摘　　要：本文介绍了美国最新版ASCE 43-19《核设施构筑物、系统和设备的抗震设计标准》,梳理了基于风险指引和性能目标的核设施抗震设计方法;考虑到风险重要性,为不同的研究堆构筑物、系统和设备分配不同的抗震设计类别(即不同的设计基准地震动水平)和不同的设计性能限制(即不同的极限状态);对比了不同版本的ASCE 43-19和ASCE 43-05标准对抗震设计分类和确定设计基准地震的区别及影响。通过研究美国研究堆VTR和SHINE的抗震设计方法及美国核管会的审评实践,为我国研究堆确定合理的抗震设计输入提供参考。Introduced the latest version of ASCE 43-19“Seismic Design Standards for Nuclear Facility Structures,Systems,and Equipment”in the United States,and sorted out seismic design methods for nuclear facilities based on risk guidance and performance objectives;Considering the importance of risk,assign different seismic design categories(i.e.different design basis ground motion levels)and different design performance limits(i.e.different limit states)to different research reactor structures,systems and equipment;The differences and impacts of different versions of ASCE 43-19 and ASCE/43-05 standards on seismic design classification and determination of design basis earthquakes were compared.The seismic design methods of the U.S.research reactor VTR and SHINE and the review practice of the U.S.Nuclear Regulatory Commission are studied to provide reference for determining reasonable seismic design input of China’s research reactor.
