Earthquakes are routinely measured by magnitude, or energy released. But the Nuclear Regulatory Commission (NRC)requires the nation's 104 nuclear reactors to withstand a predicted level of ground motion, or acceleration — something called g-force. What does that mean, magnitude-wise?

"I don't have what that translates into … unfortunately," NRC spokesman David McIntyre says. The agency released a statement Thursday to clarify its "earthquake measurements and design criteria," but it does not say what ground motion each reactor can handle. This muddiness heightens the concerns of industry critics, who have urged stricter safety rules after reactors at Japan's Fukushima Dai-ichi nuclear plant nearly melted down due to a magnitude-9.0 earthquake and tsunami on March 11.

A task force mandated by President Obama recommended in July that each U.S. plant be re-examined, given ongoing NRC research that shows the seismic risks for Eastern and Central U.S. nuclear power plants have increased. "The Virginia earthquake is now our local 911 call to stop delaying the implementation of stricter safety standards," Rep. Edward Markey, D-Mass., wrote in a letter this week to the NRC.

UPDATE* EX-SKF has a translation of Tepco’s press release: Fukushima Reactor 4 Skimmer Surge Tank Latest: Earthquake Caused the Water to Go from SFP to Reactor Well Instead, Says TEPCO “Tepco officially admitted the decreasing water level of the tank at reactor 4 was caused by the earthquake on 1/1/2012. (Source) Tepco states the water did not flow into the tank from water cooling system but flew into the container vessel in stead. However they still have not announced they managed to fixed the broken part of the reactor.” -Fukushima Diary Mainichi Shimbun, January 2, 2012:

Google Translate Headline: <1 Fukushima nuclear power plant> No. 4 tank drawdown effects of earthquakes and announced …

TEPCO two days, the water level decreased by more than one day of the tank adjacent to the spent fuel pool of the first nuclear power plant Unit 4, Fukushima, said the cause, effects of earthquakes announced four largest intensity observed in northeastern Kanto was. TEPCO, flows into the opposite side of the reactor containment tank of radioactive contamination in pool water, and found that it caused by loss of water supply to the tank from a temporary pool. The cooling effect of the pool, he said. According to TEPCO, the tank water level is usually about 1.6 inches per hour, such as reduced natural evaporation, after the earthquake, were down by 8-9 cm per hour. Polluted water in the tank is removed from heat and dust through the filter and an external heat exchanger and returned to the pool again.

As Canadians learned about dangerous radiation falling on them in rain on Tuesday as far east as Toronto registered at 20,000 CPM, equivalent to the highly targeted dose of radiation for cancer radiotherapy,  the Fukushima catastrophe escalated even higher Wednesday with evidence that the ground is cracking under the crippled nuclear power plant, causing radioactive steam to escape, "very serious and alarming" according to Anissa Naouai's guest on Russia Today, Dr. Robert Jacobs, Professor of nuclear history at Hiroshima Peace Institute. 

Fukushima nuclear plant workers have reported that the ground under the facility is cracking and radioactive steam is already escaping through the cracks that Dr. Jacobs says is very serious and alarming development because it has happened after two large earthquakes over the past few weeks according to Russia Today. (See embedded Russia Today interviewing Dr. Jacobs on Youtube video on this page left.) "There was a 6.4 earthquake on the 31st of July and a 6.0 earthquake on August 12th," Dr. Jacobs told Russia Today's Naoiai.

"What this indicates is there may have been some breaking of the pipes and some of the structures underground that happened during these earthquakes," he said. "There could be radioactive water that is venting into the soil and what's more, as cracks are opening, the steam and radioactivity is working its way up," he said.

WASHINGTON (AP) — The risk that an earthquake would cause a severe accident at a U.S. nuclear plant is greater than previously thought, 24 times as high in one case, according to an AP analysis of preliminary government data. The nation's nuclear regulator believes a quarter of America's reactors may need modifications to make them safer.The threat came into sharp focus last week, when shaking from the largest earthquake to hit Virginia in 117 years appeared to exceed what the North Anna nuclear power plant northwest of Richmond was built to sustain.

The two North Anna reactors are among 27 in the eastern and central U.S. that a preliminary Nuclear Regulatory Commission review has said may need upgrades. That's because those plants are more likely to get hit with an earthquake larger than the one their design was based on. Just how many nuclear power plants are more vulnerable won't be determined until all operators recalculate their own seismic risk based on new assessments by geologists, something the agency plans to request later this year. The NRC on Thursday issued a draft of that request for public comment.

