Workers spread lining sheets in a huge trench dug to bury radiation-contaminated topsoil collected from the ground of Yasawa Elementary School and Kindergarten in Minami-Soma, about 20 kilometers away from the tsunami-crippled Fukushima Dai-ichi nuclear facility, in Fukushima Prefecture, northeastern Japan, Thursday, Aug. 18,

"Most of the radioactive cesium emitted by the crippled Fukushima No. 1 Nuclear Power Plant has piled up within two centimeters of the soil surface, the government has announced."

snip

"The survey, conducted between July and September, covered the Fukushima Prefecture town of Tomioka, which is designated as a no-go zone, and the town of Namie, which has both a no-go zone and an evacuation preparation zone. Officials said 80 to 97 percent of cesium detected in those areas' schools, parks, rice paddies and other locations was found within two centimeters of the soil surface."

snip

"Meanwhile, fruits of trees that have grown in places with high cesium concentrations in the soil hardly bore cesium, the survey has found."

Some land in Japan too radioactive to farm: study

"Farmland in parts of Japan is no longer safe because of high levels of radiation in the soil, scientists have warned, as the country struggles to recover from the Fukushima atomic disaster."

snip

"Fukushima prefecture as a whole is highly contaminated," especially to the northwest of the nuclear power plant, the researchers said.

The study looked at caesium-137, which has a half life of 30 years and therefore affects the environment for decades."

snip

The legal limit for concentrations in soil where rice is grown of the sum of caesium-134 and caesium-137, which are always produced together, is 5,000 becquerels per kilogram (2.2 pounds) in Japan.

"The east Fukushima prefecture exceeded this limit and some neighbouring prefectures such as Miyagi, Tochigi and Ibaraki are partially close to the limit under our upper-bound estimate," the study said.

"Estimated and observed contaminations in the western parts of Japan were not as serious, even though some prefectures were likely affected to some extent," it added.

snip

An official in charge of soil examination for the agriculture ministry said government tests had been conducted on soil in Fukushima and five other prefectures earlier this year.

He said contamination levels in Fukushima had exceeded 5,000 becquerels per kilogram, but were below that level elsewhere.

"We are now conducting further checks covering 3,000 spots in Tokyo and 14 prefectures and plan to publish the results later," he said.

Half of radioactive materials from Fukushima fell into sea: study

20110822p2g00m0dm008000p_size5.jpg

In this June 30, 2011 photo released on July 5, 2011, by Tokyo Electric Power Co., sliding concrete slabs, seen above orange floats, have been set in the upper part of a sluice screen for the Unit 2 reactor at the tsunami-crippled Fukushima No. 1 Nuclear Power Plant in Okuma, Fukushima Prefecture, as part of TEPCO's efforts to reduce the leaking of radiation contaminated water into the ocean.

"TOKYO (Kyodo) -- More than half of the radioactive materials that were emitted into the atmosphere in the days after the Fukushima nuclear disaster have since fallen into the ocean, according to a recent simulation by a team of researchers.

Between 70 and 80 percent of the radioactive cesium from the Fukushima Daiichi power plant in Fukushima Prefecture had fallen into the sea by April, with the rest having fallen on land, according to the simulation done by the Meteorological Research Institute in Tsukuba, Ibaraki Prefecture, and other researchers."

snip

"On the premise that the materials were dispersed with each particle being the size of less than 1 micrometer, the simulation showed they largely completed a trip around the globe in roughly 10 days after first crossing the Pacific."

Once released into the atmosphere, the materials were dispersed mostly northbound and reached the western coast of the mainland United States around March 17 after passing through eastern Russia and Alaska, according to the simulation. They are likely to have largely completed a round-the Earth trip around March 24.

Most of the radioactive materials fell with rain as they got carried through the atmosphere, the study showed, saying that about 65 percent of the cesium-131 released into the air in the disaster has since fallen into the sea.

Japan mulling banning cesium-tainted rice shipments from Fukushima

snip

"We're considering restricting shipments of rice harvested in the Onami area in the city of Fukushima...and we'll draw a conclusion swiftly," Fujimura, the government's top spokesman, said at a press conference.

