TEPCO ordered to pay for ‘false rumors’ from Fukushima crisis via The Asahi Shimbun

A court ordered Tokyo Electric Power Co. to pay compensation to a golf course operator for lost revenue caused by “false rumors” from the disaster at the utility’s Fukushima No. 1 nuclear power plant.

Although TEPCO argued that the golf course in northern Tochigi Prefecture, 115 kilometers from the nuclear plant, was safe from radiation exposure, the Tokyo District Court on July 20 said TEPCO must still cover 19.6 million yen ($183,000) of the golf course operator’s losses in 2011.

“This is an epoch-making judgment that appropriately recognizes damages caused by false rumors,” said Kiyohisa Arai, the lawyer who represented the golf course operator.

The plaintiffs, who demanded 86.4 million yen in compensation, argued that the triple meltdown at the Fukushima plant in March 2011 led to a prolonged decline in customers.

According to the ruling, sales at the golf course in March 2011 plummeted 62 percent compared with the figure for March 2010, and monthly revenues continued to decline year-on-year.

TEPCO argued that “the golf course was located far away from the power plant, and there were no concerns of being exposed to radiation there.”

Tochigi Prefecture lies south of Fukushima Prefecture, where the stricken nuclear plant is located.

However, the court ruled that rumors were enough to keep customers away from the golf course in the six months following the nuclear accident.

THREE-YEAR RETENTION OF RADIOACTIVE CAESIUM IN THE BODY OF TEPCO WORKERS INVOLVED IN THE FUKUSHIMA DAIICHI NUCLEAR POWER STATION ACCIDENT via Radiation Protection Dosimetry

Abstract

Direct measurements of seven highly exposed workers at the Tokyo Electric Power Company Fukushima Daiichi Nuclear Power Station accident have been performed continuously since June 2011. Caesium clearance in the monitored workers is in agreement with the biokinetic models proposed by the International Commission on Radiological Protection. After 500 d from the initial measurement, however, the caesium clearance slowed. It was thought to be unlikely that additional Cs intake had occurred after the initial intake, as activity in foods was kept low. And, the contribution from the detector over the chest was enhanced with time. This indicates that insoluble Cs particles were inhaled and a long metabolic rate showed.

Greenpeace reports jump in radioactive contamination in Fukushima waterways via The Japan Times

Greenpeace Japan on Thursday said it has discovered radioactive contamination in Fukushima’s riverbanks, estuaries and coastal waters at a scale hundreds of times higher than pre-2011 levels.

One sample of sediment taken along the Niida River, less than 30 km northwest of the crippled Fukushima No. 1 power plant, revealed the presence of cesium-134 and cesium-137 at levels of 29,800 becquerels per kilogram.

That was just one of 19 samples of dried sediment and soil the environmental activist group took and analyzed from the banks of the Abukuma, Niida, and Ota rivers. The samples were collected by Greenpeace in February and March.

All of the samples but one exhibited more than 1,000 Bq/kg of radioactive material. The lowest level, 309 Bq/kg, was logged at a spot along the Abukuma River.

Cesium-134 has a half-life of about two years, but cesium-137 has a half-life of 30 years and is considered particularly hazardous. The standard limits set for radioactive cesium in Japan are 100 Bq/kg for general foods and 10 Bq/kg for drinking water.

[…]

Greenpeace Japan also published the results of tests on dried marine sediment samples collected at 25 points off the Fukushima coastal area, including three river estuaries, during this same period, at depths of between 7.4 and 30.6 meters. The results showed that the highest level of cesium was 144 Bq/kg taken from a sample collected off the coast from the Fukushima power plant, while the lowest total cesium figure was 6.5 Bq/kg off Nakanosaku, well to the south of the plant.

In addition to Fukushima, Greenpeace Japan took dried sediment samples from Lake Biwa at three locations near the shore. The results showed cesium levels to be between 7.1 Bq/kg and 13 Bq/kg at two locations, and negligible at the other two.

