川が新たなセシウム運ぶ 東京湾河口部汚染 本紙3回目調査 via 東京新聞

東京湾に注ぐ主要河川の河口部で、本紙が独自に堆積物を採取し放射性セシウム濃度を調べたところ、東京電力福島第一原発事故から五年半がたっても、川で運ばれてきたセシウムが新たに蓄積され、濃度はあまり低下していないことが分かった。調査は三回目。海水魚はセシウムを取り込んでも排出するため、影響は限られるとみられるが、継続的な監視は必要だ。 (原発取材班)

[…]

最も高い濃度を検出したのは、印旛沼(千葉県)につながる花見川(同)。一キログラム当たり四五二~七八九ベクレルと、他の河口より突出して高かった。基準値はないものの、原発で使ったコンクリートや金属を再利用できる基準は同一〇〇ベクレル。この値に比べ、大幅に高い。河口から七百メートルほど離れると七六ベクレルに急減していた。

[…]

 魚介類への影響がポイントになるが、水産庁が、各地の検査機関による水産物の放射能調査をまとめたデータによると、二〇一六年度は東京湾で八十一件の魚などが調べられた。うち六件でセシウムが検出されたものの、魚種はいずれもスズキで、一ベクレル未満と検出できるぎりぎりの値だった。食品基準(一〇〇ベクレル)の百分の一未満の低い水準で、食べても何ら問題のないレベルといえる。

◆水環境に流れ込む

<鎌田准教授の話> 首都圏の河川の河口では、いまだにセシウムが継続的に供給され、蓄積し続けていることが確認できた。森林域では放射性物質は土壌にとどまり、水環境には流出しにくいが、都市部では河川など水環境に流れ込みやすいことが指摘されている。

PILGRIM’S PROGRESS: INSIDE THE AMERICAN NUCLEAR-WASTE CRISIS via The New Yorker

On a mild September day in 2012, Paul Rifkin asked a friend with a helicopter to help him perform an experiment. Rifkin, a retired restaurateur turned amateur photographer, wanted to capture aerial images of Pilgrim Nuclear Power Station, which sits on the shores of Cape Cod Bay, a quick drive from his home. He had taken an interest in the facility a year and a half earlier, after an earthquake and tsunami in Fukushima, Japan, caused a series of explosions and meltdowns in three coastal reactors—all nearly identical in design to the one at Pilgrim. Rifkin had recently joined the Cape Downwinders, a group of local residents concerned about the plant’s safety, and hoped to test assertions by a Pilgrim manager that the airspace above the plant was secure. The flyover photos he snapped that day suggested it wasn’t, but they also showed something else. On the site, near the reactor building, Entergy, the facility’s owner, had broken ground on a twelve-thousand-square-foot concrete pad. Rifkin and his fellow-activists would later learn that it was intended as storage space for the plant’s accumulating radioactive waste.

Pilgrim is one of the worst-rated nuclear facilities in the United States. Ever since it generated its first kilowatt of electricity, in December of 1972, it has been beset with mechanical failures and lapses in safety. In a single four-week stretch this summer, the plant was offline for a total of fifteen days because of a malfunctioning steam-isolation valve, elevated water levels in the reactor, and other problems. For years, Pilgrim’s detractors have kept steady pressure on Entergy and state officials through local protests, a sit-in at the governor’s office, and legal action. Last October, in a partial victory for activists, the company announced plans to shutter the plant, citing the expense of keeping it running in the face of cheap, abundant natural gas and increasingly competitive “renewable-energy resources.” The reactor is scheduled to go dark on May 31, 2019.

But that won’t end Pilgrim’s saga. Come June 1st, the plant will still host more than eight hundred tons of irradiated spent fuel. Most of the waste is currently stored in a forty-foot-deep pool of water, suspended four stories aboveground, next to the reactor core. The pool, which was designed to hold eight hundred and eighty fuel assemblies, now contains more than three times that number. (A federal regulatory waiver has allowed Entergy to pack the pool more densely than originally planned, a move repeated by operators across the country.) The National Academy of Sciences has warned that if the cooling system in a plant like Pilgrim failed, there would be little time before the water in the pool boiled away and exposed the radioactive rods to air. The resulting fire, the N.A.S. and anti-nuclear watchdogs have cautioned, could send across Cape Cod and northern New England many times the amount of radioactive cesium-137 released in the Chernobyl disaster. “Pools like the one at Pilgrim Nuclear Power Station are a disaster waiting to happen,” Senator Ed Markey, a Democrat from Massachusetts, told us in an e-mail.

Australian nuclear waste dump divides tiny outback town via Aljazeera

 

Hawker, South Australia – The towering mountains of the Flinders Ranges stand imposingly against the hundreds-of-kilometres-long stretch of flat, desolate country.

While the mountains are named after the British explorer who trekked them in the early 19th century, the indigenous Adnyamathanha people have lived in the region for tens of thousands of years.

This arid and remote part of South Australia has become the unlikely centre of a heated public debate after it was named the preferred site for the country’s first nuclear waste dump.

