Research on the effect of uncertainty of earthquake hazard analysis on the nuclear power plant seismic margin assessment
Li Mi · Earthquake Engineering and Engineering Dynamics · 2014
The seismic margin assessment methodology is considered a necessary approach to assess nuclear plant safety to external events. To a large degree,the key parameters of seismic margin assessment rely on the seismic hazard analysis,which is greatly influenced by the uncertainty of probabilistic seismic hazard analysis. This paper mainly introduced the seismic margin assessment methodology,the selection of review level earthquake,the uncertainty of probabilistic seismic hazard analysis and its effects on seismic margin assessment. At last,some suggestion about how to deal with the uncertainties is provided.
