Sellafield to store nuclear waste on site for up to 100 years
Waste will be stored in a facility until there is a long-term disposal solutionNWE Mail, UK, By Jenny Barwise, 8 June 2018
Sellafield is seeking permission to store extra nuclear waste in a specialised facility on the site for up to 100 years.
An application has been lodged with the county council to built two extra plant rooms in the existing Self Shielded Box Storage (SSBS) facility. The facility itself was granted permission three years ago and completed earlier this year. It is designed solely for the interim storage of boxes of waste from the Magnox storage pond which ceased operations 25 years ago.
The waste would be stored in the facility as an interim measure until a long term disposal solution – such as a geological waste facility which the Government is currently consulting on – was created. ……..
“This year we completed the construction of a new store which will hold hundreds of self-shielded boxes – these are specially built 30-tonne metal containers which safely hold radioactive waste and provide the necessary shielding from the waste inside them.”…….
As well as creating the extra plant rooms, the security fence needs to be raised by four-metres.
The application has been lodged with the county council as it is the authority which deals with minerals and waste matters, but Copeland Council has been consulted on the plans.
Officials at the Waste Isolation Pilot Plant in southern New Mexico confirmed this week that processing and handling resumed June 2.
In disposing the waste, seven 55-gallon (208-liter) drums are wrapped together in a tight formation to go deep inside the ancient salt formation where the repository is located. The idea is that the shifting salt will eventually entomb the waste.
Work was halted when employees found one drum wasn’t aligned with the others that made up the waste package. The package was eventually repacked and disposed of underground.
Officials say no radiation was released and no injuries were reported.
At the Savannah River Site, the future of the Mixed Oxide Fuel Fabrication Facility is in jeopardy after a report last month by the National Nuclear Safety Administration recommended the facility be repurposed to produce plutonium pits while also maximizing pit production activities at Los Alamos National Laboratory in New Mexico.
Fifty pits per year would be produced at SRS and 30 per year at Los Alamos, the report said, and “is the best way to manage the cost, schedule, and risk of such a vital undertaking.”
The MOX project arose from an agreement between the U.S. and Russia to dispose of 68 metric tons of weapons-grade plutonium. The material would be enough to create about 17,000 nuclear weapons. But the project has been beset by years of delays and cost overruns, over which the state has several times sued the federal government.
South Carolina’s legislators said the plan to re-purpose the MOX facility is premature considering shipment of diluted plutonium to the Waste Isolation Pilot Plant hasn’t been fully vetted.
Oyster Creek, the oldest of New Jersey’s four nuclear power plants, will shut down Sept. 17, but some of its main buildings will remain standing for nearly six decades at the Ocean County site.
The company also said it had chosen a method that will span 60 years to complete the dismantling of the plant, versus beginning immediately.
Exelon had originally planned to shutter Oyster Creek in 2019 then, this past February, moved the date up to this October. That’s now going to be mid-September at the end of the station’s current fuel cycle, according to Suzanne D’Ambrosio, spokeswoman for Oyster Creek said Tuesday.
According to the report Exelon filed with the NRC, it has chosen to put the plant into long-term storage — a method known as SAFSTOR — and take advantage of the NRC’s rules on decommissioning plants which allow a company up to 60 years to raze a facility. “The SAFSTOR option is the most economical and radiologically safe plan for decommissioning,” D’Ambrosio said. “It allows for normal radioactive decay, produces less waste and exposes our workers to lower levels of radiation.”
Once it stops producing electricity Sept. 17, the process of moving the radioactive fuel from the reactor core to a spent fuel storage pool begins, something Exelon says should be done by Sept. 30.
In the coming years work will begin to remove some smaller buildings at the site, according to the report. The radioactive spent fuel rods will eventually be removed from the fuel pool and be placed in dry storage casks, a task Exelon says will be done by 2024.
The site will be maintained for 50-plus years until Exelon begins removing the larger components at the site beginning in June 2075 and wrapping up by December 2077, according to its report.
Some of the larger sections of the plant may actually be barged from near the site, according to the report.
The decommissioning is expected to cost the utility about $1.4 billion, Exelon says.
Environmentalists who have long been critical of the 620-megawatt plant, said they are glad to see it close.
“Oyster Creek has been a safety threat to Ocean County, polluting Barnegat Bay, and killing thousands of fish over the years,” said Jeff Tittel, director of the New Jersey Sierra Club. “Shutting down the Oyster Creek plant will reduce the algae blooms, improve fish populations and help restore the overall ecosystem of the Barnegat Bay.”

group’s first pressurized water reactor dismantling is informing new cutting, tooling and waste strategies.
A new partnership agreement between EDF’s decommissioning subsidiary Cyclife and Sweden’s Fortum highlights
EDF’s aim to become a leader in the European nuclear decommissioning space.
Cyclife and Fortum announced May 30 they will jointly develop services in
nuclear decommissioning and waste management, focusing on the Nordic
region. European nuclear decommissioning activity is on the rise as ageing

How many billions-with-a-“b” of your tax dollars is the federal government willing to waste on bad nuclear decisions? It’s in the tens of billions already, with the meter in overdrive.
