Abstract: There have been few Probabilistic Safety Assessments (PSAs) for a whole low power and shutdown (LPSD) period since the difficulties and the cost for these assessments are considerable when compared with those for a normal operation period. The frequent changes in system configurations and the reactor coolant system (RCS) states make it difficult to estimate a risk for the LPSD period.
