浜岡で炉心損傷想定 中電が全社防災訓練
http://www.at-s.com/news/article/social/shizuoka/hamaoka/155564.html

中部電力は25日、浜岡原発(御前崎市佐倉)での重大事故を想定し同原発などで全社防災訓練を実施した。同市で震度7の巨大地震が発生し、運転中の4号機が炉心損傷に至る過酷な状況を想定。訓練者に、事前に想定内容を明かさない「ブラインド方式」で進めた。

中電によると、原子炉格納容器の破損につながる恐れがある炉心損傷を想定するのは従来の全社防災訓練で最も厳しい。
4号機の運転を訓練するシミュレーター室では、警報音が鳴り響く中、運転員が操作盤で原子炉の状況を監視した。異常で原子炉の水位が低下し始めると、非常用炉心冷却系のポンプを起動させ注水した。

緊急時対策所には災害対策本部が設置された。井原一郎浜岡原子力発電所長をトップとする幹部が、名古屋市の本店などとテレビ会議をつなぎ、格納容器の破損を防ぐための対策を講じた。

 中電によると、訓練は本店も含め計約2800人を対象に実施した。

炉心損傷など本来は有ってはならない事故を想定すれば、福一を思い出して住民の不安を招くことになるので電力会社としては避けたい訓練だな。

それを唯一やる中電は評価したいな。

但し、浜岡は自治体も住民も再稼働に同意していない数少ない原発だし、中電管轄は電力量も足りているので無理に再稼働して欲しくない。

知り合いの中電社員も万が一にも東電のようになりたくないので、多くの同僚社員が本音では再稼働に反対だそうですよ。

訓練だの安全対策だのをやっても
結局爆発すれば放射能拡散で
知らぬ存ぜぬが始まる訳なので
もはや厳しい審査だの基準だの
何をどう弁明しようと意味が無いのだよね。

事故前と事故後では国、電力会社の
姿勢は全く違う物になる。

普通大事故を起こせば企業は潰れ
責任追求される筈だが、原発事故は
御用学者、工作員を使い国民を
洗脳し反原発にぶつけ丸め込もうと
している。


原発事故が無ければ放射能漏れは
大事件だった筈だがもはや今では
拡散上等、寧ろ食べれば復興となっている。

50ミリ帰還政策が今目の前で進められている。
何が安全なのか危険なのかさえ
わからなくなっている。
もうめちゃくちゃだ。

2007年の中越沖地震で柏崎刈羽原発は1m以上の地盤沈下が敷地内の道路であり、地下に埋設されていたさまざまな配管が被害を受けました。このとき、柏崎刈羽原発は中越沖地震の震源域ではなく、数キロ離れていたのです。

東海地震が起こると、浜岡原発はほぼ確実に震源域内にあることになり、中越沖地震での柏崎刈羽原発とは比較にならないほど大きな影響を受けるはずです。

地盤沈下とそれに伴う地下埋設施設の被害、建築物の不同沈下とそれによる建物被害(つまり、地上の配管が壊れる被害など)が確実に発生するはずで、そういったことについて対策をたてないといけないのです。

>4号機の運転を訓練するシミュレーター室では、警報音が鳴り響く中、運転員が操作盤で原子炉の状況を監視した。異常で原子炉の水位が低下し始めると、非常用炉心冷却系のポンプを起動させ注水した。

なんていうことは初歩の初歩、こんなことをやってアッピールしているようでは、多分、上のこと、つまり、地盤沈下対策はやられていない。

ちなみに、中電は、東海地震で地盤が緩やかに隆起するとしている。しかし、311の大地震で福島第一原発や女川原発の敷地が地盤沈下したのとは全く様相が違います。311のときは、震源域は沖合150キロであり、福島や女川は陸側プレートに乗っていただけで、陸側プレートが大きく沈下したため、ほとんど不同沈下はなかった。しかし、東海地震では震源域に浜岡原発があるため、アスペリティの破壊の衝撃が直接伝わるし、また、地盤が最も激しく揺れ動く位置にある。浜岡原発敷地内で不同沈下が起こる可能性は非常に強い。