There’s the $15 billion already plowed into the Yucca Mountain storage site, about 100 miles northwest of Las Vegas, Nev., since 1987. The project has yet to take a thimble of nuclear waste, having been abandoned since 2010. There’s the $4 billion Mixed-Oxide Fuel Fabrication Facility, or MOX, at the Department of Energy’s Savannah River Site. MOX was designed to transform weapons-grade plutonium into commercial reactor fuel as part of a disarmament deal with the Russians. It’s more than a decade old, was supposed to open in 2016, is barely 70 percent complete and is over budget – cost estimates have skyrocketed from $1.4 billion to $17 billion.
And now there’s the multibillion plan to split the job of making plutonium pits between Los Alamos National Laboratory and a re-purposed MOX facility. As the National Nuclear Security Administration unveiled the pit production plan, U.S. Secretary of Energy Rick Perry executed a waiver to terminate MOX construction. MOX would now have to be revamped to churn out 50 pits by 2030, even though a nuclear pit has never been produced in South Carolina and there are questions of whether the complex work is even possible in the Palmetto State’s humidity. LANL would get an estimated $3 billion makeover to expand its production line, even though it has never made more than 11 pits a year and has made exactly zero since 2011; it has to crank out 30 under the new deal.
And that nuclear waste that was destined for MOX? It would end up headed to – wait for it – the Waste Isolation Pilot Plant near Carlsbad in a “dilute and dispose” operation. New Mexico never signed up for this level of waste. South Carolina lawmakers, who want MOX and its 2,000 jobs to remain, say “DOE says it now wants to pursue ‘dilute and dispose,’ but that plan was already considered and rejected…. this could lead to the permanent orphaning of at least 34 metric tons of weapons grade plutonium, enough for thousands of warheads.”
Yes, on one hand, it makes sense to find another mission for MOX – in 10 years, a utility has yet to come forward and say it wants to buy what MOX was ultimately supposed to be selling. And it is certainly politically expedient to throw a multibillion-dollar nuclear job-creator bone to South Carolina – after all, that’s where the head of the U.S. Senate resides.
But on the other, there are real questions about whether the U.S. really needs 80 new pits for an estimated $1.4 trillion-with-a-“t.” The magic 80 number comes from an Obama-era vast weapons modernization make-work plan, and Trump is expected to up that ante. Yet, the United States already has 12,000 spare pits and in storage those “have credible minimum lifetimes in excess of 100 years,” according to an independent advisory panel cited in The Economist. Making pits also produces a lot of waste, and as mentioned above, the nation can’t dispose of the metric tons it already has – more than 70,000 metric tons of used reactor fuel is in temporary facilities in 39 states and 55 metric tons of surplus weapons-grade plutonium is in bunkers at the Energy Department’s Pantex warhead assembly-disassembly plant outside Amarillo and in an old reactor building at the Savannah River Site.
N.M. Democratic Sens. Tom Udall and Martin Heinrich, and Reps. Michelle Lujan Grisham and Ben Ray Luján are saying “instead of wasting billions of dollars exploring the construction of a new facility that will likely never be completed somewhere else, the Department of Energy should immediately move forward with the new, modular plutonium facilities at Los Alamos – as originally endorsed by both Congress and the Nuclear Weapons Council.” And LANL director Terry Wallace says “this commitment by the government to expand our plutonium mission reiterates the critical role we play in ensuring the nation’s security.”
There’s something to be said for going with what you know, and the nation knows LANL can build pits. But there are also billions of reasons to take a hard, unbiased look at what the nation truly needs to keep its nuclear deterrence vibrant.
And what is just expensive and dangerous busy work.
Heller maintains fight to exclude Nevada’s Yucca Mountain as federal nuclear dump site, By
Ripon Advance News Service | June 5, 2018 U.S. Sen. Dean Heller (R-NV) hailed a federal appeals court decision rejecting a Texas petition that sought to compel a licensing decision on the proposed Yucca Mountain nuclear waste storage project in Nevada.
“A nuclear waste repository at Yucca Mountain has the potential to inflict immeasurable harm on the health and safety of Nevadans and our economy, and that’s why I’m pleased with the Fifth Circuit Court of Appeals’ decision today to grant Nevada’s motion to dismiss,” Sen. Heller said after the court issued the ruling on June 1.
The U.S. Court of Appeals for the Fifth Circuit Court granted a motion filed by Nevada to dismiss the Texas lawsuit, which alleged that the federal government had ignored a 2012 deadline to complete the licensing process for the proposed Yucca Mountain nuclear waste repository site.
……… The U.S. Department of Energy (DOE) has spent an estimated $8 billion studying the site and constructing an exploratory tunnel beneath Yucca Mountain – which is pretty much all that exists there now, according to the office. DOE estimates costs could reach $97 billion to construct and operate a repository at the site. Moreover, because no railroad exists to transport waste to the site, one would have to be built through Nevada to the mountain site. The estimated price tag could top $3 billion, according to the EYCMI Office.
