Canada is a step closer to picking a place to store spent nuclear fuel underground for the next 100,000 years, a project that’s backfired on some of the world’s other nuclear economies.

Despite the stigma of radioactivity, 22 Canadian municipalities expressed interest in hosting such a facility. Four have now been moved up the list for further evaluation, while seven have been rejected as not suitable. The other 11 are still in the initial assessment phase.

Final approval could take another couple of decades, but if a site is found and approval given to build a Deep Geologic Repository (DGR), the project will generate thousands of jobs, some lasting generations.

Billions would be spent constructing a vast warehouse over 500 metres underground to contain some of the most radioactive waste in the world.

Deadly byproduct

Nuclear energy has helped meet Canada’s electricity needs for more than 40 years, but a deadly byproduct has been steadily building up as a result.

There’s a growing inventory of spent uranium pellets. The radioactive pellets are stored inside long silver tubes bundled together like 24-kilogram logs.

 

hi-candu_fuel_bundle

Spent uranium pellets from nuclear reactors are stored inside long silver tubes that are bundled together like 24-kilogram logs.

Heading the search for a secure place to store those tubes is the Nuclear Waste Management Organisation (NWMO), funded by Canada’s four nuclear agencies, which describes the situation this way: “If Canada’s entire current inventory of just over two million used fuel bundles could be stacked end-to-end, like cordwood, it would fit into six NHL-sized hockey rinks from the ice surface to the top of the boards.”

At present, spent fuel is stored at seven different sites across Canada, including at the reactors it once powered. But that’s not a long-term solution, because in time those reactors will be decommissioned and dismantled.

In its quest for a site, the NWMO took the novel step of asking Canadian communities if they’d think about hosting the highly-radioactive payload.

“Well, we didn’t know what to expect” said Jo-Ann Facella, director of social research and dialogue at the NWMO.

“We put out the plan that Canadians had come forward with and the government had selected as Canada’s plan. And an important part of that plan, it emerged from Canadians, is that these facilities only be implemented in a willing host.”

What also came back were expressions of interest from 22 different municipalities, tempted in part by the promise of employment if they’re chosen. Some were also drawn by the fact that for taking part in the selection process, they’ll get $400,000 even if they’re not chosen, providing they advance far enough in the process and a DGR is ultimately approved.

Westinghouse to go IN to lucrative nuclear decommissioning, OUT of Small Modular reactors (SMRs)

Westinghouse backs out of Small Modular Reactor market Enformable Nuclear News Lucas W Hixson  http://enformable.com/2014/02/westinghouse-backs-small-modular-reactor-market/Danny Roderick, President and CEO of Westinghouse announced that the nuclear firm is backing off of research and development of their Small Modular Reactor design.  The Westinghouse design is a scaled down version of the AP1000 reactor, designed to produce 225 MWe, which could power 45,000 residential houses.

In December, the firm was passed over for a second time by the United States Department of Energy’s SMR commercialization program. Roderick clarified the issue and noted that it was not the deployment of the technology that posed the biggest problem – it was that there were no customers.  “The worst thing to do is get ahead of the market,” he added

SMRs-mirage

According to Roderick, unless Westinghouse was capable of producing 30 to 50 small modular reactors, there was no way that the firm would return its investment in the development project.  In the end, given the lack of market, and the similar lack of federal funding, Westinghouse was unable to justify the economics of small modular reactors at this point.

Westinghouse was working with St. Louis-based Ameren, which had indicated its desire to build a new reactor near the State’s only existing nuclear reactor – the Calloway nuclear power plant, if a federal investment could be secured.

Westinghouse will focus its attentions on its decommissioning business, which is a $1 billion dollar per year business for the firm – which is equivalent to Westinghouse’s new reactor construction business, and rededicate its staff to the AP1000 reactor design.

Highly radioactive Hanford waste site at risk from earthquakes

America’s Most Contaminated Nuclear Site Is Vulnerable To Earthquakes http://io9.com/americas-most-contaminated-nuclear-site-is-vulnerable-1558490796 Mark Strauss 4 April 14 Nearly 2,000 capsules containing radioactive waste at the Hanford Nuclear Reservation need to be relocated. That’s because the site was built in an area that’s prone to earthquakes. How could this happen?

