KORIYAMA, Oct. 31 — “Japan still is struggling to figure out how to clean up the mess, exacerbating fears about health risks and fanning mistrust of the government,” reports Yumiko Ono in today’s Wall Street Journal. In fact, government policies may be increasing the spread of radioactive particles: According to the article, “Some experts say some ad hoc cleanup efforts risk spreading radiation further.” For example, Ono says schools “are temporarily storing contaminated soil in holes dug within the school compounds and lined with plastic sheets.”

Of this ‘storage’ method, Kimberlee Kearfott, a University of Michigan nuclear-engineering professor who has served on U.S. government panels for nuclear cleanups, says: Plastic isn’t a long-lasting seal against radioactive substances leaking. If radioactive materials get into the ground water and are concentrated there that could be worse than soil contamination because it could spread rapidly. “This type of shallow-pit burial has not been used in the U.S. since the 1960s.” “This is definitely not a good idea.” Officials at Japan’s environment ministry “concede the task is daunting,” according to the Journal article.

During an interview, Vice Minister Hideki Minamikawa said: “We don’t have experience in this field.” “We’re talking about such a vast area.” “Currently, there are no clear signs yet on what needs to be done to make decontamination a success.”

astel Yamada is 73 years old. He seems a little tired after weeks on the road in the United States. He is trying to save Japan. One of the first people I have met who can tell the inside story of the Fukushima accident, Yamada is concerned that work is not being done on the three nuclear reactors that melted down last year because the high radiation levels are still keeping TEPCO workers away. The crippled buildings are unstable, still contain nuclear assemblies, and present a long term threat to the people in the area. The cooling systems especially are a cause for concern. Mr. Yamada, founder and president of the Skilled Veterans Corps for Fukushima (Fukushima Genpatsu Kodotai), along with 700 members, want to help clean up the site.

Beyond cleanup of the site, Mr. Yamada doesn’t believe TEPCO has the technological capabilities to deal with the long term issues. TEPCO, he says, doesn’t believe this either. TEPCO’s plan, according to Yamada, is to contain the radiation in the next 40 years. He estimates they will need 50 years or perhaps much longer

The U.S. nuclear safety chief said Tuesday that he is comfortable with Japan's announcement that its tsunami-damaged nuclear power plant has reached stable conditions, brushing off skepticism raised by experts. Gregory Jaczko, chairman of the U.S. Nuclear Regulatory Commission, said significant progress has been made at the Fukushima Dai-ichi nuclear power plant since the March disaster and that he welcomes Japan's decision to now move toward a cleanup and the plant's eventual closure. Measures taken by Japan have been consistent with how the U.S. would handle a similar crisis, he said. "I feel very comfortable that they have really completed the requirements that are necessary to move on to the next stage," Jaczko told reporters a day after inspecting the Fukushima plant. "These are really significant milestones that have been achieved and I think they made the right determination to move on to the next stage in the decontamination and decommissioning activities."

Hanford officials have settled on a plan to clean up what may be the most highly radioactive spill at the nuclear reservation. It depends on calling back into service the 47-year-old, oversized hot cell where the spill occurred to protect workers from the radioactive cesium and strontium that leaked through the hot cell to the soil below. Radioactivity in the contaminated soil, which is about 1,000 feet from the Columbia River, has been measured at 8,900 rad per hour [89 sieverts per hour]. Direct exposure for a few minutes would be fatal, according to Washington Closure. [...]

In the 1980s, cesium and strontium spilled inside the hot cell, according to a 1993 report that referenced the spill. Germany needed a heat source to use for tests of a repository for radioactive waste, which emits heat, and the cesium and strontium were being fabricated into the sources. “This was concentrated material,” said Mark French, the Department of Energy’s project director for Hanford cleanup along the Columbia River. [...]

It migrated down in a open square shape, with the worst contamination down to five or six feet deep, McBride said. There is not evidence that it has reached the ground water which is about 54 feet below the ground there and about 42 feet below the bottom of the hot cell [...]

During court proceedings concerning a radioactive golf course, Tokyo Electric Power Co. stunned lawyers by saying the utility was not responsible for decontamination because it no longer "owned" the radioactive substances. “Radioactive materials (such as cesium) that scattered and fell from the Fukushima No. 1 nuclear plant belong to individual landowners there, not TEPCO,” the utility said. That argument did not sit well with the companies that own and operate the Sunfield Nihonmatsu Golf Club, just 45 kilometers west of the stricken TEPCO plant in Fukushima Prefecture.

The Tokyo District Court also rejected that idea. But in a ruling described as inconsistent by lawyers, the court essentially freed TEPCO from responsibility for decontamination work, saying the cleanup efforts should be done by the central and local governments. Although the legal battle has moved to a higher court, observers said that if the district court’s decision stands and becomes a precedent, local governments' coffers could be drained.