[…]

After two previous attempts to build a waste facility fell through due to community backlash, including from nearby indigenous residents, the federal government, last year, called for landowners to nominate their personal properties. The nearby Wallerberdina cattle station was announced as the preferred site in April this year.

But not everyone is happy; the plan has angered the local Aboriginal community, and divided residents of the nearby town of Hawker.

“Every hill has a story,” traditional owner Regina McKenzie of the Adnyamathanha and Kuyani people told Al Jazeera. “This land is our past, present and future, and we don’t want a nuclear waste dump on it.”

McKenzie and roughly a dozen others live on Yappala Station, which is part of a 24,000-hectare property that was returned to Aboriginal owners by the government in 2000, to recognise their traditional ownership. The indigenous cooperative’s property spans both sides of the neighbouring Wallerberdina Station, the projected location of the nuclear waste site.

She says the proposed site will disrupt an important indigenous storyline in the area that includes an ancient travel route with a deep spiritual significance.

“This is something that is really important to us, it’s our belief system, and I believe we have the right to be protecting our sacred places,” McKenzie told Al Jazeera.

The Department of Industry, Innovation and Science, which is overseeing the project, announced this site as the preferred location among those nominated due to the community being “particularly supportive”, adding that 65 percent of those surveyed approved of the proposal going ahead (PDF).

A fading town

There are few jobs in this remote part of Australia, and Hawker is a declining town of just 250 residents. Those who remain work in cattle and sheep farming, as well tourism, an industry which sees thousands of people visiting the Flinders Ranges each year.

“People are just moving away. There isn’t much here for younger people,” Ian Carpenter, the vice-chair of the Hawker Development Board and a supporter of the nuclear waste site, told Al Jazeera. The department said the project would create at least 15 full-time jobs, and the government has also promised that $7m will be spent developing the local community and infrastructure.

“If we go back to 18 years ago, this town had 28 business; today we are down to six. So, what are we going to be in another 18 years? This could really secure the future of the town,” Carpenter said.

The cattle station where the facility is to be built, if the proposal moves forward, is co-owned by Grant Chapman, a former senator who lives in state’s capital Adelaide. Some have accused the government of a conflict of interest for choosing Chapman’s property, particularly because in 1995, he chaired a senate committee which recommended centralised nuclear waste storage.

福島で五輪野球、世界連盟が難色 「内野が芝でない」via 朝日新聞

2020年東京五輪の野球・ソフトボールの試合会場として候補に挙がる福島県内の3球場について、世界連盟(WBSC)のフラッカリ会長が、グラウンドの内野部分が芝ではなく土であることなどを理由に難色を示していることがわかった。主会場は6日からの国際オリンピック委員会(IOC)理事会で人工芝の横浜スタジアムに決まる予定だが、福島開催の決定は先送りになる可能性が高まった。

野球・ソフトボールの福島開催を巡っては、10月に来日したIOCのバッハ会長が安倍晋三首相と面会した際、復興五輪の理念から、日本の開幕戦などを東日本大震災の被災地で開催することを提案。大会組織委員会は11月上旬、福島県で一部の試合を開催することを決めていた。

フラッカリ会長も当初、福島開催に前向きな姿勢だった。だが複数の関係者によると、11月19日に県営あづま球場(福島市)と開成山野球場(郡山市)を視察し、いわきグリーンスタジアム(いわき市)を含む候補の3球場すべて、内野が土であることや、設備が貧弱なことに難色を示したという。「土のグラウンドでトップレベルの試合をするのは日本ぐらいで、国際標準は内外野ともに芝。福島県内の球場が五輪にふさわしいのか、疑問符がついた」と関係者は明かす。

福島第1原発事故 飯舘の女性自殺、東電が争う姿勢 損害賠償訴訟初弁論 /福島 via 毎日新聞

[…]

訴状によると、女性は原発事故翌月の2011年4月に飯舘村が避難指示区域に指定されたため、家族と福島市内の借り上げ住宅に避難。避難生活のストレスから家にこもりがちになり、うつ病とみられる症状を発症した。13年3月に夫の墓参りをした後、「早くお迎えに来ないかなあ」とつぶやき、翌朝、自室で首をつって死亡した。

 

 原告は「原発事故がなければ、自ら命を絶つことはなかった」と主張。一方、東電は答弁書で、原発事故と自殺の因果関係など全面的に争う姿勢を示した。具体的な主張は次回期日以降で述べるとした。【宮崎稔樹】

Swiss Reject Plan to Speed Up Exit From Nuclear Energy via Fortune

Swiss voters rejected a plan to force their government to accelerate the country’s exit from nuclear energy in a referendum Sunday, turning down an initiative that would have seen the last plant shut in 2029.

A majority of cantons (states) voted against the plan. Under Switzerland’s direct democracy system, proposals need a majority of both cantons and votes to pass.

[…]

After the Fukushima nuclear disaster in Japan, the Swiss government adopted a gradualist approach toward transitioning the country to renewable energy by 2050.

