Japan Update June 7, 2011

3 nuclear reactors melted down after quake, Japan confirms  From CNN via Rense.

Japan's Fukushima Daiichi nuclear power plant experienced full meltdowns at three reactors in the wake of an earthquake and tsunami in March, the country's Nuclear Emergency Response Headquarters said Monday.The nuclear group's new evaluation, released Monday, goes further than previous statements in describing the extent of the damage caused by an earthquake and tsunami on March 11.
The announcement will not change plans for how to stabilize the Fukushima Daiichi plant, the agency said.
Reactors 1, 2 and 3 experienced a full meltdown, it said.
The plant's owner, Tokyo Electric Power Co., admitted last month that nuclear fuel rods in reactors 2 and 3 probably melted during the first week of the nuclear crisis.

Fukushima: Twice As Bad As Thought via Rense.

One recurring theme that has emerged after Fukushima is the tendency of nuclear experts to underestimate (publicly at least) the severity of the disaster. Today we received further proof of this when the Japanese government more than doubled the estimate for the amount of radiation released from the plant in the immediate aftermath of the crisis in March.

Government watchdog The Nuclear and Industrial Safety Agency also said that the meltdowns of the plant's reactor cores--at least one of which we now know suffered a total meltdown—happened much more quickly than Tepco has previously suggested, making it clear that the plant operators' desperate attempts to cool the reactors by dumping sea water on them were largely unsuccessful.
