mexico doesn’t make the waste, why should we take the waste?” Morgan said. “What we’re advocating for is not a temporary, band-aid solution, but something more scientifically sound. The waste does have to go somewhere. However, storing it in New Mexico temporarily is not the right idea. It’s not safe; it’s not supported by the local communities; and New Mexico does not want it.” “We see this as environmental racism and perpetuating nuclear colonialism that is going to result in a continuation of a slow genocide,” she said….
Meanwhile, nuclear power utilities across the country have sued the federal government over a breach of contract for failing to establish a permanent repository for the waste.
Nuclear colonialism, a term first coined by environmentalist Winona LaDuke and activist Ward Churchill, describes a systematic dispossession of indigenous lands, the exploitation of cultural resources, and a history of subjugation and oppression of indigenous peoples by a government to further nuclear production of energy and proliferation of weapons. “All of the impacts from nuclear colonialism can be simplified by explaining it as environmental racism,” Morgan told state legislators last week. She pointed to the health and environmental consequences of uranium mining on the Navajo Nation during the last century. “My family lives in areas where there was past uranium mining. We’re still dealing with the legacy of all of the mining that fuelled World War II and the Cold War,” Morgan said. “This legacy is still unaddressed — not just in New Mexico, but in the entire country. For that reason, my concern is the health of our people, our environment.”
“We do not believe we are separate from the environment,” Morgan said. “We are not here to protect the environment as land and as mountains, but as living, breathing entities.” Similar beliefs, sometimes referred to in policy discussions as “environmental personhood,” have gained recognition among regulators in countries across the world in recent years.

From January 2020, the United Nations International Maritime Organization (IMO) will ban ships from using fuels with a sulphur content above 0.5%, compared with 3.5% now.The rules herald the biggest leap in how ships are powered since they switched from burning coal to oil over a century ago, but vessels will still be allowed to use higher-sulphur fuel if fitted with cleaning devices called scrubbers. Closed-loop scrubbers keep most of the water used for sulphur removal onboard for disposal at port. Open-loop systems, however, remove sulphur coming through a ship’s smokestack with water that can then be pumped overboard.
Years of studies have examined whether open-loop scrubbers introduce into waterways acidic sulphur harmful to marine life, cancer-causing hydrocarbons, nitrates leading to algal blooms and metals that impair organ function and cause birth defects. The results have largely been inconclusive and the IMO itself has encouraged further study into the environmental impact of scrubbers.
The stated aim of the new IMO measures is to improve human health.. A study in the journal Nature last year found ship emissions with current sulphur levels caused about 400,000 premature deaths from lung cancer and cardiovascular disease as well as around 14 million childhood asthma cases every year.
Singapore and Fujairah in the United Arab Emirates have banned the use of open-loop scrubbers from the start of next year. China is also set to extend a ban on scrubber discharge to more coastal regions.

Giant oil firms have spent more than four decades pumping billions of pounds worth of oil from the seabed. But now decommissioned rigs in the North Sea are at the centre of an environmental storm with an oil giant under intense pressure to rethink plans to leave some of the platforms in the sea.
Several hundred oil drilling platforms in the waters off Scotland are due to be decommissioned over the next three decades as they approach the end of their operational lifetime. Due to the cost and difficulty of dismantling the structures – each of which can be as tall as the Eiffel Tower – Shell proposed removing only the topside of its four Brent platforms, leaving the huge concrete legs in place.
That resulted in the controversial suggestion that oil mixed with sediment in 42 out of 64 concrete storage cells – each up to 66 feet in diameter and 200 feet high, around the height of the Scott Monument in Edinburgh – should remain on the seabed. These could remain for up to 500 years after the platforms have been decommissioned.
The plans have raised alarm in some quarters over the impact of leaks from the estimated 11,000 tonnes of raw oil and toxins remaining in the base of the four Brent installations – Alpha, Bravo, Charlie and Delta, all put up in the East Shetland basin in the 1970s. It has emerged that a report of an expert evaluation group commissioned by the Dutch government has provided a critical analysis of the position and recommends a clean-up be carried out as agreed more than 20 years ago in international treaties. See Brent Decommissioning Derogation: An evaluation. The special treaty known as Ospar, which was adopted in 1992, states that rigs, including their contents and pipelines, must be removed from the sea after decommissioning.
The experts said that removing all contaminated materials “presents the most certain solution”. They say staying true to Ospar “not only avoids passing on potential problems to future generations” but also prevents “large amounts of negative public attention as was the case in the decommissioning of Brent Spar in the 1990s”. When Shell proposed sinking the Spar oil storage buoy in 1995, it prompted protests by Greenpeace, petrol boycotts in Germany and a falling share price. The company was eventually forced to back down and find a more environmentally friendly plan.
In October 2019, Greenpeace activists from the Netherlands, Germany and Denmark boarded two oil platforms in Shell’s Brent field in a protest against the plans. They scaled Brent Bravo and hung banners saying “Shell, clean up your mess!” and “Stop Ocean Pollution”.
The 2019 report revealed that an earlier independent review group(that took place in 2017)said that a “leave in place” solution with appropriate navigational markers and safety zones gave “a risk in relation to shipping impact that Shell regarded as acceptable”. The report added: “However, although the estimated probabilities of a collision may be low on a per annum basis, the consequences could be catastrophic and result in major injury and loss of life or serious marine pollution.”

A biological remediation pilot project seeking to enhance nature’s own ability to clear up oil spills in Iraq’s conflict-affected areas has been launched in Kirkuk, Iraq…This UNEP initiative seeks to harness naturally occurring soil bacteria as a powerful natural ally to decontaminate poisoned land. Over three years ago in summer 2016, the residents of Qayyarah—a small town of around 25,000 people, some 60 km south of Mosul—were caught in the line of fire as so-called Islamic State fighters torched nineteen nearby oil wells. So thick were the clouds of smoke, that people could not distinguish day from night for weeks in what infamously came to be known as the “Daesh winter”. Rivers of crude oil flowed through Qayyarah’s streets and into seasonal wadis as oil wells spewed tens of thousands of barrels of oil relentlessly for months. The specter of an even worse environmental catastrophe was heightened as the oil slick migrated to less than three kilometers from the Tigris River, Iraq’s water lifeline.
Following an epic battle to control the oil fires that took nearly a year, North Oil Company, which manages the oil fields of northern Iraq, is currently collecting an estimated 20,000 tonnes of remaining oil waste in Qayyarah into around a dozen large pits. Progress, however, has been slow and pools of heavy viscous oil remain on the doorsteps of entire neighborhoods and households, who complain about the impacts of noxious fumes on their children’s health.
“In some places, the layer of heavy oil is two to three meters thick, and long stretches of wadi channels are now effectively tarmac roads on which cars can be driven,” observed Mohammed Dawood, head of Qayarrah oil refinery’s environmental unit. Furthermore, Environment Ministry officials expressed concern that exceptionally heavy rains and flash floods of the 2018/19 winter season washed out oil from the holding pits into the Tigris River.
While oil production restarted in Qayyarah immediately after the conflict ended in June 2017, reaching currently an estimated 40,000 barrels per day, little has been done to clean up the conflict’s toxic aftermath… The UN Environment Programme in collaboration with the UN Assistance Mission in Iraq delivered a four-day hands-on training workshop on remediation of oil spills by the use of bacteria in September 2019. “By adding nutrients from manure, bulking agents like wood chips and water, we are simply creating the ideal conditions for bacteria to thrive and speeding up the natural process of breaking down the oil,”

Numerous international governmental agencies that steer policy assume that polystyrene, a sort of plastic persists in the environment for millennia.
In their research paper published in the Journal of Environmental Science and Technology Letters, scientists show the that polystyrene is completely photochemically oxidized to carbon dioxide and partially photochemically oxidized to dissolved organic carbon. Lifetimes of complete and partial photochemical oxidation are estimated to occur on centennial and decadal time scales, respectively. These lifetimes are orders of magnitude faster than biological respiration of polystyrene and thus challenge the prevailing assumption that polystyrene persists in the environment for millennia.

What to do with the enormous amount of radioactive water, which grows by around 150 tons a day at Fukushima, is a thorny question, with controversy surrounding a long-standing proposal to discharge it into the sea, after extensive decontamination. The water comes from several different sources: Some is used for cooling at the plant, which suffered a meltdown after it was hit by a tsunami triggered by a massive earthquake in March 2011. Groundwater that seeps into the plant daily, along with rainwater, add to the problem.
A thousand, towering tanks have now replaced many of the cherry trees that once dotted the plant’s ground. Each can hold 1,200 tons, and most of them are already full. “We will build more on the site until the end of 2020, and we think all the tanks will be full by around the summer of 2022,” said Junichi Matsumoto, an official with the unit of plant operator TEPCO in charge of dismantling the site.
TEPCO has been struggling with the problem for years, taking various measures to limit the amount of groundwater entering the site. There is also an extensive pumping and filtration system, that each day brings up tons of newly contaminated water and filters out as many of the radioactive elements as possible.
The hangar where the decontamination system runs is designated “Zone Y” — a danger zone requiring special protections. All those entering must wear elaborate protection: a full body suit, three layers of socks, three layers of gloves, a double cap topped by a helmet, a vest with a pocket carrying a dosimeter, a full-face respirator mask and special shoes. Most of the outfit has to burned after use.
“The machinery filters contain radionuclides, so you have to be very protected here, just like with the buildings where the reactors are,” explained TEPCO risk communicator Katsutoshi Oyama. TEPCO has been filtering newly contaminated water for years, but much of it needs to go through the process again because early versions of the filtration process did not fully remove some dangerous radioactive elements, including strontium 90.
The current process is more effective, removing or reducing around 60 radionuclides to levels accepted by the International Atomic Energy Agency (IAEA) for water being discharged. But there is one that remains, which cannot be removed with the current technology: tritium.
Tritium is naturally present in the environment, and has also been discharged in its artificial form into the environment by the nuclear industry around the world. There is little evidence that it causes harm to humans except in very high concentrations and the IAEA argues that properly filtered Fukushima water could be diluted with seawater and then safely released into the ocean without causing environmental problems.
But those assurances are of little comfort to many in the region, particularly Fukushima’s fishing industry which, like local farmers, has suffered from the outside perception that food from the region is unsafe.

