日核電廠安全殼輻射足致命

日核電廠安全殼輻射足致命

東京電力公司周二表示,在對福島第一核電站2號機組反應堆安全殼內的輻射濃度極高。
公司進行調查時,測得安全殼內了每小時有31.1至72.9希沃特的強輻射。有分析認為,這可能是由於熔化的燃料穿透壓力容器,落入了安全殼底部所致。
人類受到7希沃特輻射後一個月內就會死亡,超過20希沃特則在數日內死亡。以2號機組目前的輻射水平,人類無法入內作業。東電原子能及選址代理本部長松本純一表示:「將繼續調查並分析輻射分佈情況,就反應堆報廢所需器材展開研討。」
東電26日向2號機組安全殼內插入內視鏡調查了水位。27日則通過安全殼的同一貫通口把輻射測量儀向下插入了約3米,在距安全殼底部4至7米、距內壁50至100厘米的8個點測定了輻射值。
在距安全殼內壁約100厘米處,越接近底部則輻射值越大。松本表示,不知道這是因為落入底部的燃料,還是因為飄起的放射性物質的影響。熔化掉落的燃料應該全部浸在水中。

末日機器-對人類的三重威脅

The Doomsday Machine -- Triple Threat to Humanity

Dees Illustration
Andrew McKillop Activist Post

1950s Vanity Tech

In our book published by Palgrave Macmillan, my co-author Martin Cohen (author of Mind Games and Philosophy for Dummies) and myself line up the reasons why we say The Doomsday Machine of nuclear power has grown ever more dangerous.

We explain why and how it spiraled out from early military origins to become an over-rated, dangerous and expensive source of electricity, mostly in the developed countries.

And, now, in its last format it has morphed into a threat to global security, starting with the world's financial and economic security, and the risks of nuclear proliferation, but also including the biggest, most vast Dirty Bombs imaginable, stationed close to dozens of the world's major cities.

This bad story has to end one day. It may be soon, it may be later, but as we explain the selling of the atom is big business, relentlessly exploiting all kinds and types of weaknesses in the human psyche. The sales show has to go on, but when the end does come, it can and will be a bad ending.

Nuclear power grew and grew, like the cancers its radiation causes. It leaves behind a terrifying sting in its tail. For more than 60 years, it has been promoted as something for nothing which would deliver electricity so cheap, clean and safe that all other and previous forms of electricity production would be abandoned -- possibly with the exception of hydropower, and more recently wind power and solar power. The risks, hazards and real costs of nuclear power were, and still are carefully hidden, talked around, or simply ignored. Ignorance is bliss, but try asking the hundred thousand victims of Fukushima how they feel. Try asking the hundred thousand victims of the Chernobyl catastrophe. Each of these disasters have caused, or will cause $200 or $300 billion of economic damage.

Nuclear power promoters sell the Friendly Atom as man's best friend -- and in some future fantasy version, as our only and last friend when the fossil fuels disappear. Building reactors everywhere is our stepping stone to an all-new energy future, our defense against oil depletion, a key move in countering unreliable foreign suppliers of energy, holding us to ransom with their high-priced oil, gas and coal.

Never mind if these claims have always been exaggerated. Don't expect truth from promoters of the Friendly Atom. When nuclear power suffers its all-too-regular disasters; when they happen and are so big they can't be yanked out of the business-friendly media after 48 hours, nuclear promoters go into quiet mode.  Not long after, however, the promoters will bounce back touting the same snakeoil, expounding the same patter, the same story -- like politicians saying this time things are really going to change for the better. You have to believe. If you are stupid enough.

Swords to Ploughshares and Back Again

WWII made it look or seem that mankind -- at least the US, then the Soviets, British, French and Chinese -- had mastered the atom. They made terrifyingly powerful bombs, but this also looked like a way to get so much energy from so little fuel that Dwight Eisenhower's 'Atoms for Peace' would mega-shift mankind into a totally new world of almost free energy. What happened was different: the enduring nuclear partnership between industry and big government started shifting huge hidden subsidies from the governments of the then-rich and growing consumer democracie; and the USSR, into building wildly expensive Rube Goldberg (for Brits: Heath Robinson) generators far away on the skyline.

