摘要
本文首先简要介绍地震概率安全评价（SPSA）定量化方法论，其次基于CAP1400抗震裕度评价（SMA）k$型建立简化地震PSA模型，并基于蒙特卡罗（MC）方法对CAP1400简化地震PSA模型进行了定量化分析，得到了地震导致堆芯损伤频率（CDF）均值。最后根据该结果进一步得到用于CAP1400设备筛选分析的筛选值，并初步判断对电厂地震风险贡献较大的构筑物和设备。
The methodology on quantification of Seismic Probabilistic Safety Analysis （SPSA） is introduced in this paper. Then a simplified SPSA model is developed based on the CAP1400 Seismic Margin Analysis model. With Monte Carlo （MC） method, the simplified SPSA model is quantified and the mean value of seismic-induced core damage frequency （SCDF） is obtained. Finally, the selection of screening level is discussed according to the CDF mean value. In addition, a list of structures and components which have significant contributions to the SCDF is obtained as a part of the output of the SPSA quantitative process.
