Nuclear fuel has melted through base of Fukushima plant
The nuclear fuel in three of the reactors at the Fukushima Dai-Ichi nuclear plant has melted through the base of the pressure vessels and is pooling in the outer containment vessels, according to a report by the Japanese government.
The findings of the report, which has been given to the International Atomic Energy Agency, were revealed by the Yomiuri newspaper, which described a "melt-through" as being "far worse than a core meltdown" and "the worst possibility in a nuclear accident."
A spokesman for Tokyo Electric Power Co. said the company is presently revising the road-map for bringing the plant under control, including the time required to achieve cold shutdown of the reactors.
In a best-case scenario, the company says it will be able to achieve that by October, although that may have to be revised in light of the report.
