Arnie Gunderson explains that at least in reactor #2 (and maybe #3) the fuel pellets are melting THROUGH the bed of the nuclear reactor. I do not know what that means but it doesn't sound good and seems to portend continued and perhaps increased releases of radioactive steam that will circulate around the northern hemisphere.

MEANWHILE Japan plans on raising the level of nuclear disaster from a 5 to a 7
"Japan may raise nuke accident severity level to highest 7 from 5 TOKYO, April 12, Kyodo
The Nuclear Safety Commission of Japan released a preliminary calculation Monday saying that the crippled Fukushima Daiichi nuclear plant had been releasing up to 10,000 terabecquerels of radioactive materials per hour at some point after a massive quake and tsunami hit northeastern Japan on March 11. The disclosure prompted the government to consider raising the accident's severity level to 7, the worst on an international scale, from the current 5, government sources said. The level 7 on the International Nuclear Event Scale has only been applied to the 1986 Chernobyl catastrophe