Thus far, no federal funds have been allocated for the DOE’s proposed Yucca Mountain site, where proponents think burying the waste combined from 131 different U.S. sites would be the safest bet, while opponents of the plan say the desert mountain’s underground site isn’t a viable option to host a nuclear waste repository because the area is prone to earthquakes and even volcanic activity, according to the ECYMI Office.
……… Sen. Heller, who has been fighting to exclude the Nevada site as the nation’s main location for the permanent disposal of spent nuclear fuel, most recently led successful efforts to ensure that the U.S. Senate excluded the proposed $30 million provision to store defense nuclear waste at Yucca Mountain from the National Defense Authorization Act (NDAA) for Fiscal Year 2019, H.R. 5515…..https://riponadvance.com/stories/heller-maintains-fight-exclude-nevadas-yucca-mountain-federal-nuclear-dump-site/
Santa Fe, NM & Columbia, SC – Two key U.S. Department of Energy documents on future production of plutonium “pits” for nuclear weapons, not previously released to the public, fail to justify new and upgraded production facilities at both the Los Alamos National Laboratory (LANL) in New Mexico and the Savannah River Site (SRS) in South Carolina.
The report reveals that the initial cost estimate for these new and upgraded facilities at both sites is $10 billion by 2030, and around $46 billion in total life cycle costs. Plutonium pits are the fissile cores of nuclear weapons. Cost overruns are the rule for major projects undertaken by the National Security Administration (NNSA), the semi-autonomous nuclear weapons agency within DOE, so the costs are likely to rise yet more, according to Nuclear Watch New Mexico and Savannah River Site Watch.
NNSA’s Pu Pit Production Engineering Assessment, originally marked Unclassified Controlled Nuclear Information, was finalized on April 20, 2018. The 293-page document was obtained by Nuclear Watch and is being released so that the public may be fully informed about the agency’s misguided pursuit of new plutonium pit production facilities for future new-design nuclear weapons. The new NNSA Administrator has called future plutonium pit production her highest priority. But the Engineering Assessment fails to answer the most crucial question: why are at least 80 plutonium pits per year needed to begin with?
As background, on May 10, 2018, NNSA announced in a one-page statement:
To achieve DoD’s [Department of Defense] 80 pits per year requirement by 2030, NNSA’s recommended alternative repurposes the Mixed Oxide Fuel Fabrication Facility at the Savannah River Site in South Carolina to produce plutonium pits while also maximizing pit production activities at Los Alamos National Laboratory in New Mexico. This two-prong approach – with at least 50 pits per year produced at Savannah River and at least 30 pits per year at Los Alamos – is the best way to manage the cost, schedule, and risk of such a vital undertaking.
Nuclear Watch also obtained NNSA’s 14-page Plutonium Pit Production Engineering Assessment (EA) Results. That summary document, dated May 2018, relied on the Trump Administration’s 2018 Nuclear Posture Review for claiming the need for expanded plutonium pit production. However, that high-level review failed to state any concrete justification for the alleged pit need. Moreover, Congress is balking at funding any new pit production facilities at SRS, primarily because Sen Lindsey Graham (R-SC) vociferously opposes repurposing the MOX facility, now undergoing termination, and the New Mexico congressional delegation opposes any pit production outside of the Los Alamos Lab.
The Engineering Assessment details that NNSA analyzed four pit production options, one in the Mixed Oxide (MOX) Fuel Fabrication Facility at SRS and three options at Los Alamos. NNSA chose the most expensive combination, repurposing the MOX facility and increasing pit production at LANL to 30 pits per year. Los Alamos is currently authorized to produce 20 pits per year, but has failed to achieve even that because of ongoing nuclear criticality safety issues (moreover, LANL proposed to produce all 80 pits per year, which NNSA rejected). SRS has never produced pits, raising new nuclear risks at that site and concern about new waste streams.
The Engineering Assessment makes clear that “moderate risks” in the option of repurposing the MOX plant at SRS includes any failure to quickly terminate the MOX project, due to subsequent delays in closing out the project and terminating contracts. Likewise, the report affirms a longheld concern that there is a “very high probability for incomplete construction records/as-built drawings” for the MOX project. On May 10, DOE began congressionally sanctioned termination of the bungled MOX project, but it is being opposed in last-ditch, desperate attempts by Senator Lindsey Graham and the State of South Carolina. The Engineering Assessment makes explicitly clear that terminating the MOX program is the crucial prerequisite for plutonium pit production at SRS and that “some work [on repurposing the MOX plant] can be completed during MOX closeout,” contrary to both the wishes of Congress and requirements of the National Environmental Policy Act.