Nicely remote, pumping out electricity that only seems cheap when the figures are distorted the right way, the subsidies are hidden -- and frighteningly expensive reactor decommissioning "never happens" because it is so far in the future. In 1955 it seemed that 2012 was centuries ahead.

To be sure, nuclear power's massively dangerous wastes piled up. These wastes provide all and any nation with nuclear power, and engineering capabilities equal to those of US industry in the early 1940s, when cars were still produced using wood, hand-beaten metal, catgut, and animal varnish, to produce atomic weapons equivalent to the 1940's Manhattan Project. Just ask the Israelis, Indians, Pakistanis and North Koreans. But much more simply, today's terror organizations can simply take out and destroy the Dirty Bomb reactors located in enemy nations -- anyway and anywhere they want.

In the 1950s and 1960s things seemed different. At the time nuclear power supplied 0% of world energy. It was set to grow and grow for the benefit of all. Today it supplies about 3% of world energy or 14% of world electricity. Is it worth it?

Technological advances have made nuclear plants certainly more expensive and possibly a little less dangerous, but that isn't the same thing as safe. A worst-case nuclear reactor accident isn't comparable to anything else -- even the devastating Bhopal and Seveso pesticide factory explosions. But it is comparable to a military nuclear strike, because after it thousands of square miles are contaminated for decades with cancer-causing radiation. Everybody knows this. The nuclear industry, its apologists, and its friends in government and the media deny this.

When It Goes Right, It Goes Wrong

When reactors behave right, disposing their nuclear waste remains an insoluble problem. Everybody can check up the long, bad-joke story of the US Yucca Mountains "final repository", which never happened. It was too expensive. It was abandoned by the Obama administration after decades of playacting and ever rising costs. For nuclear waste there is in fact no solution, so massive amounts of poisonous radioactive debris are piling up, and will go on piling up around us. Technology optimists, to be sure, have a huge wishlist of pet projects to supposedly solve the problem. These always-expensive, never-built "solutions" are used by nuclear promoters to pretend all problems will be solved or controlled. You have to believe.

More unsettling, the financial industry's most nimble-brained liars -- the same who gave us the subprime and sovereign debt crises -- have taken up hard-selling the atom. Poor nations with a high risk of civil war and rather unimpressive government oversight (including Nigeria, Indonesia, Bangladesh, the two Sudans, Algeria, Egypt, even Libya of the Gaddafi era) claimed or go on claiming they are jumping on the nuclear bandwagon just as soon as possible. The financing is secure, their Western financial advisers say. It is the only way forward, you know.

Sadly, the global warming and CO2 issue served as a litmus test for the environmental movement, winnowing out a loud and self-important faction saying nuclear power is the only practical way to reduce carbon emissions. Following the Fukushima disaster some have gone quiet, even recanted and denied their love affair with the friendly atom, and shifted back to talking solar energy and wind power. But these alternatives to the atom spin the dials on the finance industry's cash registers almost as fast as atomic energy snakeoil: offshore windfarms and square miles of solar power plants are the new big ticket, high-priced Energy Vanity Tech of the post-2000 era.

In turn, never missed by nuclear fundamentalists as they tiptoe back in the media to sell their poison, solar and windpower remain hopelessly unable to entirely and efficiently replace our current fossil-based energy sources and systems. Hydroelectric dams often flood valuable land and damage the environment; biofuels convert food crops to diesel fuel and gasoline substitutes, raising food prices and gulping huge quantities of water; nuclear fusion power is pie-in-the-sky.

We are told we must get used to nuclear power because it is the only real alternative to declining and depleting oil supplies, and polluting coal energy whose supplies aren't so massive as plenty pretend. Even the shale gas boom will only stretch gas supplies a certain time, but this is a new-old story.

