Japan uppgraderar kärnkraftsolyckan i Fukushima till en sjua, den högsta nivån på den internationella skalan, bekräftade landets säkerhetsmyndighet på tisdagen, skriver SvD. Den 14 mars skrev TS News att Fukushima var lika allvarlig som Tjernobylolyckan 1986. Uppgifterna kom från den svenske kärnkraftexperten Frigyes Reisch.

fukushima chernobylDet japanska kärnkraftbolaget Tepco bedömde då att haveriet var en fyra på den sjugradiga skalan. Frigyes Reischs respons den 14 mars var istället:

They have economic interests. This is a seven. During my years at SKI, I would not have talked, but now I’m retired and can speak freely.

This is absolutely comparable with Chernobyl. It’s about the impact on a large area with many people and local release of radioactive material that is likely to be the case of lethal doses”.

There is tremendous commercial interest in this. The entire world’s nuclear industry is Japanese.

As an example, he mention the second global nuclear power giant, General Electric Hitachi Nuclear Energy, has Japanese majority ownership. Given all the rescue workers who worked closely with the affected units and inhaled radioactive steam, it´s in reality impossible to not die of radiation. It’s not good.

I do not know how many people who live north of Fukushima, but I guess it is so densely populated that there are a few million,” said Frigyes Reisch.

På tisdagsmorgonen 12 mars lokal tid utbröt en brand intill reaktor fyra i kärnkraftsverket. Japan skakades av ännu ett kraftigt jordskalv med magnituden 6,3 på morgonen 12 mars och på torsdagen den 7 mars hade Japan en jordbävning på 7,4.

Alexej Yablokov: Fukushima kan överträffa Tjernobyl

Alexey Yablokov

Dr. Alexey Yablokov, medförfattare till boken “Chernobyl:Consequences of the Catastrophe for People and the Environment,” och medlem i  ”Russian Academy of Sciences” sa den 25 mars 2011:

“We are seeing something that has never happened – a multiple reactor catastrophe including one using plutonium fuel as well as spent fuel pool accidents, all happening within 200 kilometers of a metropolis of 30 million people. Because the area is far more densely populated than around Chernobyl, the human toll could eventually be far worse in Japan.”

”When you hear [authorities say] ‘no immediate danger’ then you should run away as far and as fast as you can.”

Dr. Yablokov har kalkylerat att så många som en miljon människor dog i Tjernobylolyckan. Dödstalet är betydligt högre än de officiella siffrorna. Yablokov säger att hans bok togs emot med tystnad  av WHO, som konsekvent undvikit diskussioner. Uppgifterna kommer från Commondreams.org.

Med andra ord kan vi förvänta oss kommande och upprepade försök från kärnkraftindustrin att dölja Fukushimas skada på människor och miljö (artikelförfattarens kommentar).

Michio Kaku: Fukushima måste göras om till betongsarkofag

order 0, treat 0,0″>

Michio Kaku som är en amerikansk teoretisk fysiker hävdar att ansvariga för Fukushima använder en helt hopplös metod för att förhindra en härdsmälta. Det är som att försöka stoppa en skogsbrand med vattenpistoler. De måste göra något mycket mer drastiskt, säger Michio Kaku. Det är dessutom självmord att bomba reaktorerna med vatten från helikoptrar på låg höjd på grund av den dödliga strålningen.

Text: Torbjörn Sassersson

Nära 700 ton använt kärnbränsle lagras i de sex reaktorerna i Fukushima och personal vid Fukushimas kärnkraftanläggningen använder vattenbesprutning för att stävja förstadiet till en fullt utvecklad härdsmälta i minst tre reaktorer och sannolikt även i en fjärde reaktor som just nu brinner.

Michio Kaku menar istället att ansvariga snabbt måste ta samma beslut som Gorbatjov vid Chernobyl-olyckan 1986, att kalla in flygvapnet och med helikoptrar gjuta in hela reaktorkomplexet med en blandning av betong, sand och borsyra. Fukushima måste omedelbart byggas om till en sarkofag.

Michio Kaku MSNBC

Michio Kaku born January 24, 1947, is an American physicist, the Henry Semat Professor of Theoretical Physics in the City College of New York of City University of New York, the co-founder of string field theory, and a ”communicator” and ”popularizer” of science. He has written several books on physics and related topics, has made frequent appearances on radio, television and film and writes extensive online blogs and articles.

Fukushima nuclear disaster as bad as Chernobyl according to Nuclear expert

Frigyes Reisch is one of the leading experts on nuclear safety in the world. He worked for 27 years at the Swedish Nuclear Power Inspectorate, stomach SKI. He has worked for the IAEA and with nuclear scientists on know how to judge nuclear incidents. Now he says – in an exclusive interview for Aftonbladet – the accident in Fukushima is as severe as Chernobyl. The release of radio activity is most likely in lethal doses.

The Japanese authorities classifies the disaster as a four on the seven Ines-scale, buy  which means ”an accident without significant risk to the environment”. Reisch dismisses this as a cover-up:

– They have  economic interests. This is a seven. During my years at SKI, story I would not have talked, but now I’m retired and can speak freely.

– This is absolutely comparable with Chernobyl. It’s about the impact on a large area with many people and local release of radioactive material that is likely to be the case of lethal doses,” he says, Aftonbladet reports.

Frigyes ReischINES scale is set by the International Atomic Energy Agency, IAEA, and based on how a nuclear accident may cause risks to human health and the environment. The scale is logaritmic, meaning every step of the scale is about ten times worse than the previous.

The most serious nuclear accident in the world – the one in Chernobyl in 1986 – was classified to a seven.
Since the earthquake and tsunami last Friday, four nuclear power plants in northeastern Japan reported damage. Most serious damage appear to be in the Fukushima Daiichi complex where a meltdown or ”partial meltdown” has been found in Unit 1 and 3.

”The accident should be classified
as the worst on the scale –
Fukushima is as serious as Chernobyl”

 

Frigyes Reisch, 78, is associate professor of nuclear safety at the Royal Institute of Technology (KTH). Over 27 years, until 1997, he worked for the Nuclear Power Inspectorate, SKI. In 1993 he worked a year for the IAEA as an international educator in the INES scale, including in Russia and the Czech Republic. Frigyes Reisch believes that the Japanese authorities blinds the dangers of Fukushima to keep people quiet – but there is also a national scope:

– There is tremendous commercial interest in this. The entire world’s nuclear industry is Japanese.

As an example, he mention the second global nuclear power giant, General Electric Hitachi Nuclear Energy, has Japanese majority ownership.

– Given all the rescue workers who worked closely with the affected units and inhaled radioactive steam, it´s in reality impossible to not die of radiation. It’s not good. I do not know how many people who live north of Fukushima, but I guess it is so densely populated that there are a few million,” said Frigyes Reisch.

So far, winds have been westerly and blowing out the radioactivity of the Pacific Ocean. But according to forecasts, they will during the day today to turn around and start blowing north – with the chance of precipitation. How far the radioactive particles can be spread is due to local conditions. After the Chernobyl accident Gavle, 1000 km from Chernobyl, had most radioactive precipitation in Sweden.