福島第一原発事故では、地震の15分後に、燃料棒の損傷が生じて、放射性物質が漏れ出したことが、CTBTOのモニタリングデータ解析から、判明している。

地震によって、圧力容器が破壊されたか、あるいは主蒸気配管が損傷して、冷却材が急速に失われたことを示唆している。

シミュレーションには、対応できる事態が想定されているだけであって、福島第一原発のような事態には対応できないことは明らかだ。

こんな訓練を何度繰り返しても、過酷事故は防ぐことができない。

今回の訓練は、遠くない将来の再稼働を見越して、そのアリバイ作りのために行われた。

福島原発事故の原因究明をなおざりにして、事故対策もおざなりのまま、再稼働に突っ走る、この国の愚かさ、狂気には、寒気がする。

ツイッターで、福島第一原発3号機爆発直後の写真があることを、教えられた。

ものすごい量の黒煙が、福島原発の頭上を覆っている写真で、これまで公開された、どの写真より、真実を語っているように思える。

この写真を見た後では、3号機は核爆発であることと、作業員の中には、被曝死が、かなり出ていることを確信した。

写真は、イランのプレス・テレビが、バスビー博士へのインタビュー記事に添えたものだ。

現在は、リンク切れになっている。

なお、バスビー博士は、旧ソ連のマヤク事故の例を挙げて、核燃料がメルトダウンした場合、核爆発が起きることを語っている。

>'Japan careless about radiation dangers' Thu Mar 24, 2011 9:4AM

Interview with Professor Chris Busby from the European committee on radiation, London

Fukushuma nuclear power plant explosion in Japan
Japanese authorities have played down the nuclear reactor leak and the significance of informing citizens of minimal danger, but in fact the opposite is the case.


Press TV interviews Professor Chris Busby from the European committee on radiation in London who has tried to warn the Japanese that the facts point to risk at the level of Chernobyl or even greater and that Tokyo is at risk.

Press TV: How serious is the situation regarding a radiation leak from the nuclear plant that is taking place in Japan?

Professor Busby: This situation is very similar to Chernobyl in the way in which at the beginning everyone said it was not a big problem, and then they said there was no much radiation; and then along the line we see them backing away from that position as it is getting more and more serious.

At the present time my feeling is that it is probably getting very close to that of Chernobyl. I don't believe a lot of the communiques coming out and there is enough factual information from these; however, for me to be able to estimate that a huge amount of radioactivity has already come out of that plant.

For example, on the IAEA website last night a bulletin said the concentration of contamination has spread 58 kilometers from the plant. That level is about twice as high as the level of the Chernobyl exclusion zone. The Chernobyl exclusion zone was only 30 kilometers. So we're talking about levels of that in comparison are greater already.

Press TV: The communiques you say you don't believe them - Why is there disinformation then coming out of the Japanese media and why is there not more information coming from the IAEA on this?

Professor Busby: I don't think the IAEA really knows what's going on. To some extent they have to listen to what they're being told by Japanese authorities. People are not able to tell what is actually happening inside the reactors because the radiation levels are so high you just can't approach the reactors without dying. That's the problem.

And all the instrumentation - the stuff you have in the control room that measures what's going on in the reactor of course is all destroyed. So there is no way to know what is going on.

They have been making desperate attempts to cool both the fuel rods and the reactors themselves just by tipping water on them, which means they can't get water into the reactors it seems.

These are concentrations the IAEA have been publishing. So it's not a question of not believing; it's a question of deducing what's happened on the basis of what facts are available. And the two bits of facts which are available are that the radiation levels are extremely high; quite a distance from the plant, and secondly, the contamination level on the ground is extremely high within at least 50 kilometers from the plant.

Press TV: You are saying that you think the situation is as major or almost as major as Chernobyl. At this point in time what do you think they can do? Is there anything they can do to stop this from deteriorating even further?

Professor Busby: I can't think of anything. It seems to me that the fuel has actually melted inside the reactor pressure vessels and so there is a pool of molten fuel in the bottom of at least three of those pressure vessels - so that's the first problem.

And it's not possible to cool that just by pouring water on it. You can cool reactor rods, which are separate, by circulating water through them, but you can't water down a great hot lump of metal. And the other problem I believe is the spent fuel on top of reactors 1, 2 and 3 have already been blown up into the air- so that's something they can't do anything about- littering the plant all around the area; it's probably in the sea; the sea is contaminated.

No one has ever seen this happen before and it's hard to know quite what they can do. I don't have any solutions except to pray.

Press TV: What has been taking place is black smoke coming out of reactor three and white smoke coming out elsewhere. What does it mean - the different color of the smoke?

Professor Busby: I can only guess. All we know is that there is white smoke and black smoke. What I can say for sure is that both the white and black smoke are intensely radioactive; there is no question about that. And my feeling is that some of this smoke consists of very hot radioactive particles - So, very small particles that reflect the light and will float away over the sea or whichever direction the wind is blowing.

In the European Committee on Radiation for about five days now we've been modeling the air flows, which took the first and third reactor explosions out to sea and then back over Tokyo. We can see that it goes out and around in a big circle over Tokyo and then it goes north over the country.

