Designer of Reactor No. 4 suspects Tepco cooked up simulation in attempt to deceive public
Real cause of nuclear crisis, Japan Times (abridged translation of an article from the December issue of Sentaku), Dec. 12, 2011 (Emphasis Added):
Science journalist Mitsuhiko Tanaka, formerly with Babcock-Hitachi K.K. as an engineer responsible for designing the pressure vessel for Fukushima Daiichi Reactor No. 4
- Tepco said that according to its simulation, the meltdown at the No. 1 reactor of the nuclear power plant happened about 15 hours after the earthquake
- Tanaka says that the simulation is far different from the actually measured water level and pressure
- Although the simulation report says that the pressure […] shot up to more than seven times […] about 15 hours after the quake
- The fact is that the pressure had already risen to six times […] five to six hours before the time given by the simulation report
- Simulation data calculated by a computer can be manipulated easily depending on the types of input
- Tanaka suspects that Tepco cooked up simulation results to suit its own purposes in an attempt to deceive the public

Fukushima gov’t estimates radiation exposure of up to 19 millisieverts
FUKUSHIMA (Kyodo) — Residents near the crisis-hit Fukushima Daiichi nuclear power plant may have been exposed to up to 19 millisieverts of radiation in the four months after the plant was crippled by the March 11 earthquake and tsunami, the Fukushima prefectural government said Tuesday.
The local government released its estimates of residents’ radiation exposure in 12 municipalities near the power plant — Namie, Kawamata, Iitate, Futaba, Okuma, Minamisoma, Tamura, Tomioka, Naraha, Hirono, Katsurao and Kawauchi. The plant is located in the towns of Futaba and Okuma.
Residents who evacuated from high-risk areas in the village of Iitate in late June may have been exposed to the highest amount of 19 millisieverts, it said.
Shunichi Yamashita, vice president of the prefectural government-run Fukushima Medical University, told a news conference that the level is low compared with the 1986 Chernobyl nuclear disaster in the then Soviet republic of Ukraine. “I think there is no problem,” Yamashita said.

Fukushima releases radiation checkup results
The prefecture has been checking the health of its nearly 2-million residents, focusing on estimates of their external radiation exposure during the 4 months since the accident at the Fukushima Daiichi nuclear plant.
On Tuesday, the prefecture released the results for 1,727 people in Namie Town, Iitate Village and a district in Kawamata Town. The municipalities are 10 to 50 kilometers from the plant.
Fukushima says 1,675, or 97 percent, of the people are thought to have been exposed to less than 5 millisieverts of radiation. 1,084 people are thought to have been exposed to less than one millisievert — the government’s safety limit for one year.
Nine people are thought to have been exposed to 10 millisieverts or more. Five of them are nuclear plant workers, among whom the highest level was 37 millisieverts. Of other 4, one who repeatedly visited an evacuation zone was exposed to 14 millisieverts.
Fukushima Medical University Vice President Shunichi Yamashita says the results show that exposure levels of most people were lower than a standard that would require evacuation, with extremely low health impact.

Fishermen’s OK needed to dump nuclear plant water into sea: Edano
TOKYO (Kyodo) — Japanese industry minister Yukio Edano on Tuesday called into question the Fukushima Daiichi nuclear power plant operator’s plan to release low-level radioactive water into the Pacific Ocean, saying doing so without consent from fishermen should not be allowed.
“It should not be socially allowed that (the operator) goes ahead (with the plan) before gaining agreement from people involved in the fishery industry,” Edano said at a press conference.
Tokyo Electric Power Co. said earlier this month it is considering releasing into the Pacific Ocean low-level radioactive water now stored in tanks at the premises of its crippled Fukushima Daiichi nuclear power plant, as storage capacity may run short by next March.
The utility known as TEPCO said the water would be released only after it clears the country’s legal concentration limit for radioactive substances, including strontium, but domestic fisheries cooperatives fiercely oppose the plan.
Edano’s remark effectively makes it necessary for TEPCO to gain consent from the fishery industry for its release of the power plant’s treated water into the sea.