Excessive levels of radioactive cesium were found Wednesday in rice harvested in the area, the first time such levels of the isotope have been detected in the national staple since the crisis erupted at the Fukushima nuclear power station, crippled by the devastating March 11 earthquake and tsunami."

Unfortunately I did, as you know I do tend to track these nasty little particles.... lucky Iodine 131 only has a half life of 8 days..... if it was 12 days I would be getting concerned....

The Cesium levels have been creeping up world wide as well as some others, the worlds answer to this is to change the min and max acceptable  levels... oh our governments love their people so much....

The Prometheus Trap / Men in Protective Clothing-6: Policeman forbidden from telling the truth

The Prometheus Trap/ Men in Protective Clothing-5: 'I couldn't tell you then'

November 25, 2011Tweet

By MOTOYUKI MAEDA / Staff Writer

This is the sixth installment of an eight-part series looking at the fate and experiences of Mizue Kanno in Namie, Fukushima Prefecture, and 25 people who evacuated to her home, following the crisis at the Fukushima No. 1 nuclear power plant. Each installment is interconnected.

* * *

On March 14, Kazuyo Sekiba, 52, fled to her relative's home in Aizu-Wakamatsu, Fukushima Prefecture. She had lived in the Minami-Tsushima district of Namie, near Mizue Kanno's home.

Since no instructions for evacuation were given, she returned home on April 2, for the time being. After a few days, a Self-Defense Forces (SDF) jeep stopped in front of her house and an SDF serviceman got out. He said he had come to check on her safety.

Around that time, it had been reported that the radiation levels in Namie were high. Concerned about the reports, she asked nervously, "How high are the readings around here?"

The SDF man smiled and told her the area was fine.

"We're wearing a dosimeter, so we know how much radiation we're exposed to each day."

Sekiba felt relieved after hearing that. She stopped hiding in her house and went out into the neighborhood.

On April 17 when she stood on a bridge near her home, a man walked toward her. It was Naomi Toyoda, 55, a freelance journalist. Sekiba asked him to measure the radiation levels at her home, and he began taking measurements around her yard.

When he measured the area under the rain gutter in her entranceway, he stood up and exclaimed, "Wow. This is too bad."

Sensing his hesitance, Sekiba asked Toyoda to tell her the truth.

He told her, "In two hours, you would absorb 1 millisievert."

According to Toyoda, at that time the radiation level exceeded 500 microsieverts per hour. In just two hours a person would exceed the annual permissible exposure of 1 millisievert.

Upon hearing a specific number for the first time, Sekiba at last realized just how serious it was. She hurriedly prepared to leave and fled her home, seen off by Toyoda.

A few days later, when she returned home to get her cat, a patrol car of the Tokyo Metropolitan Police Department drove up.

She said to the policeman, apparently in his 30s, "This area had a high level of radiation, didn't it?"

"Yes, it was high. But I was forbidden to tell people by the government," he answered.

Sekiba was shocked. What about what the SDF man in the jeep had told her?

"If I had been his own family, could he have said the same thing? Wouldn't he immediately tell us to get away? Is it just someone else's problem?"

In July, it was revealed that evidence had been hidden in the high-speed train accident in China. The Japanese media sharply criticized the Chinese government's responses.

Sekiba said she is angry.

"The situation in Japan is almost the same as in China."

A joint study by Kyoto University and the University of Tsukuba, among other entities, estimated that water at the mouth of the Abukumagawa river running through the prefecture was contaminated with cesium levels over 50 billion becquerels a day.

The findings showed that the Abukumagawa river is releasing up to 52.4 billion becquerels of cesium per day into the sea, the report said.

Study Shows Worse Picture of Meltdown in Japan

Nov 30, 2011

TOKYO — "Molten nuclear fuel may have bored into the floor of at least one of the reactors at the stricken Fukushima Daiichi nuclear power plant, the complex’s operator said Wednesday, citing a new simulation of the accident that crippled the plant in March."

The simulation suggested that the meltdown may have been more severe than had previously been thought.

"Soon after an earthquake and a tsunami on March 11 knocked out cooling systems at the power plant, nuclear fuel rods in three of its six reactors overheated and slumped, the operator, the Tokyo Electric Power Company, has said.