Hanford 2011

The facility, located in in southeastern Washington State, was the world’s largest producer of plutonium during the Cold War. Today, it is America’s most contaminated nuclear site, and the focus of an ongoing cleanup that is costing taxpayers some $2 billion per year.

The 1,936 capsules contain radioactive cesium and strontium that was previously buried in underground tanks, and then later moved into “wet storage”—a 13-foot-deep pool of water that helps cool the corrosive-proof containers, which account for 32 percent of the radioactivity at Hanford.

And, now, according to this Inspector General report from the US Department of Energy, the capsules in the Waste Encapsulation and Storage Facility (WESF) need to be moved yet again:

The March 2011 tsunami and subsequent events at the Fukushima Dai-Ichi Nuclear Power Plant in Okuma and Futaba, Japan highlighted the vulnerabilities to nuclear facilities from possible seismic and natural disasters that are more severe than the facilities’ original design, or “beyond design threats.” One possible threat is a severe earthquake that may result in loss of power and/or loss of water in the WESF pool.

 

Making matters worse—yes, as usual, there’s a “worse”— the report notes that the storage facility has been in service for nine years beyond its design life. The age is beginning to show: the concrete in the WESF pool cells has begun to deteriorate due to years of radiation exposure.

So, it’s now incumbent upon the Energy Department to find a new temporary storage facility. I say “temporary” because we still don’t have a permanent nuclear waste repository. But, no worries, the government has set a goal to open such a facility…in 2048.

Britain now facing a horror cost in burying its dead nuclear reactors

flag-UKNuclear decommissioning A glowing review Britain is paying dearly for neglecting its nuclear waste, The Economist,  Apr 5th 2014  SWILLING around murky ponds in the oldest part of Sellafield, a nuclear research and reprocessing centre in Cumbria, is a soupy, radioactive sludge. For years boffins working on Britain’s first military and civil nuclear programmes abandoned spent fuel and other nastiness into the pools and tanks, which now grow decrepit. Though perhaps not the “slow-motion Chernobyl” which some environmental campaigners make out, the site is subject to one of the most complex nuclear clean-ups in the world.

money-in-wastes-2

Sellafield is the trickiest of several challenges facing the Nuclear Decommissioning Authority (NDA), a government body that manages the contractors who swab out Britain’s defunct facilities. Their projects swallow up about two-thirds of the budget of the Department of Energy and Climate Change; Sellafield alone costs £1.7 billion ($2.8 billion) a year, almost as much as the roughly £2 billion spent subsidising renewable energy in 2013. On March 31st NDA awarded a £7 billion contract to decommission 12 more of Britain’s oldest reactor sites over 14 years to a consortium including Babcock, a British engineering firm, and Fluor, an American one.These big sums reflect problems peculiar to Britain. It ploughed into nuclear bomb-making in the 1940s, and nuclear power in the 1950s, with little plan for how contaminated structures would be dealt with. …….

Mismanagement has probably made a tough job more difficult. In 2009 bosses thought Sellafield would cost £46.6 billion to make safe; the latest estimate is £70 billion, and rising. In February MPs on the public accounts committee slammed the performance of Nuclear Management Partners, the private consortium currently contracted to detoxify it. They questioned NDA’s decision, in October, to award it a second five-year contract, and said taxpayers bore most of the risks……….
Most people now agree that the best solution is to bury it. For years the government has sought councils willing to host such a site in return for jobs and money. Last January politicians in Cumbria vetoed applications from eager councillors in two of its districts. This summer the government will probably nudge them again, and with good reason. Sellafield’s neighbours know as well as anyone what happens when a generation passes the buck. http://www.economist.com/news/britain/21600135-britain-paying-dearly-neglecting-its-nuclear-waste-glowing-review

Entergy’s dilemma – can’t afford to decommission uneconomic Vermont Nuclear Plant

nuke-reactor-deadVermont Nuclear Plant Seeks Decommission But Lacks Funds, Clean Technica 3 April 14,  On Friday, the Vermont Public Service Board voted to authorize Entergy Nuclear Operations, Inc., the operators of the Vermont Yankee electricity generating station at 546 Governor Hunt Rd. in Vernon, to close down their nuclear power plant by the end of this year. Because Entergy planned to shut the Vermont nuclear plant down prior to its licensed end-term, the board was required to approve the shutdown……..

