<原発避難>支援求め直訴状 知事面会応じずvia 河北新報

福島県が東京電力福島第1原発事故に伴う自主避難者への住宅無償提供を来年3月で打ち切る方針を巡り、被災者を支援する「原発事故被害者団体連絡会」などは28日、方針撤回を内堀雅雄知事に直接訴える行動を起こした。
内堀知事は直訴状を持参した支援者との面会に応じず、県庁内で知事に「県民の声を聞いて」と大声が浴びせられる場面もあった。支援団体は12月2日まで連日、直訴状を手に県庁を訪れ、面会を求める方針。

[…]

支援者の前を無言で通り、定例記者会見に臨んだ内堀知事は「組織全体で丁寧に対応する」と従来の説明を繰り返した。
知事との面会は複数の支援団体が求めている。記者会見した連絡会の武藤類子共同代表は「県の態度は冷たく残念だ」と語った。
県によると、県内外で暮らす避難者のうち、約1万2500世帯が住宅無償提供の打ち切り対象となる見通し。県は打ち切り後、所得制限を設けて家賃を補助する方針で、約2000世帯が対象と見込んでいる。

停止中の女川原発1号機、原子炉建屋に海水12トン超 via 朝日新聞

東北電力は28日、運転停止中の女川原発(宮城県)の1号機で、原子炉建屋に海水約12・5トンがあふれ出したと発表した。機器の点検を終えて冷却用の海水の通水を再開したところ、本来は閉じているべき弁が開いていたため、海水が建屋内に流れ込んだ。海水に放射性物質は含まれておらず、すべて回収された。外部への流出はないという。

東北電によると28日午前10時56分ごろ、原子炉建屋の地下2階で海水があふれ出ているのを、作業員が発見した。当時、原子炉格納容器の空調や使用済み燃料プールの浄化に使用するポンプなどを冷却する熱交換器の点検をしていた。点検を終えて冷却用の海水を流したところ、閉じているべき弁が開いていたため、海水が本来とは異なる配管に流れ込み、建屋内にあふれ出たという。

<福島原発事故>廃炉・賠償20兆円へ 従来想定の2倍via YAHOO!ニュース

[…]

政府の従来の想定は、賠償=5.4兆円▽除染=2.5兆円▽汚染土を保管する中間貯蔵施設の整備=1.1兆円▽廃炉=2兆円の計11兆円となっていた。

新たな試算は、賠償が約8兆円、除染が4兆~5兆円程度に膨らむ見通し。廃炉も従来の2兆円が数兆円規模で拡大する公算が大きい。中間貯蔵施設の整備費は変わらないが、全体では20兆円を上回る見込みとなった。

政府の従来想定は2013年末時点に見積もったが、賠償や除染の対象が増加している。廃炉も原発内に溶け落ちた核燃料(燃料デブリ)の取り出し費用などが拡大。経産省は既に現状で年800億円の費用が年数千億円程度に達するとの試算を明らかにしている。

費用の工面について、政府はこれまで、賠償は国の原子力損害賠償・廃炉等支援機構がいったん立て替え、東電を中心に大手電力が最終的に負担金を支払い▽除染は国が保有する東電株の売却益を充当▽中間貯蔵施設は電源開発促進税を投入▽廃炉は東電が準備--との枠組みを示してきた。

政府は、賠償費の増加分について、原子力損害賠償・廃炉等支援機構の立て替え増額を検討。これとは別に、大手電力や新電力が送電会社の送電線を利用する料金への上乗せも検討している。この料金は政府の認可制となっており、最終的に電気料金に転嫁される。

Worker falling into Hanford septic tank leads to fine via Tri-City Herald

A Hanford contractor will pay a fine after one of its subcontractor’s employees fell into a liquid-filled, abandoned septic tank at the nuclear reservation.

Washington River Protection Solutions has agreed to a consent order requiring it to pay the Department of Energy $45,000 and improve safety and response processes. The DOE Office of Enforcement investigated the incident.

Questions were raised, including about a delay in calling for an emergency response.

 

Three construction workers with American Electric Inc. were digging by hand to locate an out-of-service septic tank in the AX Tank Farm in central Hanford on Jan. 21, according to the consent order. The tank farm has underground tanks of radioactive waste, with the septic tank part of the support infrastructure for work.

All three were wearing protective clothing and were carrying tanks with a one-hour supply for their supplied air respirators.

