Estimation of Nuclear-Energy Excursion Possibility during Fukushima-1 NPP Accident

BACKGROUND

On March, 11th 2011, Japan has suffered from the strongest 9 magnitude earthquake and a destructive tsunami. The

NPP Fukushima Dai-ichi (Plant 1) was in

an impact zone of the

tsunami. Originally, station reactors did not suffer and

were automatically shutdown at the moment of the earthquake. However, owing to shutdown of the centralized power

supply and damage of backup diesel generators, the supply of cooling water in the reactors was stopped and that led to
