TOKYO (Kyodo) — Around 10,000 tons of contaminated water have pooled in underground trenches around the Nos. 1 to 4 reactor buildings of the crippled Fukushima Daiichi nuclear power plant, according to the plant operator Tokyo Electric Power Company Holdings Inc.

Tokyo Electric has no immediate plan to remove the water in the trenches where cables run for the nuclear power complex devastated by the March 2011 earthquake and tsunami disaster.

Water that flew into the trenches in the wake of the huge tsunami is believed to have been mixed with highly radioactive water leaking from the basements of reactor buildings and contaminated rain water.

“Compared with around 70,000 tons of highly contaminated water that remain in the basements of the reactor buildings, (the water in the trenches) has a low level of concentration and thus poses little threat in terms of radiation exposure and the environment,” said an official of the utility known as TEPCO.

TEPCO said in a report issued in July — based on research conducted in fiscal 2015 — that it has found around 8,000 tons of toxic water in 17 locations in the trenches that connect with reactor buildings where highly radioactive water accumulates, as well as around 3,000 tons of toxic water at 11 locations in trenches that do not connect with reactor buildings.

Of the water in the trenches around the Nos. 1 to 4 reactor buildings, a removal procedure was completed by June for around 500 tons of water in a pipe that measured the highest level of radioactive cesium at 500,000 becquerels per liter.

The level of radioactive cesium in water at other locations in the trenches was mostly measured at several thousands becquerels or below.

The level in toxic water in the basements of reactor buildings has been measured at around dozens of millions becquerels at maximum.

TEPCO has said it will continue to monitor and measure the level of contamination in water in the trenches regularly and consider taking measures to remove the water in the future. But no concrete plan has been created yet.

The electricity firm has so far removed a total of around 10,000 tons of highly radioactive water at three locations in the trenches running in the seaside of the complex and completed the procedure to fill locations concerned with cement to prevent water leaks.

Still, the level of radioactive cesium remains unchecked at 40 locations in the trenches due to high radioactive levels as well as debris and other objects blocking the research operation.

Around 8,000 tons of contaminated water, including those with an extremely low level of contamination, have also been found in the trenches running around the Nos. 5 and 6 reactor buildings. The two units have lower levels of radiation doses than the Nos. 1 to 4 units as there were no nuclear meltdowns or hydrogen explosions there during the nuclear disaster.

Government subsidies to help Fukushima farmers restart operations

futta1677m.jpg

The central government plans to set up a new subsidy system to help farmers in 12 municipalities near the stricken Fukushima No. 1 nuclear plant restart their operations, according to sources.

The program represents part of the government’s efforts to promote the reconstruction of areas damaged by the March 2011 earthquake and tsunami in the Tohoku region and the subsequent meltdowns at the Tokyo Electric Power Co. nuclear station.

The government will earmark around ¥7 billion for the program under a planned supplementary budget for its special account related to the 2011 disaster, the sources said Monday.

The program will help farmers buy equipment and livestock.

A support system is already available in which the 12 municipalities in Fukushima Prefecture buy facilities and equipment such as greenhouses and tractors and lend them for free to farmers aiming to get back on their feet.

But the system is inconvenient for individuals who want to resume farming operations, because it is mainly designed for group farming and other big operations. Also, approval from local assemblies is necessary to lend out the facilities and gear.

Under the new program, the Fukushima Prefectural Government will cover 75 percent of farmers’ purchase costs for farming equipment and livestock, the sources said. The upper limit on support per farmer will likely be ¥10 million, they said.

The central government will shoulder all costs incurred by prefectural government, the sources said.

The 12 municipalities are Tamura, Minamisoma, Kawamata, Hirono, Naraha, Tomioka, Okuma, Futaba, Namie, Kawauchi, Katsurao and Iitate.

Wind and cars disperse radioactive material

By Kurumi Sugita

A remarkable documentary of the RTBF about contaminated areas, including Minami Soma in Fukushima prefecture. These areas are heavily contaminated. Nevertheless, the Japanese government makes the people return by lifting the evacuation order and stopping aid.

 

The Nos Voisins Lointains 3.11 association, exchanged messages with Mr. Ozawa, the engineer interviewed in the documentary. According to him, the most worrisome problem is the fact that black substances in the mall parking area get attached to car tires and are transported everywhere, as we can see in the documentary. The risk of radiation is thus dispersed.