The NRC and the industry say reactors are safe as they are, for now. The average risk to U.S. reactors of core damage from a quake remains low, at one accident every 500 years, according to the AP analysis of NRC data.The overall risk at a typical reactor among the 27 remains very slight. If the NRC's numbers prove correct, that would mean no more than one core accident from an earthquake in about 30,000 years at the typical reactor among the 27 with increased risk.

Residents in the radiation danger zone, instructed to stay inside their homes, are venturing out in search of food and fuel. A Japanese businessman in the country's northeast tells Joan Juliet Buck how government incompetence is killing people who escaped the earthquake.

Writer, cultural critic, and actor Joan Juliet Buck wrote to a foreign-born Japanese friend in the food business to ask him how we in America could help Japan. Below is his answer. Tellingly, he does not want to be identified

“As you are a journalist,” he wrote back, “first I would like to explain how the Japanese government and bureaucrats are incompetent against the crisis.”

SciDev.Net reporters from around the world tell us which countries are set on developing nuclear energy despite the Fukushima accident. The quest for energy independence, rising power needs and a desire for political weight all mean that few developing countries with nuclear ambitions have abandoned them in the light of the Fukushima accident. Jordan's planned nuclear plant is part of a strategy to deal with acute water and energy shortages.

The Jordan Atomic Energy Commission (JAEC) wants Jordan to get 60 per cent of its energy from nuclear by 2035. Currently, obtaining energy from neighbouring Arab countries costs Jordan about a fifth of its gross domestic product. The country is also one of the world's most water-poor nations. Jordan plans to desalinate sea water from the Gulf of Aqaba to the south, then pump it to population centres in Amman, Irbid, and Zarqa, using its nuclear-derived energy. After the Fukushima disaster, Jordan started re-evaluating safety procedures for its nuclear reactor, scheduled to begin construction in 2013. The country also considered more safety procedures for construction and in ongoing geological and environmental investigations.

The government would not reverse its decision to build nuclear reactors in Jordan because of the Fukushima disaster," says Abdel-Halim Wreikat, vice Chairman of the JAEC. "Our plant type is a third-generation pressurised water reactor, and it is safer than the Fukushima boiling water reactor." Wreikat argues that "the nuclear option for Jordan at the moment is better than renewable energy options such as solar and wind, as they are still of high cost." But some Jordanian researchers disagree. "The cost of electricity generated from solar plants comes down each year by about five per cent, while the cost of producing electricity from nuclear power is rising year after year," says Ahmed Al-Salaymeh, director of the Energy Centre at the University of Jordan. He called for more economic feasibility studies of the nuclear option.

Sixteen tons and what you get is a nuclear catastrophe. The explosions that rocked the Fukushima No.1 nuclear plant were more powerful than the combustion of hydrogen gas, as claimed by the Tokyo Electric Power Company. The actual cause of the blasts, according to intelligence sources in Washington, was nuclear fission of. warhead cores illegally taken from America's sole nuclear-weapons assembly facility. Evaporation in the cooling pools used for spent fuel rods led to the detonation of stored weapons-grade plutonium and uranium.   The facts about clandestine American and Israeli support for Japan's nuclear armament are being suppressed in the biggest official cover-up in recent history. The timeline of events indicates the theft from America's strategic arsenal was authorized at the highest level under a three-way deal between the Bush-Cheney team, Prime Minister Shinzo Abe and Elhud Olmert's government in Tel Aviv.

Tokyo's Strangelove   In early 2007, Vice President Dick Cheney flew to Tokyo with his closest aides. Newspaper editorials noted the secrecy surrounding his visit - no press conferences, no handshakes with ordinary folks and, as diplomatic cables suggest, no briefing for U.S. Embassy staffers in Tokyo.   Cheney snubbed Defense Minister Fumio Kyuma, who was shut out of confidential talks. The pretext was his criticism of President George Bush for claiming Iraq possessed weapons of mass destruction. The more immediate concern was that the defense minister might disclose bilateral secrets to the Pentagon. The Joint Chiefs of Staff were sure to oppose White House approval of Japan's nuclear program.