In the No. 1 reactor, the overheated fuel may have eroded the primary containment vessel’s thick concrete floor, and it may have gotten almost within a foot of a crucial steel barrier, the utility said the new simulation suggested. Beneath that steel layer is a concrete basement, which is the last barrier before the fuel would have begun to penetrate the earth."

snip

"I have always argued that the containment is broken, and that there is the danger of a wider radiation leak,” Mr. Koide said. “In reality, it’s impossible to look inside the reactor, and most measurement instruments have been knocked out. So nobody really knows how bad it is.”

snip

"Because the simulation suggests that heat released as a result of radioactive decay “far overwhelmed” the effect of the cooling water, he said, and because temperatures in the inner pressure vessel that originally housed the fuel are thought to have dropped quickly, Tepco now assumes that “100 percent of the fuel at Unit 1 has slumped” into the outer primary containment vessel." 

"In addition, the simulation suggests that the fuel bored more than two feet into the concrete, Mr. Matsumoto said."

Inside Japan’s Fallout Zone: Children’s Growth Severely Stunted From Nuclear Disaster

Eight months after the crippled Fukushima-Daiichi nuclear plant belched enormous plumes of radiation over the Japanese countryside, a new study reveals severely stunted growth in children living in the fallout zone. Those findings coupled with another alarming piece of news from the Tokyo Times – “Radiation affects 8 percent of Japan’s territory” – indicate that tens of thousands of children could experience serious “physical problems” across a significant portion of the country. And that’s long before cancer even becomes an issue for these children.

Fukushima Daiichi Nuclear Power Plant:Highly Radioactive Water Leaks From Crippled Japanese Facility

r-WATER-LEAKS-FROM-CRIPPLED-JAPANESE-NUKE-PLANT-large570.jpgIn this Nov. 12, 2011 file photo, workers in protective suits and masks wait to enter the emergency operation center at the crippled Fukushima Dai-ichi nuclear power station in Okuma, Japan. (AP Photo/David Guttenfelder, Pool, File) 

"TOKYO -- Japan's crippled nuclear power plant leaked about 45 tons of highly radioactive water from a purification device over the weekend, its operator said, and some may have drained into the ocean.

"The leak is a reminder of the difficulties facing Tokyo Electric Power Co. as it tries to meet its goal of bringing the tsunami-damaged Fukushima Dai-ichi nuclear power plant to a cold shutdown by year's end."

A pool of radioactive water was discovered midday Sunday around a decontamination device, TEPCO said in a statement on its website. After the equipment was turned off, the leak appeared to stop. Later, workers found a crack in a concrete barrier leaking the contaminated water into a gutter that leads to the ocean.

TEPCO estimated about 300 liters leaked out before the crack was blocked with sandbags."

"Officials were checking whether any water had reached the nearby ocean."

"The pooled water around the purification device was measured Sunday at 16,000 bequerels per liter of cesium-134, and 29,000 bequerels per liter of cesium-137, TEPCO said. That's 270 times and 322 times higher, respectively, than government safety limits, according to the Citizens' Nuclear Information Center in Tokyo."

Wanted to put this up yesterday ...but have a think about how they have stopped the flow "WITH SAND BAGS" those bags will be more radiated than dirty bombs... feel for the poor buggers that are having to work with shovels and sand bags.....

It shows how primitive the authorities can be.... there is a worse component to this as well in that they are still to confirm on MSM the extent of the leakage into the ground below the reactor....

As I said spare a thought for the workers and there short lives...

“Everything is out of control”

Posted by Mochizuki on December 8th, 2011 ·

Actual Fukushima worker “Mr.Happy” confesses what is in his mind, more honestly than ever.

Today the gas (mainly hydrogen gas) control system at reactor 1 has finally got into the test drive mode. The makers are different from reactor 2, so it took us time to build it for reactor 1.

The next step is to build another gas controlling system for reactor 3, but we need to fix the crane first. Maybe we can’t get it down by the end of this year..

This week we’ve seen so many wild cows (Cows at farms were released after 311 and they live in the wild now.) on route 6, where is for the Fukushima plants. I guess cows are moving to somewhere warm toward winter .. The day before yesterday, a car from Fukushima Daini crashed into a cow and had the car burnt completely.

It’s hard to see black cows at night. I saw group of cows moving today and yesterday. feel like they are moving to south gradually. I wonder what the police does if they reach to the boarder of 20 km area.

