英文摘要
In the seismic PSA of nuclear facilities, seismic fragilities of equipment and systems are to be evaluated. However, the fragilities involve uncertainties since the seismically-induced failure mechanism is not sufficiently known and a failure event is rare. In the present study, a new methodology for quantifying the common mode failure caused by external events and for reducing fragility uncertainty using very limited information. The information criterion is selected as the index for the uncertainty. It has been found that the present work is useful for the risk assessment and management of rare earthquake hazard.
