Japan Nuclear Disaster Caps Decades of Faked Reports, Accidents

Bloomberg reports Japan Nuclear Disaster Caps Decades of Faked Reports, Accidents. To me this is one of the scariest articles I've read. Same as the financial crisis, poor regulation and inspection is a significant factor. The whole article is worth a read, but here are some outtakes.

"The destruction caused by last week’s 9.0 earthquake and tsunami comes less than four years after a 6.8 quake shut the world’s biggest atomic plant, also run by Tokyo Electric Power Co. In 2002 and 2007, revelations the utility had faked repair records forced the resignation of the company’s chairman and president, and a three-week shutdown of all 17 of its reactors."

"The cascade of events at Fukushima had been foretold in a report published in the U.S. two decades ago. The 1990 report by the U.S. Nuclear Regulatory Commission, an independent agency responsible for safety at the country’s power plants, identified earthquake-induced diesel generator failure and power outage leading to failure of cooling systems as one of the “most likely causes” of nuclear accidents from an external event. While the report was cited in a 2004 statement by Japan’s Nuclear and Industrial Safety Agency, it seems adequate measures to address the risk were not taken by Tokyo Electric, said Jun Tateno, a former researcher at the Japan Atomic Energy Agency and professor at Chuo University."

"Mitsuhiko Tanaka, 67, working as an engineer at Babcock Hitachi K.K., helped design and supervise the manufacture of a $250 million steel pressure vessel for Tokyo Electric in 1975. Today, that vessel holds the fuel rods in the core of the No. 4 reactor at Fukushima’s Dai-Ichi plant, hit by explosion and fire after the tsunami. Tanaka says the vessel was damaged in the production process. He says he knows because he orchestrated the cover-up. When he brought his accusations to the government more than a decade later, he was ignored, he says."

"“I saved the company billions of yen,” Tanaka said in an interview March 12, the day after the earthquake. Tanaka says he got a 3 million yen bonus ($38,000) from Hitachi and a plaque acknowledging his “extraordinary” effort in 1974. “At the time, I felt like a hero.” That changed with Chernobyl. Two years after the world’s worst nuclear accident, Tanaka went to the Ministry of Economy, Trade and Industry to report the cover-up he’d engineered more than a decade earlier. Hitachi denied his accusation and the government refused to investigate."

"Tokyo Electric in 2002 admitted it had falsified repair reports at nuclear plants for more than two decades. Chairman Hiroshi Araki and President Nobuyama Minami resigned to take responsibility for hundred of occasions on which the company had submitted false data to the regulator. Then in 2007, the utility said it hadn’t come entirely clean five years earlier. It had concealed at least six emergency stoppages at its Fukushima Dai-Ichi power station and a “critical” reaction at the plant’s No. 3 unit that lasted for seven hours."

"The Fukushima Dai-Ichi plant was only designed to withstand a 5.7-meter tsunami, not the 7-meter wall of water generated by last week’s earthquake or the 6.4-meter tsunami that struck neighboring Miyagi prefecture after the Valdiva earthquake in 1960, Ito said. The dangers posed by a tsunami the size of the one generated by the 9.5-magnitude Valdiva temblor off Chile are described in a 2002 report by the Japan Society of Civil Engineers, Ito said. “Tokyo Electric brought this upon itself,” said Ito, who now heads the National Center for the Citizens’ Movement Against the Nuclear Threat, based in Tokyo. “This accident unfolded as expected.”"

"Kansai Electric Power Co., the utility that provides Osaka with electricity, said it also faked nuclear safety records. Chubu Electric Power Co., Tohoku Electric Power Co. and Hokuriku Electric Power Co. (9505) said the same."

"After Hokuriku Electric’s Shika nuclear power plant in Ishikawa prefecture was rocked by a 6.9 magnitude quake in March 2007, government scientists found it had been built near an earthquake fault that was more than twice as long as regulators deemed threatening. “Regulators just rubber-stamp the utilities’ reports,” Takashi Nakata, a former Hiroshima Institute of Technology seismologist and an anti-nuclear activist, said at the time."

"While Japan had never suffered a failure comparable to Chernobyl, the Fukushima disaster caps a decade of fatal accidents. Two workers at a fuel processing plant were killed by radiation exposure in 1999, when they used buckets, instead of the prescribed containers, to eye-ball a uranium mixture, triggering a chain-reaction that went unchecked for 20 hours."

"In 2004, an eruption of super-heated steam from a burst pipe at a reactor run by Kansai Electric killed five workers and scalded six others. A government investigation showed the burst pipe section had been omitted from safety checklists and had not been inspected for the 28 years the plant had been in operation."

And here's a significant point that will probably be lost in a lot of cable and network news reports. "Unlike France and the U.S., which have independent regulators, responsibility for keeping Japan’s reactors safe rests with the same body that oversees the effort to increase nuclear power generation: the Trade Ministry. Critics say that creates a conflict of interest that may hamper safety."

Not just in Japan, but radioactive contamination should be measure any where in the world where there are nuclear power plants. US is the countries with most nuclear power plants, there should be some measurement there as well.