Expanded plutonium pit production is NOT needed to maintain the safety and reliability of the existing nuclear weapons stockpile, according to Nuclear Watch. In fact, no pit production for the existing nuclear weapons stockpile has been scheduled since 2011, and none is scheduled for the future. Up to 15,000 “excess” pits and another 5,000 in “strategic reserve” are already stored at DOE’s Pantex Plant near Amarillo, TX. In 2006 independent experts found that pits last a least a century1 (they currently average 40 years old). A 2012 follow-on study by the Livermore Lab found that the “graceful aging of plutonium also reduces the immediate need for a modern highcapacity manufacturing facility to replace pits in the stockpile.” 2
Future pit production is for speculative future new designs being pushed by the nuclear weapons labs, so-called Interoperable Warheads for both land- and sub-launched missiles that the Navy does not support. 3 Moreover, as the Engineering Assessment makes clear, future pits will NOT be exact replicas of existing pits. This could have serious potential consequences because heavily modified plutonium pits cannot be full-scale tested, or alternatively could prompt the U.S. to return to nuclear weapons testing, which would have severe international proliferation consequences.
The Engineering Assessment also explicitly links raising the administrative limit on plutonium at LANL’s “Rad Lab” to expanded pit production. This contradicts a recent draft environmental assessment in which NNSA claimed that re-categorizing the Rad Lab as a Hazard Category-3 nuclear facility was necessary only to maintain basic analytical chemistry capabilities, while omitting any reference whatsoever to expanded plutonium pit production.
The Engineering Assessment briefly outlines what could be a major vulnerability to NNSA’s pit production plans, that is the agency’s future compliance (or not) with the National Environmental Policy Act (NEPA). The Assessment states that if “compliance is delayed, [this] extends the schedule, increases costs, and/or delays production.” Both Nuclear Watch and SRS Watch assert that the law requires that major federal proposals be subject to public review and comment before a formal decision is made. Arguably, a formal decision to raise production to 80 pits or more per year necessitates a new or supplemental nation-wide programmatic environmental impact statement (PEIS), which the new dual-site decision strongly buttresses. Follow-on site-specific NEPA documents will then be necessary, with full public participation and hearings. All of this could introduce substantial delays to NNSA’s plutonium pit production plans.
“While it’s clear that the bungled MOX project is unworkable from technical and cost perspectives and must rapidly be terminated, there is no justification to convert the abandoned facility to a nuclear bomb production plant,” said Tom Clements, director of SRS Watch. “We agree that money must now be spent closing and securing the MOX building, but not on the new, unauthorized pit mission. Spending taxpayer funds to now begin conversion of the MOX plant to pit production, as is indicated in the pit report, is premature and can’t even be considered until Congress approves the NNSA approach for new facilities and an environmental impact review with public participation takes place,” added Clements.
Jay Coghlan, Nuclear Watch Director, commented, “NNSA has already tried four times to expand plutonium pit production, only to be defeated by citizen opposition and its own cost overruns and incompetence. We realize that this fifth attempt at a new pit plant is the most serious yet, but we remain confident it too will fall apart. The enormous financial and environmental costs of new nuclear bomb factories and the fact that expanded plutonium pit production is simply not needed for the existing nuclear weapons stockpile will doom this effort. We think the American public will reject new-design nuclear weapons, which is what this expanded pit production decision is really all about.”
Barry GEM 29th May 2018 Graham Vodden: I read with interest your article in The GEM regarding Hinkley Mud, and I have to say that I have no confidence in the National Assembly making the correct decision on this matter. I fully endorse the petition calling for the licence to be suspended to allow for a full environmental assessment before any dredging and dumping is started.
We already have a problem with excess mud coming ashore on Penarth beach because somebody decided years ago to dump local dredged mud out of Cardiff Dock entrance at the North Cardiff buoy, instead of where it used to be dumped at the Middle Pool buoy, where it would disperse and not cause any environmental problem.
The question that needs to be addressed is why does EDF want to bring this mud all the way from Hinkley beach to the North Cardiff Buoy position for dumping? The answer to that is there is already a licence issued for dumping mud or sediment here, which makes the whole process easier.
The other question which needs to be asked is why can’t they dump this sediment outside Hinkley? There is plenty of depth in that part of the channel and it would not cause any problems, it would just disperse. The answer to that is that EDF would have to go through the whole process of licence application again. My message to EDF is, keep your suspect ‘mud’ in the area of Hinkley. The last thing Penarth needs is a massive mud pollution increase on our beach. http://www.barry-today.co.uk/article.cfm?id=119999&headline=Why%20does%20EDF%20want%20%20to%20dump%20mud%20from%20%20Hinkley%20on%20our%20coast?§ionIs=news&searchyear=2018
interim stores in places such as Fort St. Vrain could be in business not just for decades but for centuries. The nuclear-waste time bomb will keep ticking.
The 60-Year Downfall of Nuclear Power in the U.S. Has Left a Huge Mess The demand for atomic energy is in decline. But before the country can abandon its plants, there’s six decades of waste to deal with. The Atlantic , FRED PEARCE It was just another day in the life of the defunct
a remote part of Washington State that made most of the plutonium in America’s Cold War arsenal. On the morning ofMay 9, 2017, alarms sounded. Around 2,000 site workers were told to take cover indoors, and aircraft were banned from flying over the site for several hours. The roof of a tunnel had collapsed, exposing railcars that had been loaded with radioactive waste from plutonium production and then shunted underground and sealed in decades before.
