Coronavirus affecting France’s nuclear reactors’ safety and output

Montel News 14th May 2020, The overhaul of the schedule for shutdowns of EDF nuclear reactors during the Covid-19 pandemic will “considerably” reduce the safety margins of French power plants and will probably lead to further delays, experts told Montel. The nuclear agency is now under “potentially devastating pressure,” said Mycle Schneider, an independent energy consultant based in Paris and a critic of the nuclear industry.
The impact of the coronavirus adds to the equipment and maintenance problems that have accumulated in recent years and forced the company to reduce its nuclear production. “This is one
problem that overlaps with another. This is what is so worrisome, the accumulation of difficult events and circumstances, “he said.
Monday, EDF announced the postponement of 30 outages planned until 2022, explaining
that it postponed maintenance to secure the electricity supply for the winter. Already last week, the company had extended shutdowns of more than 40 reactors.https://www.montelnews.com/fr/story/la-pression-sur-edf-fait-craindre-pour-la-sret-nuclaire/1114

Radiation leak at nuclear research reactor

Germany: Radiation leak detected at research reactor, DW, 17 May 20, 

A research reactor near Munich has emitted excess C-14 radiation, says the Bavarian city’s technical university. The “slight” leak late March had shown up Thursday when monthly readings were collated.

Munich’s technical university (TUM) said Saturday a neutron reactor located at Garchingjust north of the metropole was found to have leaked nuclides into the atmosphere “slightly” above the level permitted annually in its license.

Neither human beings nor the surrounding environment had been endangered, said the TUM and Bavaria’s environmental ministry — responsible for oversight.

Monthly figures collated on Thursday had shown an excess in C-14 particles 15% above the permitted yearly level, with the potential to cause “theoretically” a load for the public of 3 Mikrosieverts at the maximum…….

The facility was put on hold on March 17 because of the current pandemic, leaving many scientists unable to glean results for industry and medicine, said Görg.

The FRMII reactor, inaugurated in 2005, remains controversial among organizations like Germany’s branch of Friends of the Earth (BUND) and opposition Greens in Bavaria’s state assembly…….   https://www.dw.com/en/germany-radiation-leak-detected-at-research-reactor/a-53467330

South Carolina nuclear fuel plant treatment pool leaking, polluting groundwater?

Radioactive muck found in pond; liner may be leaking at SC nuclear fuel plant, The State BY SAMMY FRETWELL, MAY 13, 2020  Nearly 40 years ago, the operators of a nuclear fuel plant near Columbia installed a liner in a treatment lagoon, hoping to trap radioactive and chemical waste before it could trickle into groundwater beneath the pond.

Now, the lagoon liner is wearing out. And that’s a concern.

Recent research suggests radioactive pollution has seeped through the synthetic barrier that was supposed to protect soil and groundwater in the Congaree River flood plain. Soil below the liner is suspected of being polluted with waste from the east lagoon, according to a new report for the plant’s operator, Westinghouse Nuclear.

’“It is expected that some contamination will exist in the soil underlying the east lagoon liner, given the long operating history of the lagoon and the potential for a liner system leak,’’ the May 8 report for Westinghouse says.

If the soil below the lagoon is polluted, as Westinghouse suspects, it could indicate that groundwater flowing away from the property and toward the Congaree River has been contaminated.

No one knows the extent of the contamination yet, but Westinghouse has a plan to dig radioactive sludge from the lagoon and haul it across the country for disposal in the Idaho desert.

Once the company has removed the mucky sludge and the lagoon’s 1980s era liner, it plans to test the soil below the waste pond to see how much contamination may be in the earth.

The new Westinghouse consulting report, released by the U.S. Nuclear Regulatory Commission, says sludge in the east lagoon at Westinghouse is contaminated with low enriched uranium and technetium-99, nuclear materials generated as part of production of fuel rods at the 51-year-old factory.

Exposure to sufficient amounts of uranium can cause kidney damage in adults and children. Technetium 99, which concentrates in the thyroid and gastrointestinal tract, can increase a person’s chances of cancer if exposed to certain amounts………

For now, Westinghouse is moving forward with cleanup efforts. Although the company doesn’t plan to clean up some pollution until it closes the plant in future decades, Westinghouse has agreed to get rid of other contamination sooner. …….

The tainted material that would be shipped to Idaho, likely next year, includes 45,000 cubic feet of sludge, soil and debris from the east lagoon, a 160-foot long pond behind the plant on Bluff Road.