On the other side of the parking area, we see collective dwellings from where children play outside, according to Mr. Owaza.

See also the video sent by Mr. Ozawa showing the wind lifting and dispersing the contaminated dust from fields now uncultivated.

 

Linens that are drying on the balcony outside are exposed to radioactive material transported by these dusty winds. Just watch at which height the dust is lifted compared to the passing car towards the end of the video. Farmers working the land inhale this dust.

With the forced return of the population this will become their daily reality.

American nuclear expert Arnie Gundersen warns: “There is a possibility that now in Fukushima recontamination is occurring.”

 

 

CCTV (Channel 17 in Burlington, Vermont), published Jun 20, 2016

Maggie Gundersen, Chiho Kaneko and Caroline Phillips of Fairewinds Energy Education discuss the nuclear risk concerns for children not only near the nuclear disaster sites of Fukushima-Dai-ichiin Japan and Chernobyl in Ukraine, formerly the Soviet Union, but globally where areas near all nuclear power plants are contaminated with radiation. Since mothers in Japan especially bear the responsibility to protect children, they experience greater hardships in an environment where just expressing one’s concern about radiation is seen as a treasonous act. Even 30 years later, the Belarus government recognizes the merits of relocating children away from radiation contaminated areas but the children of Japan are socially forced to stay put in highly contaminated areas.

Margaret Harrington, host: I know you mentioned Arnie Gundersen, the chief engineer at Fairewinds, and he said that he measured the radiation there, too. Could you talk about that a little bit?

Maggie Gundersen, Fairewinds Energy Education founder and CEO: He’s working with some other scientists who are studying — both Japanese scientists, the samples that they took, and the US scientists who are evaluating the samples — and they’re finding astronomical amounts of radiation, even in downtown Tokyo outside of METI’s door. METI is the regulatory agency over nuclear power… When he and others were downtown in Tokyo, they took samples right there in a garden right outside the door and on the front doormat, and these are really, really high samples. Frightening, because people walking in Tokyo will then be inhaling that dust. What was the film we saw from Japan that had the mothers who were in an area where kids play and run from middle school?

Caroline Phillips, Fairewinds Energy Education: It’s a fantastic video… it’s a mothers organization, they live in the Fukushima Prefecture and they’re actually using Geiger counters that have been issued by the government. They’re walking along the river [in Fukushima City.]

Maggie Gundersen: What’s so tragic about it – kids are running along dirt paths doing gym class and track and things like that and the mothers are right down in areas that are not posted and the kids can go after school and play, and people do nature hikes and stuff. And the radiation readings are horrific.

Gendai Business Online’s top ranked article is an exclusive interview with Fairewinds Chief Engineer Arnie Gundersen titled, American nuclear expert warns: “There is a possibility that now in Fukushima recontamination is occurring.” With more than 10,000 likes on Facebook, this Japanese article delves into the truth about nuclear contamination from Fukushima Daiichi as uncovered by Arnie Gundersen during his most recent trip to Japan. Fairewinds, with the help of Japanese translators, provides you with an English translation:

On a mid-February morning, just before the 5th anniversary of the triple meltdown at Fukushima Daiichi, a group of young girls in the city of Minami-Soma rode their bikes to school past a shocked and saddened pedestrian. That upset observer was Arnie Gundersen, nuclear reactor expert and Chief Engineer with Fairewinds Associates. Mr. Gundersen has 45 years of experience as a design, operations, and decommissioning nuclear engineer. He has engaged in research of the effects of the meltdown at Three Mile Island (TMI) and conducts independent research of the triple meltdown at Fukushima Daiichi. Mr. Gundersen is in ongoing conversations with both the US and Japanese media concerning the dangers of nuclear reactors and nuclear power operation. Invited by “Peace News Japan” and several other civil groups, Mr. Gundersen visited the Fukushima prefecture five years after the catastrophe at Fukushima Daiichi.

What surprised me at this visit to Japan [his third since the meltdowns] is that the decontaminated area is contaminated again,” Mr. Gundersen said while explaining why it was such as sad shock to witness the girls on their bicycles. “This was not what I had expected. I had thought that we would not find such high doses of radiation in the decontaminated area. But, sadly, our results prove otherwise.”

