AP1000 PSA模型研究及模型格式转换程序开发

Study of AP1000 PSA Model and Development of Model Format Conversion Code

第三代核电技术AP1000引进中的概率安全评价（PSA）模型是用CAFTA程序建立的，而我院使用的是RiskSpectrum程序。在分析两个程序数据文件的基础上，开发CAFTA2RS转换程序，从CAFTA建立的PSA模型中提取相关的信息，修正其不符合RiskSpectrum程序的数据格式，将AANB和EQU等门类型转换为RS程序允许的门类型，并将长达数千页的大型故障树拆分成符合RS格式的4000多棵小故障树，实现CAFTA程序建立的PSA模型到RiskSpectrum程序的PSA模型之间的自动转换。

The probabilistic safety assessment （PSA） model of the third generation nuclear power technology （AP1000） is built with CAFTA code, while the RiskSpectrum code is used in our institute. Based on the analysis of the data files of these two codes, the conversion code CAFTA2RS is developed to abstract the information from the PSA model built with CAFTA, modify the data format inconsistent with RiskSpectrum, convert the gate type, such as AANB, EQU, etc., to the gate type consistent with RiskSpectrum and finally convert the PSA model from the format of CAFTA code to the format of RiskSpectrum code automatically.