The Vermont nuclear plant is similar to those at TEPCO’s ruined Fukushima Daiichi site………
Vermont Yankee has had detractors for almost all of its 42-year history. Anti-nuclear protests clouded the plant in its first decades of operation. A cooling tower cell collapsed there in 2007, and tritium leaks as high as 2.5 million picocuries (125 times the EPA drinking-water standard) also occurred. Nonetheless, the Nuclear Regulatory Commission renewed the license for the Vermont nuclear plant on March 21 three years ago for operation at 1,912 MWe until 2032.
Entergy announced last August that it intended to shut down the reactor late this year for economic reasons. As has happened elsewhere, declining natural gas prices and low wind power prices are making nuclear-generated power too expensive. Coal-fired plants in the region are also at risk of closure…….

Another remaining issue is a 12-year-old National Pollutant Discharge Elimination Systempermit that has been under review by the Vermont Agency of Natural Resources for the past eight years. Continued discharges of warm water into the Connecticut River appear to have adversely affected water quality downstream and altered ecological systems in the watershed.

Entergy has reserved just over $600 million to date for decommissioning the Vermont nuclear plant, according to the Department of Public Service. This amount will not be adequate to meet the costs of full deconstruction, estimated at more than $1 billion according to the company’s 2012 Decommissioning Cost Analysis report.

The company has pledged to put $25 million toward site restoration after decommissioning the plant. However, presumably, the pledge would be moot if Entergy cannot totally decommission the plant.

“That $400 million gap raises issues about where the money will come from to dismantle the plant safely,” MassLive editorializes. http://cleantechnica.com/2014/04/02/vermont-nuclear-plant-seeks-decommission-lacks-funds/

Now 21 workers radioactively contaminated at New Mexico nuclear waste site

text ionisingTESTS SHOW RADIATION CONTAMINATION ON FOUR MORE WORKERS AT NEW MEXICO Flag-USASITE http://www.nextgov.com/health/2014/04/tests-show-radiation-contamination-four-more-workers-new-mexico-site/81709/?oref=ng-HPriverThe U.S. Energy Department on Monday said testing had revealed trace levels of contamination in four additional workers at a nuclear waste site in New Mexico.

The announcement brings to 21 the total number of Waste Isolation Pilot Plant, or “WIPP,” personnel who were exposed to small amounts of radiation following a February leak of some radioactive elements from the subterranean nuclear-materials dump, the Associated Pressreports.

The department intended to dispatch a team of eight specialists on Tuesday into the underground portion of the nuclear facility to start establishing outposts that would enable a probe into exactly what led to the leak.

The WIPP facility has not accepted any new atomic waste since the discovery of the radiation leak. This has caused some U.S. nuclear-weapons sites to turn to temporary options for storing their waste.

Is this a target for terrorists? Oh no, it’s just a nuclear waste ship

wastes-1Nuclear waste ship in Tasman sea http://www.stuff.co.nz/national/9896660/Nuclear-waste-ship-in-Tasman-sea TIM DONOGHUE 2 April 14 The nuclear waste carrier Pacific Grebe is currently making its way through the northern mid-Tasman sea bound for Japan with canisters of high level reprocessed nuclear waste from Britain on board.

The 6,840 tonne British registered ship, owned by Warrington, UK based Pacific Nuclear Transport, sailed from Barrow-in-Furness, north of Liverpool, bound for Japan on 14 February 2014

The Japan Times reported in January, 2014 that  28 canisters of high-level radioactive waste, produced through the reprocessing of spent Japanese nuclear fuel in Britain, would be transported to the Aomori Prefecture on board Pacific Grebe.

The 28 canisters of vitrified radioactive waste included 14 for Kansai Electric Power Co and seven each for Chubu Electric Power Co. and Chugoku Electric Power Co.

The paper also reported in January that the shipment was the third involving vitrified radioactive waste to be brought to Japan from Britain.

Japan has received 104 canisters of such waste from Britain and plans to receive around 800 more. The 104 canisters have been stored at a facility in the village of Rokkasho, The Japan Times reported.