The Louisiana University Marine Consortium (LUMCON) published in September 2019 a study on the Deepwater Horizon Oil Spill in Royal Society Open Science. The BP’s Deepwater Horizon oil rig exploded in April 2010, killing 11 workers. The subsequent cleanup and restoration had cost nearly $65 billion..but while while we can burn off and disperse oil on the surface, but we don’t have the technology to get rid of oil on the seafloor. So approximately 10 million gallons of it settled there….In 2017 , the The LUMCON surveyed the site surrounding the wreck of the rig, and another one 1,640 feet north. There were no giant isopods, glass sponges, or whip corals that would have jumped (metaphorically) at the chance to colonize the hard substrate of the rig, such as discarded sections of pipe…..But] crabs were just about everywhere. The researchers were shocked by the sheer number of crustaceans and other arthropods that had colonized the spill site. According to rough estimates, Atlantic deep sea red crabs, red shrimp, and white caridean shrimp were nearly eight times more populous at the Deepwater site than at other spots in the Gulf. “Everywhere there were crabs just kicking up black plumes of mud, laden with oil,” Nunnally says. But abundance does not mean the site was recovering, or even friendly to life. Particularly eerie was the crab’s achingly slow movement. “Normally, they scatter when they see the ROV lights,” he says. But these crabs seemed unbothered, or unaware of the robot’s presence.
The researchers hypothesize that degrading hydrocarbons are what’s luring unwitting crabs from the surrounding seafloor to the deep-sea equivalent of a toxic dump. “The chemical makeup of oil is similar to the oils naturally present on crustaceans,” Nunnally says. “They’re attracted to the oil site, but everything goes downhill for them once they’re in the area.” A similar kind of chemical confusion occurred at an oil spill in Buzzards Bay in New England in 2003, which attracted hordes of American lobsters. The researchers liken the death trap to the La Brea Tar Pits: Once lured in, the crabs lose their ability to leave. With no other species able to thrive in the area, the crabs have no food source—except each other. And as one might imagine, consuming the flesh of a toxin-riddled crab or starving to death in a deep-sea tar pit is sort of a lose/lose situation.
The crabs also looked anything but normal: some claws shrunken, some swollen, shriveled legs, a dusting of parasites. “There were deformities, but mostly things were missing,” Nunnally says. “You come in with eight legs and try to get away on four or five.” The researchers have yet to ascertain what specific toxins led to these maladies. The shrimp looked just as awful as the crabs. “They didn’t look like shrimp from other sites,” Nunnally says, adding that many of the small crustaceans had humps in their backs—tumors, perhaps.

The U.S. Department of Energy (DOE) announced on Aug. 15, 2019 the launch of the National Reactor Innovation Center (NRIC). The new initiative will assist with the development of advanced nuclear energy technologies by harnessing the world-class capabilities of the DOE national laboratory system. Authorized by the Nuclear Energy Innovation Capabilities Act, NRIC will provide private sector technology developers the necessary support to test and demonstrate their reactor concepts and assess their performance. This will help accelerate the licensing and commercialization of these new nuclear energy systems.
“NRIC will enable the demonstration and deployment of advanced reactors that will define the future of nuclear energy,” said U.S. Energy Secretary Rick Perry. “By bringing industry together with our national labs and university partners, we can enhance our energy independence and position the U.S. as a global leader in advanced nuclear innovation.” NRIC will be led by Idaho National Laboratory and builds upon the successes of DOE’s Gateway for Accelerated Innovation in Nuclear (GAIN) initiative…
The Nuclear Energy Innovation Capabilities Act was signed into law in 2018 by President Donald J. Trump and eliminates some of the financial and technological barriers standing in the way of nuclear innovation. It directs DOE to facilitate the siting of advanced reactor research demonstration facilities through partnerships between DOE and private industry. The House Energy and Water Development committee has allocated $5 million in the FY2020 budget for NRIC, which plans to demonstrate small modular reactor and micro-reactor concepts within the next five years.

Small modular nuclear reactors (SMRs) are relatively small and flexible: they have a power capacity of up to 300 MW(e) and their output can fluctuate in line with demand. This makes them particularly attractive for remote regions with less developed grids, but also for use as a complement to renewables and for non-electric applications of nuclear power. SMRs can be manufactured and then shipped and installed on site, so they are expected to be more affordable to build.
Globally, there are about 50 SMR designs and concepts at different stages of development. Three SMR plants are in advanced stages of construction or commissioning in Argentina, China and Russia, which are all scheduled to start operation between 2019 and 2022…Some SMR designs have features that could reduce the tasks associated with spent fuel management. Power plants based on these designs require less frequent refuelling, every 3 to 7 years, in comparison to between 1 and 2 years for conventional plants, and some are even designed to operate for up to 30 years without refuelling. Nevertheless, even in such cases, there will be some spent fuel left, which will have to be properly managed.

In August 2019, Tepco projected that storage of radioactive water at the Fukushima nuclear plant would reach full capacity by around summer 2022 even after the expansion — the first time it has issued such a precise estimate. According to Tepco, the Fukushima No. 1 plant had 960 massive tanks containing 1.15 million tons of treated water as of July 18, 2019. Water that has touched the highly radioactive melted fuel debris has been cleaned up through water treatment machines and is stored in the tanks, but the high-tech treatment machines are able to remove most radionuclides except tritium. The plant currently sees an increase of contaminated water by 170 tons a day, Tepco says.
Releasing tritium-tainted water into the sea in a controlled manner is common practice at nuclear power plants around the world, and it was generally considered the most viable option as it could be done quickly and would cost the least. The head of the Nuclear Regulation Authority, Toyoshi Fuketa, has long said that releasing the treated water into the sea is the most reasonable option, but people in Fukushima, especially fishermen, fear it will damage the region’s reputation.
Addressing those concerns, the government panel, launched in November 2016, has been looking for the best option in terms of guarding against reputational damage. Injecting it into the ground, discharging it as steam or hydrogen, or solidification followed by underground burial have all been on the table. Under the current plan, Tepco is set to increase the tank space to store 1.37 million tons of water a total, but estimates show that will only last until summer 2022. But the more space it creates, the bigger the decommissioning headache becomes.

Cigarette butts, the most littered items in the world, are posing an intractable trash problem for regulators and tobacco companies: Throwing them on the ground is a firmly entrenched habit for many smokers. Regulators are taking a tougher stance on cigarette filter pollution amid concerns about the environmental impact of single-use plastic. Butts for decades have been made from cellulose acetate, a form of plastic, which takes years to break down. Studies show that butts—which often wash from sidewalks into drains and then waterways—can be toxic to fish.
About 65% of cigarettes smoked in the U.S. are littered, according to Keep America Beautiful, a nonprofit whose cigarette litter prevention program is funded by the tobacco industry. “That whole habit is so ingrained it becomes part of the ritual of taking the cigarette out of the pack, lighting it, smoking it, putting it on the ground,” said Christopher Proctor, chief scientific officer at British American Tobacco (BAT), whose cigarette brands include Kent, Newport and Camel. “Changing ingrained behavior is a really difficult thing to do.”
The European Union in May adopted new rules under which members must pass laws within two years requiring tobacco companies to fund the cleanup of filter litter as part of a broader crackdown on single-use plastics. A bill proposing banning filters has made its way through the California Senate and will be heard by the lower house next year. In response, BAT and Japan Tobacco Inc. are testing biodegradable filters, while Philip Morris International Inc. is assessing the appetite for portable ashtrays. Companies also are tapping behavioral psychologists to understand what propels smokers to litter, hoping to forestall stricter regulation…
he World Health Organization says that when filters do break down they leach out some of the 7,000 chemicals contained in cigarettes, many of which are environmentally toxic.

Across India, from poor villages to expensive residential areas of cities, millions of trash pickers are at work to collect what other people dispose. They are called raddiwalas, ragpickers, scavengers and waste managers. Some go door-to-door, others gather iron rebar and used bricks on construction sites, still others clean parks and city streets. There are even specialists who gather hair, which is exported in bulk for wigs. They’re the starting point of a multilayered, $25 billion industry in India that advances through increasingly specialized middlemen and industrialists to eventually turn garbage into new objects. The work is a moneymaker for conglomerates as well as a route out of poverty for some of India’s poorest people.
All of that has been upended by a crash in a global garbage market dominated by two players: China, which buys most of the world’s garbage, and the U.S., which sells the most. Last year, China dramatically cut the amount of garbage it buys. The reduced demand from China and continued supply from the U.S. flooded the world trash market and drove down the price of garbage everywhere….Indian recycling companies took advantage of the deep discounts and started importing more trash from the U.S. and elsewhere. In 2018, the imports of mixed scrap plastic to India rose 33%. The jump in supply pushed prices down for the low-end Indian workers who pick through mountains of locally produced trash for raw materials to sell.
That’s impacting an Indian trash economy powerful enough to have prompted its own migration pattern: thousands of families left their rural villages to collect garbage in cities. Now, with their garbage hauls worth less, many are returning home. For the pickers, the going price for a kilo, or 2.2 pounds, of plastic water bottles, which used to bring around 45 rupees—roughly 65 cents—is now worth only about 25 rupees—or 36 cents.The trash glut also lowered profits for industrial recycling companies who turn the trash into usable materials. Plastic pellets, the end-product after processing some plastic scrap, went from 80 rupees to 45 rupees a kilo.
China ratcheted up restrictions on imports of recyclable materials to force its recycling industry to absorb more of the waste generated within the country. China also is nudging the country away from the role of accepting others’ garbage, which is viewed as a dirty industry. The global trash glut means India’s own trash is worth less to its domestic recyclers.

Agitations against the Kudankulam nuclear plant broke out in June 2019. Villages around the contentious reactors moved a resolution to put a stop to the government’s plans to construct an Away From Reactor (AFR) facility on the premises of the nuclear power plant. The AFR is a storage unit meant to store spent fuel generated at the two nuclear plants in Kudankulam… While resolutions passed at four villages – Kavalkinar, Vadakankulam, Perumanal and Kudankulam were recorded by district authorities, a similar move in the village of Vijayapathi was stopped. The decision led to protests in the village and was forcefully dispersed by the police. …
A public hearing regarding the AFR scheduled for July 10, 2019 was recently postponed indefinitely. A look at the circular shows that only two villages were invited – Kudankulam and Vijayapathi. Activists allege that this was an intentional attempt to shut down dissent against the proposed facility.
The resolutions included – opposition to collection of nuclear waste in Kudankulam, demand to stop construction of an AFR facility and demand to permanently shut down the plant. Opposition parties and activists had urged the Centre to come out with a detailed plan for setting up a permanent deep geological repository and drop the plan of a proposed Away From Reactor facility. “This entire exercise is meant to create storage for spent fuel and an AFR is only a temporary solution till the government finds land to build a deep geological repository,” explains Sundarrajan. “But across the country, no state is ready to risk giving land for permanent disposal of nuclear waste. So, residents fear that this will used as an excuse by the government to make the AFR a permanent storage space.”

