Severe reactor accidents can be mitigated, and are unlikely to release much -- if any --radioactivity even if they are not, NRC staffers said March 11. The NRC's state-of-the-art reactor consequences analysis, or Soarca, attempts to quantify the probability and likely offsite health consequences of severe reactor accidents, beginning with Exelon Nuclear's Peach Bottom and Dominion's Surry plants. Analysis for those stations has been completed and a report will be completed by May, NRC's Charles Tinkler said in his presentation at the agency's annual Regulatory Information Conference in Rockville, Maryland. Jason Schaperow of NRC said the staff's "preliminary conclusions" are that all accident scenarios analyzed for Peach Bottom and Surry "can reasonably be mitigated." Sensitivity analyses concluded that, even if no mitigation measures were taken, there would be no large early releases of radioactivity, due to the relatively slow progression of the accidents and the small probability of containment failure, Schaperow said. Likely radioactive releases from the accidents analyzed so far in Soarca "are dramatically smaller" than those predicted in a 1982 NRC analysis conducted for use in siting new units, Schaperow said. The late Commissioner Edward McGaffigan and some industry officials were highly critical of that report, which they said was unrealistically conservative in its assumptions.

Responding to a Freedom of Information Act request filed by the Friends of the Earth environmental organization, the U.S. Dept. of Energy (DOE) recently released color photos of 18-wheeler trucks used to transport weapons grade plutonium, uranium and other nuclear materials over local highways to the Savannah River Nuclear Site for disposal. Prior to the DOE release, the only public image of the trucks and their escort vehicles belonged to Tom Clements, the Southeastern Campaign Coordinator of Friends of the Earth, who snapped a photo of the vehicles leaving the Charleston Naval Weapons Station with plutonium shipments bound of SRS and Duke Energy's Catawba reactor in 2005. The trucks in the recently released DOE photos are likely the same type as those used in recent plutonium shipments from the Hanford site in Washington State to the Savannah River Site (SRS). The K-Area Material Storage facility at SRS is slated to house approximately 13 metric tons of "non-pit" (never weaponized) plutonium, Allen Gunter, an SRS-based DOE manager, told City Paper in a Jan., 2008 report.

A coalition of six anti-nuclear groups, including the Natural Resources Defense Council and Livermore's Tri-Valley CAREs, on Wednesday released its in-depth blueprint for steering Obama administration policy toward a nuclear weapons-free future. The timing of the report's release was deliberate: It was intended to get to President Barack Obama's desk before a bipartisan congressional committee releases its own report in early May to guide the president's thinking as he prepares a new nuclear weapons policy. Obama's eagerly-anticipated "2009 Nuclear Posture Review" is due this year, and will lay out the nation's guiding principles for a reduction of its nuclear weapons stockpile and for maintaining the viability of existing warheads to serve as a credible nuclear deterrent. The anti-nuclear coalition, called the Nuclear Weapons Complex Consolidation Policy Network, calls for slashing the U.S. nuclear stockpile to 500 weapons from 2015 to 2020, and for scaling down the nuclear weapons complex from eight sites to three.

"Studsvik of Sweden has signed a contract with Finland's Teollisuuden Voima Oyj (TVO) for the dismantling and metal recycling of old steam generators from the Olkiluoto nuclear power plant. Studsvik-steam generator A steam generator for treatment at Studsvik (Image: Studsvik) Studsvik's facility near Nyköping, Sweden, melts metal scrap, such as stainless steel, carbon steel, copper, aluminium or lead. Melting reduces the volume and weight of the waste, resulting in reduced costs for interim on-site storage and final disposal. The end-product is metal ingots, which can either be immediately free-released as conventional scrap metal or released after a period of decay storage. Residual products (slag, sorted material, cutting and blasting residues and dust from the ventilation filters) and ingots that cannot be free-released are returned to the customer."

More than five years ago, Mordechai Vanunu, a former technician at the Israeli nuclear facility in Dimona, was released from prison after serving 18 years for revealing Israel's nuclear weapons secrets. This week he was arrested again in Jerusalem, accused of talking to foreigners, in breach of conditions imposed on his release. It was in 1986 that Vanunu told his story to the Sunday Times and was lured to Italy by a Mossad agent, where he was drugged and sent back to Israel, charged with treason and espionage. He emerged from prison in 2004 believing even more passionately in a nuclear-free world, and non-violence as a solution to the problems in the Middle East.