Decommissioning – a bonanza for nuclear firms

flag-UKGovernment set to award £7bn nuclear decommissioning contract http://www.ft.com/intl/cms/s/0/7a4ee910-b7fa-11e3-92f9-00144feabdc0.html By Gill Plimmer 31 March 14,  A private sector consortium will be told on Monday it has won the £7bn job of decommissioning Britain’s oldest nuclear power plants.

money-in-wastes-2

The work is one of the largest and most sensitive public sector contracts to be awarded in the UK so far. The reactors, built in the 1960s originally to produce plutonium to make nuclear weapons, include those at Sizewell, Hinkley and Dungeness. They are now at the end of their lives and the government is preparing to decommission them this year. The overall contract is worth about £7bn over 14 years.

The Nuclear Decommissioning Authority, the government-funded body responsible for Britain’s state-owned nuclear sites, started the competition two years ago, and work is expected to start in September.

Currently the sites are being run by Magnox, a company owned by Salt Lake City-based EnergySolutions. It is bidding for the new work in partnership with Bechtel. The only Magnox station still in use is in Wylfa in Anglesey, though this is due to stop producing electricity in the next two years.

The contract covers Britain’s 10 reactors as well two old nuclear research sites in Oxfordshire and Dorset. The oldest nuclear power plant, Calder Hall in Cumbria, was the world’s first commercial scale nuclear reactor and was opened by the Queen in 1959 before it closed a decade ago.

The incumbent Magnox is competing against consortiums made up of Amec, Atkins and Rolls-Royce; CH2M Hill, Areva and Serco; and Babcock and Fluor. The clean-up contract that the companies hope to take over employs about 3,000 workers on the 12 ageing nuclear sites across the country.

Unions are concerned that awarding the company to an overseas consortium willerode Britain’s nuclear expertise.

“The reality is the way we are breaking up our nuclear industry will go down as another Great British missed opportunity,” Gary Smith, a GMB spokesman said. “Britain was a world leader in nuclear. Successive governments have hived off our nuclear industry piecemeal. There is absolutely no strategy around nuclear which reflects the fact that wider energy policy is a mess.”

New Mexico site still touted as dump for high level nuclear waste

any-fool-would-know

 

 

that they should stop making the stuff, as it has no place to go!

WIPP still considered for high-level waste By  , March 20, 2014 Despite last month’s radiation leak at the Waste Isolation Pilot Plant, researchers continue to look at the possibility of using WIPP or a facility like it to dispose of high level nuclear waste, a panel of waste experts was told Wednesday at a meeting in Albuquerque. But the leak has been a major setback to the idea.

Rod Ewing, chairman of the U.S. Nuclear Waste Technical Review Board, made clear at the outset of a previously scheduled meeting that the Valentine’s Day WIPP leak was not the reason for the long-scheduled session. But as Ewing and the other panel members discussed broad nuclear waste policy questions and technical issues, WIPP’s recent problems kept intruding on the discussion.

The meeting’s primary purpose was to look at lessons learned at WIPP that might be applied to the disposal of other nuclear waste. In particular, a number of experts talked about the suitability of WIPP or something like it for the disposal of high-level radioactive waste – things like spent nuclear power plant fuel that currently has no place to go……….http://www.abqjournal.com/371437/news/wipp-still-considered-for-highlevel-waste.html

New Mexico nuclear waste may go to Texas

Oscar-wastesNuclear waste from New Mexico lab may go to Texas Chron, By JERI CLAUSING and BETSY BLANEY, Associated Press | March 20, 2014 ALBUQUERQUE, N.M. (AP) — With the government’s only permanent nuclear waste dump shuttered indefinitely by back-to-back accidents, officials are making plans to ship radioactive waste from Los Alamos National Laboratory to rural West Texas.

The Department of Energy and the operator of the Waste Isolation Pilot Plant near Carlsbad in southeastern New Mexico say they have signed an agreement with Waste Control Specialists to truck the waste to its site in Andrews County.

The agreement will help Los Alamos meet a June deadline for getting the last of thousands of barrels of plutonium-contaminated clothing, tools, rags and other debris off its northern New Mexico campus before wildfire season hits its peak.