Listening to it, we could be anywhere in time, whether the 1956 UK Winscale disaster, the 1979 US Three Mile Island disaster, the 1986 Russian Chernobyl disaster. Nuclear power certainly travels down the ages, and each time a disaster happens we will get those comfort studies on nuclear risks: the famous US Rasmussen report of the 1970s told us the chance of a nuclear accident, like Three Mile Island which happened a few years later, is once every 30,000 reactor years.

When It Goes Wrong -- It Goes Badly Wrong

Nuclear power is a permanent disaster. Producing its uranium fuel is an environmental disaster -- now tucked and folded over the horizon in mostly-poor countries where miners are paid $5 a day and unprotected against radiation. Building reactors is a financial disaster, always shifted to government subsidies. Waste disposal is both an environmental and economic disaster. When the fateful time comes to decommission the Doomsday Machines, after the easy 10-year life extensions run out, this is another economic disaster. But when a reactor becomes what it really is -- the most massive Dirty Bomb you or Bin Laden (radhi Allah anhu) can imagine -- the nuclear disaster will be hard to yank out of the media, quicktime, and carry on like nothing ever happened.

It will mark the turning point. As we know, president Sarkozy of France -- the most nuclear-intensive country in the world and officially proud of it -- was a prime mover in the 2011 regime change war against Muammar Gaddafi. In December 2007 at the Elysees Palace with Gaddafi's Bedouin tent and Mercedes bulletproof limos outside the palace for the duration, the same president Sarkozy was trying, real hard, to sell Muammar Gaddafi nuclear technology. One Areva power plant, maybe two of them. Unbelievable but true. To be sure we could take some magic mushrooms and dream, along with the nuclear apologists and their financial partners that war is finished. It doesn't exist anymore. Even civil wars, in Libya and Syria for example, are waged by persons who never, ever would think about targeting their enemy's nuclear power plants. Although they know that each full-size reactor contains as much radiation as 150 Hiroshima-size bombs, they simply wouldn't do that. You have to believe.

Outside war (which we know doesn't exist anymore), the war on our living standards, incomes and buying power will soon go into high gear in the Nuclear Nations, nearly all of them OECD, mature post-industrial democracies trying to get a grip on their sovereign debt disasters. Large-scale decommissioning will have to start soon. In the 12-year period to 2025 several dozen will go into decomm and Safestor and the price will be high -- so electricity prices will fly. At the very same time, by a strange process of mass schizophrenia, we are also told we have to make an almost instant Energy Transition away from oil, coal and natural gas, to always-more-expensive renewables, to save us all from Climate Crisis. Along with expensive renewable energy, we can have nuclear power, in the furthest out and most expensive Low Carbon transition plans. All we know is the costs will be out of sight. Truly out of sight.

As our book tries to point out without going viral, the credibility of these energy fear plans and fantasies is so low that we have to ask why anybody takes them seriously, or pretends they take it seriously. What we can be sure of is this: nuclear power is going to be a mover in the needed process of rediscovering and understanding that reality is....real. We can hope the nuclear wake-up call will not be a pure and simple disaster, like the experience for nearly 100,000 Japanese thrown out of their homes, farms, factories and schools, probably forever and at least for decades by the 4-reactor meltdown at Fukushima.

We can sincerely hope it will only be an economic and financial disaster -- just one more, to add to the rest, and probably manageable. We can hope.

We can hope, but the clock ticks on. The world's reactors are aging. The uranium runs out. The wastes pile up. The risks, already high, go on growing. The Doomsday Machine.