According to DARPA, terrorist attacks involving the use of proliferated radiological and special nuclear materials pose a potential threat to U.S. citizens and servicemembers. Early detection of such materials and devices made from them is a critical part of the U.S. strategy to prevent attacks. Lower-cost and more sensitive detectors, along with innovative deployment strategies, could significantly enhance detection and deterrence of attack.
The SIGMA program aims to revolutionize detection and deterrent capabilities for countering nuclear terrorism. A key component of SIGMA thus involves developing novel approaches to achieve low-cost, high-efficiency, packaged radiation detectors with spectroscopic gamma and neutron sensing capability. The program will seek to leverage existing infrastructure to help enable these next-generation detectors and their deployment in order to demonstrate game-changing detection and deterrent systems.

Northern Norway saw a record number of 12 visiting NATO nuclear-powered submarines in 2018. The subs are in for supplies or crew change before continuing the cat-and-mouse hunt for Russian submarines sailing out in the strategically important waters between Norway, Iceland and Greenland. It was here, in international waters outside Senja in Troms, the Russian Echo-II class submarine K-192 suffered a severe reactor coolant accident 30 years ago, on June 26th 1989. Radioactive iodine was leaking with the reactor-steam while the vessel was towed around the coast of northernmost Norway to the navy homeport at the Kola Peninsula.
Fearing similar accidents could happen again, Norway is pushing for international awareness to..A dedicated group, named ARCSAFE, was established under the Arctic Council in 2015 aimed at sharing knowledge and experiences between national radiation authorities and other rescue services.“Norway has suggested to form an expert group, where one of the tasks could be to look into a possible Arctic Council agreement for radiation emergencies, like already exists for oil spill and search- and rescue cooperation,” says Øyvind Aas-Hansen.
Meanwhile, international experts on radiation monitoring teamed up with industry developers looking at the potential for using unmanned aerial vehicles (UAVs) in the Arctic. …Some environments are too risky for humans to survey and collect data. A nuclear accident site is one such spot, also if it happens at sea. UAVs, better known as drones, could carry a geiger counter, camera or other tools in the air over hazardous objects like a submarine on fire. From safe distance, emergency response units could then be better prepared before boarding or sailing close-up.
The Barents Observer has recently published an overview listing the increasing number of reactors in the Russian Arctic. According to the list there are 39 nuclear-powered vessels or installations in the Russian Arctic today with a total of 62 reactors. This includes 31 submarines, one surface warship, five icebreakers, two onshore and one floating nuclear power plants. Looking 15 years ahead, the number of ships, including submarines, and installations powered by reactors is estimated to increase to 74 with a total of 94 reactors, maybe as many as 114. Additional to new icebreakers and submarines already under construction, Russia is brushing dust of older Soviet ideas of utilizing nuclear-power for different kind of Arctic shelf industrial developments, like oil- and gas exploration, mining and research. “By 2035, the Russian Arctic will be the most nuclearized waters on the planet,” the paper reads.
Other plans to use nuclear reactors in the Russian Arctic in the years to come include many first-of-a-kind technologies like sea-floor power reactors for gas exploration, civilian submarines for seismic surveys and cargo transportation, small-power reactors on ice-strengthen platforms.
In the military sphere, the Arctic could be used as testing sites for both Russia’s new nuclear-powered cruise-missile and nuclear-powered underwater weapons drone. Both weapons were displayed by President Vladimir Putin when he bragged about new nuclear weapons systems in his annual speech to the Federation Council last year.
For Norway and Russia, a nuclear accident in the Barents Sea could be disastrous for sales of seafood. The two countries export of cod and other spices is worth billions of Euros annually.

Four Chinese-run gold mines should be closed in the Central African Republic because of pollution threatening public health, a parliamentary panel said in a report published on July 14, 2019. “Ecological disaster,” “polluted river,” “public health threatened,” were some of the phrases used in the report. “Gold mining by the Chinese firms at Bozoum is not profitable for the state and harmful to the population and the environment,” the commission found after its investigation into mining in the northern town. “The nature of the ecological disaster discovered onsite justifies the immediate, unconditional halt to these activities,” the report found.
Members of the commission spent four days in Bozoum a month ago in response to “multiple complaints from the population.” There, they found a badly polluted River Ouham, shorn of several aquatic species following the excavation of its riverbed. They discovered that a rising death rate in fishing villages as well as shrinking access to clean drinking water.
The investigators also voiced fears that the country’s “resources are being squandered with the complicity of certain ministry of mines officials.” The CAR is rich in natural resources but riven by conflict which has forced around one in four of its 4.5 million population to flee their homes. Under those circumstances, exploitation of the country’s natural resources is difficult to monitor effectively given that the state only has partial control of its own territory.

Breakthroughs in the science of programmable gene expression inspired DARPA to establish the PReemptive Expression of Protective Alleles and Response Elements (PREPARE) program with the goal of delivering powerful new defenses against public health and national security threats. DARPA has now selected five teams to develop a range of new medical interventions that temporarily and reversibly modulate the expression of protective genes to guard against acute threats from influenza and ionizing radiation, which could be encountered naturally, occupationally, or through a national security event.
The program builds from the understanding that the human body has innate defenses against many types of health threats, but that the body does not always activate these defenses quickly or robustly enough to block the worst damage. To augment existing physiological responses, PREPARE technologies would provide a programmable capability to up- or down-regulate gene expression on demand, providing timely, scalable defenses that are proportional to anticipated threats. Service members and first responders could administer these interventions prior to threat exposure or therapeutically after exposure to mitigate the risk of harm or death.
Influenza: “Researchers working within the PREPARE program seek to improve rates of survival and recovery in catastrophic scenarios for which reliable and scalable countermeasures don’t currently exist,” said Dr. Renee Wegrzyn, the PREPARE program manager….Three PREPARE teams are pursuing multi-pronged approaches to influenza defense and treatment that use programmable gene modulators to boost the human body’s natural defenses against influenza and also weaken the virus’ ability to cause harm by directly neutralizing the viral genomes. If successful, their approaches would potentially protect against virtually all influenza strains — regardless of whether a virus is newly emergent or has developed drug resistance — and would provide near instantaneous immunity, in contrast to traditional vaccines. Additionally, the teams are designing their countermeasures so that they are simple to deliver — for example, as intranasal sprays — reducing the logistical challenge of protecting large numbers of people.A team led by DNARx LLC, under principal investigator Dr. Robert Debs, aims to develop a new DNA-encoded gene therapy that helps patients fight influenzaby boosting the natural immune response and other protective functions of their nasal passages and lungs.
Ionizing Gamma Radiation: Other PREPARE teams are pursuing treatments to protect the body from the effects of ionizing gamma radiation. In humans, radiation poisoning primarily affects stem cells in the blood and gut, yet existing treatments only help to regenerate blood cells, and only with limited effect. There is no possibility for prophylactic administration of these drugs, and most must be delivered immediately following radiation exposure to provide any benefit. There are no existing medical countermeasures for radiation damage to the gut… A team led by the University of California, San Francisco, under principal investigator Dr. Jonathan Weissman, also aims to develop gene therapies to enhance resilience against ionizing radiation. The team’s approach should result in an intravenous or orally available treatment that activates innate defenses in gut and blood stem cells for a period of several weeks.

The site for Posiva’s repository at Eurajoki for the disposal of Finland’s high-level radioactive waste (used nuclear fuel), near the Olkiluoto nuclear power plant, was selected in 2000. The Finnish parliament approved the the repository project the following year in 2001… The government granted a construction licence for the project in November 2015 and construction work on the repository started iin 2016. Posiva’s plan is for used nuclear fuel to be packed inside copper-steel canisters at an above-ground encapsulation plant, from where they will be transferred into the underground tunnels of the repository, located at a depth of 400-450 meters, and further into deposition holes lined with a bentonite buffer. Operation of the repository is expected to begin in 2023. The cost estimate of this large-scale construction project totals about EUR500 million (USD570 million), the company said.
Posiva announced on June 25, 2019 the start of construction of the used fuel encapsulation plant. Janne Mokka, Posiva’s President, noted, “In Finland, full lifecycle management of nuclear fuel is a precondition for the production of climate-friendly nuclear electricity. Posiva will execute the final disposal of the spent fuel of its owners’ Olkiluoto and Loviisa nuclear power plants responsibly.”
Sweden is planning a similar used fuel encapsulation and disposal facility using the same storage method. Under its current timetable, national radioactive waste management company Svensk Kärnbränslehantering AB plans to start construction of the used fuel repository and the encapsulation plant sometime early in the 2020s and they will take about 10 years to complete.

‘Plasticrusts’ are see on the surface of rocks in Madeira island, Portugal. Researchers say they may have identified a new kind of plastic pollution in the sea, and they’re calling it “plasticrust.” Scientists working on Madeira, a volcanic Portuguese island off northwest Africa, have found small patches of what look like melted plastic encrusted on rocks along the shoreline.

There is no point collecting recyclable waste unless someone is willing to buy it and actually do the recycling. Until late 2017 China was the world’s biggest importer of scrap by far. All this came to a halt when the Chinese government banned the import of all but the purest scrap material in 2017, killing a trade worth $24bn a year. Waste dealers in the rich world had to scramble to find new buyers. South-East Asia soon emerged as the pre-eminent destination for foreign waste. Unfortunately, the region’s recycling industry is much smaller than China’s; its processing plants were quickly overwhelmed. Plastics from America and Europe have piled up in landfills. Lots of toxic rubbish has simply been torched.
South-East Asian governments are not pleased. They have begun to ban or crimp imports themselves, abruptly diminishing a booming business. On May 28th, 2919 Yeo Bee Yin, Malaysia’s environment minister, complaining that “garbage [was] being traded under the pretext of recycling”, announced that her government would be sending back 3,000 tonnes of foreign plastic. Much of it was of poor quality, she noted, and hence unrecyclable. Thailand plans to ban plastic-waste imports by 2021. Vietnam’s government has similar ideas. Kate O’Neill of the University of California, Berkeley, reckons these bans are motivated not only by environmental concerns but also by pride: Asia does not want to be the world’s dumping ground. Rodrigo Duterte, the president of the Philippines, recently threatened to go to war with Canada if it did not take back a shipment of plastic scrap. Canada agreed to take it away…

CFC-11 is also known as trichlorofluoromethane, and is one of a number of chloroflurocarbon (CFC) chemicals that were initially developed as refrigerants during the 1930s. However, it took many decades for scientists to discover that when CFCs break down in the atmosphere, they release chlorine atoms that are able to rapidly destroy the ozone layer which protects us from ultraviolet light. A gaping hole in the ozone layer over Antarctica was discovered in the mid 1980s. The international community agreed the Montreal Protocol in 1987, which banned most of the offending chemicals. Recent research suggests that the hole in the Northern Hemisphere could be fully fixed by the 2030s and Antarctica by the 2060s.
CFC-11 was the second most abundant CFCs and was initially seen to be declining as expected.However in 2018 a team of researchers monitoring the atmosphere found that the rate of decline had slowed by about 50% after 2012. Further detective work in China by the Environmental Investigation Agency in 2018 seemed to indicate that the country was indeed the source. They found that the illegal chemical was used in the majority of the polyurethane insulation produced by firms they contacted.One seller of CFC-11 estimated that 70% of China’s domestic sales used the illegal gas. The reason was quite simple – CFC-11 is better quality and much cheaper than the alternatives.
This new paper seems to confirm beyond any reasonable doubt that some 40-60% of the increase in emissions is coming from provinces in eastern China. Using what are termed “top-down” measurements from air monitoring stations in South Korea and Japan, the researchers were able to show that since 2012 CFC-11 has increased from production sites in eastern China.They calculated that there was a 110% rise in emissions from these parts of China for the years 2014-2017 compared to the period between 2008-2012.
“If we look at these extra emissions that we’ve identified from eastern China, it equates to about 35 million tonnes of CO2 being emitted into the atmosphere every year, that’s equivalent to about 10% of UK emissions, or similar to the whole of London.” The Chinese say they have already started to clamp down on production by what they term “rogue manufacturers”. In November 2018, several suspects were arrested in Henan province, in possession of 30 tonnes of CFC-11.