Today they were supposed to announce a “big project”, but they didn’t. I asked someone “why”, he said there were some troubles to solve so it’s taking time. They are re-making the plan again.

They say it’s going to start at 12/21/2011.

Self defense force entered Fukushima plants area since yesterday. They came to decontaminate. They are planning to make bases at Naraha, Tomioka, and Namie. I saw numbers of their cars. Self defense force cars remind me of when 311 happened.

Government seems to plan to declare “Step2 is accomplished” on 12/16/2011 but actually nothing changes at the plants.

Government wants to declare the complete of step 2 during this year to pull back the residents to the planned evacuation zone and minimize the alerting area.

However, Naraha and Hirono, where the government lifted the evacuating area, haven’t had more then half of the population come back. Schools are still closed too. Government can’t pull people back to the zone even if they declare the safety.

It is expected to take more than 30 years to decommission crippled reactors at the Fukushima No. 1 Nuclear Power Plant, and workers tasked with the difficult mission would have to venture into "uncharted territory" filled with hundreds of metric tons of highly radioactive nuclear fuel, experts say.

After the expert committee of the Japan Atomic Energy Commission (JAEC) compiled a report on procedures to decommission the No. 1 to 4 reactors at the Fukushima No. 1 Nuclear Power Plant on Dec. 7, the actual work is expected to move into high gear after the turn of the year. As in the case of the 1979 Three Mile Island accident, the workers would try to remove melted nuclear fuel after shielding radiation with water, a technique called a "water tomb." But the work would have to be done in a "territory where humans have not stepped into before," said a senior official of Tokyo Electric Power Co. (TEPCO), the operator of the troubled Fukushima nuclear power station. The work is so difficult that it is expected to take more than 30 years to finish decommissioning the reactors.

The key part of the decommissioning work is to remove a total of 1,496 fuel rods from the No. 1 to 3 nuclear reactors and 3,108 fuel rods from nuclear fuel pools of the No. 1 to 4 reactors. The government and TEPCO are expected to start decommissioning the reactors early in the New Year after unveiling detailed plans around Dec. 16 that the nuclear plant has been brought under control by achieving a stable state called a ''cold shutdown.''

According to experts, filling the containment vessels with water completely to shield radiation is the "foremost and biggest hurdle." In order to carry out the task, it is necessary to spot and repair damaged parts in the containment vessels. But it is not an easy task. Up to about 5,000 millisieverts per hour of radiation -- lethal levels -- have been detected in the reactor building of the No. 1 reactor.

In the work schedule announced in April, TEPCO said it would bring the nuclear plant under control by filling the reactors with water. But subsequent analysis of the accident suggested that the No. 1 and 2 reactors had holes of up to 50 square centimeters caused by hydrogen explosions and the like. In the work schedule announced in May, TEPCO said it had scrapped its plan to repair the containment vessels and suspended the work to fill them with water.

Moreover, workers have been fighting an uphill battle to remove crumbled fuel. The reactors had been running without cooling water for a long time, and most of the fuel melted and apparently dropped into the containment vessel from the bottom of the pressure vessel at the No. 1 reactor.

A single fuel rod contains about 170 kilograms of uranium, and a simple calculation suggests that about 254 tons of uranium in the reactors alone must be recovered. The distance between the upper lid and the bottom of a containment vessel is up to 35 meters. From that far away, the work has to be done to chop off and recover melted and crumbled fuel by using remote controlled cranes. Furthermore, the melted fuel is mixed with metal from fuel pellets and reactor parts.

"The decommissioning work should be moved up and finished promptly," said Fukushima Gov. Yuhei Sato. He submitted a 6-item statement to the JAEC's expert committee. But at the meeting on Dec. 7, the expert committee did not give any in-depth response but simply added to its report that "We will urge people concerned to realize it as soon as possible." Kyoto University professor Hajimu Yamana, who heads the expert committee, said on Dec. 7, "Because no one has seen the inside of the nuclear reactors, the timing of starting the work to recover nuclear fuel mentioned in the report is only a nonbinding target."

