川内原発、初の住民説明会始まる 再稼働めぐり via 日本経済新聞

九州電力川内原子力発電所(鹿児島県薩摩川内市)の再稼働に向け、初めての住民説明会が9日午後7時、同市内で始まった。原子力規制庁の職員が安全 審査の内容を説明する。説明会は15日までに県内計5カ所で予定され、県と同市は原発の安全性について住民の理解を得たうえで再稼働同意の手続きに入りた い考えだ。

原子力規制委員会が9月10日、川内原発1、2号機に安全審査合格を出し、同原発は再稼働第1号となる見通し。10月9日夜は会場の川内文化ホール(同市)に定員いっぱいの住民が詰めかけた。

地元同意は原子力規制委員会の認可手続きと並び、再稼働の条件となっている。立地自治体である鹿児島県と薩摩川内市は同意手続きに入るには、国が関与する形で安全性などを住民に説明し理解を得ることを前提としていた。

県内での住民説明会はこの後、日置、いちき串木野、阿久根の各市とさつま町の4カ所で開かれる。その結果を踏まえ、薩摩川内市議会と岩切秀雄市長、鹿児島 県議会と伊藤祐一郎知事が再稼働への態度を表明する手続きに入る見通し。同市長、県知事とも従来から早期再稼働を求めており、最終的に同意する可能性が高 い。

(略)

伊藤知事は同意の必要がある自治体を「県と薩摩川内市で十分」との主張を繰り返している。県と周辺自治体の溝は今のところ埋まらず、今冬以降とみられる再稼働に影響する可能性もある。

Go Figure: What bananas tell us about radiation via BBC

There’s been concern about radiation after damage to Japan’s Fukushima nuclear plant in March and now a hot spot has been detected in Tokyo. But how do we think of radiation in ordinary terms, asks Michael Blastland in his regular column.

Freaky, isn’t it, radiation? Invisible, baffling, harmful (bombs) and helpful (X-rays) or both (nuclear power). And we go nuts if someone wants to put a load in our backyard even though it’s everywhere.

How much easier if our exposure to the hazards of radiation could all be reduced to bananas. Actually, it can, sort of. Welcome to the Banana Equivalent Dose or BED.

[…]

But I reckon the BED is useful for several reasons. First, it reminds us that radiation is commonplace. You can’t get much more ordinary than a banana.

Second, we know eating one banana won’t kill us. Not even nearly. Not without extreme violence. This affirms an age-old point about toxicity – that danger is in the dose. In other words most things, radiation included, are only dangerous in sufficient quantities. The distinction between toxic and safe is not really a distinction of kind, but of quantity. That goes for just about everything from water and vitamins to arsenic.

Third, think about eating 20 million bananas, equal to a dose causing severe, sometimes fatal, radiation poisoning. You’d probably die from something other than the radiation well before you were anywhere near 20 million. Do not attempt this at home. Even over an 80-year lifetime it’s nearly 700 a day. Brings to mind Cool Hand Luke’s 50 eggs in one hour.

So by putting all radiation exposure on one scale, the banana scale, we see clearly how huge a scale it is. At low doses the bananas come in bunches, then rise through the thousands to the millions, corresponding to micro-sieverts, milli-sieverts and sieverts, the SI unit.

[…]

This article, while somewhat informative for the uninitiated, is rather misleading from a scientific perspective. The “banana equivalent dose” is frowned upon by radiation protection specialists like me. While it’s true that bananas contain potassium and, by extension, radioactive potassium-40, humans don’t simply absorb all of the radiation that the potassium-40 emits. The body keeps a more or less constant inventory of all the potassium it needs. When you ingest potassium, some of it is retained and the extra potassium is excreted. As a result, some of the “banana equivalent dose” is not retained in the body but passes right through. Because this amount also differs from person to person, it’s not a good method of comparison. Comparing it to a known quantity, such as a chest or dental x-ray, would be more scientifically accurate while allowing you to make the same point to your readers.

John Harvey PhD, Atlanta, Georgia, United States

[…]

Bananas are radioactive because they contain some Potassium-40. So do many things. But the reason this idea is absurd is that different radioisotopes exist which have different biological affinities. Potassium is uniformly distributed in the body and so can be compared with external radiation. Not so substances like Strontium-90 and Uranium 238 or Plutonium 239 which have high affinity to DNAS and so can deliver their energy where it is effective is causing mutation. Almost all of the potassium 40 radiation is wasted.