The waste, which is shipped and stored in huge sealed canisters, would come back to New Mexico for final disposal once the Waste Isolation Pilot Plant reopens……..

The West Texas site has in the past taken some less toxic waste from Los Alamos, but the Waste Isolation Pilot Plant is the nation’s only permanent repository for low-level radioactive waste from nuclear weapons facilities.

Waste Control Specialists is licensed to take radioactive materials such as uranium, plutonium and thorium from commercial power plants, academic institutions and medical schools, as well as some DOE waste. It is also the burial ground for dirt from a Hudson River Superfund site that’s tainted with PCBs, or polychlorinated biphenyls.

Chuck McDonald, a spokesman for the plant, said federal officials are working with regulators at the Texas Commission on Environmental Quality to make sure that storing the Los Alamos waste is allowable under its permits.

The state of New Mexico pressured Los Alamos to get the waste off its campus in the northern New Mexico mountains following a massive 2011 wildfire that lapped at the edges of lab property. The waste from decades of bomb building has been stored outside on a mesa. Following the Waste Isolation Pilot Plant shutdown, the state and Sen. Tom Udall, D-N.M., emphasized that the deadline was non-negotiable.

“Removing waste from the mesa in Los Alamos before fire season is critical to ensure safety in the greater Los Alamos community,” Udall said in a statement Thursday. “I’m pleased we have a temporary solution that will ensure there will not be any significant disruption in cleanup efforts.”……

More releases of Plutonium and Americium from New Mexico nuclear waste site

WIPP officials admit new release of Plutonium and Americium — More expected in future — Nearly double levels seen after February leak — 61 DPM on March 11 vs. 36 DPM in February http://enenews.com/wipp-officials-admit-new-radioactive-release-nearly-double-levels-seen-after-february-leak-61-dpm-on-march-11-vs-36-dpm-in-february?utm_source=feedburner&utm_medium=email&utm_campaign=Feed%3A+ENENews+%28Energy+News%29

 AP, Mar. 19, 2014: New air sampling data from southeastern New Mexico’s troubled nuclear waste dump indicates there has been another small radiation release. […] they believe the contamination is from previous deposits on the inner surface of exhaust ductwork. […] Officials say occasional low-level releases are anticipated, but they should be well within safe limits.

Las Cruces Sun, Mar. 18, 2014 (emphasis added): DOE: Another radiation release reported at WIPP […] Samples collected from the ventilation exhaust recorded 61 disintegrations per minute of americium. DPM measures the amount of radioactive contamination from alpha and beta rays in an area. […] The DOE believes the most recent contamination was residual radioactive particles that were trapped in the ventilation system from the initial radiation leak. […] The DOE said it anticipates additional low-level releases on occasion, but officials expect radiation in the environment will remain at safe levels. New Mexico Environment Department Secretary Ryan Flynn said the state was briefed of the news Tuesday morning and thinks there is nothing to worry about at this time. “The level they detected is low and we don’t believe there was any risk to public health or the environment but we need to investigate more,” he said. […] Department of Energy officials were not available for comment.

Albuquerque Journal, Mar. 19, 2014: One air sample collected March 11 from the ventilation exhaust showed increased levels of americium […] In a statement, WIPP called the release “expected, given the amount of contamination captured by the WIPP ventilation system during the February 14 radiation release event.” Engineers say the contamination comes from previous deposits inside the exhaust ducts, WIPP reported. […] WIPP said it doesn’t expect the release to impact the health of workers, the public or the environment.

KVIA News, Mar. 18, 2014: “This is expected given the amount of contamination captured by the WIPP ventilation system during the February 14 radiation release event,” WIPP’s March 18 statement reads.

Las Cruces Sun, Mar. 18, 2014: Increased radiation in Carlsbad not related to WIPP incidents — Radiation levels appear to be on the rise in Carlsbad and around the Waste Isolation Pilot Plant. Air monitoring results since last month’s radiation leak appear to show the amount of radiation trending upward near Carlsbad, but Department of Energy officials say there is no proof it is related to the leak.  A DOE air monitor stationed on Carlsbad’s eastern border, near the Bureau of Land Management office on Greene Street, has shown an uptick of radiation from 1.6 disintegrations per minute (DPM) on Feb. 18, to 7.1 DPM as recently as March 4. […] The initial radiation leak registered at 36 DPM at the WIPP site […]

Rokkasho a big-box store for nuclear terrorists.