Hi Phillip

Glad to see you are keeping people informed about what is happening. They are soon going to run out of space to

store all of that contaminated water. It's just an excuse to dump it back into the sea, saying it's low level contamination

What is their low level?? bet it's not good for you or the fish for that matter

Just quietly they have been releasing large amounts of contaminated water every week since the meld down... this is why the min Bac level limit has been raised from 5 bec's to 20+ bec's... West coast of US is up over 14 bec right now if not more....

The more you dig in the more you will realise the entire Northern Hemisphere is being polluted via the jet stream and other sea going currents.

THIS WEEK ON 'Y BYD AR BEDWAR'

What next for nuclear?

In the first of two special programmes examining the nuclear industry, this week we will be travelling to Fukushima.

Y Byd ar Bedwar is one of only a handful of television crews that has dared visit the boundary of the exclusion zone surrounding the area’s nuclear power plants, and our exclusive pictures will reveal the true levels of radiation in this area of Japan, 8 months following the disaster.

We will also be questioning two women from Anglesey who live in Japan, and asking whether a new nuclear power station should be built on the Wylfa site.

Y Byd ar Bedwar, Monday night 9.30pm on S4C.

Fukushima Prefecture's Latest "Decon" Technology: Leaf Collector

Fukushima Prefecture officials are ready to call "engine bloomer" - a leaf collector - as a powerful tool to decontaminate.

From Mainichi Shinbun Fukushima local version (12/11/2011):

The prefectural government of Fukushima tested the decontamination technology to effectively collect fallen leaves on the lawn on December 9 in Shirasakanomori Sports Park in Shirakawa City.

The government is testing the effectiveness of various decontamination technologies in several locations in Fukushima. On December 9, they tested the German-made leaf collector proposed by a landscaping company in Shirakawa City.

The leaf collecter is called "Engine Bloomer" which uses a rotating plastic brush to scrape leaves off the lawn. It has a big collecting power without damaging the trees, and it may be effective in decontaminating the lawn and orchards.

In the test, the president of the landscaping company removed the dead leaves on the lawn using the "Engine Bloomer". The radiation level 1 centimeter off the ground was 0.44 microsievert/hr before the test, which dropped to 0.24 microsievert/hr after the test. The Fukushima prefectural government will ask the decontamination advisor of the prefecture to evaluate this technology, and plans to make it public.

So, a leaf collector, by virtue of collecting the dead, radioactive leaves off the lawn, is called "decontamination technology". Just like a high-pressure washer is called exactly that because it washes the roof and the wall contaminated with radioactive materials.

Fukushima Prefecture's decon advisor is none other than Shunichi Tanaka, former Deputy Commissioner of the Nuclear Commission. The last I saw him on a Youtube video, he was telling the decon volunteers in Date City in November to use their own judgment whether to put on masks because the local residents didn't dress like these volunteers. Don't alarm the residents, he was basically saying, even though he was there to ensure the volunteers were protected from radiation exposure.

Now, you may ask why Fukushima Prefecture is doing all these bizarre "decon" experiments. Answer: to retain the residents. Why? Because if the residents move out of Fukushima permanently (i.e. removing the resident registers to other prefectures) the prefecture will lose grants from the national government, which are based on the number of residents in the prefecture. Less residents, less money for the Fukushima government. Less money for the government, less power for the politicians.

Confirmed: Fukushima disaster contaminated ocean with 50 million times normal radiation, leaks still ongoing

Learn more: http://www.naturalnews.com/034395_Fukushima_cesium_radiation.html#ixzz1gPlsp6fN

(NaturalNews) Things are suddenly heating up again with Fukushima. As we reported yesterday, the southern wall of Fukushima reactor #4 apparently collapsed over the past few days, calling into question the structural integrity of the remainder of the containment building (http://www.naturalnews.com/034387_F...).

The mainstream media has said absolutely nothing about this development, continuing its pattern of downplaying news involving Fukushima, radiation or the flawed structure of nuclear power plants. This is hardly surprising, given that many of the largest media outlets (such as NBC and MSNBC) are owned by corporations such as General Electric, the designer of many of the world's nuclear power plants. (http://www.freepress.net/ownership/...)

Photos of the failed structure have emerged on Enenews.com, where a report explains that a once-intact wall is now essentially "missing" and that further degradation of the structure could lead to mass evacuations in Japan (http://enenews.com/report-confirmed...). As this report is still not confirmed by other sources, we continue to take this with a sense of caution here at NaturalNews. We will continue to monitor the situation and report any relevant developments.