It said nuclear plants should continue to operate as long as they are deemed safe, but didn’t set a precise timetable. The government said it needs time to switch to other sources such as wind, solar and biomass energy.

[…]

“We would have liked to win, that’s clear, but 45 percent for ‘yes’ is a good result,” Regula Rytz, the Greens’ chairwoman, told SRF. The party isn’t part of Switzerland’s broad coalition government.

“The problems haven’t been resolved with this referendum Sunday,” Rytz said. “We will keep at it on safety, on financial security … and on expanding renewable energies.”

French nuclear power in ‘worst situation ever’, says former EDF director via The Guardian

 

In the week Britain exports electricity to France for first time in four years, Gérard Magnin says renewable power will match Hinkley Point C on cost.

The French nuclear industry is in its “worst situation ever” because of a spate of plant closures in France and the complexities it faces with the UK’s Hinkley Point C power station, according to a former Électricité de France director.

Gérard Magnin, who called Hinkley “very risky” when he resigned as a board member over the project in July, told the Guardian that with more than a dozen French reactors closed over safety checks and routine maintenance, circumstances for the state-owned EDF had deteriorated since he stepped down.

The closures have seen Britain this week exporting electricity to France for the first time in four years. An industry report on Tuesday also warned that the offline reactors could lead to a “tense situation” for energy supply in France, in the event of a cold snap this winter.

[…]

Magnin said that instead of backing new nuclear, the UK and France should capitalise on falling wind and solar power costs and help individuals and communities to build and run their own renewable energy projects. He founded an association of cities switching to green energy, joined the EDF board in 2014, and is now director of a renewable energy co-op in France.

“The most surprising [thing] for me is the attitude of the UK government which accepts the higher cost of electricity … in a time where the costs of renewables is decreasing dramatically,” he said. “In 10 years [when Hinkley Point C is due to be completed], the cost of renewables will have fallen again a lot.”

Of the Hinkley C design, known as the European Pressurised Reactor (EPR), Magnin said: “A lot of people in EDF have known for a long time the EPR has no future – too sophisticated, too expensive – but they assume their commitments and try to save the face of France.”

The UK’s business department conceded in September that by the time Hinkley is operational the price of electricity guaranteed to EDF will be above the comparable costs for large-scale solar and onshore windfarms. Officials argued that using renewables instead would cost more in grid upgrades and balancing the intermittent nature of wind and solar.

放射性物質含む水 作業員10人にかかる 敦賀原発2号機 via NHK News Web

福井県にある運転停止中の敦賀原子力発電所2号機で、施設の点検作業中に放射性物質を含む水が作業員10人にかかったということです。日本原子力発電によりますと、含まれる放射性物質の量は国への報告基準を下回り、作業員の被ばくはなく、周辺の環境への影響はないということです。

30日午前10時50分ごろ、福井県敦賀市にある敦賀原発2号機の原子炉補助建屋の地下にあるタンク室で、放射性物質を含む水が作業員10人にかかるトラブルがありました。

日本原電によりますと、作業員がタンクにつながる配管の弁を解体する際に、配管の中にたまっている水を抜こうと弁を緩めたところ、水が噴き出したということです。

日本原電によりますと、噴き出した水はおよそ160リットルで、水に含まれる放射性物質の量は、国への報告基準を下回っているということです。
また、作業員の被ばくはなく、周辺の環境への影響もないということです。

福島沖地震発生に、今問う。「福島第一原発」その意識に風化はなかったか? viaホウドウキョク

[…]

しかし、福島第一原発、福島第二原発では、「東日本大震災後初めて」(東京電力)地震を理由に大規模な設備の停止があった。

福島第一原発では、原子炉建屋にたまった汚染水を移送する設備を、手動により停止させた。

これは、「汚染水が津波で漏れて環境を汚染させるリスク」を防ぐためだったと東電は説明している。

福島第二原発では、3号機の燃料プールの冷却用ポンプが、水位の変動を感知して午前6時10分に自動で一時停止した。

[…]

東電が記者会見を行ったのは、3号機のポンプの再開後の午前9時だった。

東日本大震災の原発事故の際には、東電の広報の遅れや情報隠しとも思われる姿勢が、批判を浴びた。

今回、東電の広瀬社長が出張先の新潟から急きょ本店に戻ったことは評価できるが(震災時は清水社長(当時)が出張先の関西から数日間戻れず批判の的になった)、危機管理や広報の体制にゆるみが無かったのか、あらためて検証が必要であろう。

震災から5年がたち、人々は福島でいま何が行われているか、関心が薄らいでいる。

今回の地震は、あらためて福島第一原発事故の収束がいまだ途上であることに気付く機会にもなった。

廃炉が終わるのは、30〜40年後と見込まれているが、世界でどの国もやったことのないこの廃炉事業には、いったい何年かかり、どれだけの費用がかかるのか、誰もはっきりした答えを持たない。

この途方もないリスクとコストは、将来の世代に受け継がれていくことになる。
