    The operator of the Fukushima Daiichi nuclear power station says 3 of the plant's 6 reactors were shaken on March 11th by tremors exceeding forces they were designed to withstand. The Tokyo Electric Power Company, known as TEPCO, says reactor No.2 suffered the largest horizontal ground acceleration of 550 gals, which is 26 percent stronger than the reactor's design limit. TEPCO says the readings were 548 gals at the No.5 reactor, about 21 percent higher than its design limit; and 507 gals at the No.3 reactor, topping the capacity by about 15 percent. The power company says the strength of...

    A U.S. simulation exercise conducted about 30 years ago of what would happen at a boiling-water reactor if all power sources were lost eerily matches what has unfolded at the Fukushima No. 1 nuclear power plant. While the simulation demonstrated the dangers of losing all power sources, Japan's nuclear authorities took the optimistic position that power transmission lines and other power sources would be restored quickly. The simulation was conducted by the Oak Ridge National Laboratory in 1981 and 1982. A report was later submitted to the U.S. Nuclear Regulatory Commission, which used the report's findings to establish safety regulations....

    The mayor of Minamisoma, Fukushima Prefecture, a city subject to a government directive for its residents to stay indoors to avoid radioactive fallout from a nuclear plant crippled by the March 11 earthquake and tsunami, has begun appealing to the world over the ''injustice'' of such an instruction. Speaking in a roughly 11-minute English-subtitled video posted on the video-sharing site Youtube on March 24, Katsunobu Sakurai said the government's directive has made life extremely difficult for local residents. ''Even volunteers and those delivering relief supplies have no choice but to enter (the city) at their own risk,'' said a grim-looking...

    TOKYO – In planning their defense against a killer tsunami, the people running Japan's now-hobbled nuclear power plant dismissed important scientific evidence and all but disregarded 3,000 years of geological history, an Associated Press investigation shows. The misplaced confidence displayed by Tokyo Electric Power Co. was prompted by a series of overly optimistic assumptions that concluded the Earth couldn't possibly release the level of fury it did two weeks ago, pushing the six-reactor Fukushima Dai-ichi complex to the brink of multiple meltdowns. Instead of the reactors staying dry, as contemplated under the power company's worst-case scenario, the plant was overrun...

    Radiation risk nothing like Chernobyl, expert says The U.S. government may have overreacted in setting an 80-km radius no-go zone for U.S. citizens near the Fukushima No. 1 power plant, an expert on radiation and cancer immunology said Tuesday in Tokyo. U.S. hematologist Robert Gale, who treated Chernobyl exposure victims in 1986, said the current exclusion zone by the Japanese government that covers a 20-km radius around the plant is already "conservative." "There is no solid reason for the U.S. government to suggest a wider evacuation," considering the current level of microsieverts detected in the region, he said. Gale was...

    Plant operators evacuated workers from Japan's tsunami-stricken nuclear complex Monday after gray smoke rose from one of its reactor units, the latest of persistent troubles in stabilizing the complex after it was damaged in a quake and tsunami. Smoke rising from the spent fuel storage pool of the plant's Unit 3 prompted the evacuation, Tokyo Electric Power Co. spokesman Hiroshi Aizawa said. The problem-plagued Unit 3 also alarmed plant officials over the weekend with a sudden surge of pressure in its reactor core.

    Engineers had run a power line to the Fukushima Daiichi plant, 150 miles north of Tokyo, from the country's electrical grid Friday night, but connecting it to the buildings at the facility has been a bigger problem than anticipated. Workers have been able to spend only limited amounts of time in the facility to make the connections, and engineers have had to laboriously go through and check all the circuitry before power is turned on to ensure that a surge of current does not create more problems than it solves. Officials of the company had said they hoped to get...

    Japan’s turbulent history of war and natural catastrophe has already given the world a terrifying vocabulary of death: tsunami, kamikaze, Hiroshima. But the country now stands on the brink of unleashing its most chilling phrase yet: genpatsu-shinsai – the combination of an earthquake and nuclear meltdown capable of destroying millions of lives and bringing a nation to its knees. The phrase, derived from the Japanese words for “nuclear power” and “quake disaster”, is the creation of Katsuhiko Ishibashi, Japan’s leading seismologist and one of the Government’s top advisers on nuclear-quake safety.

    In Stricken Fuel-Cooling Pools, a Danger for the Longer Term By WILLIAM J. BROAD and HIROKO TABUCHI Published: March 14, 2011 Even as workers race to prevent the radioactive cores of the damaged nuclear reactors in Japan from melting down, concerns are growing that nearby pools holding spent fuel rods could pose an even greater danger. The pools, which sit on the top level of the reactor buildings and keep spent fuel submerged in water, have lost their cooling systems and the Japanese have been unable to take emergency steps because of the multiplying crises. The threat is that the...

    Seismologist Ishibashi Katsuhiko claimed that an accident was likely and that plants have 'fundamental vulnerability' The timing of the near nuclear disaster at Fukushima Daiichi could not have been more appropriate. In only a few weeks the world will mark the 25th anniversary of the worst nuclear plant disaster ever to affect our planet – at Chernobyl in Ukraine. A major core meltdown released a deadly cloud of radioactive material over Europe and gave the name Chernobyl a terrible resonance. This weekend it is clear that the name Fukushima came perilously close to achieving a similar notoriety. However, the real...