50 million times higher radiation levels

What has hit the mainstream media, however, is a report entitled Impacts of the Fukushima Nuclear Power Plants on Marine Radioactivity, authored by Ken Buesseler, Michio Aoyama, and Masao Fukasawa (http://pubs.acs.org/doi/abs/10.1021...).

This report, published in Environmental Science & Technology, reveals that levels of radioactive cesium reached 50 million times normal levels in the ocean water off the coast of the Fukushima Dai-ichi facility. Even more concerning, the abstract of this paper concludes, "...the concentrations through the end of July remain higher than expected implying continued releases from the reactors or other contaminated sources, such as groundwater or coastal sediments."

This, of course, contradicts mainstream media reports which for the most part stated that the radiation was "contained" and was not leaking directly into the environment. Only the alternative press has covered the real story on Fukushima, which has now become the worst radiological accident in the history of human civilization.

This same study ultimately concludes that this level of radiation contamination of the ocean is essentially harmless, stating, "...dose calculations suggest minimal impact on marine biota or humans due to direct exposure in surrounding ocean waters, though considerations for biological uptake and consumption of seafood are discussed and further study is warranted." That's a conclusion to be viewed with skepticism and caution, of course, as it says on one hand that "it's no problem" and yet on the other hand, maybe you shouldn't eat the seafood because we really don't know what quantity and concentration of radioactive elements may be ingested and concentrated by seafood sources.

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.

From Zakzak (12/13/2011):

"The explosion in Reactor 3 at Fukushima I Nuke Plant on March 14 was nuclear!"

So says Mr. Setsuo Fujiwara, who worked at Japan Nuclear Energy Safety Organization (JNES) until the spring of 2010 as nuclear plant inspector. He is one of those experts who know the nuclear power plant facilities and operations in great details.

"In the Reactor 3 explosion, there was a flicker of fire, then a vertical, black smoke up the reactor building. A hydrogen explosion does not produce such a black smoke. And the mushroom cloud. It resembles a nuclear explosion."

But according to the government and TEPCO, the nuclear reactors are getting more stable, aren't they?

"A more important source of radioactive materials dispersed is the Spent Fuel Pools."

If the spent fuel had melted and sank to the bottom of the pool, would that cause a nuclear explosion?

"The amount of cooling water decreased in the Reactor 3 SFP prior to the explosion, and hydrogen was generated from the zircaloy-water reaction. The upper part of the cladding melted, and the pellets fell out and piled [at the bottom of the pool?]. Inside the SFP, it was like a nuclear reactor becoming critical, and the water boiled. Then there was a hydrogen explosion above the surface of the water in the SFP, and due to the pressure from the explosion, voids (steam bubbles) in the boiling water were compressed. The void coefficient was negative, so the reactivity of nuclear fission was suddenly heightened, resulting in a nuclear explosion from the prompt criticality. When you see the slow-motion video of Reactor 3's explosion, you hear three explosive sounds. It is the evidence that the nuclear explosion occurred after the hydrogen explosion."

Next, he points to the pipe that connected the exhaust stack and Reactor 3. The big pipe is broken, and the short segment of the pipe is lying on the ground.

"TEPCO explained that the hydrogen gas generated in Reactor 3 passed through this pipe and entered the reactor building of Reactor 4, causing the hydrogen explosion in Reactor 4 which was in regular maintenance at that time. However, if you look at the photo, the pipe is broken. I think it was a hydrogen explosion in Reactor 4 also, caused by hydrogen generated inside the Spent Fuel Pool. If Reactors 3 and 4's hydrogen came from the Spent Fuel Pools, is it possible that the explosion of Reactor 1 was also caused by hydrogen from the Spent Fuel Pool? But no one is questioning [TEPCO] hard on these important points in reconstructing the accident."

Fujiwara says he tried to run his scenario of the accident with the engineers who are anti-nuclear, but that they withheld comments. "Japanese engineers are too reluctant to comment on things outside their specialties", says Fujiwara, irritated.