Abe has wide knowledge of esoteric technologies. His first job in the early 1980s was as a manager at Kobe Steel. One of the researchers there was astrophysicist Hideo Murai, who adapted Soviet electromagnetic technology to "cold mold" steel. Murai later became chief scientist for the Aum Shinrikyo sect, which recruited Soviet weapons technicians under the program initiated by Abe's father. After entering government service, Abe was posted to the U.S. branch of JETRO (Japan External Trade Organization). Its New York offices hosted computers used to crack databases at the Pentagon and major defense contractors to pilfer advanced technology. The hacker team was led by Tokyo University's top gamer, who had been recruited into Aum.   After the Tokyo subway gassing in 1995, Abe distanced himself from his father's Frankenstein cult with a publics-relations campaign. Fast forward a dozen years and Abe is at Camp David. After the successful talks with Bush, Abe flew to India to sell Cheney's quadrilateral pact to a Delhi skeptical about a new Cold War. Presumably, Cheney fulfilled his end of the deal. Soon thereafter Hurricane Katrina struck, wiping away the Abe visit from the public memory.

Televisions, fridges and furniture pieces are heading for Hawaii, as a huge amount of debris from Japan’s earthquake sails across the Pacific.Up to 20 million tons of debris from the earthquake in March is traveling faster than expected and could reach the U.S. West Coast in three years.A Russian ship’s crew spotted the debris - which included a 20ft long fishing boat - last month after passing the Midway Islands.

We have a rough estimate of 5 to 20 million tons of debris coming from Japan,’ University of Hawaii researcher Jan Hafner told KITV.Experts have revised predictions to say the debris will now reach the Midway Islands by winter and Hawaii in less than two years.Crew members on the Russian training ship STS Pallada spotted the debris 2,000 miles from Japan, including a fishing boat from Fukushima, reported AFP.‘They saw some pieces of furniture, some appliances, anything that can float - and they picked up a fishing boat,’ Mr Hafner told KITV.A crew member told AFP: 'We keep sighting things like wooden boards, plastic bottles, buoys from fishing nets [small and big ones], an object resembling a wash basin, drums, boots, other wastes.'

His latest book, "Fukushima Meltdown: The World's First Earthquake-Tsunami-Nuclear Disaster," has just become available online as a Kindle book in an excellent and fluid translation by a team under the guidance of American author and scholar, Douglas Lummis. Originally published as "Fukushima Genpatsu Merutodaun" by Asahi Shinsho on May 30, 2011, this is the book that Hirose had hoped he would never have to write. For three decades he has been warning Japanese people about the catastrophes that could been visited on their country — and now his worst nightmare has become a reality. "This is called the '3/11 Disaster' by many," he writes, "but it did not happen on 3/11, it began on 3/11 and it is continuing today. ... Nuclear power plants are a wildly dangerous way to get electricity and are unnecessary. The world needs to learn quickly from Japan's tragedy." Hirose points out that from day one of the disaster the situation in Fukushima had reached the highest level of nuclear accidents, namely level 7 — and from the outset, the government was keenly aware of this fact. But it chose to conceal the truth from the people.

"In past nuclear-plant disasters — those at Chernobyl (in present-day Ukraine, in 1986) and at Three Mile Island (in Pennsylvania in the United States, in 1979) — only one reactor was involved in each. However, at the Fukushima No. 1 plant, four reactors went critical at the same time." On March 13, two days after the tsunami that followed the magnitude-9 Great East Japan Earthquake, Masataka Shimizu, the president of Tokyo Electric Power Co. (Tepco), the operator of the stricken nuclear plant, said at a press conference: "The tsunami was beyond all previous imagination. In the sense that we took all measures that could be thought of for dealing with a tsunami, there was nothing wrong with our preparations." As Hirose and many other commentators have pointed out, Tepco executives and government planners knew perfectly well that tsunamis far exceeding 20 meters in height struck that very region in 1896 and again, 37 years later, in 1933. The 14-meter-high tsunami that inundated many of the Fukushima No. 1 plant's facilities was, in fact, well within the parameters of what could objectively be termed "expected" — and was simply not "beyond all previous imagination," as Shimizu claimed.

