对FDS团队研发的国产PSA软件RiskA进行了大量系统性的测试,采用完整的核电站真实系统模型,分别用RiskA和国际同类流行软件如Risk Spectrum进行了故障树的定性及定量分析,测试结果表明RiskA与国际同类软件相比,结果正确、模型可靠、算法精确。而Risk Spectrum在测试过程中暴露出了一些问题,如分析中采用阶数截断时单个最小割集的定量计算不正确等,对该问题进行了理论证明及初步的原因分析。
A systematic and systematic test of RiskA, a domestic PSA software developed by FDS team, is carried out. The complete system model of nuclear power plant is used to conduct qualitative and quantitative analysis of the fault tree with RiskA and international similar popular software such as Risk Spectrum. The test results show that RiskA Compared with the international similar software, the result is correct, the model is reliable and the algorithm is accurate. However, Risk Spectrum revealed some problems in the testing process. For example, the quantitative calculation of a single minimum cut set when the order truncation is used in the analysis is not correct. Theoretical proof and preliminary analysis of the cause are given.
