The area in pink indicates the location of the roof collapse. It is about 50 meters (165 feet) away from the "sarcophagus," a shelter built shortly after the 1986 disaster to contain radiation emanating from the exploded reactor. A 6,500 square foot section of roof on the turbine hall at Chernobyl collapsed last week due to heavy snow. Russia/Ukraine/ex-USSR - Chernobyl roof collapse worries activists
By World Nuclear News -- (October 21, 2012) Areva is to fit all 23 Japanese pressurized water reactors with hydrogen recombiners that help to prevent the explosive gas building up in emergency situations.

In his will Albert Einstein ordered that his secretary Helen Dukas (1896-1982) and Dr. Otto Nathan (German-American economist, 1893-1987) should take care of his literary assets during their lifetime. Thereafter his literary assets should belong to the Hebrew University in Jerusalem. At the time of his death Einstein’s written heritage comprised about 14,000 documents. Through the great engagement and thanks to the untiring commitment of Helen Dukas and Dr. Albert Einstein Archives in Jerusalem
Omaha Public Power District (OPPD) has announced an operating services agreement with Exelon Generation, LLC for the management of Fort Calhoun’s nuclear operations for up to the duration of its operating licence, which is due to expire in September 2033. Under the agreement, OPPD will remain the owner and licensed operator of the plant, while Exelon will provide the day-to-day operations management. The Exelon Nuclear Management Model will be used to improve and sustain performance at Fort Calhoun Station. The model is a systematic, formal, detailed guide to every aspect of safe nuclear plant operations. The plant staff will be a blended team of OPPD and Exelon employees.

Fukushima Meltdown Hastens Decline of Nuclear Power
Nuclear accidents likely 'every ten to twenty years' Catastrophic nuclear accidents such as the core meltdowns at Chernobyl and Fukushima are 200 times more likely to happen than previously believed, say scientists. Based on the operating hours of all civil nuclear reactors and the number of nuclear meltdowns that have occurred in the past, a team at the Max Planck Institute for Chemistry in Mainz has calculated that such accidents could occur once every 10 to 20 years. And, they say, when they do, half of the radioactive caesium-137 would spread more than 1,000 kilometers, and a quarter more than 2,000 kilometers. Western Europe would receive a dosage of more than 40 kilobecquerel of caesium-137 per square meter - the International Atomic Energy Agency official contamination level - about once every 50 years. In light of the results, the researchers are calling for an in-depth analysis and reassessment of the risks associated with nuclear power plants. Currently, there are 440 nuclear reactors in operation, and 60 more are planned.
Nuclear meltdowns 200x more likely than previously estimated Catastrophic nuclear accidents such as the core meltdowns in Chernobyl and Fukushima are more likely to happen than previously assumed. Based on the operating hours of all civil nuclear reactors and the number of nuclear meltdowns that have occurred, scientists at the Max Planck Institute for Chemistry in Mainz have calculated that such events may occur once every 10 to 20 years (based on the current number of reactors) — some 200 times more often than estimated in the past. The researchers also determined that, in the event of such a major accident, half of the radioactive caesium-137 would be spread over an area of more than 1,000 kilometres away from the nuclear reactor. Their results show that Western Europe is likely to be contaminated about once in 50 years by more than 40 kilobecquerel of caesium-137 per square meter. According to the International Atomic Energy Agency, an area is defined as being contaminated with radiation from this amount onwards.

More than a year after a tsunami swamped the Fukushima-Daiichi nuclear power plants, the radiation peril continues -- reactor 4 is teetering on the edge of collapse, which would force the evacuation of one-third of Japan's population. The meltdown at Fukushima parallels the meltdown of the US economy. On March 11, 2011, Japan experienced a 9.0 earthquake. Bob Burnett: Two Meltdowns: Fukushima and the US Economy
U.S. Nuclear Regulatory Commission Chairman Gregory Jaczko said he is resigning, as lawmakers, colleagues and an independent watchdog criticize what they said is a bullying style and mistreatment of female employees. “This is the appropriate time to continue my efforts to ensure public safety in a different forum,” Jaczko said today in a statement. “My responsibility and commitment to safety will continue to be my paramount priority after I leave the commission and until my successor is confirmed.” In an interview, he said disputes with NRC colleagues weren’t a reason for his decision. Jaczko, 41, whose term expires in June 2013, has been faulted for his management by other commissioners and in a report by the agency inspector general last year.

IAEA Says Fukushima Daiichi Power Plant Suffered A Meltdown | Newsroom Magazine USA Edition
The human cost of the Fukushima meltdowns, one year later Well, I guess this will all serve as a spur for Japan to invest even more money in alternatives like geothermal, wind and solar--which actually they've been heavily investing in for many decades now. I don't think Japan will ever be able to totally abandon nuclear energy despite the current outcrys in the country to do just that. Given the long history of earthquakes and vulcanism in Japan, there really aren't that many totally stable places to build new reactors. New reactors must be designed to expect some kind of earthquake related disaster to happen at some point. But really, the long term thing to learn here? All old nuclear power planets must be constantly rebuilt and refurbished with new technology to keep them safe when every new disaster teaches us something new.
As Japan and the world prepare for tomorrow's one-year anniversary of the Fukushima disaster, government documents have been released revealing that top Japanese officials were directly warned of an imminent meltdown at the Nuclear plant but failed to take action and denied any such risks to the public. The report confirms suspicions of deceit in the government's handling of the disaster. International Atomic Energy Agency (IAEA) experts and TEPCO staff stand near Unit 3 , Fukushima Dai-ichi nuclear complex (AP / Tokyo Electric Power Co.) Agence France-Presse reports : A summary of a government meeting held about four hours after a giant earthquake sent huge waves crashing into the atomic power station showed that one unidentified participant had cautioned of the risk of a meltdown. “If the temperature of the reactor cores rises after eight hours, there is a possibility that a meltdown will occur,” the person said, according to the summary released on Friday.

by Huw Griffith TOKYO, March 10, 2012 (AFP) - Japan was Saturday preparing to mark the first anniversary of its tsunami, as government papers revealed ministers were warned of the possibility of meltdowns at Fukushima just after the waves struck. A summary of a government meeting held about four hours after a giant earthquake sent a wall of water crashing into the atomic power station showed that one unidentified participant had cautioned of the risk of a meltdown. "If the temperature of the reactor cores rises after eight hours, there is a possibility that a meltdown will occur," the person said, according to the summary released on Friday.

TEPCO sued over Fukushima meltdown - World Updated Tue Mar 6, 2012 10:04am AEDT A group of shareholders is suing former and current directors of the Tokyo Electric Power Company (TEPCO) for more than $60 billion over the Fukushima nuclear meltdowns. The 42 TEPCO shareholders say the company knew from modelling estimates that a tsunami of more than 15 metres in height could strike the Fukushima nuclear plant. But they say the company ignored the estimates and did nothing to raise the breakwater protecting the plant. They are seeking to have 27 former and current TEPCO directors pay $62 billion in damages, in what could be the largest civil damages suit in Japanese history. The shareholders say if successful they will ask the company to use the money to help victims of the meltdowns.