There was other stuff down there too. Nobody quite knew what. Record keeping was poor, but the contents of the tunnels certainly included carcasses from animal radiation experiments, including a reported 18 alligators. The emergency lasted only a few hours. The integrity of the waste was restored. But it was a chilling reminder of the site’s perilous radioactive legacy.
Sprawling across 600 square miles of sagebrush semidesert, Hanford is a $100 billion cleanup burden, full of accidents waiting to happen. It is the biggest headache, but very far from being the only one, emerging in what increasingly look like the final years of America’s nuclear age.
It is 60 years since America’s first commercial nuclear power station was opened by President Dwight D. Eisenhower at Shippingport, near Pittsburgh, Pennsylvania, on May 26, 1958. But the hopes of a nuclear future with power “too cheap to meter” are now all but over. All that is left is the trillion-dollar cleanup.
Public fear and suspicion about all things nuclear grew sharply after March 1979, when the cooling system at Three Mile Island Nuclear Generating Station failed and triggered a meltdown. In the end, actual releases of radiation were minimal, but the incident left behind a reputational mess in addition to the radiological one. On the day of the accident, the United States had 140 operating nuclear reactors, with 92 under construction and 28 more awaiting official approval. In the next five years, more than 50 orders for new nuclear reactors in America were canceled. New contracts entirely dried up.
Hanford has not produced plutonium for three decades. Nobody is making new material for bombs anymore. President Trump’s plans for more weapons can be met by recycling existing plutonium stocks. And even the civil nuclear industry, which still generates a fifth of America’s electricity, is in what looks like terminal decline. With cheap natural gas and renewable solar and wind energy increasingly available, the numbers no longer add up. Nuclear power plants across the nation are being closed with years of licensed operation unused.
No new nuclear power stations have come on line in the past two decades. The only new build underway, two additional reactors at Georgia Power’s Alvin W. Vogtle plant near Waynesboro, is five years behind schedule and has seen its costs double. Its planned completion in 2022 remains uncertain.
America’s 99 remaining operational nuclear power reactors, which still deliver power to the grid, are too important to be closed overnight. But nearly half are over 40 years old. The only question is how long the regulators and accountants will allow them to keep going.
Oyster Creek in New Jersey disconnects from the grid in October with 11 years left on its license. Indian Point in New York State is to shut by 2021 due to falling revenues and rising costs. In California, Diablo Canyon is being closed by state regulators in 2025. The reactor at Three Mile Island in Pennsylvania that survived the 1979 accident will finally shut in 2019.
Shutdown is only the beginning of the end. Final closure and clearance of the sites can take decades, and the waste crisis created by decommissioning cannot be dodged. Lethal radioactive material is accumulating at dozens of power plants, military facilities, and interim stores across the country.
Some, like the train cars buried at Hanford, is evidently in a precarious situation. Much more needs urgent attention. Cleaning up and safely disposing of the residues of the nuclear adventure—much of it waste with a half-life measured in tens of thousands of years—is turning into a trillion-dollar nightmare for the nation. ………..
How did the United States reach this impasse? Back in 1982, the Nuclear Waste Policy Act established that it was the government’s job to deal with this ultimate back-end problem. The act obliged Washington to begin removing used fuel from stores and other facilities by 1998 for eventual disposal at a federal facility. In 1987, Yucca Mountain, near the former Nevada bomb-testing grounds, was chosen to be the sole such facility.In the 1990s, a five-mile tunnel was dug into the remote mountain. Then work stopped, in part because of vehement state opposition and in part because of concerns raised by geologists that a future volcanic eruption could propel buried waste back to the surface. One of President Obama’s first acts on taking office in 2009 was to formally abandon the $100 billion project. Things headed for the courts, which began awarding damages to power companies unable to make use of the nonexistent federal facility. The payouts amount to around half a billion dollars a year, and by 2022 will likely reach $29 billion.
Now President Trump wants to revive Yucca. His 2019 budget request included $120 million for the task. But the state opposition remains as strong as ever, and only $50 million was included in the final budget for Yucca-related items. Maybe Yucca Mountain will make a comeback. If not, then with no alternatives on the horizon, utilities will carry on being paid to keep spent fuel in pools next to abandoned nuclear power plants, and the interim stores in places such as Fort St. Vrain could be in business not just for decades but for centuries. The nuclear-waste time bomb will keep ticking.