福島核電廠漏水 無入海之虞

(路透東京30日電)東京電力公司(Tepco)和日本媒體指出,遭重創的日本核電廠週末漏水逾600公升,被迫暫時中止廢燃料池冷卻作業,但漏水無流入海中之虞。
負責營運福島核電廠的東電昨天在網站上回報發生2起漏水事件,1起發生於核電廠辦公大樓附近幫浦,另1起發生於4號反應爐後備冷卻系統。
東電就4號反應爐事故表示:「冷卻用水從消防濾液桶流出,不包含放射性物質」,並指出他處部分漏水已流入排水管,「我們正在檢視這些漏水是否流入海中。」
「日本經濟新聞」今天引述東電說法,報導4號機燃料池冷卻系統昨天早上漏水約40公升,另處可能漏出600公升純水,且核電廠內其他設備可能也發生漏水。
不過據日經報導,東電認為沒有任何漏水流入海中。
日經引述東電說法報導:「漏水原因是冷卻水凍結,漏水包括淨化過的放射性汙水,汙染程度很低。」中央社(翻譯)url

福島核電廠1-3號機組放射性物質增加


東京電力公司表示,福島第一核電站1至3號機組釋放的放射性物質,為每小時0.7億貝可,較去年12月的0.6億貝可增加。
東電認為,2號機組內視鏡調查的準備及3號機組附近的解體作業,導致放射性物質飛揚。
東電表示,1號機組的釋放量,降至去年12月的五分之一,但2和3號機組,分別增加0.1億貝可。
另外,公司還宣布,將新設多核種除去設備,設備除了能去除核污水中的銫,還能去除其他約一千種放射性物質,期望進一步減低水中放射性物質。

日農:被迫種輻射米 受污農地無賠償

【明報專訊】日本3.11大地震及核災發生近一年後,再揭後遺症。爆發核泄漏事故的福島第一核電站周邊米農自行檢驗稻米收成,揭發所含放射性銫超出 政府安全水平,反映農地已受污染。有農民直指政府及東京電力不願賠償,令他們別無選擇,明知農地受污染仍「被迫」繼續耕種維持生計,令國民冒險吃輻射食 品。
去年秋季,日本政府在距福島核電站西北56公里的福島縣大波地區,從當地154戶米農中抽取兩戶出產的稻米測試,宣稱當地出產稻米可安 全食用。但當地農民對結果存疑,有人不敢讓到訪的孫子吃自己種的米,拿去檢驗後發現稻米所含放射性銫超出每公斤500貝克的安全水平。農民指出,由於東京 電力公司僅向核電站方圓20公里的農戶全數賠償,在撤離圈外的農民被迫繼續種植可能含有輻射的作物以維持生計,別無選擇。
福島稻米放射銫超標
日 本政府早前答應全面測試福島縣逾2.5萬戶米農的作物,以消除公眾對輻射米的恐慌。當局至今在福島核電站西北等核污染較嚴重的地區抽取近5000個樣本測 試,約五分之一稻米含有放射性銫,大部分屬安全水平,只有30個樣本銫含量超標,不過厚生省將在今年4月採用新輻射安全標準,稻米的放射銫含最多為每公斤 100貝克,以此標準則約300個稻米樣本超標。
農業官員承認,輻射污染物隨風四散,隨機抽樣不足以確保所有農作物安全,但由於檢測儀器不足,無法檢測全部農產品。官員亦稱,儘管公眾質疑是否應容許繼續耕作核電站附近的農田,但停耕將令耕地大幅減少,影響食物供應。
事 件再次揭示日本食品輻射檢測欠透明度。許多日本民眾相信,政府淡化甚至隱瞞輻射對公眾健康的風險,以盡量減少劃定受災地區的規模,減少經濟損失及賠償金 額。東京慶應大學經濟系教授深尾光洋指出,日本政府在震災後以「如常運作」的策略淡化事件,但網上信息流通,令民眾了解到官方檢測不可信賴。有志願機構在 全國設立多個檢測站,作更嚴格、透明度更高的測驗,希望贏回消費者信心。

日福島逾百樓宇料受核污染

隨著災後重建中住宅需求的增加,日本福島縣使用了疑似核污染石料的住宅很可能超過100棟。
據相關人士22日透露,日本福島縣內至少有60棟公寓樓和獨戶住宅使用了該縣浪江町碎石工廠出產的核污染石料。
經濟產業省將盡快查明這些石料的流通路徑,並優先調查在福島縣內各生活區的使用情況。據福島縣政府調查,縣內179個災民臨時安置點均未使用疑似污染的石料。
目前已經查明這些石料在福島縣內兩家混凝土公司(其中一家已經解散)被加工成混凝土,去年3月福島第一核電站事故發生後已被用於縣內的住宅、道路、河堤等近千處地方。
供應這些石料的雙葉碎石工業公司的社長豬狩滿表示:「因災後重建需要碎石,所以便出貨了。」