The Mobil Foundation sought to use its tax-exempt grants to shape American laws and regulations on issues ranging from the climate crisis to toxic chemicals – with the explicit goal of benefiting Mobil, documents obtained by the Guardian newspaper show. Recipients of Mobil Foundation grants included Ivy League universities, branches of the National Academies and well-known civic organizations and environmental researchers. Benefits for Mobil included – in the foundation’s words – funding “a counterpoint to so-called ‘public interest’ groups”, helping Mobil obtain “early access” to scientific research, and offering the oil giant’s executives a forum to “challenge the US Environmental Protection Agency (EPA) behind-the-scenes”….
A third page reveals Mobil Foundation’s efforts to expand its audience inside environmental circles via a grant for the Environmental Law Institute, a half-century-old organization offering environmental law research and education to lawyers and judges. “Institute publications are widely read in the environmental community and are helpful in communicating industry’s concerns to such organizations,” the entry says. “Mobil Foundation grants will enhance environmental organizations’ views of Mobil, enable us to reach through ELI activities many groups that we do not communicate with, and enable Mobil to participate in their dialogue groups.”
The documents also show Mobil Foundation closely examining the work of individual researchers at dozens of colleges and universities as they made their funding decisions, listing ways that foundation grants would help shape research interests to benefit Mobil, help the company recruit future employees, or help combat environmental and safety regulations that Mobil considered costly. “It should be a wake-up call for university leaders, because what it says is that fossil fuel funding is not free,” said Geoffrey Supran, a postdoctoral researcher at Harvard and MIT. “When you take it, you pay with your university’s social license,” Supran said. “You pay by helping facilitate these companies’ political and public relations tactics.”
In some cases, the foundation described how volunteer-staffed not-for-profits had saved Mobil money by doing work that would have otherwise been performed by Mobil’s paid staff, like cleaning birds coated in oil following a Mobil spill. In 1987, the International Bird Rescue Research Center’s “rapid response and assistance to Mobil’s West Coast pipeline at a spill in Lebec, CA not only defused a potential public relations problem”, Mobil Foundation said, “but saved substantial costs by not requiring our department to fly cross country to respond”.d of trustees at the Woods Hole Oceanographic Institution (recipient of listed donations totalling over $200,000 from Mobil) and a part of UN efforts to study climate change.
Wise ultimately co-authored two UN Intergovernmental Panel on Climate Change reports, serving as a lead author on one. One report chapter Wise co-authored prominently recommended, among other things, burning natural gas (an ExxonMobil product) instead of coal as a way to combat climate change.

The cost of cleaning up pollution from nuclear weapons manufacturing is estimated to be $377 billion. This reflects cleanup cost estimates for 16 sites across the United States. Two of these, the Hanford site in Washington and Savannah River site in South Carolina, have most of nuclear waste stored in tanks, which is particularly costly and complicated to treat.
These clean up costs grew by $214 billion between 2011 and 2018 and they will continue to grow for several reasons including the lack of a program-wide cleanup strategy and reliance primarily on individual sites to locally negotiate cleanup activities and establish priorities. For example, the Hanford and Savannah River sites plan to treat similar radioactive tank waste differently, with Hanford’s efforts possibly costing tens of billions more than Savannah River’s. In addition, the government manages most of its cleanup work as operations activities, under less stringent requirements than other environmental remediation projects. For example, operations activities are not subject to independent oversight.
Companies specializing in the handling of radioactive material are buying retired U.S. nuclear reactors from utilities and promising to clean them up and demolish them in dramatically less time than usual — eight years instead of 60, in some cases. Turning nuclear plants over to outside companies and decommissioning them on such a fast track represents a completely new approach in the United States, never before carried to completion in this country, and involves new technology as well…
Once a reactor is shut down, the radioactive mess must be cleaned up, spent nuclear fuel packed for long-term storage and the plant itself dismantled. The most common approach can last decades, with the plant placed in a long period of dormancy while radioactive elements slowly decay. Spent fuel rods that can no longer sustain a nuclear reaction remain radioactive and still generate substantial heat. They are typically placed in pools of water to cool, staying there for at least five years, with 10 years the industry norm, according to the Nuclear Regulatory Commission. After that, they are removed and placed in giant cylindrical casks, typically made of steel and encased in concrete.
But Holtec International, which in the past year has been buying up several retired or soon-to-be-retired nuclear plants in the U.S., has designed a cask it says can accept spent fuel after only two years of cooling. Holtec struck a deal last year to buy Oyster Creek in Forked River, New Jersey, from its owner, Exelon Generation. It also has deals in place to buy several plants owned by Entergy Corp., including: Pilgrim, in historic Plymouth, Massachusetts, closing May 31; Palisades, in Covert, Michigan, set to shut down in 2022 ; and two reactors expected to close within two years at Indian Point in Buchanan, New York…. NorthStar Group Services, a specialist in nuclear demolition, completed the purchase of Vermont Yankee from Entergy with plans for its accelerated decommissioning.
The companies jumping into the business believe they can make in profit….Holtec will inherit the multibillion-dollar decommissioning trust funds set up by the utilities for the plants’ eventual retirement. , The company would be able to keep anything left over in each fund after the plant’s cleanup. By Holtec’s accounting, for instance, the Pilgrim decommissioning will cost an estimated $1.13 billion, leaving $3.6 million in the fund. Holtec and Northstar are also banking on the prospect of recouping money from the federal government for storing spent fuel during and after the decommissioning, because there is no national disposal site for high-level nuclear waste…
Holtec has come under scrutiny over its role in a mishap in August 2018 during the somewhat less aggressive decommissioning of the San Onofre plant in Southern California, where two reactors were retired in 2013 and the estimated completion date is 2030….Holtec contractors were lowering a 45-ton spent fuel cask into an underground storage vault at San Onofre when it became misaligned and nearly plunged 18 feet, investigators said. No radiation was released. Federal regulators fined Southern California Edison, the plant’s owner, $116,000, and an investigation found that some Holtec procedures had been inadequate or not properly followed.

The Bravo test, the testiong of a nuclear bomb on March 1, 1954, in the Bikini Atoll of the Marshall Islands resulted in an explosion that was 2½ times larger than expected. Radioactive ash dropped more than 7,000 square miles from the bomb site, caking the nearby inhabited islands. “Within hours, the atoll was covered with a fine, white, powder-like substance,” the Marshall Islands health minister would later testify, according to the Atomic Heritage Foundation. “No one knew it was radioactive fallout. The children played in the ‘snow.’ They ate it.”
The 1954 explosion was part of nuclear tests conducted as the American military lurched into the nuclear age. From 1946 o 1958, 67 U.S. nuclear tests were conducted in the Marshall islands….From 1977 to 1980, loose waste and top soil debris scraped off from six different islands in the Enewetak Atoll was transported to Runit island and was mixed with concrete and buried in nuclear blast crater. 4,000 US servicemen were involved in the cleanup that took three years to complete. The waste-filled crater was finally entombed in concrete. The Runit Dome, also called locally “The Tomb”, is a 46 cm (18 in) thick dome of concrete at sea level, encapsulating an estimated 73,000 m3 (95,000 cu yd) of radioactive debris, including some plutonium-239. …The structure, however, was never meant to last. Today, due to disrepair and rising sea tides, it is dangerously vulnerable. A strong storm could breach the dome, releasing the deadly legacy of America’s nuclear might….
Cracks have reportedly started to appear in the dome. Part of the threat is that the crater was never properly lined, meaning that rising seawater could breach the structural integrity. “The bottom of the dome is just what was left behind by the nuclear weapons explosion,” Michael Gerrard, the chair of Columbia University’s Earth Institute, told the ABC. “It’s permeable soil. There was no effort to line it. And therefore, the seawater is inside the dome.
According to Guterres, UN Secretary General, who refers to Runit Dome as nuclear coffin: The Pacific was victimized in the past as we all know, The consequences of these have been quite dramatic, in relation to health, in relation to the poisoning of waters in some areas.”