The 60-Year Downfall of Nuclear Power in the U.S. Has Left a Huge Mess The demand for atomic energy is in decline. But before the country can abandon its plants, there’s six decades of waste to deal with. The Atlantic , FRED PEARCE,
“……… The true heartland of America’s nuclear enterprise has always been Hanford. And it is the biggest and most toxic cleanup legacy too. Straddling the Columbia River, the Hanford nuclear reservation was America’s primary bomb-making factory. It was where they made the plutonium. At peak production, during the 1960s, its nine reactors irradiated 7,000 metric tons of uranium fuel annually. The intense radiation inside the reactors produced plutonium that was then extracted at five reprocessing plants. Hanford produced a total of 67 metric tons of the metal for the American arsenal, before business halted after the Cold War ended.Plutonium production was a huge task. It required much of the electricity generated at the giant Grand Coulee Dam upstream on the Columbia, the largest hydroelectric power producer in the United States. And the mess left behind is equally mind-boggling. Since production ceased, Hanford has been conducting the country’s largest-ever environmental cleanup program. The current expenditure is $2.3 billion a year. By the time it is done the bill will be more than $100 billion.
The site holds an estimated 25 million cubic feet of solid, radioactive waste. Much of it is buried in over 40 miles of trenches and tunnels, up to 24 feet deep, including the stretch that caved in last year. Elsewhere, there are two corroding cooling ponds, each the size of an Olympic swimming pool, containing some 2,000 tons of spent fuel that never got reprocessed.
But the headline Hanford problem is the 56 million gallons of acidic and highly radioactive liquids and sludges, stored in 177 giant tanks, each up to 75 feet in diameter. They are the solvent leftovers from reprocessing, and contain around twice the total radioactivity released from the world’s worst nuclear accident to date, the 1986 explosion at the Chernobyl power station in Ukraine.
The tanks have been leaking for over half a century. Around a million gallons are slowly spreading toward the Columbia River, in a plume of contaminated soil covering 80 square miles. Protecting the river and its rich salmon habitat from the radioactive pollution is the number-one cleanup priority for the site’s custodians at the Department of Energy. To head off the flows, engineers are constantly pumping out radioactive water.
A better idea is to stop the leaks at the source by emptying the tanks and solidifying the liquids. The current aim is to heat them with glass-forming materials to create solid blocks that could one day be buried deep underground—maybe at Yucca Mountain. Work on a plant to do this began in 2002. It is currently 25 years behind schedule. Operations are not set to begin until 2036 and, once underway, would take 40 years.
At $17 billion and counting, the project is way over budget. Former plant engineers who have turned whistle-blowers believe it won’t be fit for the job and should be abandoned. They warn of a serious risk that particles of plutonium may settle out in the plant processing tanks, creating the potential for an accidental explosion with a big release of radiation.
The task at Hanford grows ever more daunting. After almost three decades, little of the waste and few of the tanks or processing plants have been cleaned up. Far away in Washington, D.C., some question the continuing money sink. It seems to some like a 21st-century pork barrel. Perhaps, critics say, it would be better to put up a fence and walk away. President Trump, while so far publicly supporting the Hanford cleanup, may privately agree. He has slashed its annual budget by $230 million, or about 10 percent.
Local environmentalists are scandalized. “We have got to clean up the site,” says Dan Serres, the conservation director of Columbia Riverkeeper, a local NGO. The tanks should be emptied and the trenches dug up. “In a hundred years, I’d hope the Native Americans have their treaty rights to this land restored,” agrees Chuck Johnson, of Physicians for Social Responsibility. But Tom Carpenter, the executive director of Hanford Challenge, who sits on an advisory board at the Hanford Concerns Council, told me: “You are never going to dig all the waste there up.” The tanks will have to be dealt with, but “most of Hanford’s waste volume-wise is going to stay put. Hanford is going to be a national sacrifice zone for hundreds of years.”

“……… Rocky Flats Wildlife Refuge is an oasis of prairie biodiversity covering 5,000 acres, home to prairie dogs, elk, monarch butterflies, and rare xeric grasses. It also serves as a buffer zone around the site of the largest completed nuclear cleanup to date in the United States. And David Lucas of the U.S. Fish and Wildlife Service is preparing to open it for public access in summer 2018. He’s reckoning on 150,000 visitors a year.During the Cold War, Rocky Flats was secretly machining plutonium manufactured at Hanford into some 70,000 spheres that formed the explosive heart of each weapon in Uncle Sam’s nuclear arsenal. Plutonium pollution was routine. The plant had nowhere to get rid of the day-to-day plutonium waste, which was often dumped in hastily dug landfills or sprayed onto grassland around the plant. At an outdoor compound known as pad 903, where more than 5,000 drums of waste liquids contaminated with plutonium are stored, there’s been substantial leakage. An internal memo reported that rabbits living on the site were heavily contaminated, especially in their hind feet.
A whistle-blower’s allegations about illegal late-night incineration of plutonium waste at the plant led to an FBI raid in 1989. After that—and with demand for plutonium spheres declining following the end of the Cold War—the government closed the site. A federal grand jury sat for three years to hear testimony from the FBI raid. But two days after the jury approved indictments, the Justice Department struck a deal with Rockwell Automation, the company that managed the plant. The company pleaded guilty to some minor charges, but the FBI evidence and grand jury conclusions were sealed forever.