As the workers dug, part of the top of the tank collapsed.

Kansai Electric Power : Fukushima aftershock renews public concern about restarting Kansai’s aging nuclear reactors via 4 Traders

 

Kansai Electric Power : Fukushima aftershock renews public concern about restarting Kansai’s aging nuclear reactors

Nov. 27–KYOTO — The magnitude-7.4 aftershock that rocked Fukushima Prefecture and its vicinity last week, more than five years after the mega-quake and tsunami of March 2011, triggered fresh nuclear concerns in the Kansai region, which hosts Kansai Electric Power Co.’sMihama plant in Fukui Prefecture.

The aftershock came as the Nuclear Regulation Authority approved a two-decade extension for Mihama’s No. 3 reactor on Nov. 16, allowing it and two others that have already been approved to run for as long as 60 years to provide electricity to the Kansai region.

Residents need to live with the fact that they are close to the Fukui reactors, which are at least 40 years old. Despite reassurances by Kepco, its operator, and the nuclear watchdog, worries remain over what would happen if an earthquake similar to the one in 2011, or even last week, hit the Kansai region.

[…]

n a scenario put together by Kyoto Prefecture three years ago, it was predicted that tens of thousands of people would take to available roads in the event of an nuclear accident. A 100 percent evacuation of everyone within 30 km of a stricken Fukui plant was estimated to take between 15 and 29 hours, depending on how much damage there was to the transportation infrastructure.

But Kansai-based anti-nuclear activists have criticized local evacuation plans as being unrealistic for several reasons.

First, they note that the region around the plants gets a lot of snow in the winter, which could render roads, even if still intact after a quake or other disaster, much more difficult to navigate, slowing evacuations even further.

Second is the radiation screening process that has been announced in official local plans drawn up by Kyoto and Hyogo prefectures.

While automobiles would be stopped at various checkpoints along the roads leading out of Fukui and given radiation tests, those inside would not be tested if the vehicle itself has radiation levels below the standard.

If the radiation is above standard, one person, a “representative” of everyone in the car, would be checked and, if approved, the car would be allowed to continue on its way under the assumption that the others had also been exposed to levels below standard. This policy stands even if those levels might be more dangerous to children than adults.

Finally, there is the question of whether bus drivers would cooperate by going in and out of radioactive zones to help those who lack quick access to a car, especially senior citizens in need of assistance.

None of the concerns about the evacuation plans is new, and most have been pointed out by safety experts, medical professionals and anti-nuclear groups.

But with the NRA having approved restarts for three Kansai-area reactors that are over 40 years old, Kansai leaders are responding more cautiously to efforts to restart Mihama No. 3 in particular.

“It is absolutely crucial that local understanding for Mihama’s restart be obtained,” said pro-nuclear Fukui Gov. Issei Nishikawa in July, after a local newspaper survey showed that only about 37 percent of Fukui residents agree with the decision to restart old reactors.

Shiga Gov. Taizo Mikazuki, who is generally against nuclear power, was even more critical of the NRA’s decision to restart Mihama.

“There are major doubts about the law that regulates the use of nuclear reactors more than 40 years old. The central government and Kepconeed to explain safety countermeasures to residents who are uneasy. People are extremely uneasy about continuing to run old reactors,” the governor said earlier this month.

Power to the people: Swiss vote on exit from nuclear energy via The Daily Progress

GENEVA (AP) — Like other countries after the 2011 Fukushima disaster, Switzerland pledged to abandon nuclear power in coming years. But anti-nuclear advocacy groups say the Swiss government’s timetable isn’t fast enough, and have pushed for a referendum this weekend that would hasten the planned exit.

Swiss voters cast ballots on Sunday on an initiative championed by environmentalists and nuclear foes that would, if passed, shutter by 2029 the last of Switzerland’s five nuclear power plants that now generate 40 percent of the country’s electricity.

Polls suggest a tight race on an issue that could put Switzerland on a similar track to one in neighboring Germany. The Germans have been aggressively ramping up transition to renewables like solar energy in time to be done with nuclear energy by 2022, a deadline also set after a tsunami ravaged Japan’s Fukushima nuclear power facility five years ago.

 As part of an energy plan that runs through 2050, the Swiss government has already agreed not to replace its existing nuclear plants, which can operate as long as they’re deemed safe. The plants are to be closed progressively as their life spans expire, and the government says it needs time to switch to other sources such as wind, solar and biomass energy.