South Korea, which is roughly the size of Indiana, eventually became the most reactor-dense country in the world, with 23 reactors providing about 30% of the country’s total electricity generation…. South Korea’s reactors…are mostly packed into a narrow strip along the densely populated southeastern coast. The density was a way of cutting costs on administration and land acquisition. But putting reactors close to one another—and to large cities—was risky. …
In December 2009, the UAE had awarded a coalition led by Korea Electric Power Corporation (KEPCO) a $20 billion bid to build the first nuclear power plant in the UAE. Barakah was chosen as the site to build four APR-1400nuclear reactors successively. In 2012 to Park Geunhye the newly elected president pledged to increase South Korea’s reactor fleet to 39 units by 2035 and making sales trips to potential client states such as the Czech Republic and Saudi Arabia bulding on prior success like the UAE deal mentioned above. …
But on September 21, 2012, officials at Korea Hydro & Nuclear Power (KHNP), a subsidiary of the Korea Electric Power Corporation (KEPCO), received an outside tip about illegal activity among the company’s parts suppliers. Eventually, an internal probe had become a full-blown criminal investigation. Prosecutors discovered that thousands of counterfeit parts had made their way into nuclear reactors across the South Korea, backed up with forged safety documents. KHNP insisted the reactors were still safe, but the question remained: was corner-cutting the real reason they were so cheap?
Park Jong-woon, a former manager who worked on reactors at KEPCO and KHNP until the early 2000s, believed so. He had seen that taking shortcuts was precisely how South Korea’s headline reactor, the APR1400, had been built…After the Chernobyl disaster in 1986, most reactor builders had tacked on a slew of new safety features.KHNP followed suit but later realized that the astronomical cost of these features would make the APR1400 much too expensive to attract foreign clients.“They eventually removed most of them,” says Park, who now teaches nuclear engineering at Dongguk University. “Only about 10% to 20% of the original safety additions were kept.” Most significant was the decision to abandon adding an extra wall in the reactor containment building—a feature designed to increase protection against radiation in the event of an accident. “They packaged the APR1400 as ‘new’ and safer, but the so-called optimization was essentially a regression to older standards,” says Park. “Because there were so few design changes compared to previous models, [KHNP] was able to build so many of them so quickly.”
Having shed most of the costly additional safety features, KEPCO was able to dramatically undercut its competition in the UAE bid, a strategy that hadn’t gone unnoticed. After losing Barakah to KEPCO, Areva CEO Anne Lauvergeon likened the Korean nuclear plant to a car without airbags and seat belts. At the time Lauvergeon’s comments were dismissed as sour words from a struggling rival.
By the time it was completed in 2014, the KHNP inquiry had escalated into a far-reaching investigation of graft, collusion, and warranty forgery; in total, 68 people were sentenced and the courts dispensed a cumulative 253 years of jail time. Guilty parties included KHNP president Kim Jong-shin, a Kepco lifer, and President Lee Myung-bak’s close aide Park Young-joon, whom Kim had bribed in exchange for “favorable treatment” from the government.
Several faulty parts had also found their way into the UAE plants, angering Emirati officials. “It’s still creating a problem to this day,” Neilson-Sewell, the Canadian advisor to Barakah, told me. “They lost complete faith in the Korean supply chain.”
Gerard Mourou—one of the three winners of the 2018 Nobel Prize for Physics—claims that the lifespan of radioactive waste could potentially be cut to minutes from thousands of years. Although Mourou, 74, is quick to say that the laser option for nuclear waste that he and Irvine, California-based Professor Toshiki Tajima are working on may be years away, its promise has created a flurry of excitement for the sector in France.
Environmental group Greenpeace estimates that there’s a global stockpile of about 250,000 tons of toxic spent fuel spread across 14 countries, based on data from the International Atomic Energy Agency. Of that, 22,000 cubic meters—roughly equivalent to a three-meter tall building covering an area the size of a soccer pitch—is hazardous, according to the IAEA. A 2015 report by GE-Hitachi put the cost of disposing nuclear waste—outside of China, Russia and India—at well over $100 billion. France produces more nuclear waste per-capita than any other country. With almost 72 percent of its electricity coming from nuclear energy—the most in the world—it generates 2 kilograms of radioactive waste per person each year. And although only a fraction of that is highly toxic, more than 60 years after getting into nuclear energy, the country still has no definitive way to cope with it.
In April 2019, France opened its third national debate on nuclear waste, bringing together policy makers, advocacy groups and scientists to discuss handling an estimated 10,000 cubic meters of radioactive waste collectively produced by the country’s 58 reactors over their lifespan. And that doesn’t include atomic material generated by the military and medical sectors.
The most toxic parts are stored right now in short-term facilities in La Hague in Normandy, in Marcoule and Cadarache in southern France and in Valduc, near Dijon. At the facility in La Hague, an hour’s drive from the D-Day beaches, specially designed robots cast the most radioactive nuclear waste into glass casings before putting them in inox containers. Already the world’s largest facility for processing atomic waste, it is constantly being expanded—making a long-term solution urgent.
State-controlled nuclear entities Electricite de France SA and Orano SA, charged with nuclear waste management, and CEA, France’s Atomic Energy Agency, have spent billions on the toxic material. At least another 25 billion euros ($28 billion) is set to be plowed into an underground maze of tunnels near the village of Bure in northeastern France that could be the final resting place for the highly toxic waste starting in 2025. Like with other deep storage sites in place, under construction or being considered in countries including the U.S., Japan, Finland and Sweden, the Bure plan has drawn protests. Greenpeace has pointed to several risks, not least of which being the chance of the toxic material seeping into the groundwater or a fire releasing radioactive gases.
Enter Mourou, with his high-intensity laser option. The physicist’s work has paved the way for the shortest and most-intense laser pulses ever created. In his Nobel Lecture on Dec. 8, Mourou laid out his vision for using his “passion for extreme light” to address the nuclear-waste problem. The process he and Tajima are working on is called transmutation, which involves changing the composition of an atom’s nucleus by bombarding it with a laser. “It’s like karate—you deliver a very strong force in a very, very brief moment,” said Mourou…Transmutation research has been going on for three decades, with efforts in the U.K., Germany, Belgium, U.S. and Japan either failing or in various stages of study…“I can imagine that the physics might work, but the transmutation of high-level nuclear waste requires a number of challenging steps, such as the separation of individual radionuclides, the fabrication of targets on a large scale, and finally, their irradiation and disposal,” said Rodney C. Ewing, a professor in nuclear security and geological sciences at Stanford University. A radionuclide is an atom that has excess nuclear energy, making it unstable.
Excerpts from Zapping Nuclear Waste in Minutes Is Nobel Winner’s Holy Grail Quest, Bloomberg, Apr. 2, 2019
Twenty years and more than 12,380 shipments later, tons of Cold War-era waste from decades of bomb-making and nuclear research across the U.S. have been stashed in the salt caverns that make up the underground facility, the Waste Isolation Pilot Plant (WIPP) in New Mexico. Each week, several shipments of special boxes and barrels packed with lab coats, rubber gloves, tools and debris contaminated with plutonium and other radioactive elements are trucked to the site.
But the Waste Isolation Pilot Plant has not been without issues. A 2014 radiation leak forced an expensive, nearly three-year closure, delayed the federal government’s cleanup program and prompted policy changes at national laboratories and defense-related sites across the U.S. More recently, the U.S. Department of Energy said it would investigate reports that workers may have been exposed last year to hazardous chemicals.
Still, supporters consider the repository a success, saying it provides a viable option for dealing with a multibillion-dollar mess that stretches from a decommissioned nuclear weapons production site in Washington state to one of the nation’s top nuclear research labs, in Idaho, and locations as far east as South Carolina… Overall 22 sites around the nation that have been cleaned up as a result of having somewhere to put the waste — including Rocky Flats, a former nuclear weapons plant outside Denver that had a history of leaks, spills and other violations.
For critics, that success is checkered at best since the repository is far from fulfilling its mission. “It’s 80 percent through its lifetime, and it has disposed of less than 40 percent of the waste and has cost more than twice as much as it was supposed to,” said Don Hancock with the watchdog group Southwest Research and Information Center. “How great of a success is that?” Officials initially thought the facility would operate for about 25 years. Rather than wrapping up in the next few years, managers have bumped the timeline to 2050….
With some areas permanently sealed off due to contamination, more mining will have to be done to expand capacity. The federal government also is spending more than a half-billion dollars to install a new ventilation system, sink more shafts and make other upgrades aimed at returning to “normal business.”..,.
Toney Anaya, who served as New Mexico governor in the 1980s, remembers the heated debates about bringing more radioactive waste to the state. He said there were concerns about safety, but the promise of jobs was attractive. Some also argued New Mexico had a moral obligation given its legacy of uranium mining and its role in the development of the atomic bomb.

China will start building its first floating nuclear power plant in 2019. A floating nuclear power plant is a marine platform carrying a scaled-down or minuscule nuclear reactor to power islets and offshore drilling platforms that may otherwise have little or no access to the onshore grid supply. Analysts have associated these novel marine nuclear power stations with Beijing’s initiatives to militarize and “colonize” the South China Sea and turn its vast waters into a Chinese lake…
Mobile nuclear reactors could power the many man-made islands being created in the South China Sea, while transmitting electricity from the mainland would be expensive and conventional diesel generators could not meet the demand amid an expanding population of soldiers, constructors and residents….Observers say that as many as 20 floating nuclear stations could be needed across the South China Sea for new chunks of land created on reefs and shoals, especially in the Paracel and Spratly archipelagos that are subject to conflicting territorial claims by China and Vietnam, the Philippines, Malaysia and Taiwan. These reactors can also sail and power the many Chinese drilling platforms in the ocean to expedite the exploitation of oil, natural gas as well as “combustible ice,” a frozen mixture of water and concentrated natural gas found on the sea floor.

A proposal to take in more out-of-state waste at a West Texas radioactive waste disposal site has encountered an unlikely argument against it: that it can harm the booming oil and gas industry. Waste Control Specialists is asking state lawmakers for permission to take in more low-level radioactive waste — such as rags, syringes and protective clothing from nuclear plants or hospitals — from outside of Texas for disposal at its Andrews County facility near the Texas-New Mexico border.
Environmental groups have long opposed radioactive waste at the site, which they say could jeopardize groundwater. Environmentalists at the hearing were joined by Tommy Taylor, director of oil and gas development for Fasken Oil and Ranch, which operates in Andrews County. Quoting from a handbook of the International Atomic Energy Agency, Taylor said radioactive waste dumps should be sited away from “land with exportable minerals and energy resources.” “Don’t put it in an oilfield,” he said. “The oil and gas resources of the Permian Basin are too important for the security of the state of Texas and the United States to put it at risk with storing spent fuel rod casks in this region.”
Spent fuel is not designated as low-level waste, but he said he worried that designation could change. It’s unusual for a representative of an oil and gas company to publicly criticize at the Capitol another segment of the energy industry…
But If Waste Control Specialists becomes insolvent the state might have to take control of the facility. The legislation poposed by Texas lawmakers lifts the cap on the amount of out-of-state, low-level waste the company can accept at the 8.9 million cubic feet-capacity site from 30 percent to 60 percent. The company currently pays six Austin lobbyists as much as $240,000 to persuade lawmakers of the wisdom of its plans….Waste Control Specialists’ partnership with Orano USA, called Interim Storage Partners LLC, has asked the Nuclear Regulatory Commission for permission to accept used nuclear fuel — high-level waste — at the Andrews facility. Waste Control Specialists, which already disposes of other kinds of radioactive waste at its site in Andrews County, has been trying to position itself as a short-term alternative to Yucca Mountain, the Nevada site long ago selected by the federal government for storage of radioactive waste. Yucca had been bedeviled by decades of political quarrels, even as radioactive waste has piled up at the country’s nuclear power plants.

