Abstract: In the light of the seismic safety requirement of nuclear power plant siting and complexity of earthquake hazards, the hybrid probabilistic method, seismotectonic method and historic earthquake method are used to determine the design basis ground motions. Of the three methods, the historic earthquake method can also gives a maximum value. In this paper, we have enumerated a relation of special earthquake intensity attenuation and the intensity anomaly to show that a recurrence probability of special historic earthquake condition should be considered in nuclear power plant siting, and that historic earthquake method may also result in a maximum value.

Key words: Nuclear power plant siting, Historic erathquake, Seismic intensity