中嶌哲演さん 応援メッセージ via 福井県民署名サイト

この署名活動は一部の反対派だけのものではありません。

キックオフ集会の中でもアピールしたのですが、今回の福井県民署名は一部の反対する人々が押し進めればいい署名活動なんだということは決してありま せん。なぜなら、福島の原発事故の影響は広域にわたっており、農民、漁民、商店街の人々、町役場に努める人、保育園や学校の教師、病院、福祉施設の看護 士、介護士、障がい者、神社や寺院まで、あらゆる人々に及び、12万人以上(復興庁:難者数の推移 [平成26年10月2日]より)もの福島の人達が自分の故郷を捨てなければならなくなってるからです。

福井地裁は原発から半径250km圏内の住民の請求に応えて、原発の運転をしてはならないと判決を下しました。

私は、原子力ムラの人達だけに全ての責任があるとは思っていないんですよ。もちろん根本的には彼らに責任がありますが、いわゆる大量生産、大量消 費、大量廃棄の現代文明や、必要神話、安全神話によってマインドコントロールされてきた国民全体は、原発の恩恵を享受してきたわけです。原子力ムラを糾弾 したり批判するだけでは済まないことを一般国民一人ひとりが自覚する必要があると思います。

若狭の原発はなにも福井県だけの問題ではありません。若狭の原発の電気は長年関西圏に送られてきました。
関西圏のみなさまは、今までは原発で作られる電気の恩恵だけを受けて来たわけですが、若狭の原発で大事故が起きれば関西圏にも被害が及んでいくことが福島 の事故でまざまざと分かったわけですから、自分自身の安全を守る為にも行動を起こすことは必要だと思いますし、都市部の繁栄のためにいわば負の部分として 危険な原発を田舎に押し付けてきたわけですから、これからは現地若狭が原発から脱却していく道に連帯した応援をしていくことを考えていただけたらと思いま す。

若狭の人達は原発に依存しなくてはならないという考えを持たされ、はっきりと再稼働に反対する気持ちや考えを持てない状況にまで追い込まれていると いうことをよくご理解いただいた上で、若狭が原発に依存しないで、どうやったら美しい自然を活かした地域づくりができるのか、みなさんにもアイデアを出し て欲しいですし、その取り組みの中で、みなさんに出来る応援の仕方も考えていっていただきたいと思うわけです。

(略)

今回の署名活動が、原発の問題の過去、現在を知った上で、これから未来に向けてどうしたら良いのか、考えてもらう機会として広がって行くことを願っ ています。もちろん署名の数も大事ですが、一人ひとりが自分の問題として考え、みんなで話し合いながら、若狭の原発を本当に動かして良いのか判断し、その 形としての署名を西川知事に提出することに意味があるんだと考えています。

South Korean Town to Put Nuclear Plan to Vote via ABC News

Fighting plans to build a nuclear power plant, a South Korean fishing village is holding a referendum Thursday, even though the government has warned the vote is illegal.

A site in Samcheok, 195 kilometers (120 miles) east of Seoul, was picked by the energy ministry after a previous city government applied in 2010 for a nuclear power facility. But attitudes have shifted since Japan’s 2011 nuclear disaster at the Fukushima.

Now, the city council has set up a volunteer committee to conduct a vote on whether Samcheok still wants the plant after election authorities refused to administer the referendum. Supporters of the nuclear plant say they will boycott.

South Koreans’ pride in the country’s nuclear power industry has eroded since scandals erupted last year over revelations hundreds of faulty components may have been used in reactors. That forced nearly half the country’s 23 reactors to shut down.

Critics of nuclear reactors also became more vocal about safety after an April ferry sinking killed hundreds of people and fueled complaints the country emphasized profit over safety.

In Samcheok, about 39,000 out of 61,000 registered local voters signed up to take part, and about 70 percent were expected to vote, according to Chung Yeon-man, a committee member.

Nuclear energy supplied a quarter of South Korea’s power last year, and the government wants to boost that to 29 percent by 2035. That would require adding 7 gigawatts of generating capacity, or the equivalent of five 1.4-gigawatt reactors.

The country also is starting to export nuclear technology. It won a $20 billion contract from the United Arab Emirates in 2009.

Tsunami, not Quake, Seen as Main Cause of Fukushima Accident via Wall Street Journal

Japan’s nuclear regulator said Wednesday that the tsunami following the March 11, 2011, earthquake–not the quake itself–was the main cause of the accident at the Fukushima Daiichi nuclear power plant.

The conclusion matters because of the implications for other nuclear-power plants. Virtually all of Japan is prone to earthquakes, but some places are relatively protected from tsunamis. Currently all of the nation’s 48 reactors are offline, and the government is weighing whether to restart some next year.

In the March 2011 nuclear accident, three reactors melted down after the plant lost main and backup power, paralyzing cooling systems.

The Nuclear Regulation Authority studied why the No.1 reactor lost backup power and concluded on Wednesday in a report that the tsunami was the main cause, based on data about temperature, pressure and other parameters. Those data were stable immediately after the earthquake hit at 2:46 p.m., suggesting the plant didn’t suffer critical damage until the arrival of the tsunami some 45 minutes later.

A previous investigation by Japan’s parliament had left more room for the possibility that the earthquake itself did significant damage.

Nuclear workers kept in dark on Fukushima hazard pay via Reuters

(Reuters) – Almost a year after Japan pledged to double hazard pay at the stricken Fukushima nuclear plant, workers are still in the dark about how much extra they are getting paid, if anything, for cleaning up the worst nuclear disaster since Chernobyl.