Before it turned around it had clipped Okinawa and that's why they thought that the power plant there was melting down because they got a sudden hit of radiation there.

So these radioactive materials such as Uranium and Tritium and Iodine of course and others are now contaminating the island of Honshu, which is a large distance from the plant and this will have significant effects on the health of the population there.

Press TV: Evacuation orders were carried out within 20 kilometers of the plant. If you were in a position of decision making inside Japan, would you have ordered the evacuation to cover a greater area?

Professor Busby: Yes and right from the beginning. In fact I did advise them - we put advice on various websites including the European Committee's website to take it more than 100 kilometers. Now I believe they should consider taking people out of Tokyo. I don't know where they're going to put them, this is problem- it's a nightmare.

Tokyo itself is certainly under risk from radioactivity not just from the iodine, but from a host of other radioactive components including those that are not easy to detect. Tritium will be all over the place and that causes genetic defects, cancer and all sorts of diseases.

To try and play it down in order to establish that the nuclear industry is still viable and that they can still go on building nuclear power stations and so on and to try and talk up the uranium share prices and all that, I think that is criminal. People are going to die as a result of this and they should get people out of there as quickly as possible.

Press TV: You say people are going to die from this. Japanese officials have admitted that there are higher radiation levels in the environment, but say it is nothing more than regular x-rays that people would be exposed to and nothing of significant importance. What would you say to that?

Professor Busby: Criminally irresponsible. After the Chernobyl accident there have been huge increases in cancer and other forms of ill health. And for instance, in Sweden, a study done in 2004 showed there was an 11% increase in cancer in northern Sweden in areas contaminated by the Chernobyl accident. We could get double the amount of cancer in those areas of contamination even without considering the future.

The problem is that the risk model being used in order to make all of these statements is out of date and incorrect. The secretary of the International Commission of Radiological protection has admitted that this risk model is in error by up to 900 fold.

So we know from all sorts of studies that the model is false and doesn't work for the kinds of exposures taking place in Japan now and they should get people away because people are going to get cancer at a much higher rate than is predicted from the risk model.

Press TV: There are reports that iodine will help protect people from the effects of radiation. Does it help and should the Japanese people be taking it?

Professor Busby: Yes. The people should take stable iodine as it will block the absorption of the thyroid gland by radioactive iodine and that will mitigate a lot of the effects of the iodine on causing increases in thyroid cancer. There was a large increase in thyroid cancer in Chernobyl, which has been blamed on iodine. It does help keep the radiation out if you fill yourself up with ordinary iodine. But that's only important for thyroid cancer, which is quite rare.

The cancers that are going to come about as a result of these sorts of releases are going to be increases in breast cancer, leukemia, a whole range of cancers and other ill health as well as congenital malformation and fertility problems that we've seen in the ex-Soviet territories affected by the Chernobyl accident.

Press TV: What about the food aspect? We're getting news about different vegetables and products from the sea that has had radiation detected. The US has banned imports from the area and the EU is trying to control that also.

Professor Busby: What I have to say here will save lives and is very important. People should get stable iodine tablets and give it to the children. Secondly they should try and drink bottled water, bottled before the crisis, or to bring water up from the south, which is pure. Milk should not be drunk. They should not eat any seafood or fresh vegetables, and the food that they do eat should be out of cans.

As long as this crisis lasts, those actions will save a lot of lives.

Press TV: What is the worst scenario?

Professor Busby: That there is an explosion - that enough of this stuff gets together that it forces an explosion and I believe it is possible for that to happen. Other scientists may not agree, but I see it as being possible. There was an explosion in the Mayak facility at KyshTym in the Soviet Union in 1957. It was a nuclear explosion in a spent fuel tank where the same situation happened- the water boiled away, the fuel melted into a lump and then it exploded. And that caused the contamination of about 1,000 square miles of land. This land has been radioactive ever since. If that happens then the material outburst will go all over the place and we have already suspected that some of this material has reached the US.

The best scenario is if it melts and dissipates into the ground, doesn't explode, but makes it very very contaminated. Then they have to pile a load of sand and slate etc on it and fence it off about 100 kilometers away somewhere.

But the problem is that they (Japanese authorities) are saying the radiation levels are low and that people can live outside the 30 kilometer zone. They want to continue making nuclear power stations, mining uranium and making lots of money. It's criminally irresponsible.

中電はその気になれば脱原発が出来る。原発は浜岡だけ、それもかなり老朽化している。

それでも原発を無理やり維持しようとしているのは、日本全体の原子力村の一員だから。つまり経営陣も当事者能力はない。