Plutonium From Fukushima Has Now Circled The Planet

Sayer Ji, Contributing Writer
Activist Post

A recently published study in the Journal of Environmental Radioactivity confirms that the radioactive fallout from the Fukushima nuclear disaster reached Europe (Lithuania), and included plutonium, the most deadly manmade element (nanogram for nanogram) in existence.

According to the study's authors the radionuclide concentrations measured indicate there was "long-range air mass transport from Japan across the Pacific, the North America and the Atlantic Ocean to Central Europe as indicated by modelling."

What this means is that every region under the jet stream -- which includes half of the planet north of its equator -- could have been exposed to some degree of plutonium fallout.

This fact is all the more disturbing when we consider there is no such thing as a safe level, and that the harm (on the human scale of time) does not dissipate: the half life of plutonium-239 is 24,200 years, and that of uranium-238 is 4,460,000,000 years, which is older than our planet.

In a past exposé, where we identified the likelihood of the occurrence we are now reporting on, we published Jet Stream radiation dispersion projections from Germany's EURAD system which showed that Radioiodine-131 and Cesium-137 were within detectable concentrations thousands of miles away from Fukushima within days after the event.

This was, after all, a nuclear explosion (as occurred also at Chernobyl) producing extremely small particles moving at extremely high velocity, and not a hydrogen-based conflagration, which was erroneously reported to be the case in the first days following the disaster.

福島核燃料或已穿透一號反應堆底部混凝土


日 本福島第一核電站的核洩漏情況嚴峻,東京電力發表數據顯示,一號反應堆內的核燃料可能全部穿透反應堆底部的混凝土,深達六十五厘米左右,距離外圍最薄處只 有三十七厘米。另外,統計表明,二號反應堆內可能有五成七,三號反應堆有六成三的核燃料,掉落到安全殼底部,高濃度輻射污水,從安全殼流出的可能性非常 大,令工作人員將核燃料從容器安全取出,增加很大難度。
另外,東電在福島第一核電站港口海底的土壤,檢測出每公斤有八十七萬貝可的放射性銫137,估計是四月高放射性污水外洩造成。東電聲稱,裝設的擋板,阻止污水流出港口,污染不會擴大。