During his Japan visit, Mr. Gundersen collected samples of dust from the rooftop of Minami-Soma city town hall, the floor mat of a 7-Eleven convenience store, and the roadsides of Minami-Soma city. Although the official data cannot be released before the publication of formal scientific papers, it is evident that high doses of radiation, usually found in nuclear waste, was detected from these samples.

This means that highly radioactive dust is flying around the city. In other words, the decontaminated land is contaminated again. Little girls are affected by the radiation 20 times as much as adult men. The Japanese government’s standard of 20 mSv is based on exposure assessments for adult men. The girls on their bicycles are actually being affected by a radiation dose equivalent to as much as 400 mSv.”

Mr. Gundersen also pointed out that human lungs are heavily affected by internal exposures to radiation.

At this visit, I wore a radiation proof mask that can filter out 99.98% of radiation for six hours. I sent my filter to the lab, and they found a high dose of Cesium. But, unfortunately, the Japanese government only cares about the number on a Geiger counter and does not consider the internal exposure. This has resulted in a hazardous downplay of this kind of data and human lungs are affected by the serious internal exposure.”

Why is the recontamination happening? One of the reasons is that the government did not decontaminate thoroughly. Mr. Gundersen witnessed first-hand the poor decontamination of the prefecture.

In the house I visited, only half of the garden area was decontaminated because only that half fell into the category of a contaminated area. It should not be like that. The other half would be contaminated too. Furthermore, one person discovered highly radioactive dust in their driveway where decontamination had occurred. So, of course, this person notified the related offices but the related offices told them that it was not necessary to decontaminate the driveway again because it had already been done once.  It’s unbelievable. This person’s house is located near a ravine and the opposite side of the ravine is designated a non-habitable zone.”

Another reason for recontamination is that the radiation from the mountains are coming back to the city by way of wind and rain. Mr. Gundersen noted the extreme radioactive contamination of the mountains.

We tracked wild monkeys in the mountains and found a high dose of radiation in their feces. I received the meat of a wild pig as a gift and since I could not bring it back to the US [it is illegal to bring meat back to the United States from Japan], tested the meat on a Geiger counter. The meat showed 120 counts/min. I think that the Japanese government should spend more money to decontaminate the mountains but they don’t appear to have that kind of political will. I also worry that contamination in the rivers is not monitored as rain from the mountains flow down into the rivers.”

Due to the heavy radiation contamination of the mountains, vegetables grown in that area exceed the government’s standard by 1500 Bq. These vegetables were sold at the MichinoEki in Tochigi prefecture, and the bamboo shoot grown in this contaminated region was used for elementary school lunches in Utsunomiya. These school lunches contained more than twice as much radiation as the government’s standard.

Recontamination is happening due to poor decontamination and residents of Kawauchi village in Fukushima prefecture claim that the decontamination in the forests is not enough. However, the government continues to push for the end of people’s relocation and force the return to recontaminated areas.

If I had a little child, I would never let them live there,” Mr. Gundersen pointedly states.

Mr. Gundersen also found that Tokyo remains contaminated. He measured dust collected from the sidewalk in front of MITI (Ministry of International Trade and Industry) and found a high dose of radiation. That dust is in the air that will be inhaled by the visitors and athletes of the 2020 Olympic Games. Needless to say, the current residents are inhaling it every day. “Mr. Abe should not take the advice from IAEA, MITI and TEPCO seriously,” Mr. Gundersen insists. “Instead, he should have an independent organization conduct research and listen to the advice from them.”

Japan asks Pokemon GO players to stay out of Fukushima fallout zone – but yet still allows thousands to return living in contaminated land

14055176_10206787024054810_5075239012296761589_n

 

Evolution at its best! Japan asks Pokemon GO players to stay out of Fukushima fallout zone – but yet still allows thousands to return living in contaminated land.

So far, everything from car crashes to shootings have been associated with the addictive game, and countries all over the world are now trying to stop accidents before they can happen. That, you see, is why Japan is asking Niantic to remove any wild pokemon that are currently cropping up in the Fukushima fallout zone.

TEPCO has asked the developer to keep pocket monsters far, far away from the radioactive site. Obviously, they are worried about trainers stumbling upon the area in their pursuit to catch, say, a Nucleon.

