On 11th March, 2011, most sever nuclear power plant accidents in the history have been occurred at the Fukushima site due to the massive earthquake and subsequent large Tsunami. As the results of the loss
of all AC power or station blackout, the reactor cores have melted down in Unit 1 through Unit 3. In the present study, the core damage probabilities for Units 1 through 3 have been evaluated by event tree analyses under the condition of the loss of all AC power or station blackout. The core damage probability at72hours (3 days) after the Tsunami are obtained as 0.73(Unit 1), 0.25(Unit 1) and 0.13 (Unit 3). All three units damaged core after 7days. The discussions are made based on the analysis results and cosider the meaning of Fukushima power reactor accident. |