In fact, the willful absence of care by both industry and government comprises nothing less than a blatant act of savagery against the people of Japan. This book is full of enlightening technical explanations on every aspect of nuclear safety, from structural safeguards (and their clear inadequacy) to the nature of hydrogen explosions and meltdowns. Hirose warns us, with detailed descriptions of the lay of the land and the features of each reactor, about the nuclear power plants at Tomari in Hokkaido, Higashidori in Aomori Prefecture and Onagawa in Miyagi Prefecture; about other plants in Ibaraki, Ishikawa, Shimane, Ehime, Saga and Kagoshima prefectures; and perhaps most dangerous of all, about the 14 reactors along the Wakasa Coast in Fukui Prefecture, constituting what I would call Hōshanō Yokochō (Radioactivity Alley). Many of the reactors at these plants are aging and plagued with serious structural problems.

Dismissed as a “nobody” by Japan’s nuclear industry, seismologist Katsuhiko Ishibashi spent two decades watching his predictions of disaster come true: First in the 1995 Kobe earthquake and then at Fukushima. He says the government still doesn’t get it.The 67-year-old scientist recalled in an interview how his boss marched him to the Construction Ministry to apologize for writing a 1994 book suggesting Japan’s building codes put its cities at risk. Five months later, thousands were killed when a quake devastated Kobe city. The book, “A Seismologist Warns,” became a bestseller.That didn’t stop Haruki Madarame, now head of Japan’s Nuclear Safety Commission, from dismissing Ishibashi as an amateur when he warned of a “nuclear earthquake disaster,” a phrase the Kobe University professor coined in 1997. Ishibashi says Japan still underestimates the risk of operating reactors in a country that has about 10 percent of the world’s quakes.

“What was missing -- and is still missing -- is a recognition of the danger,” Ishibashi said, seated in a dining room stacked with books in his house in a Kobe suburb. “I understand we’re not going to shut all of the nuclear plants, but we should rank them by risk and phase out the worst.”Among Japan’s most vulnerable reactors are some of its oldest, built without the insights of modern earthquake science, Ishibashi said. It was only in the last four years that Japan Atomic Power Co. recognized an active fault line running under its reactor in Tsuruga, which opened in 1970 about 120 kilometers (75 miles) northeast of Osaka and close to a lake that supplies water to millions of people in the region.New Fault LinesJapan Atomic is reinforcing the plant to improve quake tolerance and believes it’s safe despite the discovery of new active faults lines in 2008, Masao Urakami, a Tokyo-based spokesman for the utility, said.“We can’t respond to every claim by every scientist,” he said. “Standards for seismic ground motion are not decided arbitrarily, but are based on findings by experts assigned by the government.”

Reactor 1 at the Tsuruga plant, which had its license extended for 10 years in 2009, is one of 13 on Wakasa bay, a stretch of Sea of Japan coast that is home to the world’s heaviest concentration of nuclear reactors. The area is riddled with fault lines found in the last three or four years, according to Ishibashi.

During the 1970s and 1980s, at the peak of the nuclear reactor construction, organized groups of protestors mounted dozens of anti-nuke campaigns. They were called Chicken Littles, the establishment media generally ignored their concerns, and the nuclear industry trotted out numerous scientists and engineers from their payrolls to declare nuclear energy to be safe, clean, and inexpensive energy that could reduce America’s dependence upon foreign oil. Workers at nuclear plants are highly trained, probably far more than workers in any other industry; operating systems are closely regulated and monitored. However, problems caused by human negligence, manufacturing defects, and natural disasters have plagued the nuclear power industry for its six decades. It isn’t alerts like what happened at San Onofre that are the problem; it’s the level 3 (site area emergencies) and level 4 (general site emergencies) disasters. There have been 99 major disasters, 56 of them in the U.S., since 1952, according to a study conducted by Benjamin K. Sovacool Director of the Energy Justice Program at Institute for Energy and Environment  One-third of all Americans live within 50 miles of a nuclear plant.

At Windscale in northwest England, fire destroyed the core, releasing significant amounts of Iodine-131. At Rocky Flats near Denver, radioactive plutonium and tritium leaked into the environment several times over a two decade period. At Church Rock, New Mexico, more than 90 million gallons of radioactive waste poured into the Rio Puerco, directly affecting the Navajo nation. In the grounds of central and northeastern Pennsylvania, in addition to the release of radioactive Cesium-137 and Iodine-121, an excessive level of Strontium-90 was released during the Three Mile Island (TMI) meltdown in 1979, the same year as the Church Rock disaster. To keep waste tanks from overflowing with radioactive waste, the plant’s operator dumped several thousand gallons of radioactive waste into the Susquehanna River. An independent study by Dr. Steven Wing of the University of North Carolina revealed the incidence of lung cancer and leukemia downwind of the TMI meltdown within six years of the meltdown was two to ten times that of the rest of the region.