2016/07/21 放射線調査結果:福島の川岸の汚染、琵琶湖の最大2千倍—— 福島から関西への教訓、『水に沈む放射能』レポート発表 via Greenpeace

国際環境 NGO グリーンピース・ジャパンは本日、宮城県の阿武隈川河口および福島県の沿岸と複数の河川の流域で2月21日から3月11日に実施した放射線測定と堆積物サ ンプリング調査の結果を発表しました。比較のために、3月22日から24日には関西電力の複数の原発から数十キロに位置する琵琶湖の堆積物も調査しまし た。その結果、阿武隈川(源流と主な集水域は福島県、河口は宮城県)、新田川、太田川の川岸は放射性セシウムによって高濃度に汚染され、最大で琵琶湖沿岸 の堆積物の約2,000倍も汚染されていることがわかりました。グリーンピースは、これらの結果をレポート『水に沈む放射能:東京電力福島第一原発事故か ら5年 淡水域および海水域の堆積物に対する放射能調査と分析』(注1)にまとめ発表しました。

グリーンピース放射線調査チームは、琵琶湖岸の高島、長浜、 草津の4カ所(内、長浜で2カ所)で調査を行いました。その中で、最も汚染度が高いサンプルは長浜市の湖岸で採取した堆積物で、放射性セシウム(セシウム 137,セシウム134合計)13Bq/kgが検出されました。一方、福島県では相馬郡新田川沿岸で採取した堆積物のサンプルの汚染度が最も高く、琵琶湖 岸のものと比べ2,000倍の29,800Bq/kgが検出されました。同サンプルは、福島県内の他の河川で採取したサンプルと同様、避難区域外で採取し たものです。なお、琵琶湖の汚染は核実験とチェルノブイリ原発事故の影響と考えられます。

グリーンピースのグローバルシニアエネルギー担当のケンドラ・ウルリッチは「高濃度に汚染さ れた福島の森林、河川、湖は、今後数十年から数百年は汚染されたままです。放射性物質は降雨や風によって循環し続けることから、森林や淡水系は放射能の供 給源となり続けます。これは琵琶湖にとって重要な教訓です」と警告しました。

グリーンピースによる福島原発沿岸の海底調査で測定された堆積物は、最も汚染度が高いもので120Bq/kgで、2010年の測定値0.23〜0.26Bq/kg(注2)に対し、いまだ数百倍です。

もんじゅ「動かすことが前提」 馳浩文科相「廃炉という選択肢はまったくない」via 朝日新聞

馳浩文部科学相は20日、朝日新聞のインタビューに応じ、原子力規制委員会から見直し勧告を受けた高速増殖原型炉「もんじゅ」について「廃炉という選択肢は現段階でまったくない」と述べた。馳氏は「動かすことが前提」とも語り、勧告に従って運営主体を変更し、研究計画通り発電と高レベル廃棄物に含まれる放射性物質の半減期を短くする研究に取り組む施設として維持する考えを示した。

新主体の選定状況を馳氏は「経産省外務省、官邸などとの調整が必要だが、今がどの段階かは言えない」として明言を避けた。

<除染土再利用>疑問山積 専門家からも異議via河北新報

 東京電力福島第1原発事故に伴う福島県内の除染土を全国の公共工事で再利用する環境省の方針に疑問の声が上がっている。国は事故前、原発の廃炉で出る廃棄物の再利用基準を「1キログラム当たり100ベクレル以下」と定めたが、今回は80倍に当たる「同8千ベクレル以下」とする基準を新たに設けた。同省は「コンクリートや土で覆い、適切に管理すれば100ベクレル以下と同程度の被ばく線量に抑えられる」としているが、受け入れが進むかは不透明だ。
[…]
基準を高くすればそれだけ再利用できる量は増え、8千ベクレル以下の場合、技術的には99%以上、再利用できる計算だ。ただ、実際には100ベクレル以下の基準をクリアした廃炉廃棄物さえ一般の受け入れは進んでおらず、いまだ原子力施設内でのブロックや遮蔽材への利用にとどまっている。
 環境省が「8千ベクレル以下」の基準案を示した3月末以降、原子力規制委員会の田中俊一委員長が記者会見で「一般論として見れば、同じ放射能で汚染されたものが、(扱いが)違うということはよくない」と異議を唱えたほか、環境保護団体「FoEジャパン」は「環境汚染を防ぐことはできない」として方針の撤回を求める約1万5千人分の署名を提出するなど波紋が広がったが、環境省は6月末、正式決定に踏み切った。
 環境省は再利用の対象を日本全国としているが、同省幹部は「福島県外での利用は地元の強い反発が予想され、現時点では現実的ではない。県内の実証事業を通じて安全に管理する方法を確立し、理解を広めていきたい」と打ち明けた。