The two golf companies in August filed for a provisional disposition with the Tokyo District Court, demanding TEPCO decontaminate the golf course and pay about 87 million yen ($1.13 million) for the upkeep costs over six months.

given the fact that a new study reports that the Columbia River will be contaminated with nuclear waste from a nuclear weapons plant for thousands—yes, thousands—of years. Even though the government has already spent billions of dollars on cleanup.

The Oregonian reports that the Hanford Nuclear Reservation, formerly a nuclear weapons production site, sits on 586 square miles of land next to the Columbia. And it has already leaked and spilled some waste into the river, contaminating the water and surrounding environment with such fun things as strontium, cesium, tritium, and plutonium. The federal government did an analysis of the damage to determine if capping and sealing off the waste would stop more of it from getting out, and also, if more waste could be imported to the site to be buried along with the original waste.

The analysis also shows that the U.S. energy department's plan to import low-level and midlevel radioactive waste from other sites to Hanford after 2022 poses "completely unacceptable" risks, [assistant director of the Oregon Department of Energy Ken] Niles said. Washington is also raising concerns about importing more waste. […] Health risks from Hanford's contamination are long-term, not immediate. They're expressed in terms of cancer cases after a lifetime of drinking well water from the site, with a one in 10,000 risk considered high. But many of the contaminant levels at the site exceed health benchmarks by wide margins.

In the first few days of Japan’s nuclear crisis this spring, the U.S. military wasn’t fully prepared to deal with possible radiation exposure to its troops and equipment, the top U.S. general in Japan said Wednesday.

U.S. Forces Japan commander Lt. Gen. Burton M. Field talked about the radiation risk to U.S. troops during a briefing on Operation Tomodachi for members of the American Chamber of Commerce in Japan on Wednesday.

“As the (Fukushima Dai-ichi) reactors exploded and they sent some of that radiation out, we had the issue with it being detected off shore by the Navy,” he said. “We had to start dealing with the kind of environment that the U.S. military had not really worked in, so we didn’t have the strictest guidelines on what kind of risk we would take in terms of radiation exposure for our (service) members.”

Milepost 231 now marks the end of the road. Barricades prevent traffic from proceeding farther north on Highway 6, a four-lane road that leads to the ruin of the Fukushima Daiichi nuclear power plant. Men in uniform are waving stop signs. In the evening twilight, a red illuminated sign flashes the following message: "No access… disaster law." Two policemen armed with red glow sticks vigorously turn away every lost driver. Three of their colleagues are blocking the exit to the right. They yell at anyone approaching on foot.

A total of 20 officers guard this intersection, day and night. To the right of the road block, the highway leads to J-Village, a former training center for the Japanese national soccer team. Since March 11, Japan's largest soccer complex has been transformed into the base camp for Japan's peculiar heroes -- the workers who are trying to regain control of the crippled Fukushima Daiichi nuclear power plant. More than 1,000 of these workers prepare themselves for their shifts here, day after day. The TEPCO power company, which is the operator of the stricken nuclear power plant, sponsored construction of the sports facility years ago. Since it has become the hub for the nuclear cleanup workers, though, the company has sealed off the area to the media and the general public.

Temporary Workers Doing the Dirty Work One of the workers feels that the public has a right to know what is happening in J-Village. He has decided to speak with SPIEGEL, although he would prefer not to give his name. He will be referred to as Sakuro Akimoto here. On busy days, he says, more than 3,000 workers pass through the radiation detection station.

Remember the time when the TEPCO/government complex pretended that it would fill the Containment Vessels of Reactors 1, 2 and 3 with water to cool the Reactor Pressure Vessels inside? It was late April, TEPCO started to pour an enormous amount of water in the RPV of Reactor 1 to fill the Vessel (as the water would leak into the CV). The operation was dubbed "water entombment".

We know how it quickly ended. TEPCO finally managed to actually measure the water level inside the CV and RPV of Reactor 1, and found that there was hardly any water in either of them - i.e. both the CV and the RPV of Reactor 1 were broken, kaput. Of 10,000 tonnes of water that TEPCO poured into the CV of Reactor 1, 3,000 tonnes were discovered in the basement.

But now, the water entombment is back in discussion in conjunction with decommissioning the reactors at Fukushima I Nuclear Power Plant, according to Mainichi Shinbun (8/31/2011).

It is unconfirmed information, which may not be confirmed at all even if it is true as it may have been the "administrative guidance" from the government without a formal document. Plausible deniability has been one of Japan's forte over hundreds of years if not thousand. A resident of Fukushima City, responding to one of the tweets about why the farmers in Fukushima farmed at all this year and continue to sell produce even when they are aware that the land is heavily contaminated with radioactive fallout from Fukushima I Nuclear Power Plant, says the following:

Everyone was saying "We can't farm this year". Then the national government said to them, "Farm as usual".She also says in an earlier tweet:

I live in Fukushima City. None of the people around me eat [Fukushima produce]. Even the farmers say "We can't eat this year['s produce]". I personally believe it's "we can't eat from now on".Vegetables, meat, rice that even some people in Fukushima don't eat are being promoted and sold all over Japan.