Switzerland regularly holds referendums as part of its particular form of direct democracy, which allows voters in the country of about 8.2 million to set policy on major issues — at times causing hassles for officials to carry out the public’s will.

465 suspected of working illegally at Fukushima nuke plant in 2015 via The Mainichi

[…]

Under a “disguised contract,” people are given work without official employment or are made to work under the instruction of parties other than those who place the original orders, obscuring the party responsible for their safety. The revelation comes after the Mainichi Shimbun reported that seven foreign nationals worked at the plant in 2014 under suspected illegal contracts. TEPCO had subsequently concluded that it had identified no problems over the issue based on its questionnaires.

The utility recognized that 118 of the 465 workers — whose employers TEPCO says it could identify and whom it checked with by way of the original contractors — were “all in appropriate employment statuses.”

In response to the TEPCO announcement, however, a former Japanese worker at the plant testified to the Mainichi that he “couldn’t write about the truth” in those surveys. Furthermore, at least one subcontractor related to work at the plant has admitted to the existence of disguised contract work.

[…]

A former male Japanese worker for a second-tier subcontractor that undertook work to build storage tanks for radiation contaminated water at the plant between 2014 and 2015 revealed to the Mainichi that when he responded to a TEPCO survey, he enclosed his answer sheet in an envelope and handed it over to a first-tier subcontractor without sealing it. The answer sheets submitted by workers were ultimately collected by the original contractor before being submitted to TEPCO.

“Although the surveys were anonymous, they could tell who wrote the answers by the handwriting. I couldn’t write about working under harsh conditions, in which many people collapsed due to heatstroke. The way the surveys are conducted now wouldn’t lead to uncovering the realities at the job sites,” he said.

The president of a construction company in Fukushima Prefecture that undertakes decommissioning work at the Fukushima No. 1 plant told the Mainichi in February that the company was making workers dispatched by another firm work at the plant by disguising them as its own regular employees. “I’m aware it constitutes disguised contract work, which is illegal. But it’s a common practice.”

Meanwhile, TEPCO’s public relations section, when asked whether its questionnaires can uncover the realities of work conditions for those engaged in decommissioning work at the plant, said, “We see no problems with them.”

South Africa’s proposed nuclear power plant unsafe – study via The Straits Times

 

JOHANNESBURG (REUTERS) – South African power provider Eskom has proposed building a nuclear power station on a site that may be at risk of surge storms and tsunamis, a geological report suggests, but the state-owned utility disputes the findings.

South Africa has the continent’s only nuclear power station and plans to expand nuclear power generation to meet growing electricity demand in Africa’s most industrisalised country.

The report by Maarten de Wit, a professor at the Nelson Mandela Metropolitan University and director of the Africa Earth Observatory Network, a research institute, says canyons in the bedrock would need to be secured.

 “If you are going to build anything on that, it’s pretty prone to storms, sea level rises and tsunamis,” De Wit told Reuters on Friday (Nov 25).

The site at Thyspunt, near Port Elizabeth in the Nelson Mandela Bay municipality, is on the Indian Ocean coastline.

 
 

The report also showed seismic activity along dormant fault lines near the site that could trigger submarine landslides.

Any such activity “is likely to generate a large submarine slump, and a possible significant local tsunami that would affect the coastal region, including Thyspunt,” the report said, warning that a plant at Thyspunt could be at risk of devastation similar to that in Fukushima in Japan in 2011.

27日の国民投票、スイスの原発は「古くなりすぎて危険」なのか? via SWI

緑の党など、国民投票にかけられるイニシアチブ「脱原発」の支持者は、スイスの原発の多くが世界で最も古い施設に属し、その老朽化が大事故のリスクを格段に高める、と主張する。そうした事故は、スイスのように人口密度の高い国では破滅的な被害をもたらすという。

スイスの有権者たちは、本当に原発の稼働年数だけを根拠に大事故を恐れているのだろうか?以下、さまざまな研究がそうではないことを示し、大事故のリスクにはその他の多くの要因が作用すると言っている。

深刻な事故はまれか?