Watchdog suit seeks to nullify LANL cleanup deal via The Santa Fe New Mexican

A Santa Fe-based watchdog group is asking a federal court to declare invalid a new consent order governing cleanup of Cold War-era waste at the Los Alamos National Laboratory, saying regulators have failed to meet their public participation requirements.
At issue is a settlement agreement between the lab, the federal government and the state to clean up hazardous waste, the legacy of decades of nuclear weapons and chemical research.
In June, the New Mexico Environment Department released a revised version of the 10-year-old consent order, which officials said would expedite cleanup and increase funding for the program.
But in a statement Tuesday, Nuclear Watch New Mexico said the new consent order is not enforceable because it creates a “giant loophole” that would allow the U.S. Department of Energy and LANL to avoid cleanup by claiming it is “either too expensive or impractical.”
The group also says that the consent order absolves the Energy Department and Los Alamos Nuclear Security LLC, the consortium that operates the lab, of past violations.
[…]
The original 2005 consent order included specific guidelines on how and when the waste had to be removed from the lab. But last November, Environment Secretary Ryan Flynn said existing cleanup goals were unrealistic, in part due to the closure of the Waste Isolation Pilot Plant in Carlsbad, which has not accepted new waste since radiation leaked from a improperly packaged drum in February 2014.
As a result, Nuclear Watch New Mexico filed a lawsuit against the lab and the federal government in May for failing to meet the deadlines set in the consent order. It said the state could have collected more than $300 million in penalties if the government had been held accountable for those missed deadlines.
Nuke Watch says the parties initially agreed to “rigorous public participation requirements and a detailed cleanup schedule” in the 2005 consent order, and these requirements should still be enforced.
“We will continue to push for the public to have a true voice in these important matters,” Scott Kovac, research director of the group, said in a statement.

‘The graveyard of the Earth’: inside City 40, Russia’s deadly nuclear secret via the Guardian

Ozersk, codenamed City 40, was the birthplace of the Soviet nuclear weapons programme. Now it is one of the most contaminated places on the planet – so why do so many residents still view it as a fenced-in paradise?

[…]

Deep in the vast forests of Russia’s Ural mountains lies the forbidden city of Ozersk. Behind guarded gates and barbed wire fences stands a beautiful enigma – a hypnotic place that seems to exist in a different dimension.

Codenamed City 40, Ozersk was the birthplace of the Soviet nuclear weapons programme after the second world war. For decades, this city of 100,000 people did not appear on any maps, and its inhabitants’ identities were erased from the Soviet census.

Today, with its beautiful lakes, perfumed flowers and picturesque tree-lined streets, Ozersk resembles a suburban 1950s American town – like one of those too-perfect places depicted in The Twilight Zone.

[…]

The city’s residents know the truth, however: that their water is contaminated, their mushrooms and berries are poisoned, and their children may be sick. Ozersk and the surrounding region is one of the most contaminated places on the planet, referred to by some as the “graveyard of the Earth”.

Yet the majority of residents do not want to leave. They believe they are Russia’s “chosen ones”, and even take pride in being citizens of a closed city. This is where they were born, got married, and raised their families. It is where they buried their parents, and some of their sons and daughters too.

‘Saviours of the world’

In 1946, the Soviets began construction of City 40 in total secrecy, around the huge Mayak nuclear plant on the shores of Lake Irtyash. It would house the workers and scientists transported from across the country to lead the Soviet Union’s nuclear weapons programme, and build an atomic bomb.

For the first eight years, residents were forbidden from leaving the city, writing letters or making any contact with the outside world – including members of their own family. Those who had been relocated here were considered missing by their relatives, as if they had disappeared into oblivion.

City 40’s inhabitants were told they were “the nuclear shield and saviours of the world”, and that everyone on the outside was an enemy. While the majority of the Soviet population were suffering from famine and living in abject poverty, the authorities created a paradise for these residents, providing them with lives of privilege and some luxury.

They were offered private apartments, plenty of food – including exotic delicacies such as bananas, condensed milk and caviar – good schools and healthcare, a plethora of entertainment and cultural activities, all in a lakeside forest setting worthy of a Hans Christian Andersen fairytale.

In exchange, the residents were ordered to maintain secrets about their lives and work. It is a deal they still adhere to today, in a city where almost all of Russia’s reserve fissile material is stored.