Radioactive pond sludge would be hauled away on railroad cars to a U.S. Ecology site in the Owyhee Desert near Grand View, Idaho, according to plans filed with the U.S. Nuclear Regulatory Commission. Contaminated cylinders and a polluted sludge pile also will be carted away from the site for disposal……. https://www.thestate.com/news/local/environment/article242667201.html

Barrow, UK – hub of nuclear weapons work and nuclear transport

Close Capenhurst 10th May 2020, Barrow is best known as the place where BAE Systems build Trident nukiller submarines. The company is also building the Astute-class submarines.

What is less well know is that the ships which transport nukiller waste around the globe go out of the port of Barrow. Neither do most people realise just what else goes on in the town. Pacific Nuclear Transport Limited, a subsidiary of International Nuclear Services, is based at Barrow. The
company website boast that it is ‘the world’s most experienced shipper of nuclear cargoes’. Barrow is also the home port for James Fisher & Sons, which works for the military, and built its first ship suitable fortransporting irradiated nuclear fuel in the 1960s. The company also  provides Nukiller equipment and services.

The search for the 4th hydrogen bomb dropped over Palomares, Spain

Who Do You Call When Nuclear Weapons Go Missing?    Mathematicians.  Here’s What You Need To Remember: With no witnesses, no debris and a search area in the least understood part of the world’s ocean, there’s little even mathematical wizards can do. But even then, few thought 50 years ago that the lost bomb of Palomares would ever turn up.  National Interest, 10 May 20

When a routine Cold War operation went terribly wrong, two planes and seven men died, a village got contaminated and a hydrogen bomb disappeared.

The search and cleanup required 1,400 American and Spanish personnel, a dozen aircraft, 27 U.S. Navy ships and five submarines. It cost more than $120 million and a lot of diplomatic capital.

And it made an obscure 18th-century mathematical theorem a practical solution to finding veritable needles in haystacks.

Around 10 a.m. on Jan. 17, 1966, two B-52Gs of the 31st Bomb Squadron based out of North Carolina approached two KC-135 tankers over the Spanish coast southwest of Cartagena.

The bombers each carried four 1.5-megaton B-28 hydrogen bombs as part of Operation Chrome Dome, a U.S. deterrence mission that placed nuclear-armed bombers on the Soviet Union’s doorsteps.

The resulting breakup destroyed the tanker in a fireball of blazing jet fuel. All four crew on board the tanker died. One hundred tons of flaming wreckage fell upon the arid hamlet of Palomares, near the Mediterranean Sea.

Three of the four H-bombs aboard the bomber fell there, too.

Within 24 hours, a U.S. Air Force disaster team arrived from Torrejon Air Base near Madrid. Specialists from the Los Alamos and Sandia weapons labs — and Air Force logistics units — descended on the tiny rural town.

The search teams found the three H-bombs within a day. One landed on a soft slope, its casing relatively intact. The high explosives within the other two bombs detonated on impact, blowing 100-foot-wide craters in the dry soil and scattering plutonium, uranium and tritium across the landscape.

The region’s long history of human habitation complicated the land search. Almeria, the province where Palomares sits, hosted a mining industry for more than 5,000 years. Countless mine shafts, diggings and depressions pepper its dry landscape made famous by the spaghetti westerns filmed there. ,,,,,,,   https://nationalinterest.org/blog/buzz/who-do-you-call-when-nuclear-weapons-go-missing-152441

Nuclear Regulatory Commission plans a dangerous deregulation of radioactive waste

Critics alarmed by US nuclear agency’s bid to relax rules on radioactive waste https://www.theguardian.com/environment/2020/may/07/nuclear-regulatory-commission-radioactive-waste

Nuclear Regulatory Commission keen to allow material to be disposed of by ‘land burial’ – with potentially damaging effects  Daniel Ross  8 May 2020  The federal agency providing oversight of the commercial nuclear sector is attempting to push through a rule change critics say could allow dangerous amounts of radioactive material to be disposed of in places like municipal landfills, with potentially serious consequences to human health and the environment.

“This would be the most massive deregulation of radioactive waste in American history,” said Dan Hirsch, president of the Committee to Bridge the Gap, a nuclear industry watchdog non-profit, about a proposal that would permit “very low-level” radioactive waste to be disposed of by “land burial”.

