Fukushima Daiichi Unit 2 fuel core meltdown reported underway

7:39AM EST March 14---We have received a report from our Japanese colleagues that Tokyo Power Electric Company is reporting that Fukushima Daiichi Unit 2 has lost all cooling water and the fuel core is completed exposed. The fuel rods are very likely melting. There is no word on efforts to flood Unit 2 to avert an uncontrolled meltdown.

Two hydrogen gas explosions have already rocked Unit 1 and Unit 3. A third explosion is now likely in Unit 2 potentially releasing significant amounts of radiation into the atmosphere if the vessel fails followed by containment failure as the result of a possible full scale meltdown.