專家稱: 福島失控

2011年12月9日 17:37:06
Radiation monitoring, Fukushima City
While walking through the highly contaminated outskirts of Fukushima City last week, I suddenly realized that this capital of the prefecture is as far from the Fukushima nuclear disaster site as my hometown is from Borssele where the only Dutch nuclear power plant in the Netherlands is located —about 60 km. While people in the 20 km exclusion zone around the Fukushima disaster site have been evacuated, the residents of this densely populated city have already waited nine months for decontamination of their houses, gardens and parks without getting any official government support for relocation, not even for children and pregnant women.
We spent four days in Fukushima City doing a radiation survey in the neighbourhoods of Watari and Onami. People there have been left to cope alone in a highly contaminated environment by both the local and national governments. Our radiation experts found hot spots of up to 37 microSieverts per hour in a garden only a few meters away from a house and an accumulation of radioactivity in drainage systems, puddles and ditches. Overall, the radiation levels in these neighbourhoods are so high that people receive an exposure to radiation just from external sources that is ten times the annual allowed dose. How high their internal exposure is from eating contaminated food and inhaling or ingesting radioactive particles remains unknown, since no government program is keeping track of this.
 Parks are the most contaminated areas in Fukushima City. Some are marked with signs: “Due to radioactive contamination, don’t spend more than one hour per day in this park.” Even on sunny days last week, the parks where empty. Mothers are smart enough to not let their children play on the playgrounds in these parks, not even for an hour. Even inside their houses, they have to worry about radiation. We measured the rooms of an elderly lady’s house who is expecting her grandchildren for Christmas. She wanted to know what the safest place was for her grandchildren to sleep.
People in Fukushima City are worried about their health, especially families with children and pregnant women. We walked around with dosimeters and radiation detection equipment and were aware of what we are exposed to and of the risk we were taking. The residents of Fukushima City had one government survey at their house last July, if any at all. Detected hotspots where left unmarked, no instructions were given on how to behave in a radioactive environment. Since then, only 35 of the thousands of houses that need to be decontaminated have been cleaned by the government.
The decontamination done by the local authorities is both uncoordinated and thoroughly inadequate. The subcontractors they are using are badly instructed, risking their own health and spreading the radioactive contamination instead of removing it. We found radioactive run-off water from a decontamination process leaking directly into the environment. And because there is no storage site for radioactive waste from decontamination work, the waste is buried directly on people’s property, sometimes only a few meters away from their houses.
The Japanese government doesn’t know how to deal with the massive contamination caused by the nuclear disaster. Instead of protecting people from radiation, they are downplaying the risks by increasing the allowed radiation levels far above international standards. And professors like Dr. Yamashita, who make statements like ‘If you smile, the radiation will not affect you’ are being employed as official advisors on radiation health risk.
In short, it is clear that the situation in Fukushima is rapidly spinning out of control, and if the national government does not take full responsibility for the protection of its population, the people affected by the triple meltdown at Fukushima Daiichi will continue to suffer for a long time to come.

福島核站燃料棒全熔解

【明報專訊】日本政府及東京電力公司周三發表報告,首次估計福島第一核電站1號反應堆的核燃料棒已完全熔解。報告指,根據最新的模擬測試數據,估計 熔解的核燃料已燒穿1號反應堆的壓力容器,安全殼底部的水泥層亦部分被燒毁。東電稱該水泥層厚約2.6米,估計核燃料已燒穿0.65米(即厚度約75%) 的水泥層,有可能燒至兩米深,但估計不會燒毁外層鋼殼,而鋼殼外尚有7.6米厚的水泥層基座,可阻擋核燃料穿破反應堆流出地面。
有關報告是自311大地震後,日本政府及東電就核事故發表的最嚴峻評估,顯示福島核事故的嚴重程度有許多未明之處。國際核專家在核災發生後數星期已估計核燃料棒完全熔解,日方的報告足足遲來6個月,被斥反應緩慢,意圖淡化核災嚴重性。

輻射物 10天繞地球一周

福島米 含銫超標遭禁售

(東京十七日電)日本氣象廳的研究小組十七日發表福島核災事故模擬實驗結果,顯示由福島核一廠外洩到大氣中的放射性物質,在災後約以十天時間環繞地球一周,其中七到八成的放射性銫落入海中,僅有三成落在陸地。

日本氣象廳氣象研究所的模擬實驗發現,放射性物質隨偏西風及低氣壓升至太平洋上空,並向北飄浮,穿過俄羅斯東岸及阿拉斯加地區後,大概在三月十七日抵達美西,三月二十四日左右環繞地球一周,前後大概只有十天時間。研究小組並推算出截至四月底,約有七到八成的放射性銫落入海中,掉落在陸地上的輻射物質則多半集中在福島及其附近土地。

九月到十月間曾接受全縣抽驗、並宣布「安全無虞」的福島縣稻米,已再度亮紅燈。福島市大波地區新產的「越光米」糙米,被驗出每公斤含放射性銫六三○貝克,高於五百貝克安全上限,十七日遭農林水產省下令禁售,成為核災發生以來首批被禁售的稻米。

福島核放射物或擴散到中國及北海道沉積土壤

一項國際研究顯示,日本福島第一核電站三月發生核洩漏事故後的一個月,核放射物可能擴散到北海道和中國等地,並沉積到土壤。
報告由名古屋大學等組成的國際研究小組發表,他們在中國及在北海道東部地區的土壤中檢測到每公斤二十五至二百五十貝可的放射銫137;小組指,這樣的放射量,不會對人體構成傷害,不需要清除輻射塵,但日本政府有必要在全國開展同類調查,了解各地核輻射情況。

