The Nine and their Nuclear Weapons

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 weaponsWeapons 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 Never-Ending Disaster: radioactive water at Fukushima

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.

Keeping up with the Joneses: Nuclear Power

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.

What to Do with 56 000 Drums of Nuclear Waste: Japan

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.

Cleaning Up Dirty Shipping

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.

The Underground Nuclear Tank Farms: Hanford

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.”

Scattered Nuclear Waste: 88 000MT, 33 States, 75 Plants

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.
