Britain to ship record amount of nuclear waste to U.S.: UK government source via Reuters

Britain will ship 700 kilograms of nuclear waste to the United States under a deal to be announced by Prime Minister David Cameron at a nuclear security summit in Washington on Thursday, a British government source said.

In return for the shipment, the largest ever movement of highly enriched uranium, the United States will send Europe a different type of nuclear waste that can be used to produce medical isotopes for the treatment of some cancers.

“The prime minister will be announcing a landmark deal that we have agreed with the US and with (European Atomic Energy Community) Euratom,” the British government source said, on condition of anonymity.

“It is a win-win. We get rid of waste and we get back something that will help us to fight cancer.”

Cultural park could become nuclear plant via Sedona Red Rock News

Sedona may soon be entering the nuclear age.

The state of Arizona recently approached the city of Sedona and the property owners of the Sedona Cultural Park on the construction of small nuclear power plant at the site.

The station would not be anywhere near as large as the Palo Verde Nuclear Generating Station in Tonopah, which generates 3.3 gigawatts of power.

By net generation, Palo Verde is the largest nuclear power station in the country, serving roughly 4 million people in Arizona and Southern California, but the increasing population in the Southwest, means the power plant will reach capacity sooner rather than later, according to Palo Verde Nuclear Expansion Program Chief Spokeswoman Cher Nobel-Pripyat.

[…]

In January, the property was sold to a private firm, Burns Holdings LLC, which has owned and operated a small nuclear power plant in Springfield, Ore., since December 1989. The plant would be jointly owned by Arizona Public Service, Burns Holdings, Salt River Project and Southern California Edison. Areva would own a minor portion for the first 10 years, before divvying up its share proportionally among the other stakeholders.

“We feel the Sedona site is excellent for our plans,” Burns Holdings CEO and owner C. Montgomery Burns said. “Excellent.”

Construction would likely not begin until summer 2017, after the conclusion of a National Environmental Policy Act assessment, which is set to be conducted this summer.

500人の証言が明かす過酷事故の真実 Nスペ「メルトダウン 危機の88時間」 – 田部康喜 (東日本国際大学客員教授)via BLOGOS

(抜粋)

NHKスペシャル「メルトダウン 危機の88時間」(3月13日)は、福島第1原子力発電所の事故について、その責任を追及することを急がず、現 場の事実を積み上げてみせた。亡き吉田昌郎所長が国会事故調査委員会の聞き取りに答えた、未公開の証言に加えて、関係者約500人の証言が裏付けになって いる。当時の現場の状況を再現するドラマが、事実をより理解しやすくさせている。

88時間目に起きたこととは

大震災と巨大津波から88時間目とは、第1号機と第3号機がメルトダウンを起こし、緊急冷却装置が稼働してかろうじてメルトダウンを免れていた第2号機が原子炉格納容器の爆発の危機に陥った瞬間だった。

格納容器が爆発すれば、大量の放射能汚染物質が周囲に拡散するばかりか、第1原子力発電所に立ち入りができなくなり、原発事故の収拾は困難になる。さらに、放射能汚染物質は隣の福島第2原子力発電所にも流れ込み、この発電所の地震と津波による被害対策もできなくなる。

さらには、東電関係者の証言として、「東日本に人が住めなくなる」と思った瞬間であった。「日本がダメになる。そのことを死ぬまで忘れない」と別の証言者は語る。

(略)

同日午後9時すぎ、第2号機がメルトダウンする。ベントもできず、格納容器の圧力は高まる。

吉田所長は「討ち死にになる。第2(原子力発電所)のほうも作業ができなくなる。あとは神に祈るだけだ」と考える。

東京電力の本店が考えていたのは、「ドライウェル・ベント」だった。放射能汚染物質を水に通さずにそのまま外に放出する、禁じ手ともいえる方法である。

本店 「ドライウェル・ベントをやれ! 責任はこっちでとる」

吉田所長 「やってますから。ディスターブ(邪魔)しないでください!」

現場からは「ドライウェル・ベントできません!」という声が。作業区域内に人が入れば、15分以内に死亡する放射線量に達していたのだった。

(略)