Currently, Tepco has confirmed, “the Fukushima Daiichi plant, the Fukushima Daini plant and the Kashiwazaki-Kariwa plant in Niigata Prefecture,” were all scouted. Unsurprisingly, pokemon were found at all three of the sites.

Masao Uchibori, the governor of Fukushima, said it would be dangerous for trainers to enter the areas due to their radioactive nature. As such, he’s confirmed that, “the prefectural government will consider how to draw attention to this.” Beyond that, the city of Nagasaki has also asked for Niantic to remove the app’s presence from Nagasaki Peace Park, a local memorial for the victims of the 1945 atomic bombing.

A month later following the announcement though, Earthquake-stricken regions in Japan are turning to the “Pokemon Go” phenomenon to catch more tourism money.

The Iwate, Miyagi, Fukushima and Kumamoto prefectural governments said Aug. 10 they will partner with Niantic Inc., operator of the popular “Pokemon Go” smartphone app, to promote local tourism.

Money talks !

14 arrested for smuggling illegal irradiated seafood into China from waters off coast of Fukushima

14 arrested for smuggling irradiated seafood in Shandong

Customs authorities in Qingdao, East China’s Shandong Province, detained 14 people for smuggling frozen seafood from Japan, including irradiated high-end seafood from waters near Fukushima prefecture, China Central Television (CCTV) reported on Monday.

The group has smuggled over 5,000 tons of frozen seafood – including shrimp and king crab – valued at 230 million yuan ($34.5 million) into China over the past two years, according to an announcement by the Qingdao Customs District (QCD) posted on its official website on Monday.

Some of the high-end products were from Fukushima, one of 12 Japanese prefectures from which China has banned any seafood imports due to the contamination of their waters after the Fukushima nuclear accident in 2011, according to CCTV.

Before sending the products to Shandong, smugglers transferred the seafood from Hokkaido to Vietnam, where they changed the items’ packaging and altered their production dates to evade taxes and avoid quarantine, Li Fudong of the QCD Anti-Smuggling Department told CCTV.

An investigation by officers from the Anti-Smuggling Department in the neighboring city of Yantai traced some low-priced seafood on the local market to a Shandong-based import corporation that had opened branches in East China’s Fujian Province, South China’s Guangxi Zhuang Autonomous Region and Northeast China’s Liaoning Province.

Qingdao preventive officers arrested the smuggling group’s head in June after he returned to China from the US.

Most of the smuggled seafood products were sold in Beijing, Shanghai and Guangzhou, Shandong-based dzwww.com reported.

An expert from a tissue engineering and regenerative medicine research center who asked for anonymity told the Global Times on Monday that radioactive nuclear materials can cause irreversible damage to the human body at the cellular level. The expert said such radiation can even damage our DNA and may be present in the body for many years before symptoms occur.

She said that remaining nuclear material may still affect sea life in the waters surrounding the Fukushima site, even though five years have passed since the nuclear accident.

【Thyroid Cancer in Fukushima】Fukushima Thyroid Examination Under Dual Review

uop.jpg

 

Monday, August 8, 2016

Below is unofficial translation of two Fukushima Minyu articles regarding the review of the thyroid examination, published on August 8, 2016 and July 4, 2016. The August article is based on an interview of Hokuto Hoshi, Chair of Oversight Committee for the Fukushima Health Management Survey. It might be tied to this post. The July article covers the launch of an independent exploratory committee by Fukushima Pediatric Association.

Interestingly, a telephone inquiry by a concerned citizen revealed the Division of the Fukushima Health Management Survey at the Fukushima Prefectural Office was unaware of the content of the August article before its publication in newspaper. They declined to comment on the issue for the time being while contacting Oversight Committee Chair Hoshi to confirm facts and discuss the issue internally.

On September 26-27, 2016, the 5th International Expert Symposium “Chernobyl+30, Fukushima+5: Lessons and Solutions for Fukushima’s Thyroid Question” will be held in Fukushima, organized by Nippon Foundation and co-organized by Fukushima Medical University, Nagasaki University and Sasakawa Memorial Health Foundation. Judging from the symposium theme, there seems to be a rush to bring closure to the thyroid cancer issue even before the final results of the second round screening are released. A glance at the program is quite revealing.

