Molten cores have melted through Fukushima reactor pressure vessels
Three months after the Fukushima nuclear catastrophe began on March 11, Tokyo Electric Power and the Japanese government have finally admitted that reactor cores in Units 1, 2, and 3 likely completely melted down and that molten nuclear fuel melted through the bottom of the thick steel reactor pressure vessels just days into the accident. Still out of control, the Fukushima units will likely continue large-scale radioactive steam releases into the environment for a year or more.
Desperate efforts continue to try to prevent multiple storage pools from boiling dry to prevent high-level radioactive waste from igniting and releasing its deadly contents directly into the winds and waves. Officials have also doubled the estimates of radioactive releases, without explanation for the earlier error.
