Fukushima (Japan) nuclear power plant situation
Tokyo (Platts)--13Sep2012/411 am EDT/811 GMT The Japanese government's new energy strategy for the 2030s calls for the shutdown of all nuclear reactors and rely more on power generated using fossil fuels, the Nikkei reported Thursday.

Nuclear Gypsies – The subcontractors who do the dirty work As the six reactors at Tokyo Electric Power Company’s Fukushima power complex have burned out of control over the past week, both the foreign and Japanese press have been full of stories about the “Fukushima 50″ – the several hundred workers who have valiantly, in shifts of 50, struggled to contain the fires and in the process exposed themselves to serious risks of radiation. They have been rightly hailed as the unsung heroes of Japan’s earthquake, tsunami and nuclear catastrophe, as noted by the London Guardian :
Perhaps one day Aiko and Kenji Nomura will laugh about the Birthday Cake Incident.
"Fukushima is the biggest industrial catastrophe in the history of mankind," Arnold Gundersen, a former nuclear industry senior vice president, told Al Jazeera. Japan's 9.0 earthquake on March 11 caused a massive tsunami that crippled the cooling systems at the Tokyo Electric Power Company's (TEPCO) nuclear plant in Fukushima, Japan. It also led to hydrogen explosions and reactor meltdowns that forced evacuations of those living within a 20km radius of the plant.
Scientists and doctors are calling for a new national policy in Japan that mandates the testing of food, soil, water, and the air for radioactivity still being emitted from Fukushima's heavily damaged Daiichi nuclear power plant. "How much radioactive materials have been released from the plant?" asked Dr Tatsuhiko Kodama, a professor at the Research Centre for Advanced Science and Technology and Director of the University of Tokyo's Radioisotope Centre, in a July 27 speech to the Committee of Health, Labour and Welfare at Japan's House of Representatives.
Press Release from NILU The study estimates the emissions of the radioactive noble gas Xenon-133 and the aerosol-bound nuclide Caesium-137 from the Japanese NPP Fukushima Daiichi by combining a large set of measurements from Japan and worldwide, atmospheric transport model calculations, and available information and reasonable approximations on radionuclide inventories and accident events at the Fukushima Daiichi NPP. - Our calculations are based on about 1000 measurements of activity concentrations and deposition conducted in Japan, USA and Europe. This is the most comprehensive investigation so far.
Die vom Norwegian Institute for Air Research erstellte Fukushima-Studie errechnete eine Freisetzung von 16700 Peta-Becquerel Xenon-133 in den Tagen vom 11. bis zum 15. März - den Autoren zufolge "die größte zivile Freisetzung in der Geschichte der Menschheit". Für die bisher wohl umfangreichste Untersuchung haben die Wissenschaftler Daten von rund 1.000 Messungen der Konzentration und Deposition von Radioaktivität in Japan, den USA und Europa herangezogen.
The following is a guest post from TIME contributor Lucy Birmingham. About 100 women from Fukushima, Japan, have started a week-long sit-in at a government office in Tokyo to demand greater protection for children affected by radiation . “Many children and their families are trapped in Fukushima because they can’t afford to move,” explains Ayako Oga, 38, a housewife living in the prefecture and one of the sit-in organizers.
Nach Angaben der Atomlobby hätten die Fukushima-Reaktoren das Erdbeben schadlos überstanden und seien erst durch den Tsunami zerstört worden, so dass es zur Kernschmelze kam. Eine internationale Studie widerlegt diese Annahmen bereits im letzten Jahr und ließ damit an der Erdbebensicherheit aller Meiler zweifeln. Die Reaktoren in Fukushima waren für ein Beben der Stärke 8,0 bis 8,3 ausgelegt worden.
Anderthalb Jahre nach der Atom-Katastrophe redet die Regierung die Lage schön und kauft sich die Ärzte, die die Strahlenbelastung für unbedeutend erklären.
Some 8 percent of Japan's land area, or more than 30,000 square kilometers, has been contaminated with radioactive cesium from the crippled Fukushima No. 1 nuclear power plant. Spanning 13 prefectures, the affected area has accumulated more than 10,000 becquerels of cesium 134 and 137 per square meter, according to the science ministry. The ministry has released the latest version of its cesium contamination map, covering 18 prefectures.
