11 April 2013 “…… The C&AG’s report on the 2010-11 WGA shows the Nuclear Decommissioning Authority’s estimated cost of civil nuclear decommissioning increased by around £16 billion to £53 billion between 2007 and 2011. We asked the Treasury how the WGA would be used to influence any decision made in relation to future investments in the nuclear sector. The Treasury acknowledged that not considering these costs when the power stations were built had been a mistake, and considered that the critical issue was to factor in these costs in future, so that the taxpayer would not be burdened with unexpected additional costs of £60 billion.[ http://uk.groups.yahoo.com/group/Claverton/message/10673
Hanford nuclear waste tanks could explode
The nuclear safety board warned about the risk of explosion to Wyden, who wanted comment on the safety and operation of Hanford’s tanks, technical issues that have been raised about the design of a plant to treat the waste in those tanks, and Hanford’s overall safety culture.
Hanford Nuclear Waste Tanks Could Explode, Agency Warns http://www.huffingtonpost.com/2013/04/02/hanford-nuclear-waste-could-explode_n_3001134.html?utm_hp_ref=green includes video By SHANNON DININNY 04/02/13 YAKIMA, Wash. — Underground tanks that hold a stew of toxic, radioactive waste at the nation’s most contaminated nuclear site pose a possible risk of explosion, a nuclear safety board said in advance of confirmation hearings for the next leader of the Energy Department.
State and federal officials have long known that hydrogen gas could build up inside the tanks at the Hanford Nuclear Reservation, leading to an explosion that would release radioactive material. The Defense Nuclear Facilities Safety Board recommended additional monitoring and ventilation of the tanks last fall, and federal officials were working to develop a plan to implement the recommendation.
The board expressed those concerns again Monday to U.S. Sen. Ron Wyden, D-Ore., who is chairman of the Senate Energy and Natural Resources Committee and had sought the board’s perspective about cleanup at Hanford. Read more »
Facts on nuclear waste and the Great lakes
1. Ontario Power Generation (OPG), a multi-billion dollar corporation wholly owned by the Province of Ontario, plans to build a nuclear waste dump at the Bruce Nuclear Power Plant site, Municipality of Kincardine, Ontario “located approximately 1 km inland from the shore of Lake Huron at the surface and more than 400 metres below the deepest near-site point of Lake Huron.” http://tinyurl.com/arc34y2 , page 55 OPG owns all Ontario’s nuclear plants and all radioactive nuclear waste created.

Hanford’s stash of radioactive water
Millions of dollars and labor hours are being spent moving nuclear waste from bad tanks into good tanks. Then millions more will be spent on vitrification. But single-shell or double shell, peanut butter or glass, it will still be nuclear waste. There is no getting rid of it. There is only finding more convenient, less uncomfortable ways to deal. .
At The Hanford Nuclear Reservation, A Steady Drip Of Toxic Trouble by Eric Nusbaum Feb 24, 2013 Eric Nusbaum tours the largest environmental cleanup operation the United States government has ever undertaken. “……There are 200 square miles of contaminated groundwater under Hanford. Every day that water moves closer to the Columbia River. Not coincidentally, there are also 177 massive storage tanks on the site, each built to hold between 55,000 and more than 100,000 gallons of nuclear waste. Read more »
High level radiation stymies Fukushima nuclear decommissioning
No workers were visible around the No. 3 reactor building. An unmanned crane was removing debris on the roof.
It is hazardous to human health to work in the reactor building where
radiation levels range from 20 to 100 millisieverts per hour.
The amount of radioactive water stored in tanks and other facilities
rose to 230,000 tons this month, up from 10,000 tons in July 2011.
In addition, an estimated 100,000 tons of water have accumulated in
the basements of buildings.
Decommissioning will not be completed for the next 30 to 40 years

Nuclear wastes in Gorleben salt mine, Germany
Abyss of Uncertainty: Germany’s Homemade Nuclear Waste Disaster Spiegal online, By Michael Fröhlingsdorf, Udo Ludwig and Alfred Weinzier, 21 Feb 13, Some 126,000 barrels of nuclear waste have been dumped in the Asse II salt mine over the last 50 years. German politicians are pushing for a law promising their removal. But the safety, technical and financial hurdles are enormous, and experts warn that removal is more dangerous than leaving them put……
Germany’s Federal Office for Radiation Protection (BfS) has been responsible for Asse since 2009. This is an agency that was originally founded to monitor things such as the safety of workers in nuclear research facilities. In early 2010, the federal government ordered the BfS to assess whether the radioactive waste in the Asse mine can be retrieved. The agency estimated that it would take three years to prepare the project. Most recently, the BfS said it would need 10 years for the fact-finding phase alone.
