Abstract

Earthquake is one of the main external risk factors for nuclear power. Especially after the March 11 earthquake in Japan, the Fukushima nuclear power accident has attracted worldwide attention. The seismic margin of existing nuclear facilities in all countries has been evaluated. However, the seismic margin assessment is mainly aimed at the situation beyond the design basis. For some existing nuclear facilities, there are changes in the seismic fortification criterion. At this time, it is necessary to conduct seismic appraisal. For the seismic appraisal of civil buildings, countries all over the world have formed relatively perfect technical standards, but there is no mature and general method for the seismic appraisal of existing nuclear facilities. When seismic identification of existing nuclear facilities is carried out, simple calculations based solely on the original design method are unreasonable. There is a need to propose a reasonable specialized method for seismic identification. Through the seismic evaluation of an existing nuclear facility, this paper puts forward the key technical problems to be considered in the research of seismic evaluation method of existing nuclear facilities. It provides a reference for the establishment of seismic evaluation method of existing nuclear facilities.