How do you make a 10,000-tonne container ship disappear? At Alang, a small town in Gujarat, on the western coast of India is the world’s biggest ship-breaking town. Almost a third of all retired vessels—at least 200 each year—are sent to be broken up here, at over 100 different yards stretching along 10km of sand. The industry employs some 20,000 people, almost all men who migrate from the poorer states of India’s northern Hindi-speaking belt. Taxes paid by breakers generate huge sums for the state government. Yet it is a dangerous industry for its workers and a filthy one in environmental terms.
Of 744 ships that were pulled apart worldwide last year, 518 were dismantled on beaches. Only 226 were processed “off the beach” at industrial sites designed for the purpose, according to the Shipbreaking Platform, an ngo which campaigns against beach-breaking. The majority of big shipping firms use beaches, except a tiny few such as Hapag Lloyd of Germany and Boskalis of the Netherlands.
A typical operation involves a ship being beached at low tide. Once her fittings and other resaleable parts are removed, hundreds of workers with gas blowtorches clamber over the vessel’s hull, cutting it into huge steel blocks. These are then dropped onto the beach, where they are cut up again before being sold, then rerolled for use in construction.
Apart from the danger of dropping tens of tonnes of steel from a great height, the method is immensely polluting. A review in 2015 by Litehauz, a Danish marine environmental consultancy, found that in the process of scrapping a 10,000-tonne ship at least 120 tonnes of steel becomes molten and is lost in the sea. Levels of mercury and lead, as well as oil, in Alang’s water are at least 100 times higher than at other beaches. Workers must handle asbestos and dangerous chemicals. Accidents are common. Last year 14 workers died at Alang.Alang is just one of many ship-breaking centres in South Asia. Among the others are beaches in Bangladesh (where workers reportedly include children) and Pakistan. Last year the subcontinent recycled around 90% of the world’s ships by tonnage.
Ship-breaking is concentrated in the region for three reasons. Prices for scrap steel are higher than elsewhere (90% of a ship is typically steel), thanks to demand for rerolled steel for construction. Labour costs are lower than at yards in Europe, America or Turkey (workers at Alang make up to 800 rupees, or $11, per day, and usually less) and safety and environmental regulations are much weaker. Most sellers scrap their ships in South Asia because they get better prices for them.
Shipowners, in particular Maersk, a Danish company which is the world’s biggest shipper, are preparing to comply with them…At the Baijnath Melaram shipyard a huge crane barge sits in the water next to a stretch of “impermeable” concrete. “We used to have to winch the blocks up the beach,” says Siddharth Jain, the firm’s business manager. Now, the crane lifts blocks of steel down from the ships directly to the concrete, so that they need never touch the sand. In contrast to the yards nearby, where men in simple work clothes and no safety goggles operate blowtorches, the workers scuttling around Baijnath Melaram wear boiler suits, face masks and helmets.
The changes are largely down to Maersk… Around 70 more are upgrading in order to meet standards set by the Hong Kong International Convention for the Safe and Environmentally Sound Recycling of Ships, an unratified treaty on ship recycling. Maersk’s campaign is in response to new regulations in force since December 31st 2018 that require all European-flagged vessels to be recycled at shipyards approved by Brussels. Just over a third of the world’s ships fall in this category. Maersk, whose fleet is roughly 40% European-flagged, hopes that the best yards at Alang will be able to comply with the new rules. Two Indian yards have already been audited for the European certification; 11 more have applied. “If we sustain that momentum, in five, six or seven years all of Alang could be really responsible,” says John Kornerup Bang, Maersk’s sustainability chief.
But on January 30, 2019 the eu announced that the Indian yards audited will not make the list,… Ingvild Jenssen of the Shipbreaking Platform says that even Alang’s best yards are not clean enough. She argues that Maersk’s efforts merely “greenwash” a model that needs to change completely…. Not clean enough for Europe; but too expensive to compete with breakers in Bangladesh or Pakistan which have not changed at all. If that happens, the industry in Alang—and the jobs and revenue it generates—could disappear almost as quickly as the ships it dismantles.
Excerpt from HIgh by the Beach: Ship Recycling, Economist, Mar. 9, 2019
The hard surface of waterborne plastic provides an ideal environment for the formation of biofilm by opportunistic microbial colonisers, and could facilitate a novel means of dispersal for microorganisms across coastal and marine environments. Biofilms that colonise the so-called ‘plastisphere’ could also be a reservoir for faecal indicator organisms (FIOs), such as Escherichia coli, or pathogenic bacteria such as species of Vibrio.
A study published in March 2019 looks into five public bathing beaches and quantifies their colonisation by E. coli and Vibrio spp. Nurdles [i.e., microplastics] were heterogeneously distributed along the high tide mark at all five beaches, and each beach contained nurdles that were colonised by E. coli and Vibrio spp. Knowledge of E. coli colonisation and persistence on nurdles should now be used to inform coastal managers about the additional risks associated with plastic debris.
Status of Cleaning up Oil Pollution in Ogoniland, Nigeria:
According to the Civil Society Legislative Advocacy Centre (CISLAC), the clean-up of Ogoniland is bugged with identity crisis, procedures, processes and overheads. Perception of corruption, lack of transparency and accountability, complex decision making, internal crisis of choice between Ogoni and the Niger Delta….The United Nations Environment Programme (UNEP) released its Environmental Assessment of Ogoniland in August 2011 after series of protests of oil spillage in the community that culminated to the death of Ken Sarowiwa and eight others. The report made recommendations to the government, the oil and gas industry and communities to begin a comprehensive cleanup of Ogoniland, restore polluted environments and put an end to all forms of ongoing oil contamination in the region…
Pollution of soil by petroleum hydrocarbons in Ogoniland is extensive in land areas, sediments and swampland. In 49 cases, UNEP observed hydrocarbons in soil at depths of at least 5 metres. At 41 sites, the hydrocarbon pollution has reached the groundwater at levels in excess of the Nigerian standards permitted by National Laws..

Finland’s Radiation and Nuclear Safety Authority (Stuk) yesterday informed the government it sees no reason why an operating licence for the first-of-a-kind nuclear plant EPR at Olkiluoto 3 should not be granted to utility Teollisuuden Voima Oyj (TVO).]…The Areva-Siemens consortium began construction of Olkiluoto 3 – the first-of-a-kind EPR – in 2005 under a turnkey contract signed with TVO in late 2003. Completion of the reactor was originally scheduled for 2009, but the project has suffered various delays and setbacks. Under the latest schedule, fuel will now be loaded into the reactor core in June 2019, with grid connection to take place in October 2019, and the start of regular electricity generation scheduled for January 2020.
In December 2018, unit 1 of the Taishan plant in China’s Guangdong province became the first EPR to enter commercial operation. Taishan 2 is scheduled to begin commercial operation in 2019. The loading of fuel into the core of the Flamanville EPR in France is expected towards the end of this year. Two EPR units are also under construction at the Hinkley Point C project in Somerset, UK.

A portion of DOE’s technology development should focus on breakthrough solutions and technologies that can substantially reduce schedules, risks, and uncertainties in the cleanup, says Independent Assessment of Science and Technology for the Department of Energy’s Defense Environmental Cleanup Program. This effort should be managed by ARPA-E, a DOE division that has a record of investing in innovative solutions for complex technical challenges; it would require substantial new funding…DOE’s Office of Environmental Management (DOE-EM) is responsible for cleaning up 107 sites in 31 states and one territory that were used for nuclear weapons development, testing, and related activities during the Manhattan Project and Cold War. The cleanup program began in 1989 and has, over the past three decades, cleaned up 91 sites at a cost of about $170 billion. DOE-EM projects that it will spend at least another 50 years and $377 billion to complete its cleanup of the 16 remaining sites.
The new report says that these time and cost estimates are highly uncertain – and probably low – because of significant remaining technical challenges and uncertainties, and also because additional sites and facilities may be added to the cleanup program in the future. ..Currently, DOE-EM’s management of S&T development is ad hoc and uncoordinated, the report says. Most DOE-EM-related S&T development activities are focused on individual sites, are driven and managed by contractors, and have a short-term emphasis on addressing technical challenges in existing cleanup projects…The successful cleanup of the large, complex Rocky Flats site near Denver showed that technology development and deployment can have major impacts in accelerating schedules and reducing costs, the report notes. The remaining cleanup sites – which include large, complex sites such as Hanford in Washington state, the Savannah River Site in South Carolina, and the Oak Ridge Reservation in Tennessee – provide an opportunity for S&T to have similar impacts.
The report identifies seven examples of technologies and alternative approaches that could substantially reduce costs and speed cleanup schedules – these include changes in waste chemistry and nuclear properties to facilitate treatment and disposal, and changes in human involvement in cleanup activities to increase efficiencies and reduce worker risks.
Excerpts from Breakthrough Solutions and Technologies Needed to Speed Cleanup of U.S. Nuclear Weapons Sites, National Academies Press Release, Mar. 4, 2019
In January 2019, the Defense Department issued a call for information in support of the aptly titled Project Dilithium. It seeks to develop a tiny, readily transportable, yet virtually indestructible nuclear power reactor for use at forward operating bases, the military facilities that provide logistical and troop support to the front-lines of conflict zones.
To be sure, the type of reactor it is seeking could be a great military asset: all the benefits of nuclear energy with none of the risks. The costly and dangerous process of trucking diesel fuel to bases, sometimes through hostile territory, may eventually be a thing of the past. Unfortunately, the need to store and ship irradiated nuclear fuel in a war zone will introduce different problems. And the odds that a meltdown-proof reactor could be successfully developed any time soon are vanishingly small.
The Defense Department…is seeking a nuclear reactor capable of producing 1 to 10 megawatts of electricity. …The reactor, at a minimum, should be less than 40 tons total weight; small enough to be transported by truck, ship, and aircraft; able to run for at least three years without refueling; and capable of semi-autonomous operation… The reactor should have an “inherently safe design” that ensures “a meltdown is physically impossible in various complete failure scenarios;” cause “no net increase in risk to public safety … by contamination with breach of primary core;” and have “minimized consequences to nearby personnel in case of adversary attack.
An Octrober 2018 report commissioned by the army’s Deputy Chief of Staff admits, quite reasonably, that exposed mobile nuclear plants would “not be expected to survive a direct kinetic attack.” If commanders need to expend significant resources to protect the reactors or their support systems from military strikes, such reactors could become burdens rather than assets. Can one really invent a reactor robust enough to suffer such a strike without causing unacceptable consequences? …If a severe accident or sabotage attack were to induce more extreme conditions than the reactor was designed to withstand, all bets are off. How long would passive airflow keep nuclear fuel safely cool if, say, an adversary threw an insulating blanket over a small reactor? Or if the reactor were buried under a pile of debris?
Moreover, it is hard to imagine that a direct explosive breach of the reactor core would not result in dispersal of some radioactive contamination. An operating nuclear reactor is essentially a can filled with concentrated radioactive material, including some highly volatile radionuclides, under conditions of high pressure and/or temperature. Even a reactor as small as 1 megawatt-electric would contain a large quantity of highly radioactive, long-lived isotopes such as cesium-137—a potential dirty bomb far bigger than the medical radiation sources that have caused much concern among security experts.
At best a release of radioactivity would be a costly disruption, and at worst it would cause immediate harm to personnel, render the base unusable for years, and alienate the host country. For any reactor and fuel design, extensive experimental and analytical work would be needed to understand how much radioactivity could actually escape after an attack and how far it would disperse. This is also true for spent fuel being stored or transported.
The 2018 report describes several existing reactor concepts that it thinks might meet its needs. One is the 2 megawatt-electric “Megapower” reactor being designed by Los Alamos National Laboratory. But a 2017 INL study of the design identified several major safety concerns, including vulnerabilities to seismic and flooding events. The study also found that the reactor lacked sufficient barriers to prevent fission product release in an accident. INL quickly developed two variants of the original Los Alamos design, but a subsequent review found that those shared many of the safety flaws of the original and introduced some new ones.
The other designs are high-temperature gas-cooled reactors that use TRISO (“tristructural isotropic”) fuel, which was originally developed decades ago for use in reactors such as the now-decommissioned Fort St. Vrain plant in Colorado. TRISO fuel consists of small particles of uranium coated with layers of different materials designed to retain most fission products at temperatures up to 1,600 degrees Celsius.
TRISO fuel enthusiasts have long claimed that reactors utilizing it do not need containments because each particle essentially has its own. This would seem to make TRISO an ideal fuel for small, mobile reactors, which can’t be equipped with the large, leak-tight containment structures typical of commercial power reactors. The army report buys into the notion that these “encapsulated” nuclear fuels can “avoid the release of radioactive volatile elements” and prevent contamination of the surrounding area, either during normal operations or accidents.
TRISO fuel’s actual performance has been inconsistent, however, and much is still not known. The Energy Department has been carrying out a program for more than a decade to try to improve TRISO fuel, but final results are not expected for years. In addition, if the fuel temperature rises above 1,600 degrees Celsius, fission product release can rapidly increase, making it vulnerable to incendiary weapons that burn hotter, such as thermite. The Defense Department may have already realized that TRISO fuel is not as miraculous as it first thought.
The RFI also specifies that the reactor should be capable of being transported within seven days after shutdown, presumably with the irradiated nuclear fuel still inside. While this requirement is understandable—if forces need to retreat in a hurry, they would not want to leave the reactor behind—it is unrealistic to expect this could be met while ensuring safety. Typically, spent nuclear fuel is stored for many months to years after discharge from a reactor before regulators allow it to be shipped, to allow for both thermal cooling and decay of short-lived, intensely radioactive fission products. Moving a reactor and its irradiated fuel so soon after shutdown could be a risky business.
Finally, the proliferation risks of these reactors and their fuel is a concern. The original RFI stipulated that the reactor fuel had to be high-assay low-enriched uranium (HALEU), which is uranium enriched to levels above the 5 percent uranium-235 concentration of conventional power reactors, but still below the 20 percent that marks the lower limit for highly enriched uranium (HEU), which is usable in nuclear weapons….If the Defense Department goes forward with Project Dilithium, other nations, including US adversaries, may be prompted to start producing HALEU and building their own military power reactors.