世界原子力協会(WNA)は、商業用原発は「きわめて安全」で、「原発施設の事故が起きるリスクは低く、また低下している」と主張する。

同協会はウェブサイトで「商業用原発は原子炉年(1基×年数)換算で累積1兆6千年間、32カ国で稼働しているが、うち原子力施設で大事故が起きたのは3件」と公表している。

経済協力開発機構(OECD)の原子力機関(NEA)が出した2010年の調査も同様に、全電力網において実際に起こった事故のデータを分析し、「原子力発電は火力発電に比べて非常にリスクが低い」と結論づけた。最も多くの死者を出しているのは石炭部門。世界原子力協会は、大量の資源の発掘や発電所への運搬に伴う危険が一因とする。

しかし、連邦工科大学チューリヒ校と英サセックス大による最近の研究は、200件以上の事故を調べ、リスクが過小評価されていると示した。

研究者はメルトダウン(炉心溶融)が「どちらかと言えば」10~20年に一度起こると確信。原子力産業の示すデータは「亀裂が生じており極めて不完全」と断じ、原子力事故・故障のレベルを評価する国際原子力事象評価尺度はリスクを正しく理解するために改善されるべきだ、と話す。

ただ、事故を完璧かつ正しく描写できるのかどうかは不明だ。英科学誌ネイチャーによると、原子力の専門家は「客観的に『危険性』をランクづけるのはほぼ不可能。なぜなら原発施設はそれぞれ独自のリスクプロファイルを持っているし、ある種のリスクは単に人知を超えている」と話す。

専門家が一致するのは、色々な要素が考慮されなければならない、ということだ。経過年数はそのうちの一つに過ぎない。ネイチャー誌は、実は「必ずしも古い原子炉が新しいものより危険とは限らない」と明言する。

同誌は、三つの重大事故のうち2件は比較的新しい原子炉で発生したと考察する。米国のスリーマイル島事故は1978年当時、稼働3カ月でメルトダウンに陥り、チェルノブイリで災害が発生した86年時は、稼動からわずか2年後だった。2011年、福島の古い原発3基においては、津波が非常用電源と冷却装置を遮断したことで原子力事故に至っており、老朽化は直接の事故原因ではなかった。

(略)

検証と改良

世界原子力協会は、安全性の確保には検査官が中心的な役割を果たす、とする。国際原子力機関(IAEA)の原子力安全条約によると、経年により劣化や故障しやすくなる傾向はあるため、古い設備は定期検査と同時に大幅な改良が加えられなければならないという。地域レベルでは、スイスやEU諸国は、自国の原子力施設の稼働年数に関する報告書を提出し、17年に相互評価を行う方針だ。

スイス国内では、連邦核安全監督局(ENSI)が原発5基の寿命が続く限り、その運営を監督している。アールガウ州のベツナウ原発は、圧力容器の壁に生じた小さなひび割れがふさがれておらず、現在は閉鎖されている(1984年稼働開始のライプシュタット原発も安全上の理由で閉鎖されている)。万が一老朽化問題が深刻になれば、施設を廃炉にしなければならないという規定になっている。

40年から60年、そして80年へ

世界中の原子炉が老朽化しているという事実は、より多くの知識の共有やその安全性の研究に駆り立てている。

Radiation expert, 46, who investigated the ‘assassination’ of KGB spy Alexander Litvinenko ‘killed himself by stabbing his arms and chest repeatedly five months after a trip to Russia’ via DailyMail

A radiation expert who investigated the ‘assassination’ of Alexander Litvinenko was found dead five months after a trip to Russia, an inquest heard.

Father-of-two Matthew Puncher, 46, bled to death at his home from multiple stab wounds inflicted by two knives.

A pathologist said he could not ‘ exclude’ the possibility that someone else was involved in the death – but concluded the injuries were self-inflicted.

It led a coroner to record that Dr Puncher – who discovered the amount of toxic polonium inside ex-KGB agent Litvinenko after he drank poisoned tea in London in 2006 – committed suicide.

[…]

He was an expert in radiation protection dosimetry and worked for Public Health England at the UK’s Atomic Energy Research Establishment at Harwell, Oxfordshire.

He had been given sole responsibility over a contract with the US Federal Government for a programme measuring polonium levels inside people who previously worked on the USSR’s nuclear weapons. 

Head of department at Harwell, George Etherington, described Dr Puncher’s concerns that his ‘miscalculation’ of the effects of the radiation on the workers would land him prison as ‘irrational’.

The inquest also heard that redundancies and restructuring at Public Health England’s premises in Harwell, near Didcot, had resulted in Mr Puncher receiving a much greater workload.