Currently, low-level radioactive waste is primarily disposed of in highly regulated sites in Texas, Washington, South Carolina and Utah. The Nuclear Regulatory Commission (NRC) also provides exemptions allowing “low-level waste” to be dumped in unlicensed disposal sites, but these exemptions are given only rarely, and are conducted with strict case-by-case protocols in place.

The proposed “interpretive” rule change relaxes the rules surrounding how radioactive materials would be disposed of in unlicensed disposal sites “significantly”, said Hirsch.

“If you dump radioactive waste in places that aren’t designed to deal with it, it comes back to haunt you. It’s in the air you breathe, the food that you eat, the water you drink,” he added.

In an email, David McIntyre, an NRC spokesperson, explained that the rule would apply only to a “small subset” of very low-level waste, and that the agency would not allow such disposals “if we felt public health and safety and the environment would not be protected”.

But major sticking point, say experts, concerns how the term “very low-level waste” is not defined by statute or in the NRC’s own regulations.

The NRC describes low-level wastes as contaminated materials like clothing, tools, and medical equipment. According to McIntyre, the radioactivity of “very low-level waste” is just above background. “The radioactivity level of very low-level waste is so low that it may be safely disposed of in hazardous or municipal solid waste landfills,” he wrote.

Nevertheless, “background doesn’t mean it’s safe,” said Diane D’Arrigo, radioactive waste project director for the Nuclear Information and Resource Service, who added that the interpretive rule’s loose language “opens the floodgates” for nuclear waste to be disposed of “as if not radioactive”.

The proposal caps the maximum annual “cumulative dose” to a person from the radioactive wastes dumped into unlicensed sites to 25 millirems – the same limit the NRC uses for highly regulated waste disposal sites. That measurement, said D’Arrigo, is a “projected” amount that can be manipulated through modeling.

Experts point out that the nuclear industry has long sought cheaper ways to dispose of its wastes. As the nation’s fleet of nuclear power plants continues to age, and as more of them approach retirement, some of the decommissioning funds set up to safely dismantle the reactors are proving inadequate.

“The NRC regulations are in effect a cost-benefit analysis,” explained Rodney Ewing, a professor of nuclear security at Stanford University. “It’s been a common trend to look for waste streams that, if separated out, they could be disposed of in less expensive ways.”

Some environmentalists fear the rule change will also disproportionately impact low-income, marginalized communities who are more likely than their wealthier neighbors to be situated near solid waste landfills.

According to Caroline Reiser, nuclear energy legal fellow with the Natural Resources Defense Council, if the proposal is successfully passed, then the issue could end up in court.

“Once it starts getting implemented, that’s when the real fights end up happening,” she said.

Lithuania presses Belarus to delay use of nuclear fuel, for safety reasons

Lithuania urges Belarus not to use nuclear fuel delivered to new power plant   https://bnn-news.com/lithuania-urges-belarus-not-to-use-nuclear-fuel-delivered-to-new-power-plant-213078  After Belarus announced that nuclear fuel has been delivered to its new Astravyets nuclear power plant, Lithuania has called on Minsk not to load it into power productions facilities before international safety recommendations have been met, according to the Lithuanian Foreign Ministry.

On Wednesday, May 6, the issue was discussed in a telephone conversation between Minister of Foreign Affairs of Lithuania Linas Linkevičius and Minister of Foreign Affairs of Belarus Vladimir Makei.

Therefore, we urge Belarus not to load nuclear fuel into its nuclear power station until full implementation of the recommendations by international experts. We agreed to consult regularly on all these issues,» told L. Linkevičius as quoted by the Lithuanian Foreign Ministry.

Lithuania’s Ministry of Foreign Affairs also sent a diplomatic note to Belarus, requesting the neighbouring state to give priority to safety rather than to the construction schedule, and to avoid jeopardizing its own residents, as well as citizens in other countries.

A positive step in this direction, as is expected by Lithuania and the European Union, would be to halt the launch of the Belarusian NPP and to immediately organize an official EU expert review of the implementation of the stress test recommendations under the National Action Plan, as well as to promptly welcome a group of international experts that would monitor the process, the Lithuanian Foreign Ministry wrote in the press release.