Nine nationst control the roughly 14,200 nuclear weapons in the world… But What makes a good nuclear arsenal? First, a good nuclear doctrine. Will a country strike first, or only in response? Second, safety. Are the nukes secure? Does the country participate in nonproliferation treaties? Third, do the nukes work as intended? Is the arsenal sufficient? Can the nukes survive an initial attack?…Business Insider has weighed these questions with the help of Hans Kristensen, the director of the Nuclear Information Project at the Federation of American Scientists, to rank the world’s nuclear arsenals.
9. North Korea: North Korea fails by virtually every metric used to measure nuclear arsenals… Because Pyongyang can never hope to defeat any of its enemies in conventional fighting, it turned to nukes as a guarantor of its security. Weapons count: estimated 60. North Korea has a number of short- to intercontinental-range ballistic-missile systems thought to operate off the backs of mobile missile launchers. One analyst has warned that North Korea’s mobile launchers may simply distract from the real threat of hidden nuclear silos, but no evidence of such silos has ever appeared in US intelligence reports made public. It’s completely unknown if North Korea keeps its nuclear weapons mated or with the warhead affixed to the missile.
8. Pakistan: Pakistan built nuclear weapons in response to its bitter regional rival, India, testing and proceeding with a relatively simple nuclear mission: deter or defeat India….Pakistan has links to Islamic extremists with connections to global terror networks. Experts have long feared not enough has been done to secure Islamabad’s nukes against these threats. Additionally, “Pakistan has lowered the threshold for nuclear weapons use,” by building smaller, tactical nuclear weapons. Weapons count: 150. Pakistan has ballistic missiles with ranges just long enough to hit anywhere in the country of India….The US has specifically given Pakistan permission to modify its F-16 fighters to drop nuclear weapons…Pakistan is thought to keep its nuclear warheads separate from its missiles and delivery systems.
7. India: “India is still a nuclear posture that’s still in vivid development,” Just as Pakistan fears India’s greater strength and numbers, India has come to fear China’s growing and modernizing conventional forces. But unlike Pakistan, India has sworn off nuclear first strikes and not looked into tactical nuclear weapons. ..But India’s submarine fleet remains a dream at the moment, lowering its overall score. Weapons count: 140 (stored) India recently launched its first nuclear-powered submarine..As it stands, the missiles and submarine India has picked out for its underwater nuclear deterrent can’t range China’s vital points or most of Pakistan.
6. Russia: “Russia seems to sort of be driven by a frantic exploitation of different options,” Weapons count: 6,850 (1,600 deployed; 2,750 stored; 2,500 retired). Russia has the full nuclear triad with constantly modernized bombers, land-based missiles, and submarines. The triad is a true 24/7/365 force with submarines on deterrence patrols at all times. Additionally, Russia has a high number of tactical nuclear weapons with shorter-range and smaller-explosive yield…Russia’s Poseidon underwater 100 to 200 megaton nuclear torpedo is the biggest nuclear explosive device ever built…The weapon would essentially set off tidal waves so large and an explosion so radioactive and punishing that continents, not countries, would pay the price for decades. The US has not found it useful to respond to these doomsday-type devices. Russia stores its nuclear warheads mated to missiles and ready to fire. Additionally, it has surrounded Moscow with 68 nuclear-tipped missile interceptors meant to protect the city from a US strike.
5. Israel: “Israel is interesting because it’s a semi-dormant nuclear program, but it’s not dormant,” …Israel’s conventional military, with its top-of-the-line air force and close coordination with the US, easily overpowers its regional foes in traditional fighting. Instead of reaching for nuclear weapons to threaten a more powerful foe, Israel has a “very relaxed nuclear posture, truly what you could call a last resort posture,” Weapons count: estimated 80..Truly, nobody knows what weapons Israel has or doesn’t have, and that’s the way they like it.
4. UK: Weapons count: 215 (120 deployed; 95 stored) During the Cold War, the UK labored to create its own nuclear weapons and delivery systems, but since the collapse of the Soviet Union, the UK has withdrawn from that posture and essentially become a client of the US. The UK operates four nuclear submarines that fire can fire 16 Trident missiles made by the US. That’s it. The UK won’t get an “arsenal” page for this reason. The warheads on these patrols are mated to missiles.
3. France: France has a long history with nuclear weapons, like the UK, but has maintained more independence and control over its stockpile and doctrine. Weapons count: 300 (290 deployed; 10 stored)..France has four nuclear-powered submarines, one of which stays on a constant deterrence patrol ready to fire mated nuclear missiles. While it’s not a nuclear weapon outright, outside of the US, only France operates a nuclear-powered aircraft carrier, the Charles de Gaulle.
2. US: Weapons count: 6,450 (1,750 deployed; 2,050 stored; 2,650 retiredd)Today the US’s nuclear arsenal has narrowed down to a triad in constant stages of modernization. The US operates two nuclear-capable bombers, the B-2 Spirit stealth bomber and the B-52 Stratofortress, originally built in the 1950s and slated to fly for 100 years. The US operates a fleet of nuclear submarines, which it keeps on constant deterrence patrols. The US also has nearly 400 intercontinental-range missiles in silos around the country, mostly aimed at Russia’s nuclear weapons for an imagined “mutual destruction” scenario. Recently, the US has come under intense criticism for President Donald Trump’s proposal to build more smaller or tactical nuclear weapons. Experts say these weapons make nuclear war more likely. The US has tactical nuclear weapons stored around Europe and Turkey, which, like the bigger strategic weapons, are stored mated.
1. China: China has just 280 nuclear warheads, and none of them are mated to delivery systems. China flies bombers and sails submarines that it calls nuclear-capable, but none of them have ever actually flown with nuclear weapons. China’s nuclear doctrine forbids first strikes and centers around the idea that China would survive a nuclear strike, dig its bombs out of deep underground storage, and send a salvo of missiles back in days, months, or years. This essentially nails the idea of “credible minimum deterrence.” Everyone knows China has nuclear weapons, that they work, and nobody doubts China would use them if it first received a nuclear attack. China has nuclear-capable submarines and bombers, but they do not ever travel with nuclear weapons on board. China relies on a growing and modernizing conventional military to assert its will on other countries and virtually never mentions its nuclear arsenal.

A Greenpeace report details how plans to discharge over 1 million tonnes of highly contaminated water into the Pacific Ocean was proposed by a Japanese government task force. According to Greenpeace.
“The decision not to develop water processing technology that could remove radioactive tritium was motivated by short term cost cutting not protection of the Pacific ocean environment or the health and livelihoods of communities along the Fukushima coast,” said Kazue Suzuki, Energy Campaigner at Greenpeace Japan. “ The report concludes that the water crisis remains unresolved, and will be for the foreseeable future. The only viable option to protect the environment and the communities along the Fukushima coast being long term storage for the contaminated water.
The discharge option for water containing high levels of radioactive tritium was recommended as least cost by the Government’s Tritiated Water Task Force and promoted by Japan’s Nuclear Regulation Authority (NRA). The Task Force concluded in 2016 that “sea discharge would cost 3.4 billion yen (US$30 million) and take seven years and four months to complete. It concluded that this was cheapest and quickest of the five methods.” However, technical proposals for removing tritium were submitted to the same Government Task Force by multiple nuclear companies with estimated costs ranging from US$2-US$20 billion to US$50-US$180 billion depending on the technology used. These were dismissed as not viable but without detailed technical consideration.
TEPCO has claimed since 2013 that its ALPS technology would reduce radioactivity levels “to lower than the permissible level for discharge.” However, in September 2018 TEPCO admitted that the processing of over 800,000 tons of contaminated water in 1000 storage tanks, including strontium, had failed to remove radioactivity to below regulatory limits, including for strontium-90, a bone seeking radionuclide that causes cancer. TEPCO knew of the failure of the technology from 2013. The Greenpeace report details technical problems with the ALPS system.
The Fukushima Daiichi site, due its location, is subject to massive groundwater contamination which TEPCO has also failed to stop. Each week an additional 2-4000 tonnes of contaminated water is added to the storage tanks.