After the cover-up came the cleanup. The core plutonium-handling areas were declared a Superfund site, qualifying for a federal decontamination, which was completed in 2005. The federal government called it “the largest and most successful environmental cleanup in history.” But in reality it was a cut-price job. The original project was estimated at $37 billion, but Congress would sanction only $7 billion. So processing buildings were demolished, but basements and 25 miles of underground tunnels and pipelines were left behind, according to LeRoy Moore, a veteran activist who sat on a public committee in the 1980s that considered the cleanup plans.
Today, the land that housed the industrial complex remains behind a sturdy fence under the control of the Department of Energy (DOE). But the large grassland buffer zone that once protected the complex from prying eyes has been released into the care of the Fish and Wildlife Service for public access.
There are two concerns. First that, as I saw on a tour with Lucas, the fenced-off core area hardly looks self-contained. Earth slips have left ugly gashes up to 300 feet wide across a former landfill site that overlooks a creek running through the wildlife refuge. The DOE’s Scott Surovchak concedes that “slumping is very common” after heavy rain. Only constant repairs, it seems, will prevent the landfills and buried contaminated buildings and pipework from being exposed.
The second concern is the safety of the buffer zone itself. Harvey Nichols, a biologist from the University of Colorado, has found that when the plant was operating snow falling nearby was often “hot.” Falling snowflakes captured tiny plutonium particles that evaded the stack filter. Just two days of snowfall could deposit about 14 million particles on every acre of the site. “There must be tens of billions of particles in the soil today,” he told me.
The Environmental Protection Agency has dismissed such concerns. In 2006 it found plutonium levels in soil samples in the buffer zone were within acceptable limits and concluded that the lands comprising the refuge are “suitable for unlimited use and unrestricted exposure.” But Moore, the activist, is unimpressed. “Prairie dogs and other critters will burrow down for several feet and bring plutonium to the surface,” he says. “Children will be exposed to plutonium. And people will start taking plutonium out into their communities on boots and cycle wheels. Why would we allow that?”
Lucas is unmoved. “We need to get people out here on the refuge. Then the fears will evaporate,” he told me. But that is just what worries his opponents. Forgetting about the plutonium is the worst thing that could happen, they say……….This piece is adapted from Pearce’s new book, Fallout: Disasters, Lies, and the Legacy of the Nuclear Age.
The 60-Year Downfall of Nuclear Power in the U.S. Has Left a Huge Mess The demand for atomic energy is in decline. But before the country can abandon its plants, there’s six decades of waste to deal with. The Atlantic , FRED PEARCE,
“…….. About 30 miles northeast of Rocky Flats, out on the prairie near the small town of Platteville, is the Fort St. Vrain spent-fuel store. It resembles nothing so much as an outsize grain store, but since the 1990s it has been holding 1,400 spent fuel rods, laced with plutonium and encased in blocks of graphite. The spent fuel was left behind when the neighboring nuclear power plant shut. The plan had been to send it to another temporary store at the Idaho National Laboratory, but the governor of Idaho banned the shipment. The Fort St. Vrain facility is designed to withstand earthquakes, tornado winds of up to 360 miles per hour, and flooding six feet deep. Also time. It will be several decades at least before the federal government finds the fuel a final resting place.
The country is littered with such caches of spent fuel stuck in limbo. According to the Government Accountability Office (GAO), 80,000 metric tons of spent fuel, the most dangerous of all nuclear wastes, is stored at 80 sites in 35 states. The sites include stores at past and present power plants such as Maine Yankee, and stand-alone federal sites such as Fort St. Vrain. As the GAO puts it: “After spending decades and billions of dollars … the future prospects for permanent disposal remain unclear.” Nobody wants to give the stuff a forever home.
Nuclear waste is conventionally categorized as high-, intermediate-, or low-level. Low-level waste includes everything from discarded protective clothing to plant equipment and lab waste. It can usually be treated like any other hazardous waste, which in practice usually means burial in drums in landfills or concrete-lined trenches.
Intermediate waste contains radioactive materials with isotopes that decay with half-lives long enough to require long-term incarceration. It includes many reactor components, as well as chemical sludges and liquids from processing radioactive materials, which can often be solidified in concrete blocks. Once solid, intermediate waste can be buried safely in shallow graves, though anything containing plutonium will have to be disposed of deep underground because of the very long half-life.
Much of America’s intermediate-level waste will end up at the country’s largest deep-burial site for such radioactive material. The U.S. military’s Waste Isolation Pilot Plant in salt beds near Carlsbad, New Mexico, could eventually take 6.2 million cubic feet of waste. But it has had problems that have slowed progress and raised questions about its viability.
A chemical explosion in 2014 sprayed the tunnels dug into the salt beds with a white, radioactive foam. When a ventilation filter failed, some of the plutonium reached the surface, where at least 17 surface workers were contaminated. The military shut the tunnels for three years to clean up. While WIPP is today back in business, full operations cannot resume until a new ventilation system is in place, probably in 2021. The eventual cost of the accident, including keeping the dump open longer to catch up with the waste backlog, has been put at $2 billion.