“Stand-down” of activities at Michigan nuclear reactor, due to certain number of COVID-19 workers

Pandemic concerns interrupt Michigan nuclear plant outage, S and P Global Platts, Author Michael McAuliffe EditorKeiron Greenhalgh CommodityElectric Power   8 May 20  Washington — Some work has resumed after a coronavirus pandemic-caused “stand-down” of activities at DTE Energy’s Fermi-2 nuclear reactor in Newport, Michigan, that interrupted a refueling and maintenance outage, company spokesman Stephen Tait said Thursday.   The “stand-down,” in which contractor work was suspended, would add to the duration to the outage, which began March 21, but the company does “not provide estimates of outage or individual project durations,” Tait said.

DTE previously confirmed it had employees test positive for the novel coronavirus, but Tait said: “As a company, we are not releasing numbers of positive cases.”

The 1,205-MW plant is located in Monroe County, Michigan, and Kim Comerzan, health officer/director of the Monroe County Health Department, said in an interview Thursday the department is working with DTE Energy to determine the number of regular employees and contractors who have tested positive for the virus.

The stand-down began May 1, with some work resuming Monday. Normal crews that maintain the plant remained on the job over the weekend to ensure plant safety, according to Tait.

During refueling outages, hundreds of contract workers are brought in to supplement permanent staff and complete fuel replacement as well as a variety of maintenance tasks and inspections that can only been done with the reactor shut……..

Many nuclear units in the US and overseas have reduced the scope of outages to limit the number of on-site workers and are employing distancing measures to reduce the chance of spreading the novel coronavirus.

While some outages have been completed in shorter-than-normal times as a result, some have been extended both for health reasons and, in some European countries that are heavily reliant on nuclear power, because of a sharp drop in demand for power due to lockdowns related to the pandemic.  https://www.spglobal.com/platts/en/market-insights/podcasts/focus/050620-lng-market-disruption-new-projects

The pandemic is a direct threat to Russia’s secret nuclear cities – says Rosatom chief

Rosatom fears for its nuclear cities amid coronavirus pandemic, The head of Russia’s state nuclear corporation has expressed concerns about the spread of the novel coronavirus to three of its so-called “nuclear cities,” including one that houses a top-secret research institute that helped develop the Soviet nuclear bomb.  May 5, 2020 by Charles Digges  charles@bellona.noThe head of Russia’s state nuclear corporation has expressed concerns about the spread of the novel coronavirus to three of its so-called “nuclear cities,” including one that houses a top-secret research institute that helped develop the Soviet nuclear bomb.

The cities hold a fabled place in Russia’s nuclear industry, which is managed by the state-controled Rosatom corporation. Most of them are closed to foreigners and even most Russians require special permission to enter them because of the top-secret facilities that many of them house.

In his most recent video appearance, Rosatom chief Alexei Likhachev said a special delivery of ventilators and personal protective equipment for medical workers has been sent to the city of Sarov and other closed towns where dozens of cases have been reported.

“This (pandemic) creates a direct threat to our nuclear towns,” Likhachev said in the video address on the Rosatom website ­­­– a communication method he has embraced since the beginning of the pandemic. “The situation in Sarov, Elektrostal, Desnogorsk is today particularly alarming.”

His remarks come as Russia reports a total of 155,370 cases of coronavirus infection and 1,451 deaths, making Russian the seventh most infected country, having surpassed China, Turkey and Iran last week.

The spread of the coronavirus has posed special challenges to the worldwide nuclear industry, where small groups of highly trained specialists are required to safely run reactors and manage nuclear fuel and radioactive waste services in close quarters.

In Russia, Rosatom has moved to sequester its nuclear technicians onsite at the plants and facilities where they work to minimize their exposure to carriers of the coronavirus.

Rosenergoatom, which is the utility subsidiary of Rosatom, hasn’t made clear precisely how many Russian nuclear workers have been put in isolation or ordered to shelter at their plants. But Rosatom controls a sprawling network of reactors, laboratories, commercial structures and fuel fabrication facilities that employ some 250,000 people.

Russia’s 11 commercial nuclear power plants operate a total of 38 nuclear reactors. Rosatom also has 36 power units at different stages of implementation in 12 countries around the world. It is currently constructing seven reactors overseas: two each in Bangladesh, Belarus and India, plus one unit in Turkey.

In a sense, Russian nuclear power and scientific facilities are uniquely designed to handle outbreaks of the virus. The 10 so-called “closed administrative territorial formations,” which were formed as part of the Soviet nuclear weapons program, are nearly entirely off limits for foreigners as well as most Russians.

The cities hosting Russia’s commercial nuclear plants, while less strictly separated from the rest of the country, are nonetheless surrounded by checkpoints and often require foreign visitors to get special permission to enter them.

