Forget Nevada! How America Buries its Nuclear Waste 1999-2019

Just before midnight on June 27, 2019, the Waste Isolation Pilot Plant (WIPP), Carlsbad, New Mexico received its 12,500th transuranic (TRU) waste shipment since operations began there in 1999.

Nuclear Waste heading to WIPP from Idaho

The shipment originated from the EM program at Idaho National Laboratory, which has sent WIPP the most TRU waste shipments — 6,500 and counting — of all Departement of Energy (DOE) generator sites over the past 20 years…

How to Clean a Multibillion-Dollar Radioactive Mess: WIPP

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.

Nuclear Waste Disposal in Canada

Critics of Ontario Power Generation’s plan to build an underground nuclear waste dump on the shores of Lake Huron have always considered it absurd.…The fiercely debated plan to build what is called a Deep Geological Repository (DGR) has been going on for 14 years. In addition to Michigan lawmakers, more than 150,000 people have signed petitions, and 187 communities representing 22 million people have passed resolutions opposing the plan.

What has been in the works for decades is the construction of an underground permanent burial facility for all of Ontario’s low- and intermediate-level radioactive waste at the Bruce Nuclear Generating Station in Kincardine, Ontario.  That’s less than a mile inland from the shores of Lake Huron and about 440 yards below the lake level. Kincardine, a small community about 114 miles upstream from Port Huron agreed to have the facility in their town but will be financially compensated.  If and when the DGR is in place, an estimated 52 million tons of nuclear waste will be shipped to the site from other nuclear plants around Canada. Some of those discarded materials will remain toxic for more than 100,000 years as they are stored in limestone caverns. Once full, the shafts are to be sealed with sand, clay and concrete.

OPG has assured the residents and the public, “Years of scientific research have shown that the geology under the Bruce nuclear site is ideal for a DGR; it is some of the tightest rock in the world, impermeable limestone that has remained intact through 450 million years, multiple ice ages and glaciers.”  However great limestone might be to say it can hold up to nuclear waste seems presumptuous considering the current reputation of the world’s other DGRs.“There are only three deep nuclear waste dumps on our entire planet to have held nuclear waste,” Fernandez said. “They have all failed and leaked.”The three sites include the Waste Isolation Pilot Project (WIPP) in New Mexico and two German sites, Asse II and Morslenben, both former salt mines.

The WIPP nuclear waste dump was supposed to contain its deadly waste for 10,000 years. Despite scientific assurance to the contrary, a mere 15 years into WIPP’s operational phase, a container exploded, spewing its deadly contents up to the surface, contaminating 22 workers and traveling into the biosphere and down to the next town, said Fernandez.

As part of an environmental assessment of the plan, a panel appointed by the federal government heard testimony by individuals and experts on both sides of the debate. Among the speakers to present evidence (in a well-documented report) that OPG was misleading the public including what they planned to store in the facility was Dr. Frank Greening. His report was thought to put an end to the plan.  Greening is a scientist, who worked for more than 20 years in the nuclear division of OPG. He was one of their most senior men, a chemist in charge of overseeing the degradation of structural materials, especially the crucially important pipes in the primary cooling systems of CANDU reactors.

Greening submitted a report disclosing important factors that OPG failed to share among them being the radioactive inventory for the proposed repository. Using words like dirty rags and mops, which is how they described some of the waste to be stored, does not sound as alarming as old reactors or ion exchange resins that bear a significant amount of Carbon-14, a radionuclide that has a half-life of more than 5,700 years.  “They’ve done a very sloppy job in looking at the hazards of the waste. You cannot just look at the radioactive properties but also its chemical properties,” Greening said. The chemical properties of the waste can lead to fires and explosions underground, which as critics fear, could cause a leak.

Building the DGR also requires a mining company to dynamite the rock formations. What about the potential risk to the nuclear plant itself, during construction of the DGR?  “I could go on and on about the scenarios and this is what they’re not talking about,” Greening said.

Another point of concern that Greening feels everyone is overlooking is OPG’s degraded safety culture and its lackadaisical response to concerns about unforeseen accidents. As an example of its history, Greening cited several incidents at OPG that allowed workers (many of them local tradesmen) to be exposed to radioactive materials including plutonium dust.

But I believe one should always look for the least risky solution and that would be to build it inland, in the Canadian Shield (granite), in Manitoba, like they originally planned to do in the 1980s.”

Kitty Litter and Nuclear Waste: Don’t Mix

The US energy department is to fund $73m in road and other infrastructure projects in New Mexico as compensation for radiation leaks at a nuclear laboratory and underground dump.The deal struck between the department and New Mexico forgoes fines and instead applies funds to upgrade federal nuclear facilities and surrounding communities in the state, according to settlement documents.  Projects include construction of a $5m emergency operations centre in Carlsbad, near where the nuclear waste dump leaked radiation in February 2014.

The leak at the Waste Isolation Pilot Plant, or Wipp, exposed 22 workers to radiation in amounts not expected to threaten their health and led to the indefinite suspension of key operations at the site, which is the energy department’s only permanent underground disposal facility for certain types of waste from US nuclear labs.The radiation accident was caused by “chemically incompatible” contents, including cat litter, which reacted in a barrel of waste and caused it to rupture, according to a federal probe of the mishap.  The breached drum containing radioisotopes such as plutonium was improperly packaged with the wrong sort of absorbent litter at the Los Alamos National Laboratory near Santa Fe before it arrived at WIPP for disposal, investigators found….

The deal includes $34m to improve roads around the Wipp site, $12m to improve nuclear waste transportation routes in and around Los Alamos, and $9.5m in stormwater management upgrades at the lab’s complex.In addition it provides $10m for improvements to water infrastructure in and around Los Alamos and $2.75m for an independent compliance and operational review. Energy department officials have estimated the cost of the initial recovery of the dump at $240m and that it might be two years or more before it is fully operational.
