The government on Tuesday released a report on the accidents at Fukushima No.1 nuclear power plant. Submitted to the International Atomic Energy Agency, the report describes 28 lessons and countermeasures.
The government and the power industry should act quickly on recommendations derived from the report. The report, though, should not be used as an excuse to continue Japan's relatively high dependency on nuclear power.
Showing that the Fukushima accidents are much more severe than generally believed, the report points to the possibility that "melt-through" incidents occurred at the Nos. 1, 2 and 3 reactors — with molten nuclear fuel passing through the bottom of the pressure vessels and collecting at the bottom of the containment vessels.