High-level waste is the nastiest stuff. It includes all spent fuel and a range of highly radioactive waste liquids produced when spent fuel is reprocessed, a chemical treatment that extracts the plutonium. Most of America’s high-level waste liquids—and around 30 percent of the world’s total—are in tanks at Hanford.
High-level waste is either very radioactive and will stay so for a long time, or it generates heat and so requires keeping cool. Usually both. It accounts for more than 95 percent of all the radioactivity in America’s nuclear waste, and needs to be kept out of harm’s way for thousands of years.
There is general agreement that the only way to keep high-level waste safe is by turning the liquids into solids and then burying it all deep underground, somewhere where neither water nor seismic activity is likely to bring the radioactivity to the surface, and where nobody is likely to stumble on it unexpectedly. There is disagreement, however, about whether this buried waste should be kept retrievable in case future technologies could make it safer sooner, or whether accessibility simply places a burden of guardianship on future generations.
Before it can be buried, most high-level waste needs to be stored for up to a century while it cools. Unfortunately, this has encouraged countries to put off making plans. None of the world’s high-level waste currently has any permanent resting place. The planet is instead peppered with interim stores. America is no better. Its 90,000 metric tons of high-level waste—set to rise to as much as 140,000 tonnes by the time the last power plant closes—is mostly sitting in ponds at dozens of power stations or lockups like Fort St. Vrain………..https://www.theatlantic.com/science/archive/2018/05/the-60-year-downfall-of-nuclear-power-in-the-us-has-left-a-huge-mess/560945/
Federal Nuclear Dumping in Nevada Stirs Statewide Resentment,
For decades, the federal government has treated Nevada as a radioactive waste dumping ground, now the state is fighting back U.S. News byMichael Green May 29, 2018
NEVADANS CAN BE FORGIVEN FOR THINKING THEY ARE IN AN ENDLESS LOOP OF “THE WALKING DEAD” TV SERIES. Their least-favorite zombie federal project refuses to die.
In 2010, Congress had abandoned plans to turn Yucca Mountain, about 100 miles northwest of Las Vegas, into the nation’s only federal dump for nuclear waste so radioactive it requires permanent isolation. And the House recently voted by a wide margin to resume these efforts.
While teaching and writing about the state’s history for more than 30 years, I have followed the Yucca Mountain fight from the beginning — as well as how Nevadans’ views have evolved on all things nuclear. The project could well go forward, but I believe that it probably won’t as long as there are political benefits to stopping it.
Council opposed to shipping radioactive waste through city Albuquerque Journal By Steve Knight / Journal Staff Writer May 28th, 2018 Albuquerque city councilors voted 4-3 – with one abstention – to approve a memorial opposing transportation of high-level radioactive waste by railway through the city for temporary consolidated storage in southeastern New Mexico……..
The memorial is in reaction to a Holtec International application to the Nuclear Regulatory Commission for a license to store up to 100,000 tons of spent nuclear reactor fuel in a temporary in-ground storage facility in Lea County, halfway between Carlsbad and Hobbs.
But the highlight – if there is such a thing when discussing the issue of nuclear waste – came when Sam Pruitt, a sixth-grade student-to-be at Monte Vista Elementary School, had his say about the matter.
Barry GEM 28th May 2018 ,Richard Bramhall. Referring to The GEM’s recent article on the dumping of
mud from Hinkley Point in the Bristol Channel, campaigners oppose the
dumping not because of ‘passion’ but because of science.
EDF’s references to bananas, radon and cosmic rays are unscientific. Potassium 40
(in the bananas), radon and cosmic rays are evenly distributed in body
tissue and the radiation effects are well understood.
The radioactive particles which EdF refuses to look for in the mud are quite different. The
UN has published data showing enormous amounts of particulates from Hinkley
Point. These are microscopic fragments of uranium oxide and probably
plutonium which are small enough to inhale. From the lung they can travel
anywhere in the body — to the lymph nodes, for example. Such particles
emit very short-range radiations all the time, continually hitting the
cells within a few microns. To treat this as an average all-body dose is
like thinking you can safely keep your baby warm by tucking a soldering
iron into her babygro. The Government laboratory that tested mud samples
did not use techniques capable of detecting uranium or plutonium. This is
why campaigners demand thorough testing. http://www.barry-today.co.uk/article.cfm?id=119988&headline=%E2%80%98Hinkley%20Point%20mud%20needs%20more%20testing%E2%80%99%20%E2%80%93%20a%20GEM%20reader%27s%20letter§ionIs=news&searchyear=2018
The nuclear industry and the U.S. Nuclear Regulatory Commission are threatening to restart Pennsylvania’s permanently closed and decommissioning Three Mile Island Unit 1 nuclear power station. Three expert speakers will present the resistance to this dangerous misadventure in a webinar hosted by the Clamshell Alliance, Beyond Nuclear and Massachusetts Peace Action.