The 6.8 magnitude temblor of July 16 caused considerable damage to the Kashiwazaki-Kariwa Nuclear Power plant operated by Tokyo Electric Power Co. (TEPCO), proving me right. In the 40 years that Japan had been building nuclear plants, seismic activity was, fortunately or unfortunately, relatively quiet. Not a single nuclear facility was struck by a big quake.

Tokyo Electric said it was trying to figure out how to maintain water levels in the pools, indicating that the normal safety systems there had failed, too. Failure to keep adequate water levels in a pool would lead to a catastrophic fire, said nuclear experts, some of whom think that unit 1’s pool may now be outside.

It is premature to draw conclusions from the tragedy in Japan about the U.S. nuclear energy program. Japan is facing what literally can be considered a “worst case” disaster and, so far, even the most seriously damaged of its 54 reactors has not released radiation at levels that would harm the public. That is a testament to their rugged design and construction, and the effectiveness of their employees and the industry’s emergency...

Sunday, Japan's largest electric utility started releasing steam at a second troubled nuclear reactor container vessel, Unit 3, at its Fukushima Daiichi power plant. The Nuclear and Industrial Safety Agency earlier reported that the cooling system malfunctioned at Unit 3. The agency said it was informed of the emergency by Tokyo Electric Co., or TEPCO,...

    I just watched CNN’s “Reliable Sources” backpedaling furiously on their hype over “Nuclear Meltdown” & “Explosion at Nuclear Plant” One CNN reporter just said “We have been extremely irresponsible in our (doom & gloom) reporting.” “We need to cut back on the ‘heavy music’” and “we rushed to keep up with the 24 hour news schedule”. Can any Freeper out there capture the video & post it?

    Health risks from Japan's quake-hit nuclear power reactors seem fairly low and winds are likely to carry any contamination out to the Pacific without threatening other nations, experts say. Tokyo battled to avert a meltdown at three stricken reactors at the Fukushima plant in the worst nuclear accident since the 1986 Chernobyl disaster, triggered by Friday's tsunami. Radiation levels were also up at the Onagawa atomic plant. "This is not a serious public health issue at the moment," Malcolm Crick, Secretary of the U.N. Scientific Committee on the Effects of Atomic Radiation, told Reuters. "It won't be anything like Chernobyl....

    Status of water injection Injection of fresh water mixed with boron to inhibit nuclear reactions was started as soon as venting had been completed. However, water levels continued to fall and Tepco began an operation to inject seawater into the reactor vessel. In a media briefing at 8.00pm, chief cabinet secretary Yukio Edano stated that while initially the water level had risen, a gauge indicated that this had leveled off, despite ongoing seawater injection. The Japan Atomic Industry Forum (JAIF) said that a malfunctioning guage means that water levels cannot be confirmed. Meanwhile, pressure in unit 3 has been gradually...
  • Japan radiation unlikely to reach US: officials (the federal Nuclear Regulatory Commission (NRC))

    WASHINGTON (AFP) – Radiation from nuclear plants damaged in Japan's earthquake is unlikely to reach US territory in harmful amounts, US nuclear officials said Sunday. "Given the thousands of miles between the two countries, Hawaii, Alaska, the US Territories and the US west coast are not expected to experience any harmful levels of radioactivity," the federal Nuclear Regulatory Commission (NRC) said in a statement. "All the available information indicates weather conditions have taken the small releases from the Fukushima reactors out to sea away from the population," the statement read. The office also said it sent two boiling-water reactor experts...

    American Nuclear Society Backgrounder: Japanese Earthquake/Tsunami; Problems with Nuclear Reactors 3/12/2011 5:22 PM EST To begin, a sense of perspective is neededÂ… right now, the Japanese earthquake/tsunami is clearly a catastrophe; the situation at impacted nuclear reactors is, in the words of IAEA, an "Accident with Local Consequences." The Japanese earthquake and tsunami are natural catastrophes of historic proportions. The death toll is likely to be in the thousands. While the information is still not complete at this time, the tragic loss of life and destruction caused by the earthquake and tsunami will likely dwarf the damage caused by the...

    I am writing this text (Mar 12) to give you some peace of mind regarding some of the troubles in Japan, that is the safety of Japan’s nuclear reactors. Up front, the situation is serious, but under control. And this text is long! But you will know more about nuclear power plants after reading it than all journalists on this planet put together. There was and will *not* be any significant release of radioactivity. By “significant” I mean a level of radiation of more than what you would receive on – say – a long distance flight, or drinking a...

    I know this is a fairly full on statement from someone posting his very first blog. It will also be far and away the most well written, intelligent post I ever make (I hope!) It also means I am not responsible for its content. This post is by Dr Josef Oehmen, a research scientist at MIT, in Boston. He is a PhD Scientist, whose father has extensive experience in Germany’s nuclear industry. I asked him to write this information to my family in Australia, who were being made sick with worry by the media reports coming from Japan. I am...