Oversight Committee for the Fukushima Health Management Survey Plan to Review the Thyroid Examination: Reduction in Target Population Considered

August 8, 2016

Oversight Committee for the Fukushima Health Management Survey, engaged in discussion on the status of the survey to examine the health effects due to the nuclear accident, will begin discussions as early as September to consider reduction in target population as well as review of the screening procedure.

The thyroid examination that targets all residents who were age 18 or younger at the time of the accident will face a big turning point, as revealed by the Oversight Committee Chair Hokuto Hoshi in the interview with Fukushima Minyu as of August 7th.

The thyroid examination targets about 380,000 residents. Thyroid cancer cases detected by the examination are considered “unlikely to be the effect of radiation exposure at this time” by the Oversight Committee.

What lies behind starting the discussion to consider review of the examination is the concern about detection of “latent cancer” cases, which exist at a constant rate regardless of radiation exposure, by screening with high sensitivity.

Thyroid cancer is curable in many cases, and the across-the-board cancer screening is unlikely to give rise to the merit of “reduced mortality.” Thus thyroid cancer screening is not globally recommended. This has led medical providers to voice concerns that “participation in the examination alone can be detrimental to the participants.”

Under the circumstance, the Oversight Committee is expected to begin discussions on issues such as: 1) Whether residents older than age 18 should be included in the target population in the future; and 2) Whether to change the method of mass screening currently conducted in school settings which has been pointed out to interfere with the participant’s wish not to participate.

“Thyroid Examination” Should Be Reviewed: Fukushima Pediatric Association to Establish an Independent Committee

July 4, 2016

Fukushima Pediatric Association (president: Kazuhiro Ohga) adopted a general assembly statement incorporating the establishment of its own exploratory committee to consider the status of the thyroid examination on July 3, 2016 at the general meeting held in Kooriyama City. The thyroid examination, part of the Fukushima Health Management Survey that investigates health effects of the Tokyo Electric Fukushima Daiichi nuclear power plant accident, is conducted by the prefecture targeting residents who were age 18 or younger at the time of the accident. The association deems necessary to review the thyroid examination, taking a fresh look at part of it. This is the first time the association expresses the need to review the examination.

Five years have passed since the nuclear accident, a question was raised about the status of the thyroid examination mainly by pediatricians performing medical examinations on residents who are targeted for the thyroid examination.

According to the Fukushima Pediatric Association, there are 172 individuals (as of the end of March 2016) who have been diagnosed with thyroid cancer or “suspicion of cancer.” Thyroid cancer is curable in many cases, and the screening is unlikely to give rise to the merit of “reduced mortality,” while there is a mental detriment when diagnosed with cancer. Thus thyroid cancer screening is not globally recommended.

The general assembly statement referred to health worries experienced by children participating in the thyroid examination and their guardians as well as residents, stating “It is necessary to explain (the results) to the participants with care and compassion and offer an easily comprehensible explanation to residents.”

President Ohga stated, “The thyroid examination was started in order to alleviate anxiety of residents, but it is possible the examination created (new) anxieties. It is necessary to review the examination from the standpoint of the participants.”

The Exploratory Committee, comprising the association members, is scheduled to begin discussions this fall. It will take up opinions of those diagnosed with thyroid cancer and intend to set directions before next year’s general assembly. In addition, the content of the general assembly statement will be sent to the prefectural government as a request in the future.

The statement also incorporates items regarding the response to health effects on children, long-term health management, and continuing support for children and their families who are evacuated or returning.

Anti-nuclear activists’ tents forcibly removed from economy ministry premises after yearslong battle

n-nukeprotest-a-20160822-870x682.jpg

Police stand guard as Tokyo District Court officials remove tents built by anti-nuclear activists in the Kasumigaseki district of the capital at 3:59 a.m. Sunday

Tokyo District Court officials on Sunday removed activists’ tents on the economy ministry’s premises nearly five years after they were erected by anti-nuclear campaigners protesting the government’s handling of the Fukushima nuclear crisis.

The removal of the three tents — which took place before daybreak Sunday — came after the government asked the court to enforce its order to dismantle the site.

Handed down in February 2015, the order was upheld by the Tokyo High Court last October. It became final after the Supreme Court in July rejected an appeal filed by the two anti-nuclear campaigners.