[…]

City 40 residents have been casualties in a number of nuclear incidents, including the 1957 Kyshtym disaster – the world’s worst nuclear accident prior to Chernobyl – which the Soviet authorities kept a well-guarded secret from the outside world.

The Mayak plant’s management has also overseen the dumping of its waste into nearby lakes and rivers, which flow into the River Ob and on into the Arctic Ocean. Over four decades, Mayak is said to have dumped 200 million curies of radioactive waste into the environment, equal to four “Chernobyls”, although this is always denied by the authorities.

According to some Ozersk residents, the dumping continues today. One of the nearby lakes has been so heavily contaminated by plutonium that locals have renamed it the “Lake of Death” or “Plutonium Lake”. The radioactive concentration there is reported to exceed 120 million curies2.5 times the amount of radiation released in Chernobyl.

In a village about 20 minutes outside Ozersk, a digital clock in the town square switches constantly between the local time and the current level of radiation in the air (though the latter reading is never accurate). Half a million people in Ozersk and its surrounding area are said to have been exposed to five times as much radiation as those living in the areas of Ukraine affected by the Chernobyl nuclear accident.

[…]

Samira Goetschel is an award-winning filmmaker based in Los Angeles. She is the producer and director of the feature-length documentary City 40, which will be screened at Bertha DocHouse, London WC1, on 23 July, and will be available on Netflix from September

東電「完全凍結は困難」 第一原発凍土遮水壁 規制委会合で見解 via 福島民報

東京電力は19日、福島第一原発の凍土遮水壁について、完全に凍結させることは難しいとの見解を明らかにした。同日、都内で開かれた原子力規制委員会の有 識者会合で東電の担当者が示した。東電はこれまで、最終的に100%凍結させる「完全閉合」を目指すとしていた。方針転換とも取れる内容で、県や地元市町 村が反発している。

(略)

凍土壁は1~4号機の周囲約1.5キロの地中を凍らせ、建屋への地下水の流入を抑え、汚染水の発生量を減らす計画。
東電は3月末に一部で凍結を始めたが、一部で地中の温度が下がらず追加工事を実施した。東電によると、第一原発海側の一日当たりの地下水くみ上げ量は6月が平均321トン。5月の352トンに比べ31トン減少したが、凍土壁の十分な効果は確認できていない。

(略)

福島第一原発が立地する双葉町の伊沢史朗町長も「公式の場で方針転換とも取られかねない発言を唐突にする東電の姿勢には、非常に違和感を感じる」と指摘 した。双葉地方町村会長の馬場有浪江町長は「凍土壁で汚染水を完全に管理できるという説明だったはず。町民の帰還意欲にも影響しかねない問題だ」と批判し た。
一方、東電は「地下水流入量抑制が目的で、100%閉合を確実に実施するわけではない。目的は変わっておらず方針転換ではない」(本店広報室)としている。

TEPCO told to solve problem of harmful water at Fukushima plant via The Asahi Shimbun

The nation’s nuclear watchdog exhorted Tokyo Electric Power Co. to do something about the accumulation of tens of thousands of tons of highly radioactive water at the stricken Fukushima No. 1 nuclear plant, calling the situation intolerable.

“We cannot allow the danger of highly polluted water at the plant to continue any longer,” Toyoshi Fuketa, a commissioner of the Nuclear Regulation Authority, said at a July 19 meeting to discuss work on the plant’s decommissioning.

Fuketa urged TEPCO to consider pumping the highly radioactive water or diluting it, citing the risk of spill if another tsunami hits.

About 60,000 tons of water containing extremely high levels of radiation have accumulated in the basements of the No. 1 through No. 4 reactor and turbine buildings.

Water leaking to the basement floors of the facilities after being used to cool melted nuclear fuel at the plant has mixed with underground water flowing there.

The concentration of radioactive cesium is estimated at between hundreds of thousands becquerels and tens of millions of becquerels per liter.

[…]

The company has been trying to reduce the volume of contaminated water by building a frozen underground wall around the reactor and turbine buildings. The frozen soil wall was expected to prevent groundwater from flowing into the plant.

TEPCO started the freezing of the soil in late March, but not all of the wall is in an ice state, with the result that a huge volume of groundwater is still flowing to the nuclear complex.