Rokkkasho-reprocessing-plan

After spending tens of billions of dollars and decades on breeder-related programs, Tom Cochran said, countries find it hard to pull the plug.

“You have an entrenched bureaucracy and an entrenched research and development community and commercial interests invested in breeder technology, and these guys don’t go away,” Cochran said. “They’re believers … and they’re not going to give up. The really true believers don’t give up.”……..

“Stealing a weapon is too hard,” Cochran said. “But there is no big risk in fuel assemblies, or in taking things from a bulk handling facility that can be used to make weapons.” In this view, Rokkasho is a kind of big-box store for would-be nuclear terrorists.

A World Awash in a Nuclear Explosive? TruthOut,  19 March 2014 12:24 By Douglas Birch and R. Jeffrey SmithCenter for Public Integrity | Report Washington — A generation after Three Mile Island and Chernobyl, the world is rediscovering the attractions of nuclear power to curb the warming pollution of carbon fuels. And so a new industry focused on plutonium-based nuclear fuel has begun to take shape in the far reaches of Asia, with ambitions to spread elsewhere — and some frightening implications, if Thomas Cochran is correct.

A Washington-based physicist and nuclear contrarian, Cochran helped kill a vast plutonium-based nuclear industrial complex back in the 1970s, and now he’s at it again — lecturing at symposia, standing up at official meetings, and confronting nuclear industry representatives with warnings about how commercializing plutonium will put the public at enormous risk.

Where the story ends isn’t clear. But the stakes are large. Continue reading

Why plutonium is so dangerous

plutonium238_1A World Awash in a Nuclear Explosive? TruthOut,  19 March 2014 12:24 By Douglas Birch and R. Jeffrey SmithCenter for Public Integrity | Report Washington “……..Just a Few Pounds Worth of Plutonium? There’s been a ghoulish debate between officials and independent scientists about how much plutonium is needed to fuel a clandestine bomb. But both agree it’s not much.

The U.S. bomb that destroyed half of Nagasaki in 1945 had 6.2 kilograms of plutonium in it, or 13.6 pounds. But experts say it was over-engineered — only one kilogram fissioned, they concluded later.

The International Atomic Energy Agency nonetheless decided years ago that eight kilograms of plutonium, or 17.6 pounds, are needed to make a bomb and so that’s the quantity its monitoring is geared to stop from getting loose.

Cochran and his NRDC colleague Christopher Paine challenged the IAEA standard in 1995 with a study concluding that only 3 kilograms — 6.6 pounds — would be needed to fashion a “very respectable” bomb with the explosive power of a kiloton, or 1,000 tons of TNT. But no matter who is right, Rokkasho’s annual plutonium production would be enough for 1,000 weapons or more. Continue reading

The Coke Can Plutonium Experiment

On arrival at lecture halls, he would push his stand-in for plutonium into an empty Coke can he had sawn in half. During his talks, he would hold the can up so his audience could see it, and say the contents could incinerate a city. “A six-pack of these is a nuclear arsenal,” he would say.

PuA World Awash in a Nuclear Explosive? TruthOut,  19 March 2014 12:24 By Douglas Birch and R. Jeffrey SmithCenter for Public Integrity | Report Washington #……..The Coke Can Experiment In the abstract, there’s plenty of alarm in official circles. “Just one nuclear weapon exploded in a city — be it New York or Moscow; Tokyo or Beijing; London or Paris — could kill hundreds of thousands of people,” President Barack Obama told the United Nations Security Council in September 2009. “And it would badly destabilize our security, our economies, and our very way of life.”

But Cochran has long criticized the effectiveness of one of Washington’s most costly and elaborate strategies to prevent such a catastrophe — a global effort to detect and capture illicit fissile materials at border crossings and major world ports.

Since 2003 the United States has spent more than $850 million on equipment and training for customs officials at 45 foreign ports so they can scan shipping containers to detect nuclear materials. It’s a daunting assignment. About 432 million shipping containers crisscrossed the oceans in 2009 alone. U.S. ports accept 15 million containers every year. Continue reading