Although nuclear plant security is designed to protect against significant and extended forms of terrorism, the NRC believes as many as one-fourth of the 104 U.S. nuclear plants may need upgrades to withstand earthquakes and other natural disasters, according to an Associated Press investigation. About 20 percent of the world’s 442 nuclear plants are built in earthquake zones, according to data compiled by the International Atomic Energy Agency. The NRC has determined that the leading U.S. plants in the Eastern Coast in danger of being compromised by an earthquake are in the extended metropolitan areas of Boston, New York City, Philadelphia, Pittsburgh, and Chattanooga. Tenn. The highest risk, however, may be California’s San Onofre and Diablo Canyon plants, both built near major fault lines. Diablo Canyon, near San Luis Obispo, was even built by workers who misinterpreted the blueprints.  

The probability of an accident due to a nuclear plant is one is to infinity and all atomic power plants in the country conform to safety standards, chairman of Atomic Energy Commission Srikumar Banerjee said on Thursday. “At least 1.75 lakh people die due to road accidents in a single year whereas there are nearly 14,000 nuclear plants in the world and the casualty rate till date is just 52,” Dr. Banerjee told reporters on the sidelines of the golden jubilee celebrations of Terminal Ballistic Research Laboratory (TBRL) at Ramgarh, near Chandigarh. Pointing out that no human activity can be risk-free, he said there was a definite need for creating awareness and programmes should to be intensified to convince the people in the neighbourhood of a proposed or existing nuclear plant. He said human body faces more radiation during a CT scan than working in a nuclear power plant.

Referring to the recent Fukushima nuclear accident, Dr. Banerjee said it happened after a gap of 25 years and the cause and effect of the accident was earthquake followed by a tsunami. “It was not a nuclear accident... immediately after the earthquake, the nuclear reactor shut down and nuclear chain reaction stopped,” he said adding it was a complete station blackout as the decay heat produced in the plant could not be taken out. He, however, said the total casualty due to the nuclear accident was zero. “The spread of radiation was not as high as it was projected,” he said talking about the nuclear accident in Japan. After a nuclear reactor is shut down the energy level comes down to around 2 per cent from 100 per cent due to heat decay, Dr. Banerjee said. He, however, exuded confidence all nuclear plants in the country are safe and conform to the standards of Atomic Energy Regulatory Board and are taken care of by Nuclear Power Corporation. “India too experienced earthquakes and tsunami in the past but there was no nuclear accident as the nuclear plants had all the gadgets to give signal much in advance,” he said. Dr. Banerjee rejected that alarm bells had rung in India after the Japanese nuclear accident. “All steps needed for safety and security for nuclear plants have been taken by Nuclear Power Corporation,” he added.

He, however, stressed that it was necessary to strengthen the mechanism in the passive cooling system in nuclear plants in India. In the passive cooling system, heat can be taken out from the plant. Responding to a query regarding protests by habitants before setting up a nuclear plant in their neighbourhood, he said what is needed is to explain things to local people in simple local language and also convince them what actually the plant is. After land acquisition, a package must be given to the affected people and at all costs excellent relationship is needed with people living around the plant. He termed it as “baseless,” the allegation that nuclear radiation comes out from the nuclear plant. Besides, the plants along the coastal areas do not have any effect on the lives of fish, he added.

The U.S. military is preparing to lift a ban on some Japanese foods, imposed after the March 11 earthquake and tsunami triggered a nuclear scare.The Japan District Veterinary Command, which is responsible for food safety on U.S. bases, said Thursday that, within a month, products from 26 Japanese processing plants will once again be sold on U.S. installations.

Food deliveries from those factories were suspended due to a range of health concerns, including the proximity of some of them to the Fukushima Dai-ichi nuclear power station, which was severely damaged by the quake and tsunami, said Lt. Col. Margery Hanfelt, commander of the veterinary command.The suspended plants — among 60 that deliver to U.S. bases — produce a variety of foods ranging from baked goods and eggs to fresh fruit, vegetables and processed items. Some of the facilities, which Hanfelt declined to identify, were damaged by the earthquake while others had supplies of basic ingredients cut. For example, a farm supplying grain to one plant was destroyed by the tsunami, she said.

