– Melted Fuel at Fukushima May Have Leaked Through, Yomiuri Says (Bloomberg, June 7, 2011):
The melted fuel at Tokyo Electric Power Co.’s Fukushima Dai-Ichi nuclear power station may have leaked through the pressure vessels of the Nos. 1 to 3 reactors, the Yomiuri newspaper reported.
The Japanese government will submit a report to the International Atomic Energy Agency that raises the possibility the fuel dropped through the bottom of the pressure vessels, a situation described as a “melt through” and considered more serious than a “meltdown,” according to the report, which cited the document.