As of last week, said Likhachev in his address, there were 47 infected personnel among the corporation’s ranks.

In the city of Sarov alone, there have been 23 cases of Covid-19, Likhachev said – 7 of them Rosatom employees.

Known formerly as Arzamas-16, Sarov didn’t even appear on maps until the breakup of the Soviet Union in 1991. It remains home to the All-Russian Scientific Research Institute of Experimental Physics, which made headlines last year when five of its scientists died in a mysterious radiological explosion at a weapons testing site in the Russian Arctic.

The institute, which is now run by Rosatom, is an important part of Russia’s nuclear military complex. Likhachev indicated in his address that the workers who tested positive are affiliated with the institute.

Looking back to May 1986 – the exodus from Kiev, after the Chernobyl nuclear catastrophe

From the Guardian archive Chernobyl nuclear disaster  Exodus from Kiev: aftermath of Chernobyl nuclear accident – archive, 1986

5 May 1986: Moscow has seen many Russians arriving by train from Kiev in the disaster area  Martin Walker The first real signs of alarm among the Soviet public began to emerge over the weekend as Russians arriving by train from Kiev in the Chernobyl disaster area, began saying frankly that they were worried by radiation.

In the last two days large numbers of unescorted children have been arriving here from the city by train, to be met by relatives and grandparents.

“I am very glad to be able to be in Moscow at this time,” a young father, with two daughters, said on arrival at the Kiev Station in Moscow yesterday. “Of course I am worried about radiation. It is not something any government can control.”

There was no sign of any organised evacuation, and the exodus seems to be spontaneous, provoked by the highly publicised visit to the Chernobyl nuclear disaster area last Friday by the Prime Minister, Mr Nikolai Ryzhkov, and the party ideology chief, Mr Yegor Ligachev, perhaps the two most powerful men in the country after Mr Mikhail Gorbachev. Their visit to the area was clearly intended to continue the official campaign of reassurance and to fend off panic. It seems to be having the opposite effect, however. ……

Japanese experts testing Moscow water, milk and foods in their embassy reported yesterday that they had found “low but distinct radiation,” which was the more alarming since winds had not carried the radiation direct to Moscow. The Japanese embassy and Japanese companies are now flying in milk, fruit and vegetables for their personnel.

The head of the International Atomic Energy Agency, Dr Hans Blix, is to arrive in Moscow today, and Soviet authorities have promised to give him “full documentation” of the nuclear accident. But it is not clear whether he will be allowed to visit the site, or if he will be restricted to Moscow.

It emerged over the weekend that some rudimentary precautions were being recommended to the Soviet population. Soviet friends report that their children in Moscow schools had been told that some foodstuffs had been accidentally infected with rat poison in the city warehouses, and that all vegetables should be scrubbed and peeled.

In Kiev, the Greek and Lebanese students still there have been warned by their Soviet liaison officials not to bathe or shower in the local water, nor to drink tap water, and to stay away from the local lake reservoir known as the Sea of Kiev. Bottled water had disappeared from Moscow shops yesterday…….. https://www.theguardian.com/environment/2020/may/05/exodus-from-kiev-aftermath-of-chernobyl-nuclear-accident-archive-1986

As UK’s Torness nuclear power station deteriorates, – cheaper to build renewables than to repair aging reactors

The Ferret 6th May 2020, Cracks that could increase the risk of a radioactive accident at Torness
nuclear power station in East Lothian will start appearing six years sooner than previously thought, according to the UK government’s safety watchdog. The Office for Nuclear Regulation (ONR) said that cracking which could cause debris to inhibit vital cooling of highly radioactive reactor fuel is now predicted to begin in 2022 rather than 2028.

After a major review ONR has given Torness permission to keep operating until 2030 –
but only if inspections to check for cracks are intensified. ONR promises
to “robustly challenge” the plant’s operators, EDF Energy, to ensure
that it “remains safe”.

Campaigners fear that Torness will become
increasingly unsafe, and warn it may have to close down sooner than
expected. EDF, however, insists that the station will keep generating
electricity safely until 2030. The coalition of 50 nuclear-free local
authorities in the UK has called on ONR to keep Torness under close
scrutiny. “These safety reservations surrounding the Torness periodic
safety review need to be cleared up as soon as possible,” said the
group’s Scotland convenor, SNP Glasgow councillor, Feargal Dalton.