Scanning previous internet "news" reports, two stand out in regard to the Portsmouth Gaseous Diffusion Plant: A Tornado and suspicions regarding buried Huntington Pilot Plant materials. Scioto and Pike Counties in Ohio often experience more intense wind bursts when summer thunder storms form and occasionally turn to tornadoes. On July 11, 2009, NBC reported that "some damage" had been reported at the plant from a "tornado-like storm," based on word from public information officer Jack Williams the damage did not impact plant operations. In 1993, residents complained about an alleged 2.5 hour "unreported release." They alleged 13 workers were checked for exposure but no sirens sounded. However, after investigation, those responsible for the plant indicated that the 'release' was not a threat to those outside the plant. The Portsmouth facility has sirens for public notification.

Jason Kish's November 21 letter misses the point I made about Potassium Iodide (KI) pills. I wasn't referring to the effectiveness of KI pills protecting the thyroid gland from a concentration of radioactive iodine released in a nuclear plant disaster. The myth I referred to is the false assumption made by many that KI pills are the magic protector in the event of an accident or terrorist attack at Limerick Nuclear Plant, when in reality, KI pills would only protect one gland from one radionuclide. That inaccurate assumption is made because when handing out KI pills, the public is not provided with full disclosure of all the radionuclides that would be released in a nuclear disaster, for which KI pills will not protect us. It's time to tell the whole truth .

"Rep. Edward J. Markey, D-Mass., Chairman of the Energy and Environment Subcommittee of the Energy and Commerce Committee, today released a staff report entitled "Radioactive Roulette: How the Nuclear Regulatory Commission's Cancer Patient Radiation Rules Gamble with Public Health and Safety." The Markey staff report was prepared after reviewing NRC's latest response to an inquiry by Chairman Markey into the NRC's regulations surrounding the treatment of cancer patients with radionuclides as well as other materials. "With the release of this report, I call upon the NRC to immediately reverse its actions and stop gambling with public health and safety - and if it won't, I will introduce legislation that will direct it to do so," said Rep. Markey. "In the past, the NRC adopted a 'see no evil, hear no evil' approach to protecting members of the public from exposure to the radioactive iodine used to treat many cancer patients.""

"A plan awaiting approval by the U.S. Environmental Protection Agency that would dramatically increase permissible radioactive releases in drinking water, food and soil after "radiological incidents" is drawing vigorous objections from agency experts, according to agency documents released today by Public Employees for Environmental Responsibility (PEER). At issue is the acceptable level of public health risk following a radiation release, whether an accidental spill or a "dirty bomb" attack. The radiation arm of EPA, called the Office of Radiation and Indoor Air (ORIA), has prepared an update of the 1992 "Protective Action Guides" (PAG) governing radiation protection decisions for both short-term and long-term cleanup standards. Other divisions within EPA contend the ORIA plan geometrically raises allowable exposure to the public. For example, as Charles Openchowski of EPA's Office of General Counsel wrote in a January 23, 2009 e-mail to ORIA:"

"For the past 20 years, the Nuclear Regulatory Commission has used an epidemiologically invalid study to reassure the public that the continuous release of radioactive material from power plants into the surrounding regions did not contribute to increases in cancer. To correct that unsubstantiated claim, the NRC has contracted with the National Academy of Sciences to conduct a two-year study of both cancer incidence and mortality around former, current, and proposed nuclear reactor sites. The $5 million study, which is expected to take a year to design and two more years to complete, would be the first, comprehensive, government study of the health implications of the continuous release of radioactive into the air and water around nuclear facilities. It would replace the 1990 study conducted for the NRC by the National Institutes of Health - National Cancer Institute titled "Cancer in Populations Living Near Nuclear Facilities." That study concluded that the continuous release of radioactive gas, liquids, and particles - both intentionally and accidentally - did not contribute to the cancer mortality rates in the counties surrounding the 62 reactor sites housing 107 reactors. From an epidemiological standpoint, that study was flawed in its conception and implementation, and hampered by a dearth of data."

"On the surface, the United States pretended it didn't care when the Democratic Party of Japan-led government released documents on a secret pact that allowed the U.S. military to bring nuclear weapons into Japan. Secretly, before the documents were released in March 2010, U.S. officials raised concerns that Washington's global strategy of nuclear arms deterrence would be compromised by the disclosure. The Asahi Shimbun obtained about 7,000 diplomatic cables dated between 2006 and February 2010 from WikiLeaks and analyzed those related to the release of documents surrounding the secret pact. "

"The radiation effects from the Fukushima I nuclear accidents are the results of release of radioactive isotopes from the Fukushima Daiichi Nuclear Power Plant after the 2011 Tōhoku earthquake and tsunami. The total amount of iodine-131 and caesium-137 released into the atmosphere has been estimated to exceed 10% of the emissions from the Chernobyl accident.[1][2] Large amounts on radioactive isotopes have also been released into the Pacific Ocean. The accidents were rated at level 7 rating on the International Nuclear Event Scale."