結果として、第2号機の原子炉格納容器は爆発を免れた。建物の揺れは第4号機の水素爆発によると推測されている。同機は運転休止中だったが、第3号機から漏れた水素が建屋内に充満したらしい。

第2号機の格納容器は上部の継ぎ目付近がひび割れたようになって、それによって内部の気体が外部に排出されて圧力が下がったと考えられている。ただし、その部分を直接確認するには至っていない。第2号機はその後1週間にわたって大量の放射能汚染物質を放出した。

吉田所長は「10人くらい昔から知っているやつ、こいつらだったら死んでくれるかなと思った。すさまじい状態だった。天の助けがないと、もっとひどいことになった」と証言している。

Japan and South Korea hit back at Trump’s nuclear comments via CNN

Seoul (CNN)Confused, shocked, bewildered. Just a few of the words used in recent days to describe Japan and South Korea’s reaction to some of Donald Trump’s latest comments about the region.

The front-runner for the Republican presidential nomination stunned two of America’s strongest allies with the suggestion that the U.S. military would be withdrawn from their shores, with nuclear weapons replacing them.
There are currently 54,000 U.S. troops stationed in Japan and 28,500 in South Korea.
“Japan is better if it protects itself against this maniac of North Korea,” Trump told CNN’s Anderson Cooper Tuesday. “We are better off frankly if South Korea is going to start protecting itself … they have to protect themselves or they have to pay us.”
[…]
Japan remains the only country to have had nuclear weapons used against it and has had a non-nuclear policy and pacifist constitution since the end of World War II.
Foreign Minister Fumio Kishida added, “It is impossible that Japan will arm itself with nuclear weapons.”
[…]
South Korea has a small minority who think Trump may have a point and welcome the idea of nuclear weapons.
Academic Cheong Seong-Chang from the non-profit think-tank the Sejong Institute said, “If we have nuclear weapons, we’ll be in a much better position to deal with North Korea.”
But his feeling is not mainstream.

Ryuichi Sakamoto offers his thoughts on politics, Japan and how his music will change ‘post-cancer’ via Japan Times

“The Professor” is back in town. Last weekend, Ryuichi Sakamoto took the stage at Tokyo Opera City for the debut concert of the Tohoku Youth Orchestra, a 105-strong ensemble of young musicians from Iwate, Miyagi and Fukushima prefectures, which counts him as its musical director.

Though he isn’t inclined to make a fuss about these things, the occasion also had personal significance for the 64-year-old composer and musician, a longtime New York resident. It was the first concert Sakamoto had played since undergoing treatment for throat cancer in 2014, canceling all engagements in what must be one of the music industry’s busiest work schedules. As he later remarked, it was the first extensive time off he’d had for 40 years.

[…]

Does he worry a lot about Japan’s future?

“I do, I do. One of the unfortunate things that’s happened in the three or so years since Abe came to power is that Japanese people are going on about how brilliant Japan is: ‘This is great! This place is amazing!’ There are too many TV programs and campaigns like that, and I’m getting a little sick of it. It’s fine if people from outside the country praise you like that, but to say it yourself — things like ‘Cool Japan’ — I don’t think that’s ‘cool.’ ”

Being one of the country’s most internationally renowned cultural icons, Sakamoto may seem like an obvious ambassador for the government’s campaign to promote Japanese soft power overseas. So it’s surprising when he says that he hasn’t even been approached by the apparatchiks behind Cool Japan.

Maybe it’s because the campaign originates within the halls of the Ministry of Economy, Trade and Industry — the main cheerleader for Japan’s nuclear power industry.

“I hate them, and I think the feeling’s mutual,” he says.

The organizers of the 2020 Tokyo Olympics can also strike Sakamoto’s name from their invitation list. Although he composed and conducted the music for the opening ceremony at the Barcelona Games in 1992, he says that he wouldn’t be interested in taking part when the event returns to Japan.

Asked why, he reels off a list of the problems that continue to afflict the Tohoku region: the tens of thousands of people still living in temporary housing, the nuclear disaster evacuees unable to return home, the ongoing problems with cleanup efforts at the Fukushima No. 1 nuclear plant.

“It’s not ‘under control’ at all, is it?” he says, echoing the words used by Abe in his speech to the International Olympic Committee in 2013. “They should be making that their first priority.”