“As they recover, we are going through and re-auditing and re-assessing them,” she said.In the past month, teams of U.S. servicemembers have been inspecting the suspended plants — located in 13 prefectures in northern Honshu — and testing food samples for chemical, microbiological and radiological contamination, she said.

TEPCO has just released "diaries" from early in the accident giving us a better view of the sequence of events from the operators point of view.

The bulk of the materials, distributed on discs with digital files, show reams of raw numerical data. They include photos of broadsheet computer printouts and other formatted charts with thousands of data points for measurements of reactor heat, pressure, water levels, fuel rod positions and the status of cooling pumps, among other functions. Tokyo Electric, or Tepco, also released a smaller batch of more recent documents highlighting its various efforts to restore electric power to each of the reactors, a task that was achieved on April 26. But a series of what Tepco terms reactor "diaries" from the first 48 hours after the quake include the most visually arresting materials. These feature snapshots of whiteboards on which plant employees—11 of whom remained in each of the plant's three control rooms—jotted down status updates on the progress of the reactor shutdowns and steadily increasing radiation levels around the facility.

Using red, black or blue ink markers, the plant operators appear to have scribbled down the notes quickly. Many are smudged or illegible. Others depict complex diagrams and are peppered with technical jargon or acronyms such as SBO for "station blackout." http://online.wsj.com/article/SB10001424052748704281504576329011846064194.html

On Tuesday, the Energy Department, handing out research grants in all kinds of energy fields that are low in carbon dioxide emissions, is announcing that it will give $39 million to university programs around the country to try to solve various nuclear problems.

The money will go to a variety of projects at 31 universities in 20 states. Several focus on nuclear waste.

Two researchers at Clemson University, for example, will get $1 million to study the behavior of particles of nuclear waste when buried in clay in metal canisters that have rusted. One open question, according to the researchers, is how a high temperature, which would be generated by the waste itself, affects the interactions. These are important to understanding how the waste would spread over time. The goal is to “reduce uncertainty” about the life expectancy of atomic particles.

Scientists and doctors are calling for a new national policy in Japan that mandates the testing of food, soil, water, and the air for radioactivity still being emitted from Fukushima's heavily damaged Daiichi nuclear power plant."How much radioactive materials have been released from the plant?" asked Dr Tatsuhiko Kodama, a professor at the Research Centre for Advanced Science and Technology and Director of the University of Tokyo's Radioisotope Centre, in a July 27 speech to the Committee of Health, Labour and Welfare at Japan's House of Representatives. "The government and TEPCO have not reported the total amount of the released radioactivity yet," said Kodama, who believes things are far worse than even the recent detection of extremely high radiation levels at the plant. There is widespread concern in Japan about a general lack of government monitoring for radiation, which has caused people to begin their own independent monitoring, which are also finding disturbingly high levels of radiation. Kodama's centre, using 27 facilities to measure radiation across the country, has been closely monitoring the situation at Fukushima - and their findings are alarming.According to Dr Kodama, the total amount of radiation released over a period of more than five months from the ongoing Fukushima nuclear disaster is the equivalent to more than 29 "Hiroshima-type atomic bombs" and the amount of uranium released "is equivalent to 20" Hiroshima bombs.

Kodama, along with other scientists, is concerned about the ongoing crisis resulting from the Fukushima situation, as well as what he believes to be inadequate government reaction, and believes the government needs to begin a large-scale response in order to begin decontaminating affected areas.Distrust of the Japanese government's response to the nuclear disaster is now common among people living in the effected prefectures, and people are concerned about their health.Recent readings taken at the plant are alarming.When on August 2nd readings of 10,000 millisieverts (10 sieverts) of radioactivity per hour were detected at the plant, Japan's science ministry said that level of dose is fatal to humans, and is enough radiation to kill a person within one to two weeks after the exposure. 10,000 millisieverts (mSv) is the equivalent of approximately 100,000 chest x-rays.

t is an amount 250 per cent higher than levels recorded at the plant in March after it was heavily damaged by the earthquake and ensuing tsunami. The operator of Japan's crippled Fukushima Daiichi nuclear power plant, Tokyo Electric Power Company (TEPCO), that took the reading, used equipment to measure radiation from a distance, and was unable to ascertain the exact level because the device's maximum reading is only 10,000 mSv. TEPCO also detected 1,000 millisieverts (mSv) per hour in debris outside the plant, as well as finding 4,000 mSv per hour inside one of the reactor buildings.

