Development of Risk Assessment Method for Fires Caused by Earthquake (VI)

摘要

A concept and calculation formula is presented for the conditional occurrence probability of fire in case of earthquake. The median values of precursory phenomenon capacity for important components of nuclear power plants are calculated by the proposed formula and results are listed up. A method to quantify risk due to earthquake-induced fire is presented. The procedure of risk assessment for fires caused by Earthquake is explained with a flow chart. An analysis framework for the earthquake-induced fire PSA, which is now being developed, is explained.