Worried the U.S. may be falling behind rivals in nuclear-power technology, the Energy Department plans to spend $115 million to help develop advanced fuels for next-generation reactors. Under a three-year pilot project announced, the money would go to an Ohio company to produce a more energy-dense uranium, which the nuclear industry has been asking for to support a budding industry of smaller reactors. Department officials say they plan to award the contract to American Centrifuge Operating, a unit of Centrus Energy Corp. , unless rival companies can make a compelling case by Jan. 22, 2019.
The U.S. nuclear industry is at a crossroads that has jeopardized its workforce in the U.S. and helped fuel the rise of U.S. rivals abroad. The industry, faced with safety concerns, expensive regulations and competition from other fuels, is pushing to reinvent its core technology to be simpler, cheaper and often much smaller….China has become one of the few countries building nuclear-power capacity, and Russia has taken a dominant position in developing projects elsewhere…Russia is the only country capable of producing the higher-enriched uranium the Energy Department’s new program would produce. Without it, the U.S. risks being left out of the global industry’s next stage, said Dan Brouillette, Deputy Energy Secretary.

At least 1.9 trillion yen ($17.12 billion) will be needed for the planned scrapping of 79 nuclear facilities, including the failed Monju prototype fast-breeder reactor, according to the Japan Atomic Energy Agency (JAEA).
However, the JAEA’s estimate, released on Dec. 26, 2018 does not include maintenance expenses for the facilities nor costs to deal with leftover uranium and plutonium, meaning the actual tally could increase by hundreds of billions of yen. State subsidies account for the bulk of the JAEA’s budget, so taxpayers will likely foot most of the bill. The agency plans to shut down 79 of its 89 nuclear facilities, including research reactors and test buildings, over 60 to 70 years due to aging and the huge costs needed for their continued operations under stricter safety standards.
According to the JAEA’s estimate, the cost to decommission the Tokai spent nuclear fuel reprocessing plant in Ibaraki Prefecture will be 770 billion yen. But the overall cost would reach nearly 1 trillion yen if expenses on dealing with highly radioactive liquid waste, which is left after plutonium is extracted from spent fuel rods at the plant, are included.
The problem-plagued Monju prototype fast-breeder reactor in Tsuruga, Fukui Prefecture, cost taxpayers more than 1 trillion yen ($8.82 billion) despite running for only 250 days during its two-decade operation. ..But the JAEA currently has no plan on how to handle plutonium stored at the facilities. In addition, no decision has been made on what to do with radioactive waste from the 79 facilities that could fill more than 560,000 200-liter drums.

THE ASAHI SHIMBUN, Dec. 27 2018
Making shipping cleaner is made more urgent by the decision of the International Maritime Organisation (IMO), the United Nations body responsible for the world’s shipping, to reduce the amount of sulphur allowed in bunker fuel from 3.5% to 0.5% by 2020. Sulphur is nasty stuff. When burned, it forms sulphates, which cause acid rain and pollute the air. A paper published in February 2017 in Nature Communications, by Mikhail Sofiev of the Finnish Meteorological Institute, found that the imo’s new rule could stop between 139,000 and 396,000 premature deaths a year.
The trouble is that sulphates also scatter sunlight and help to form and thicken clouds, which reflect solar radiation away from Earth. As a result, shipping is thought to reduce rather than increase man-made global warming—by 7% throughout the 20th century, according to one study. Dr Sofiev’s research showed that this cooling effect could fall by 80% after 2020, with the new low-sulphur standard in place…
The obvious way to offset the loss of sulphur-related cooling is by steep cuts to shipping’s planet-cooking carbon-dioxide emissions. The IMO wants these to fall by half, compared with 2008 levels, by 2050, regardless of how many vessels then ply the seas. But unlike desulphurisation, which is both imminent and legally binding, the CO2 target looks fuzzy and lacks any enforcement mechanism. An attempt to begin fleshing it out, at a meeting of IMO member states which concluded in London on October 26, 2018 foundered.
One way to cut fuel consumption is to reduce drag by redesigning hulls and propellers. This is happening. In the past five or so years many ships’ propellers have been fitted with tip fins analogous to the turbulence-reducing upturned winglets on aeroplanes. Further percentage points can be shaved away by smoothing hulls. This means, in particular, stopping barnacles and other creatures growing on them. Tin-based antifouling paints are now banned as toxic to sea life, so paintmakers are returning to an 18th-century solution to the fouling problem—copper. Hulls can be scraped smooth, too, but restrictions on littering waters with paint chips and species from foreign parts have made such cleaning problematic. This may change, though, thanks to an underwater drone described by its Norwegian maker, ecosubsea, as “a cross between a vacuum cleaner and a lawnmower”. Rather than scour hulls with a metal brush, ecosubsea’s robots blast water at an angle almost parallel with the hull’s surface, which mostly spares paint from abrasion but hits marine growth perpendicularly, and thus hard.
Many have hopes of returning to wind propulsion, and engineers have devised various modern versions of the sail. None has yet succeeded. A system developed by SkySails, a firm in Hamburg, for example, relied on kites to pull ships along. It was installed on five ships from 2008-11, but proved fiddly to use and maintain…
Some hope to cut marine emissions by employing batteries and electric motors. For transoceanic shipping this looks a long-shot. But local shipping might benefit. Norway, for instance, has started to introduce battery-powered ferries. And a Dutch company called Port-Liner is building electric canal barges for transporting shipping containers. The technology is expensive. Without taxpayer subsidy it would hardly be a runner—a fact also true of the Norwegian ferries.
The problem of shifting emissions around rather than eliminating them also applies to the idea of powering ocean-going vessels using fuel-cells. These generate electricity by reacting hydrogen and oxygen together. Given that electric propulsion more usually disguises emissions than eliminates them, some suggest the most practical approach to reducing shipping’s contribution to global warming is to switch to low-carbon fuel systems rather than conducting a futile search for no-carbon fuels. One alternative is diesel-electric propulsion. Liquefied natural gas (lng) is another option.

After spending billions of dollars over several decades to remove radioactive waste leaking from a plant where nuclear bombs were made, the U.S. Department of Energy has come up with a new plan: leave it in the ground. The shuttered Hanford Nuclear Reservation, which produced plutonium for U.S. atomic weapons from World War II through the Cold War, is the nation’s largest nuclear cleanup site with about 56 million gallons of waste stored in leak-prone underground tanks in south-central Washington State. The Energy Department has proposed to effectively reclassify the sludge left in 16 nearly empty underground tanks from “high-level” to “low-level” radioactive waste. The re-classification would allow the department to fill the tanks with grout, cover them with an unspecified “surface barrier,” and leave them in place.
But environmental groups and others say the plan amounts to a semantic sleight of hand that will leave as much as 70,000 gallons of remaining nuclear sludge — some of which could be radioactive for millions of years — in the ground…
The cleanup operations at Hanford are projected to cost more than $100 billion, and the Energy Department has already spent more than $19 billion, according to the Government Accountability Office. The reclassification could save the department billions of dollars. It would also open the door to doing the same for all 177 tanks on the sprawling 586-square-mile reservation.
The Columbia River borders the Hanford land for almost 50 miles and some of the tanks are as close as five miles (eight kilometers) to the river, the largest in the Pacific Northwest and the source of irrigation for agriculture and drinking water for downstream citiesions.
Opponents include the Yakama Nation, whose reservation is located 20 miles west of the Hanford site and that has treaty rights to the Chinook salmon that spawn in the Columbia River. The nation wrote in comments to the agency that leaving the waste in unstable shallow land is “simply bad policy.”

The broad coalition of labor unions, state public service commissioners, clean energy organizations, and energy trade associations told U.S. House and Senate leaders in a December 4, 2018 letter: “It is time for the federal government to meet its statutory and contractual obligations. Utilities and their electricity customers have done their part.”
The letter notes that the Nuclear Waste Fund—a U.S. Treasury account collected via a fee charged to electric ratepayers over 30 years—today holds a balance of more than $40 billion. The fund is mostly unused, owing to paralysis of the Yucca Mountain project, and it continues to accumulate interest of about $1.7 billion a year from investments in Treasury securities.
About $7.4 billion in damages have now also been paid out from the Treasury’s Judgment Fund to utilities, which have filed lawsuits against the Department of Energy (DOE) since 2000, seeking compensation for defaulting on a standard contract and missing the deadline to begin disposing of highly radioactive spent nuclear fuel as required by the Nuclear Waste Policy Act of 1982. To date, 40 suits have been settled and an additional 57 cases have been resolved, a November 2018 special report from the DOE’s Office of Inspector General noted.
The coalition includes major industry trade groups the Nuclear Energy Institute (NEI), the American Public Power Association, the National Rural Electric Cooperative Association, and the Edison Electric Institute—along with the National Association of Regulatory Utility Commissioners, which is a group of state regulators….According to the NEI, the inventory of used fuel in temporary storage at 75 reactor sites scattered across 33 states has now grown to more than 80,000 metric tons.

Robots have been used in nuclear facilities for a long time.Scenarios such as maintenance tasks in nuclear facilities or even disasters like radioactive leaks or search and rescue operations have proven to be quite successful. We are talking about robotic arms or remote operated vehicles with some end effectors built in to handle dangerous situations.”
1986: Chernobyl’s robot trouble–During the Chernobyl nuclear incident, the Soviet authorities in charge of cleaning up nuclear waste developed around 60 unique remote-controlled robots to spare human workers from radioactive exposure. The total cost of the clean-up operation was $2bn. Designs included the STR-1 robot, which resembles a moon buggy. It was placed on the roof of the nuclear plant and used to clean upparts of the destroyed reactor. Another design for the purpose of debris cleaning was the Mobot, developed by Moscow State University. It was a smaller version of a loader used in construction, with a front-end bucket used to scoop up debris.
The problem was that cleaning up nuclear waste required more skills than the robots could provide, eventually resulting in the authorities sending in soldiers to perform most of the decontamination works. Radiation was so high that each worker could only spend 40 seconds inside or near the facility; 31 died from exposure, while 237 suffered from acute radiation sickness.
2008: Cleaning up nuclear waste at Hanford Nuclear Reservation. The Hanford Nuclear Reservation in the US has been somewhat of a hub for nuclear waste innovation. This is because scientists, and their robot friends, are faced with the task of emptying nuclear and chemical waste tanks the size of around 150 basketball courts