The three tents were set up in September 2011 on a roughly 50-sq. meter plot of land at the economy ministry, which oversees the nuclear power industry.

The site had been used as a base to conduct anti-nuclear activities outside the ministry after the March 2011 triple meltdown at the Fukushima No. 1 power plant, with activists uploading live video footage online, staging a hunger strike and forming human chains.

The forcible removal by court officials took place in the early hours of Sunday, a time when there were few passers-by.

About 10 citizens, including some who were staying in the tents overnight, protested as officials fenced off the encampment and blocked the road around the premises before dismantling the tents.

The government is pushing through the reactivation of nuclear power plants without taking responsibility (for the Fukushima crisis),” said a 53-year-old company employee who had been staying in one of the tents on Saturdays since the first one was erected in September 2011.

We will carry on with our protests,” he added.

In its ruling last year, the Tokyo District Court also ordered the activists to pay roughly ¥21,000 ($209) per day in fees for using the land for as long as they remained at the site. The unpaid amount has now totaled more than ¥30 million.

The district court said that while it “understands the campaigners’ compelling motive to join anti-nuclear activities after the atomic accident” that affected many people, they “do not have special rights to use the land” belonging to the Ministry of Economy, Trade and Industry in the capital.

State funds planned for cleaning heavily contaminated zones in Fukushima

Privatized profit, socialized risk and clean up

b-yenbills-a-20160408-870x581.jpg

 

The government plans to use state funds to finance the radiation cleanup in the areas most seriously contaminated by the Fukushima disaster in 2011, government sources said Friday.

It is the first plan to decontaminate the “difficult to return to” zones, including a large portion of the two towns hosting the crippled Fukushima No. 1 nuclear power plant and parts of other nearby municipalities in the prefecture.

The move is intended to expedite the cleanup process but may draw criticism because it will effectively reduce the financial burden on Tokyo Electric Power Company Holdings Inc., the utility responsible for the world’s worst nuclear crisis since Chernobyl.

Under the current legal framework, the decontamination costs are first shouldered by the state, with Tepco told to reimburse the expenses over time. But since the costs are expected to far exceed the ¥2.5 trillion estimated earlier, the utility has requested more financial support.

The government plans to conduct decontamination in the difficult-to-return-to zones, which comprise about 337 sq. km of land where around 24,000 people used to live, the sources said.

The work within the designated “reconstruction bases” will include removing buildings, replacing soil and paving roads.

Tepco will only be asked to shoulder the costs of cleaning existing facilities and infrastructure that will continue to be used within the reconstruction bases.

The government hopes to officially endorse the plan this month, the sources said.

The Fukushima disaster, triggered by a huge earthquake and tsunami in March 2011, prompted the government to issue evacuation orders to 11 municipalities near the plant.

The areas have been reclassified into three categories based on radiation level — a zone where evacuation orders are ready to be lifted, a zone where human habitation is restricted, and a zone where residents will have difficulty coming back to for a long time.

The areas subject to evacuation are gradually being reduced, with the government setting a goal of lifting all the remaining orders apart from the difficult-to-return-to zones by next March.

In the heavily contaminated zones, the government plans to conduct costly and intensive radiation cleanup efforts that will allow it to lift the evacuation orders in five years’ time.

‘99% effective’ Fukushima ice wall fails to seal off crippled nuclear plant

« TEPCO has been repeatedly facing criticism for handling of the Fukushima crisis which occurred after a massive earthquake and subsequent tsunami led to a meltdown of reactors at the facility in March 2011.

The company has admitted that it did not act properly during the disaster, confessing in February that it announced the nuclear meltdowns far too late. It also stated in a 2012 report that it downplayed safety risks caused by the incident, out of fear that additional measures would lead to a shutdown of the plant and further fuel public anxiety and anti-nuclear campaigns. »

57b7a366c36188fc458b456f.jpg

 

An “almost” watertight ice wall built around the Fukushima nuclear plant in a bid to prevent groundwater from entering the site has, quite predictably, proven to be not good enough, with Japan’s nuclear watchdog now urging TEPCO to find a better solution.

An expert panel with the Japanese Nuclear Regulation Authority examined the latest TEPCO report this week to assess how far and how successfully the project had been implemented, Japanese newspaper Asahi Shimbun reports. The members of the panel concluded that the ice wall was not working and a new plan was necessary to prevent groundwater getting mixed up with radioactive substances. 

