Japan nuclear reactor has fatally high radiation, no water —Tuesday's examination with an industrial endoscope detected radiation levels up to 10 times the fatal dose inside the chamber. 27 Mar 2012 One of Japan's crippled nuclear reactors still has fatally high radiation levels and hardly any water to cool the No. 2 reactor, according to an internal examination Tuesday that renews doubts about the plant's stability. Plant officials previously said more than half of melted fuel has breached the core and dropped to the floor of the primary containment vessel, some of it splashing against the wall or the floor. Particles from melted fuel have probably sent radiation levels up to dangerously high 70 sieverts per hour inside the container, said Junichi Matsumoto, spokesman for Tokyo Electric Power Co.
Fukushima Pref. deleted 5 days of radiation dispersion data just after meltdowns 22 Mar 2012 The Fukushima Prefectural Government revealed on March 21 that it deleted five days of early radiation dispersion data almost entirely unread in the wake of the meltdowns at the Fukushima No. 1 nuclear plant. The data from the System for Prediction of Environmental Emergency Dose Information (SPEEDI) – intended to predict the spread of radioactive contamination, information vital for issuing evacuation advisories – was emailed to the prefectural government by the Ministry of Education, Culture, Sports, Science and Technology. The Nuclear Safety Technology Center sent the data hourly starting at 11:54 p.m. on March 12, 2011 – one day into the nuclear crisis. The Fukushima Prefectural Government, however, deleted all the data it received from March 12 to about 9 a.m. March 16.
