摘　　要：抗震裕度评价(SMA)是核电厂地震安全评价的方法之一,而计算构筑物、系统和部件(SSC)的高置信度低概率失效(HCLPF)值是开展抗震裕度评价的重要内容之一。本文介绍了HCLPF值的定义和计算HCLPF值的保守的确定论失效裕度(CDFM)方法。结合秦山核电厂抗震裕度评价,以应急柴油发电机组和主控制楼为例说明了CDFM方法在核电厂SMA中的应用。通过计算得到了大部分SSC的HCLPF值,为秦山核电厂SMA工作的顺利开展奠定了基础。The seismic margin assessment（SMA）is one of the nuclear power plant seismic safety evaluation methods.The calculation of high confidence for low probability of failure（HCLPF）value for the structure,system and components（SSC）is one of the important contents of SMA.The definition for HCLPF value and the conservative deterministic failure margin（CDFM）method which was used to calculate HCLPF value were introduced in this paper.The emergency diesel generator set and the main control building of Qinshan Nuclear Power Plant were taken as examples.Their HCLPF values were analyzed with CDFM method.Most of the HCLPF values of SSCs were obtained by this method to provide the foundation on which the SMA of Qinshan Nuclear Power Plant can be developed.