The plan to block groundwater with a frozen wall of earth is failing,” said Yoshinori Kitsutaka, a panel member and a professor of engineering at Tokyo Metropolitan University.

They need to come up with another solution, even if they keep going forward with the plan.”

In March, construction company Kajima Corp. began building the frozen wall of earth around the four damaged nuclear reactors and has completed most of the 1.5-km (1 mile) barrier. TEPCO hoped that the frozen earth barrier would thwart most of the groundwater from reaching the plant and divert it into the ocean instead. However, little or no success was recorded in the wall’s ability to block the groundwater during the five-month-period. The amount of groundwater reaching the plant has not changed after the wall was built, experts said.

The problem is said to lie in the wall’s gaps, or parts where the barrier is not frozen. According to TEPCO, 99 percent of their thermometer readings showed that the wall’s temperatures are at or below the freezing point, meaning the wall is mostly solid. However, a remaining one percent of the readings showed temperatures above the freezing point, which means the wall is not solid at those parts.

Those constitute a mere one percent of the 820-meter-long barrier, but these sections, where the earth is not frozen, are enough to ruin the entire project as they were found in areas with high levels of groundwater concentration.

TEPCO however believes that the unfrozen sections can be fixed if coated with concrete.

In April a chief architect of the project said that gaps in the wall and rainfall will still allow for water to creep into the facility and reach the damaged nuclear reactors, which will in turn create as much as 50 tons of contaminated water each day.

It’s not zero,” Yuichi Okamura, a general manager at Tokyo Electric Power Co. (TEPCO) said referring to the amount of groundwater flowing into the plant. “It’s a vicious cycle, like a cat-and-mouse game…we have come up against many unexpected problems.”

TEPCO has been repeatedly facing criticism for handling of the Fukushima crisis which occurred after a massive earthquake and subsequent tsunami led to a meltdown of reactors at the facility in March 2011.

The company has admitted that it did not act properly during the disaster, confessing in February that it announced the nuclear meltdowns far too late. It also stated in a 2012 report that it downplayed safety risks caused by the incident, out of fear that additional measures would lead to a shutdown of the plant and further fuel public anxiety and anti-nuclear campaigns.

Despite the ongoing problems encountered following the meltdowns, TEPCO has set 2020 as the goal for ending the plant’s water problem – an aim which critics say is far too optimistic. The problem of water contamination is just one of many surrounding the dismantling and containing of the Fukushima plant debris which is estimated to take at least 40 years.

Worker’s leukemia deemed result of his work at Fukushima Daiichi Nuclear plant granted compensation

Man’s leukemia deemed result of his work at Fukushima plant

The labor ministry said a man who developed leukemia by helping in clean-up efforts at the crippled Fukushima No. 1 nuclear power plant is entitled to work-related compensation.

It marks the second such case since the 2011 nuclear disaster.

The Ministry of Health, Labor and Welfare recognized that the cancer was due to exposure to radiation at the facility and said the government will cover his medical expenses.

The ministry said Aug. 19 that the man, who is in his 50s, was involved in removing debris and repairing machinery that handled radioactive water at the plant between April 2011, a month after the triple meltdown triggered by the earthquake and tsunami disaster, and January 2015.

His accumulative radiation exposure was 54.4 millisieverts.

The man worked for a contractor with Tokyo Electric Power Co., the operator of the nuclear complex.

He was diagnosed with leukemia in January 2015, and filed application for worker’s accident compensation at the Fukushima Labor Standards Inspection Office, a regional branch of the ministry.

Under the ministry’s guidelines, eligibility for work-related compensation in such cases is granted if leukemia is diagnosed after the person worked for more than a year in an assignment which resulted in an annual dose of more than 5 millisieverts.

The ministry’s decision to grant compensation in this case came after a panel of experts offered their opinions on the matter.

The ministry is scrutinizing the cases of five other former workers at the plant who have applied for compensation.

Compensation in such cases was first granted last October after a man in his early 40s was diagnosed with leukemia in January 2014. He was exposed to 16 millisieverts of radiation while he worked at the plant between 2012 and 2013.

Applications for the work-related compensation as a result of the Fukushima disaster are expected to increase in coming years, experts say.

