Radiation reached around 20 times normal levels in the capital Tuesday morning, the Tokyo Metropolitan Government said, while offering the assurance this reading posed no immediate risk to human health and that the public should remain calm. “I received a report this morning that there was an important change of data,” Gov. Shintaro Ishihara said at a news conference.
Govt, TEPCO fail on info-sharing / No N-crisis HQ for 4 days after tsunami disabled reactor cooling systemThe Yomiuri Shimbun Both the government of Prime Minister Naoto Kan and Tokyo Electric Power Co. failed to exercise a firm grip over the release of information on the rapidly unfolding nuclear crisis at the utility's nuclear power plant in Fukushima Prefecture, and did not set up an integrated government-TEPCO headquarters until Tuesday, four days after the outbreak of earthquake-triggered abnormalities.

At Oehmen’s request the original post was checked for technical accuracy, revised and moved to mitnse.com. The revised essay serves as a general summary of the events during the first 24 hours after the earthquake and tsunami struck the Fukushima Daiichi power plant on March 11, 2011.
Russian nuclear authorities said a Chernobyl-type disaster was unlikely to happen at the stricken nuclear plant in Japan, but experts refused to rule out this scenario. “There can be no replay of Chernobyl at the Fukushima nuclear plant,” said Sergei Novikov, official spokesman for the Russian nuclear corporation Rosatom. “The worst case scenario in Japan is what happened at the Three Mile Island nuclear plant in the U.S. in 1979, where fuel melted down but stayed inside the reactor.”

[UPDATE: 5:59 PM ET: The evacuation zone around the power plant has been increased to 10 km, or 6.2 mi.] [UPDATE: 5:46 PM EST: Japanese authorities announced that radiation inside the stricken Fukushima power plant control room has risen to 1,000 times its normal level. Some has leaked outside of the plant, prompting calls for further evacuations beyond the 3,000 people who have been cleared out already in a 1.8-mi. radius.
Authorities scrambled Sunday to control an overheating reactor at the problem-prone Fukushima No. 1 nuclear power plant by injecting seawater and venting gas to reduce the pressure inside. While acknowledging that the core of the plant’s No. 3 reactor may have overheated and deformed, Chief Cabinet Secretary Yukio Edano denied it led to a meltdown of the critical fuel rods. At a news conference, Edano said that “a very small amount” of radioactive substances had leaked from the No. 3 reactor, dismissing concerns it posed a threat to human health.
Japanese authorities began evacuating more than 200,000 people Saturday from areas around two nuclear power plants after an explosion at one of them damaged a building housing an aging U.S.-supplied reactor.