The BfS still has no detailed concept for the retrieval, no timetable, no script that maps out the technical procedures. It’s essentially a flight by the seat of the pants, and problems are encountered for which no solutions have been found anywhere in the world…. Read more »
Exposing USA’s fraudulent “Nuclear Waste Confidence Rule”
The only reasonable and logical solution is to stop making more. But this “Waste Confidence” decision isn’t based on reason or logic. It’s based on keeping the reactors OPERATING for the next hundred years.
So why are we burdening our future generations with an ever-growing, unsolvable problem?
The Eternal Problem - Nuclear Waste Confidence, Counter Punch by RUSSELL D. HOFFMAN, JANUARY 03, 2013“………The pro-nuker preferred to call it “spent fuel confidence.” I, on the other hand, didn’t like the word “confidence” since there’s nothing that warrants ANY confidence in this discussion, whatsoever. ”Waste Failure” would be more appropriate. Or “Waste Impasse” might be even better. Or better yet: ”The Intractable, Unsolvable, Filthy, Disgusting Mess We’ve Made” but I guess that would just be too accurate to a group where a “rapid disassembly” is the term for a core explosion that spews radioactive crud for miles around.
But one way or another, it’s obvious that “Waste Confidence” is a misnomer from start to finish…… …… Nuclear waste storage is a huge unsolved problem in every nuclear country. Although France, Japan and several other countries reprocess spent fuel, they have had numerous incidents at thier facilities and numerous releases of radiological materials into the environment. In addition to being dirty, reprocessing is energy-intensive and expensive. For these and other reasons, such as proliferation issues, we do not reprocess spent fuel in America, and don’t expect to.
Instead, we just hold onto it. What else can we do? Read more »
Vermont Yankee nuclear plant’s dangerous radioactive wastes
Vermont, New York regulators urge review of storage of spent nuclear fuel, VT Digger, by Andrew Stein | January 3, 2013 ”……Vermont Yankee has 1,507 fuel rod assemblies submerged in a spent fuel pool, which was originally designed to hold about 350. Spent fuel rods must be kept under water in order to prevent the Zirconium cladding (the metal tubes that contain the fuel pellets) from igniting. The rods can remain hot for several years.
Vermont Yankee’s spent fuel pool, located in a metal warehouse structure, has more than five full reactor cores worth of radioactive material. In the event of an accident, the impact would be five times greater than a single reactor meltdown.
The dry cask storage containers on the site are hundreds of times safer than the spent fuel pool, Shadis said.
At this point, the site has 13 loaded casks, four of which were filled last year, according to Neil Sheehan, NRC public affairs officer for Region 1.
Each cask, which can hold 72 assemblies, costs $1 million. It would cost roughly $11 million to move all of the assemblies into dry cask storage……. http://vtdigger.org/2013/01/03/vermont-new-york-regulators-urge-review-of-spent-nuclear-fuel-storage/
Radioactivity problem in wastes from rare earths processing
Lynas’ waste plans a toxic pipe dream Aliran, 19 December 2012 by Wendy Bacon ” ……While Lynas says it is confident in the current by-product plans, they are yet to be tested. Dr Peter Karamoskas, who has been a nuclear radiologist for 13 years and represents the Australian public on the Radiation Safety Committee of Australia’s nuclear safety agency, shares none of that confidence.
Speaking on his own behalf, Karamoskas said that to be safe more than a million tons of WLP residue with a radioactive reading of 6Bq have to be mixed with five times the amount of aggregate to reduce its reading to 1Bq. While he said that a similar process had been used in the Netherlands, the waste was far less radioactive, sitting near 1Bq, which is the threshold for safety. Read more »
The story of Lynas rare earths project in Malaysia, and its radioactive wastes problem
The IAEA also recommended that Lynas proceed no further until it had filed comprehensive plans for the permanent disposal of waste, decommissioning of the plant and remediation of the site at the end of its life.
Lynas’ waste plans a toxic pipe dream Aliran, 19 December 2012 Scientists and community leaders are concerned about radioactive waste from Lynas’ Malaysian plant but the company representative who took Wendy Bacon’s questions brushed off the criticism. This is the second of two articles about Lynas by Wendy Bacon.Read the first here.http://aliran.com/11005.html
Australian rare earth company Lynas has always known it had a waste problem. Read more »