According to TEPCO, those who had annual does of more than 5 millisieverts of radiation during fiscal 2015 numbered 4,952.

Fukushima worker with cancer granted compensation

Japan’s labor ministry has certified that a former worker at the Fukushima Daiichi nuclear plant is eligible for compensation for developing leukemia.
The man in his 50s had worked at the plant for nearly 4 years since April 2011, soon after the compound suffered a meltdown.
The ministry says the man was in charge of mechanical repairs at the plant. It says he developed leukemia in January last year, and applied for workers’ compensation.
Ministry officials say the man’s radiation exposure has reached 54.4 millisieverts, and that they found no other plausible causes except his work.
He is the 2nd person to be awarded compensation in connection with the accident, following a case last October involving another man with leukemia.
In all, 14 nuclear plant workers in Japan have been granted compensation for work-related cancer.
About 47,000 people have worked at the Fukushima plant in the 5 years since the accident.

Panel: TEPCO’s ‘ice wall’ failing at Fukushima nuclear plant

bbnm,.jpg

Devices to freeze the earth are set up on the southern side of the No. 4 reactor building at Tokyo Electric Power Co.’s Fukushima No. 1 nuclear power plant in Fukushima Prefecture in 2014.

Tokyo Electric Power Co.’s “frozen wall of earth” has failed to prevent groundwater from entering the crippled Fukushima No. 1 nuclear plant, and the utility needs a new plan to address the problem, experts said.

An expert panel with the Nuclear Regulation Authority received a report from TEPCO on the current state of the project on Aug. 18. The experts said the ice wall project, almost in its fifth month, has shown little or no success.

The plan to block groundwater with a frozen wall of earth is failing,” said panel member Yoshinori Kitsutaka, a professor of engineering at Tokyo Metropolitan University. “They need to come up with another solution, even if they keep going forward with the plan.”

One big problem hampering work at the nuclear plant, which was hit by the Great East Japan Earthquake and tsunami in 2011, has been the tons of groundwater entering the buildings housing the No. 1 through No. 4 reactors every day.

The water becomes contaminated with radioactive materials within the reactor buildings.

TEPCO’s plan was to create a frozen wall of earth around the reactor buildings to divert the groundwater away from the plant and into the ocean.

The company started freezing the ground on March 31, and the project’s budget was 34.5 billion yen ($344 million) in taxpayer money as of the end of May.

But the amount of groundwater pumped from the ocean side of the frozen wall has shown little change from when there was no icy earth wall.

TEPCO’s report said 99 percent of thermometer readings on the 820-meter-long stretch showed temperatures of freezing or lower, suggesting the underground wall was frozen solid at those points.

However, the remaining 1 percent of the readings above freezing were in areas with high levels of groundwater concentration.

A 99-percent success rate may sound impressive, but much like dams, airlocks and Tupperware, TEPCO’s ice wall is failing if it is not 100-percent watertight.

The utility said the unfrozen sections could be reinforced with an injection of concrete.

The panel asked the utility submit calculations estimating the amount of groundwater that can be blocked if water is pumped before it reaches the frozen wall.

Footholds Should Be Built in Fukushima No-Go Zone: LDP Team

evacuation_orders_and_restricted_areas_4.jpg

Tokyo, Aug. 17 (Jiji Press)–Reconstruction footholds should be set up in the no-go zone heavily contaminated by the 2011 nuclear accident in Fukushima Prefecture in northeastern Japan, a Liberal Democratic Party team proposed Wednesday.


The footholds should be used for decontamination work and infrastructure development so that evacuation orders for residents of the zone will be lifted in around five years, said the ruling party’s Headquarters for Accelerating Reconstruction after the Great East Japan Earthquake.


At a general meeting, the headquarters broadly agreed on a draft outline of the party’s planned sixth reconstruction proposal for areas damaged by the March 2011 earthquake and tsunami and the subsequent reactor meltdowns at Tokyo Electric Power Company Holdings Inc.’s Fukushima No. 1 nuclear power plant.


The government plans to remove all evacuation advisories in municipalities affected by the nuclear accident by the end of March 2017, excluding in the no-go zone where radiation levels are still too high for local residents to return home anytime soon.


The LDP will submit the proposal to Prime Minister Shinzo Abe later this month, after finalizing it through discussions with its coalition partner, Komeito.
