Abstract：On the seismic safety assessment (SSA) of the nuclear power plant site,in order to comply with and rather understand the code and policy related to the utility of the Probability Safety Analysis (PSA) in nuclear safety field, based on the spatial and temporal distribution of the seismic and geological events, the sampling representative and frequency, time series analysis and basic assumption herein are discussed. It is believed that these conditions yielded a limitation in the utility of PSA to SSA and exhibit that the probability is a relative invariable value.Therefore, imaginabale developments are to combine geodynamics and regard the probability as a random variable.