Beyond Nuclear issued a press release today stating that it and "close to 100" other anti-nuclear or activist groups opposed to nuclear energy are lining up against the nomination of William Magwood to the NRC. Meanwhile, the Nuclear Energy Institute issued a release saying the industry welcomed the nomination of Magwood and George Apostolakis to the Nuclear Regulatory Commission. In a statement, Kevin Kamps of Beyond Nuclear said: "We urged President Obama to instead nominate a strong regulator to the NRC Commission who has demonstrated a commitment to public safety, rather than to nuclear power industry promotional and financial interests. Mr. Magwood has a long track record promoting the nuclear industry's interest, including the scientifically-flawed Yucca Mountain dumpsite proposal, canceled by President Obama."

A rapid-fire exchange of press releases this week Friday, Nov 13 made short order of a claim [press release] by Friends of the Earth (FOE) and the Union of Concerned Scientists (UCS) that the end of testing of MOX fuel in a Duke Power reactor is a "huge setback" to the program. Identical letters sent Nov 10 by Tom Clements representing both two green organizations to Energy Sec. Steven Chu and NRC Chairman Gregory Jaczko claimed that a decision by Duke not to reload test bundles of MOX fuel at the Catawba reactor represents a "failure to demonstrate" the safety of the fuel in a conventional light water reactor. The letter called the situation "an aborted test" and claimed that as a result the MOX fuel is unsafe for use in civilian nuclear reactors. The remainder of the letter is incendiary with claims that the MOX fuel program should not proceed as a result of the "decision" by Duke Energy.

he U.S. Environmental Protection Agency wants the help of former workers at the Santa Susana Field Laboratory to identify contamination from nuclear and radiological projects at the site. The EPA is interested in interviewing former workers for three companies-Atomics International, Rocketdyne and Rockwell-who may know about spills, dumping or other releases of radiological material, the agency said in a news release this week. The lab was established in 1946 and covers nearly 2,900 acres in eastern Ventura County, just west of the San Fernando Valley section of Los Angeles.

As Maryland closes in on the construction of a third reactor at Calvert Cliffs Nuclear Power Plant in Lusby, an environmental organization has released a report calling nuclear power a step backward in the nation's race to reduce pollution. The Environment Maryland Research and Policy Center report, released Tuesday, calls nuclear power "too slow and too expensive," an energy source that makes little economic sense in combating climate change. While nuclear power might be preferable to fossil fuel-based energy sources, it is "diverting and delaying action," said economist John Howley, who was part of a panel convened by Environment Maryland.

Responding to the fears expressed by residents and lawmakers of the risk posed by nuclear power plants built on earthquake zones, government officials reemphasized the safety of the facilities with a press release this week. The safety of the two reactors near Taipei Basin is guaranteed and the earthquake-resistant design is solid, said the Cabinet-level Atomic Energy Council (AEC) in the release. In response to local media reports and legislators' concerns that the first and second nuclear power plants in north Taiwan threaten the region, the council reaffirmed that the earthquake-resistant designs can withstand nearly eight times the strength of the 7.3-magnitude earthquake that struck Taiwan a decade ago on Sept. 21, claiming more than 2,400 lives.

Here is your word for the day: Fracking or fraccing. [No, fellow Battlestar Galactica fans, this is a different use of the word "frack," although for some, the sentiment is the same.] Hydraulic fracturing, or fracking, is a technique that releases natural gas trapped in underground shale formations by injecting water, chemicals, and sand to "frack" the rock structures and release the gas. Often, large quantities of groundwater contaminated by chemicals, radioactive elements, or other minerals are produced in the process. Unless great care is taken, this "produced water" mixed with water used for fracturing can flow to the surface or into groundwater systems and contaminate land, drinking water supplies, and natural waterways.

Valve Leak Stopped, No Radioactive Release Reported At Beaver Valley SHIPPINGPORT, Pa. -- A leak in a valve at a nuclear reactor in Shippingport, Beaver County, has been resolved and no radioactive release was reported. The leak in the Beaver Valley Power Station's No. 2 nuclear reactor was discovered at about 3 a.m. Tuesday. It was resolved within an hour. The Nuclear Regulatory Commission declared the incident an "unusual event," the least of four emergency classifications. A spokesman for the NRC told Channel 4 Action News that the plant has been shut down for maintenance since October, and a valve was accidentally left open while the cooling system was being taken out of service, which caused water to flow into the pressurized relief tank.