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

The scars of Japan’s March 11 disaster are both glaringly evident and deceptively hidden. 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.

In another propaganda show meant to convince the public there is no threat from radiation in Japan, local schools forced children to clean radioactive dirt from the bottom of the schools swimming pools. One PTA member who didn’t trust the assertions from the school and the government kept a sample of the dirt collected from the pool and decided to have it tested for radiation

According to a the Mainichi Daily News (Japanese), that sample was found to contain 17,020 becquerels per kilogram of radioactive cesium. Here is an English translation of the Mainichi Shinbun article as posted on Yahoo News, 7/5/2011, provided, by EX-SKF

East earthquake: Community School of cesium from the mud pool Joso, Ibaraki / 2 times the allowable standard landfill It was disclosed that 17,020 becquerels per kilogram of radioactive cesium was detected from the dirt that were scooped out from the swimming pool when the teachers and pupils of one public elementary schools in Joso City did the cleaning of the pool in May. The amount is more than twice the safety limit set by the Ministry of the Environment for the radioactive debris that could be buried. The school moved the dirt in a separate area. Upon this news, the city’s Board of Education surveyed the situation of the pool dirt in city’s elementary schools and junior high schools on July 4, and found out there were 4 other elementary schools who had kept the dirt on the school premises.

The basic plan for decontamination and treatment of radioactive materials released from the crisis-stricken Fukushima No. 1 nuclear plant has been decided on. Under its provisions, the central government will designate areas with radioactive emissions of 1 millisievert per year or more “important contamination condition survey sites,” and will task local governments with cleanup operations. At first, the Environment Ministry told the Fukushima Prefectural Government and local municipalities that it planned to designate primarily areas with annual emissions of 5 millisieverts for contamination surveys. However, following strong opposition to this figure from local governments, Environment Minister Goshi Hosono — who is also minister of state for the nuclear accident — declared that the plan would be revised. One millisievert per year is the upper exposure limit set by the International Commission on Radiological Protection (ICRP) for regular citizens

the Defense Nuclear Facilities Safety Board (DNFSB), an independent organization tasked by the executive branch to oversee public health and safety issues at the DOE's nuclear facilities. In a report addressed to Secretary of Energy Steven Chu, DNFSB investigators wrote that "both DOE and contractor project management behaviors reinforce a subculture . . . that deters the timely reporting, acknowledgement, and ultimate resolution of technical safety concerns."

After reviewing 30,000 documents and interviewing 45 staffers, the DNFSB reported that those who went against the grain and raised concerns about safety issues associated with construction design "were discouraged, if not opposed or rejected without review." In fact, according to the DNFSB, one of these scientists, Dr. Walter Tamosaitis, was actually removed from his position as a result of speaking up about design problems.

It's not just the DNFSB that is concerned with the safety culture and management at Hanford. Seattle Weekly has obtained official documents revealing that the Government Accountability Office (GAO), the Congressional arm in charge of investigating matters relating to contractors and other public fund recipients, visited the Hanford site last month. In an outline sent to DOE personnel in advance of their visit, the GAO wrote that it will look into how contractors are addressing concerns over what they call "relatively lax attitudes toward safety procedures," "inadequacies in identifying and addressing safety problems," and a "weak safety culture, including employees' reluctance to report problems." Their findings likely will be made public in early 2012.

TOKYO — Nuclear workers at the crippled Fukushima power plant raced to inject boric acid into the plant’s No. 2 reactor early Wednesday after telltale radioactive elements were detected there, and the plant’s owner admitted for the first time that fuel deep inside three stricken plants was probably continuing to experience bursts of fission.

The unexpected bursts — something akin to flare-ups after a major fire — are extremely unlikely to presage a large-scale nuclear reaction with the resulting large-scale production of heat and radiation. But they threaten to increase the amount of dangerous radioactive elements leaking from the complex and complicate cleanup efforts, raising startling questions about how much remains uncertain at the plant, the site of the world’s worst nuclear disaster since Chernobyl. The Japanese government has said that it aims to bring the reactors to a stable state known as a “cold shutdown” by the end of the year.

On Wednesday, the plant’s operator, the Tokyo Electric Power Company, said that measurements of gas from inside Reactor No. 2 indicated the presence of radioactive xenon and other substances that could be the byproduct of nuclear fission. The presence of xenon 135 in particular, which has a half-life of just nine hours, seemed to indicate that fission took place very recently.