A power loss shut down an off-site emergency response centre near the Fukushima No 1 nuclear power plant for half a day after the Great East Japan Earthquake on March 11, delaying the initial response to the nuclear disaster at the power plant, according to sources. According to the Nuclear and Industrial Safety Agency, the centre lost its external power supply immediately after the earthquake, and an emergency diesel generator stopped operating soon after. Due to the power loss, agency officials stationed at the centre were unable to use important equipment such as monitors that show conditions inside the plant. The agency, which believes the earthquake caused the generator to break down, had not taken any anti-seismic reinforcement measures to protect the generator, the agency said.

The government panel tasked with investigating the nuclear crisis has begun studying the case, according to the sources. The off-site centre is located in Okumamachi, Fukushima Prefecture, about five kilometres from the nuclear power plant.

After the nuclear catastrophe that followed the earthquake and tsunami in Japan last spring, some Central Virginia activists cautioned that a similar nightmare could unfold right here at the Dominion-operated North Anna nuclear generating plant in Louisa County. Despite Dominion's assurances that the plant made it through the August 23 earthquake unscathed, activists contend that the quake, which measured 5.8 on the Richter Scale and had an epicenter just eleven miles from the plant, may have been more catastrophic than anyone is admitting. New information bolsters their fears.

On Monday, August 29, the federal Nuclear Regulatory Commission announced that the quake may, in fact, have produced force that exceeded the North Anna plant's specifications and that the Commission is sending a special Augmented Inspection Team to assess the damage.

Initial reviews determined the plant may have exceeded the ground motion for which it was designed," says the release, which also assures that "no significant damage to safety systems has been identified."

Six months after a tsunami turned Japan’s northeast into a tangled mess of metal, concrete, wood and dirt, legions of workers have made steady progress hauling away a good portion of the more than 20 million tonnes of debris covering ravaged coastal areas. The Environment Ministry says it expects to have it all removed by next March, and completely disposed of by 2014. 'I think Tokyo Electric Power Company (TEPCO), as well as the Japanese government, made many mistakes.' —Shoji Sawada, theoretical particle physicist But a weightless byproduct of this country’s March 11 disaster is expected to linger for much longer.  The Japanese learned a lot about the risks posed by radiation after the United States dropped atomic bombs on Hiroshima and Nagasaki in 1945. Now, once again, they are facing this invisible killer. This time, the mistake is of their own making. "I’m afraid," says Shoji Sawada, a theoretical particle physicist who is opposed to the use of nuclear energy .  Sawada has been carefully monitoring the fallout from the accident at the Fukushima Daiichi power plant. “I think many people were exposed to radiation. I am afraid [they] will experience delayed effects, such as cancer and leukemia.” Evacuation zone Japan's government maintains a 20-kilometre evacuation zone around the Fukushima Daiichi plant, with no unauthorized entry allowed. The government has urged people within a 30-km radius of the plant to leave, but it's not mandatory. Some people say the evacuation zone should include Fukushima City, which is 63 km away from the plant. At the moment, the roughly 100,000 local children are kept indoors, schools have banned soccer and outdoor sports, pools were closed this summer, and building windows are generally kept closed. A handful of people argue the government should evacuate all of Fukushima prefecture, which has a population of about 2 million.  Sawada dedicated his career to studying the impact radiation has on human health, particularly among the survivors of Japan’s atomic bombings. His interest is both professional and personal. When he was 13 years old, his mother urged him to flee their burning home in Hiroshima. She died, trapped beneath rubble . “I think Tokyo Electric Power Company [TEPCO], as well as the Japanese government, made many mistakes,” he says. Those mistakes have been clearly documented since the earthquake and tsunami triggered meltdowns and explosions at TEPCO’s Fukushima Daiichi, some 220 kilometres northeast of Tokyo. Warnings to build a higher tsunami wall were ignored; concerns about the safety of aging reactors covered up; and a toothless nuclear watchdog exposed as being more concerned with promoting atomic energy than protecting the public

Asia Pacific Journal reports:

Japan’s leading business journal Toyo Keizai has published an article by Hokkaido Cancer Center director Nishio Masamichi, a radiation treatment specialist.

Nishio originally called for “calm” in the days after the accident. Now, he argues, that as the gravity of the situation at the plant has become more clear, the specter of long-term radiation exposure must be reckoned with.