Real cause of nuclear crisis

Tokyo Electric Power Co. (Tepco), the operator of the stricken Fukushima No. 1 Nuclear Power Station, has been insisting that the culprit that caused the nuclear crisis was the huge tsunami that hit the plant after the March 11 earthquake. But evidence is mounting that the meltdown at the nuclear power plant was actually caused by the earthquake itself.

According to a science journalist well versed in the matter, Tepco is afraid that if the earthquake were to be determined as the direct cause of the accident, the government would have to review its quake-resistance standards completely, which in turn would delay by years the resumption of the operation of existing nuclear power stations that are suspended currently due to regular inspections.

When a Diet committee looking into the incident asked Tepco to submit a copy of the manual, most pages of the documents so submitted were "blacked out," as the company alleged they contained trade secrets which it did not want to go into the public domain.

Totally dissatisfied, the committee issued another order to Tepco to submit the whole manual in its original form, to which the company complied on Oct. 24. This led journalist Tanaka to come to the conclusion that the utility was not telling the truth.

Atsuo Watanabe, former designer of containment vessels at Toshiba Corp., said on Oct. 26 that the most fundamental cause of the Fukushima plant fiasco probably lay in the blind acceptance of the safety standards adopted in the United States, which did not take into consideration all potential consequences from earthquakes.

The reactors damaged at Fukushima were of the GE Mark 1 type designed and built by General Electric Co. He pointed out that in the U.S., there is no need to consider the combination of an earthquake and a loss-of-coolant accident caused by broken piping, adding that it is reasonable to assume that the earthquake and loss of coolant occurred simultaneously at Fukushima No. 1.

Perhaps it was against such a background that Tepco blacked out crucial matters in the operational manual of the reactors, as there are 10 other GE Mark 1 type reactors in Japan

Yomiuri: Former Japan PM ‘hints’ of recriticality at Fukushima — Found Chlorine-38 in Reactor No. 1 water tested at research institute

Unfortunately the issue is not available online, but Yomiuri summarizes the contents.

Hatoyama: Nationalize Fukushima N-plant, Yomiuri Shimbun, Dec. 16, 2011 (Emphasis Added):

In the Nature article, former Prime Minister Yukio Hatoyama:

1. Criticizes Tokyo Electric Power Co., the operator of the crippled plant, for disclosing only limited information to Diet committees

2. Hints at the possibility of recriticality at the plant

3. Says there is still much about the crisis that needs clarification, including the state of the molten fuel within the nuclear reactors

Hatoyama also says that he and [Tomoyuki Taira, member of the House of Representatives] obtained data on samples of contaminated water TEPCO obtained from the basement of the plant’s No. 1 reactor and asked an outside research institute to reanalyze them.

Results showed that radionuclide chlorine 38, one of the isotopes released during recriticality, “was indeed present,” he claims.

TEPCO reported at one point that it found chlorine 38 in the sampled water, but the utility later retracted that statement, saying there was a mistake in the analysis.

we need to find nature magazine..this issue is not on line I think they said..

Here's a video:  Arne Gunderson from April about recriticalizing

Fukushima accident: disaster response failed - report

December 26, 2011

"A lack of preparedness for a disaster and failures in the response to it exacerbated the effects of the nuclear accident at Japan's Fukushima plant in March, a new report says."

snip

More than 20,000 people were killed when an earthquake and tsunami struck.

Tens of thousands had to be evacuated as radiation leaked into the atmosphere, sea and food chain.

In short what they are saying is that no one thought about an eq, (this is Japan, right??) no one thought about possible tsunamis from eq(right Japan never has an eq over a 7 pointer)...no one prepared their workers or made sure they understood how to cope once the eq/tsunami/accident happened(so you have workers that are not fully schooled in how to deal with a nuclear accident, working on a nuclear site).  Also makes me wonder who knew this was the case, if anyone did??  Come on now...building nuclear plants in a well known seismic zone,then staffing it, but not training  your staff to be competent in case of an accident, sure seems like a stupid plan to me..but what do I know.

But then, it's all good...they don't really want to assign blame anyway...

from the article

"The panel said its aim was not to apportion blame for the disaster, but to learn why the accident happened in the way it did, AFP news agency reported."

Well, it happened because they built nuclear plants in a seismic zone and were not prepared for the consequences....trouble is...neither was the rest of the world