東電社長自爆核電超貴(劉黎兒)

2011年 10月31日

今年6月上台的東電社長西澤俊夫,在接受《東洋經濟週刊》訪問時舉手投降,自爆「核電若連連賠償的話,費用超貴的!」核電即使不包括核災賠償也是所有發電方式中最昂貴的,現在已經逐漸成了世界共同認識,美國也有業者為成本太貴而取消新建,但被東電社長自己吐出「超貴」這兩個字,還是因為東電這次不得不面對核電的幾個無限成本的疙瘩了。
東電社長自爆核電真相又大聲求饒,是因所屬福島核一發生核災,其結果如京都大學原子爐學者小出裕章所說的「東電破產多少次,日本政府破產多少次,都賠不起的!」東電賠不起,西澤說:「核電的風險不是區區民間企業所能承擔的!」想把責任推給長年推進核電的政府。
收拾核災費用驚人,日本原能會在10月28日承認要收拾面目全非的福島核一3爐7池需要30年以上,這是超樂觀估算,因為收拾下落不明爐心(核燃料棒)的方法尚未開發,加上第2石棺、第3石棺等建設,百年都收拾不了,當下估測的收拾費用是7兆日圓以上,但專家估測將會是數十兆日圓。
擁核者嫌貴擺爛

收拾核災最重要的工作之一,是把從福島核一飛散出去的輻射物質除卻、回收,亦即除卻輻射污染,根據東京大學教授兒玉龍彥估計,單單土壤等環境除污,最少得花800兆日圓,相當於日本10年的國家預算,每個日本人至少要負擔600萬日圓,現在日本國民總資產估價為1000?1400兆日圓,但國家負債1000兆日圓,800兆日圓將會導致日本破產;兒玉的基準是輻射劑量在1毫西弗╱年以上的地方都應該除污,因為IAEA或日本災前普通人輻射容許基準就是1,擁核經濟學者池田信夫則認為5毫西弗以上的地方除污就好,其實不管1或5都是只算銫137,若連其他輻射物算更不僅此數;但即使如此,池田估算除污需要118兆日圓,嫌太貴,因此主張乾脆不要收拾算了,這就是擁核者臨頭留下爛攤子不管的真面目。
其他房產及產品價值的消失等更是以千兆日圓單位計,要賠至少得賠數十兆至數百兆日圓,東電或日本政府賠不起,都想少算1個零或2個零了事,日本政府在10月初估算東電到2013年3月要支付4.5兆日圓,東電社長現在就為了調度賠償資金叫苦連天,才會吐露核電超貴。
核電除普通發電成本就是最貴外,若發生核災,則費用不堪,這是擁核政府及業者至今都不敢去面對的疙瘩之一,只能假定核災不會發生,甚至不准研究核災對應措施,是不能碰觸的禁忌,如果一碰觸,核電成本算不完;與此相關,最精明狠心的保險業者,誰也不敢承保核電險,歐洲曾有業者試算過,若真的投保,則核電每度成本將會是120歐元,亦即4500元台幣。
輻射物禍害子孫

即使沒發生核災,核電後端的費用不斷在上升,從美、法例子,已確定廢爐會花造爐的2倍費用,就像核四續建最後要花3200餘億元,是世界最貴核電,廢爐就要6千億;而擁核當局還不敢碰觸、面對的另一個巨大疙瘩,是遺毒10萬年甚至百萬年的核廢料問題,這是至今無解而已經燙手的問題,代價更不是錢能計算的,即使台灣現在廢核,我們也已經有了23萬顆廣島原子彈份的核分裂生成的輻射物質,要讓我們自己及子孫承擔;核電當局有這麼多疙瘩不敢碰觸,還能讓他們繼續強迫大家擁抱核電嗎?
