摘　　要：基于保守的确定性失效裕度(CDFM)法,介绍某核电厂蒸汽发生器抗震易损度分析的过程和结果,讨论CDFM法的工程应用、各裕度因子的计算及高置信度低失效概率(HCLPF)值的计算。结果表明:采用CDFM法计算得到的蒸汽发生器的HCLPF值满足设计要求,并且有一定裕量。Based on conservative deterministic failure margin(CDFM)method,an introduction was given to the process and result of the seismic fragility analysis of the steam generator in a nuclear power plant,while disscussions were conducted on the engineering application of CDFM method and the calculation of each margin factor and high confidence of low probability of failure(HCLPF)value.Results show that by adopting CDFM method,the HCLPF value of the steam generator can satisfy the design requirements,which also has a margin.