“Whilst EDF is having to spend large resources trying to persuade the
regulator that it is safe to restart the Hunterston B reactors, this report
emphasises that similar issues with ageing are likely to arise at Torness
over coming years.” Councils would press ONR “to forensically
scrutinise what look like significant weaknesses in the EDF safety case,”
Dalton added.

“In the meantime, the Scottish Government should start
discussions about a ‘just transition’ for the workers at both
Hunterston and Torness so that Scotland can move to a safe, sustainable and
non-nuclear economy as quickly as possible.” The Edinburgh-based nuclear
consultant, Pete Roche, argued that it could be cheaper to build new
renewable capacity instead of continuing to operate ageing reactors.
“This could soon be the case with Torness, especially if it has to keep
being turned on and off to inspect the graphite core,” he said.
“Scotland clearly needs to be prepared for the possibility that Torness
might be forced to close not long after 2022.”

More delay for Japan to open Onagawa nuclear power plant Unit 2: Unit 1 to be closed

Onagawa 2 upgrade faces further delay, WNN, 04 May 2020

The completion of safety countermeasures at unit 2 of the Onagawa nuclear power plant in Miyagi Prefecture, in Japan, will not be completed until March 2023, two years later than previously scheduled, Tohoku Electric Power Company announced on 30 April. Japan’s nuclear regulator concluded in February the unit meets revised safety standards, clearing the way for it to resume operation.

Tohoku expects to spend about JPY340 billion (USD3.2 billion) on the countermeasures, which include seismic reinforcement of Onagawa 2 and construction of a 29-metre high and 800m long sea wall to protect the plant from tsunamis. The company had originally planned to complete this construction work by April 2017, but the schedule has been pushed back a number of times. The latest plan had been for the countermeasures to be in place by the end of financial year 2020 (ending March 2021).

However, Tokohu has now announced it has reviewed its upgrade works plan for Onagawa 2’s operation. Based on discussions it has had with the Nuclear Regulation Authority (NRA), Tohoku has decided to expand or revise its construction works for improving the facilities at the plant. As a result, the entire plan of construction work has been delayed and is now expected to be completed in FY2022 (ending March 2023).  ……..

Tohoku has already decided to decommission unit 1 of the plant and is considering applying to restart unit 3.  https://www.world-nuclear-news.org/Articles/Further-delay-in-completion-of-Onagawa-2-safety-up

The Southwest Research and Information Center says that rules are ignored in nuclear waste construction in New Mexico

Appeal: New Mexico ignored rules in OK of nuke site work,   https://www.myhighplains.com/news/new-mexico/appeal-new-mexico-ignored-rules-in-ok-of-nuke-site-work/    by: SUSAN MONTOYA BRYAN, Apr 28, 2020, ALBUQUERQUE, N.M. (AP) — A watchdog group wants the New Mexico Court of Appeals to put the brakes on a key construction project at the nation’s only underground nuclear waste repository.The Southwest Research and Information Center alleges state environmental officials ignored regulations and past practices in giving temporary approval for contractors to begin building a new ventilation shaft at the Waste Isolation Pilot Plant.

The state stands by its decision.

A radiation release in 2014 forced the repository’s temporary closure.

Resulting contamination limited the air flow underground, prompting the need for a new system so full-scale operations can resume.

Comment Period For Proposed Nuclear Waste Dump In New Mexico extended by 60 days

60-Day Extension Of Public Comment Period For Proposed Nuclear Waste Dump In New Mexico, KRWG, By NEWS EDITOR AND PARTNERS • MAY 2, 2020   U.S. Senators Tom Udall and Martin Heinrich, and U.S. Representatives Xochitl Torres Small, Ben Ray Luján, and Deb Haaland are welcoming an announcement from the Nuclear Regulatory Commission (NRC) that their March 20 request has been met and a 60-day extension on the public comment period will be implemented for the Draft Environmental Impact Statement for Holtec’s proposed spent nuclear fuel storage facility in Southeast New Mexico.  Here is statement from the office of Senator Martin Heinrich:

“Allowing for full public participation, as NEPA requires, is particularly important for projects involving nuclear waste,” the delegation said. “Any proposal to store commercial spent nuclear fuel raises a number of health, safety and environmental issues, including potential impacts on local agriculture and industry, issues related to the transportation of nuclear waste, and disproportionate impacts on Native American communities.”…….https://www.krwg.org/post/60-day-extension-public-comment-period-proposed-nuclear-waste-dump-new-mexico