Under pressure to improve working conditions at Fukushima after a series of radioactive water leaks last year, Tokyo Electric Power Co President Naomi Hirose promised in November to double the hazard pay the utility allocates to its subcontractors for plant workers. That would have increased the amount each worker at the nuclear facility is supposed to earn to about $180 a day in hazard pay.

Only one of the more than three dozen workers interviewed by Reuters from July through September said he received the full hazard pay increase promised by Tepco. Some workers said they got nothing. In cases where payslips detailed a hazard allowance, the amounts ranged from $36 to about $90 a day – at best half of what Hirose promised.

In some instances, workers said they were told they would be paid a hazard bonus based on how much radiation they absorb – an incentive to take additional risks at a dangerous work site.

One worker interviewed by Reuters said he was told he would get an additional $45 per day every time he was in so-called “hot zones” near Reactors No. 1 and No. 2. Another worker was told he would receive an hourly rate that worked out to $4,500 extra in hazard pay for being exposed to the radiation limit for Japan’s nuclear workers over a five-year period. And a third worker said he was told the payout for that same exposure would be $36,000.

[…]

Tepco still relies on some 800 mostly small contractors to provide workers for the cleanup after the tsunami that swamped the plant on March 11, 2011 sparked meltdowns at three reactors. Subcontractors provide almost all of the 6,000 workers now employed at the plant. Tokyo Electric employs only about 250 on its own payroll at the facility.

The workforce at Fukushima has almost doubled over the past year, mostly as part of an effort to protect groundwater from being contaminated and to store water that comes in contact with melted fuel in the reactor buildings.

Some of the workers who arrived recently at the plant have been building bunkers to store highly radioactive sludge, which is a by-product of the process whereby contaminated water is treated. Others are installing equipment to freeze a ring of earth around four reactors at Fukushima to keep water from reaching the melted cores, an unprecedented effort directed by Kajima Corp and expected to cost nearly $300 million.

Kazumitsu Nawata, a professor in the University of Tokyo’s department of technology who has researched conditions inside Fukushima, said that if workers do not receive pay that is commensurate with the risks they are taking, they will ultimately look elsewhere for employment. If more experienced workers leave for safer jobs in Tokyo where construction projects are accelerating ahead of the 2020 Olympic Games, it will also increase the likelihood of accidents at the plant, Nawata said in an interview.

“Until now, we have relied heavily on the goodwill of workers. But it’s already been three years since the accident. This is no longer sustainable,” he said.

 

[…]

Sakurada moved to Fukushima in May 2012 to be closer to his fiancée in Iwaki. He took a job with a local company because he was promised a place to stay.

TOP, a local firm that supplies workers for construction, only told Sakurada he would be working in the nuclear plant two days before he started. When Sakurada asked for a pay rise to compensate for the increased danger, he said a TOP manager told him it would be unfair to others to pay him more.

By early 2014, Sakurada said he’d seen a 56-year-old worker fired for reaching his radiation limit. He had also watched another middle-aged worker – a man he did not know – die in front of him of an apparent heart attack. None of the other workers knew how to revive him with a defibrillator kept in the break room, he said.

Sakurada quit in May. Unlike the other plaintiffs in the lawsuit, he agreed to be interviewed and identified by name for this report.

TOP’s manager did not respond to repeated calls to the company headquarters or faxed questions about Sakurada’s claims.

“The whole structure at Fukushima, everything from working hours to radiation levels, needs to be made clear. Like hitting a reset button,” said Sakurada.

SPEEDI、原発事故の避難判断に使わず 規制委方針 via 朝日新聞

 原発などで重大事故が起きた際に放射性物質の広がりを予測する「SPEEDI(スピーディ)」(緊急時迅速放射能影響予測ネットワークシステム)について、原子力規制委員会は8日、住民避難などの判断に使わない運用方針を決めた。すでに、放射線量の実測値をもとに判断する態勢に転換しているが、SPEEDIの使い方があいまいで、避難計画を作る自治体から明確化を求められたためだ。

東京電力福島第一原発事故では、予測のもとになる原子炉などの情報が得られないなか、初期の住民避難に活用されず問題になった。規制委は昨年2月に原子力災害対策指針を改め、重大事故が起きた段階で5キロ圏内は即避難、30キロ圏は屋内退避したうえで、周辺のモニタリングポストによる放射線量の実測値をもとに避難などの判断をすることにした。

事故前、避難の指標とすると位置づけられていたSPEEDIは、「参考情報」に格下げされた。だが、使い方は具体的に示されておらず、予測結果を避難の判断に使えると受け止める自治体もあった。

この日に決めた運用方針で、避難の判断以外の使い方を示すことを明記。放射性物質の放出が収まった後、放射性ヨウ素などの被曝(ひばく)線量の事後評価などの例を示す。対策指針に基づくマニュアルは、重大事故発生時にSPEEDIで計算を始め、結果を公表するとしているが、混乱を招くおそれがあることから、計算自体しないよう修正する。