For Sakamoto, the way to end Japan’s current malaise is through encouraging fresh thinking — though he concedes that this is difficult in “a society where it’s hard to say things that others don’t agree with.”

“You won’t get original thinking in an environment like that. The ideas won’t come, and the talented people will just end up going overseas,” he says as we wrap things up.

“I’ve been saying this for a long time,” he concludes, “but if you take Sony, which is a company that really represents Japan, and compare it to Akira Kurosawa — just one person — Kurosawa is probably worth more worldwide. A lot of people don’t seem to get that.”

Ice wall at Fukushima plant switched on, but will it work? via AP

Q. WHAT IS AN ICE WALL?

A. Engineers installed 1,550 underground refrigeration pipes designed to create a 1.5-kilometer (0.9-mile) barrier of frozen soil around four damaged reactor buildings and their turbines to control groundwater flowing into the area and prevent radioactive water from seeping out. The pipes are 30 meters (100 feet) deep, the equivalent of a 10-story building. Engineers say coolant in the pipes will freeze the surrounding soil to minus 30 degrees Celsius (minus 22 Fahrenheit), creating the wall over several months.

Q. WHY IS AN ICE WALL NEEDED?

A. The cores of three of the damaged reactors melted during the accident and must be cooled constantly with water to keep them from overheating again. The cooling water becomes radioactive and leaks out through damaged areas into the building basements, where it mixes with groundwater, increasing the volume of contaminated water. Nearly 800,000 tons of radioactive water have been pumped out, treated and stored in 1,000 tanks that now occupy virtually every corner of the Fukushima plant, interfering with its decontamination and decommissioning and adding to the risk of further leaks of water into the nearby ocean.

Q. ARE THERE RISKS?

A. Construction officials say the coolant is environmentally safe. There were doubts that the huge refrigeration system could effectively freeze the soil while groundwater continues to flow in the area. The operator, Tokyo Electric Power Co., says results from a test of part of the wall last summer were mixed but suggest the system has sufficient capability. Experts are also concerned that an ice wall cannot be adjusted quickly in an emergency situation, such as a sudden increase in the flow of contaminated water, because it takes several weeks to freeze or melt. Electrical costs for running the refrigeration system could be steep. TEPCO says the wall, once formed, can remain frozen for up to two months in the event of a power failure.[…]

検証委、川内東部の避難解除「妥当」 村長「時期こだわらない」via 福島民有

[…]答申によると、除染の効果で、空間放射線量が大部分で毎時0.8マイクロシーベルトを超える世帯はないと報告。比較的線量が高い地点も一部に散在し、局地的な除染や遮蔽(しゃへい)のための覆土などの適切な対応が必要と指摘した。

 放射線による健康影響については、避難指示解除を判断するための準備宿泊で1人の個人線量計を使って推計した結果、追加被ばく線量は年間1.6ミリシーベルト程度で「低いレベル」と評価した。ただ、対象が1人にとどまっており、今後も被ばく線量を基にきめ細かな相談対応を充実すべきだとした。

東京電力福島第1原発事故 子ども甲状腺検診、那須塩原で5月8日 /栃木via 毎日新聞

東京電力福島第1原発事故に伴う放射線の健康影響問題に取り組んでいる市民団体「311『つながる、つたえる、そして未来へ』集い実行委員会」(田代真人実行委員長)が5月8日、那須塩原市上厚崎の厚崎公民館で「子ども甲状腺検診」を開く。
[…]
実行委は2015年3月に那須塩原市で、同6月に那須町で検診を実施しており、今回が3回目。

 原発事故の健康影響を調べる福島県の調査で見つかった子どもの甲状腺がんや疑い例は、全国の発症者の割合から推計される患者数に比べて多い。多くの専門家は多人数を対象に精密な検査をしたことによる「過剰診断」が主な原因とする。一方、被ばくが主因と考える専門家もいる。

 実行委が今月27日に開いたシンポジウムでは、今後の議論の参考にしてほしいと、双方の立場の専門家を招き意見を聞いた。田代さんは「放射線は福島と栃木の県境で止まったわけではない。被害があるかどうか実態を調べるため、栃木でも継続して検診を実施すべきだ」と話している。