Fire under control at Tsuruga nuclear plant
A fire at the Tsuruga nuclear power plant in Fukui Prefecture, central Japan, has been brought under control. There are no reports of radioactive materials having leaked to nearby areas.
Japan Atomic Power Company, the plant operator, says the blaze broke out at 7:45 PM on Monday. A worker had turned on a switch for a spare electrical device located at a water processing facility in the No. 1 reactor.
Workers at the plant managed to put out the fire. No one was injured.
JAPC says there is no radiation leak because the reactor had been closed for inspection.
The plant operator says there was a short circuit, and the fire may have been caused by sparks.
The cables were brought in to replace the regular power supply system, which is scheduled for inspection, with an auxiliary power source.
Three other fires have broken out at the plant between March 2010 and October 2011, when workers were welding or using gas burners for maintenance.
JAPC had submitted reports on fire prevention and safety measures to avoid this kind of accident on November 30th.

All preconditions to declare cold shutdown met
Japan’s nuclear watchdog has approved measures that will be implemented over the next 3 years to ensure stability at the troubled Fukushima Daiichi Nuclear Power Plant.
Tokyo Electric Power Company’s mid-term safety procedures include ways to further cool the damaged reactors, and to prevent possible hydrogen explosions at the plant. TEPCO plans to implement the steps over the next 3 years to achieve the second phase of the time table to put the plant under control.
At a meeting of the Nuclear Safety Commission on Monday, some participants pointed out that the reactors have yet to reach a stable state, and that possibilities of fresh problems remain.
Others called on the utility to monitor the durability of the equipment and facilities it is using to manage the disaster. But the members ultimately approved the safety measures planned by TEPCO.
After the decision, commission chief Haruki Madarame said the utility should implement the measures as soon as possible, as it is difficult to accurately predict what may yet happen in the damaged reactors.
The Japanese government is expected to declare later this week that a state of cold shutdown has been achieved for all the plant’s reactors. The government hopes the declaration will lead to a review of current evacuation areas.

Japanese Engineer: “There Was a Nuclear Explosion in Reactor 3 in Addition to a Hydrogen Explosion”
There are foreign nuclear experts who have said the explosion in Reactor 3 on March 14 at Fukushima I Nuclear Power Plant was a nuclear explosion. But this Japanese engineer and whistleblower at JNES (Japan Nuclear Energy Safety Organization) Setsuo Fujiwara says there were two explosions at Reactor 3: a hydrogen explosion, and a nuclear explosion at the Spent Fuel Pool.

Huffington Post: ” NRC ‘Coup’ Leader, Bill Magwood, Consulted For Fukushima Parent Company”
Bio of Bill Magwood at the NRC site is here.
From Huffington Post (12/12/2011):
WASHINGTON — Bill Magwood, the man at the center of an effort to overthrow the chairman of the Nuclear Regulatory Commission and his most likely successor if the move is successful, served as a consultant for Tepco, the Japanese company that owns the Fukushima nuclear power plant, according to information provided by Magwood as part of his nomination and confirmation process, which was obtained by The Huffington Post.
On Friday, Rep. Darrell Issa (R-Calif.) released a letter signed by Magwood and three other commissioners attacking the panel’s chairman, Gregory Jaczko, setting off a firestorm in the energy industry. Issa and the four commissioners framed the dispute as personal and managerial, but emails released by Rep. Ed Markey (D-Mass.) show a political and ideological battle underway over post-Fukushima safety standards.
Issa and Markey appeared opposite one another on MSNBC on Monday, continuing to debate whether the issue is one of personality or the politics of nuclear safety. Magwood’s previously unreported relationship to Japan’s nuclear industry, via the firm he founded and ran, Advanced Energy Strategies, sheds new light on that debate.

Fire And Water At Japanese Nuclear Power Plants
Posted: December 13, 2011 i
Not a day passes without news of fires and water leaks in various nuclear power plants in Japan: after Fukushima, Genkai, Mihama leaks last week (these are geographically as far as can be from each other in Japan), it is the turn of Tsuruga in Fukui prefecture to be on fire (again). Tsuruga is, along with other troubled Mihama and Monju reactors, situated on “Nuclear Ginza” coast of the Sea of Japan in Honshu, close enough to cities like Nagoya and Kyoto to cause a disaster in case of accident.
