RiskA计算引擎在核电站概率安全评价中的应用
Application of calculation engine of RiskA to nuclear power plant’s probabilistic safety assessment
【摘要】 研究分析了R&R Workstation平台的计算引擎配置问题,实现了该平台下调用FDS团队自主研发的RiskA计算引擎。基于上述工作,采用真实核电站的概率安全评价模型,对RiskA计算引擎进行了正确性校核,并与CQUANT引擎进行了计算速度比较。测试表明正确实现了在PRAQUANT下对于RiskA计算引擎调用,RiskA的定性分析和定量计算结果正确,在计算速度上RiskA远快于CQUANT。
【Abstract】 PRAQUANT is one of the modules used for accident sequence quantification in R&R Workstation,a suite of probabilistic safety assessment software.And CQUANT is the quantification engine of PRAQUANT.RiskA is a fault tree quantification engine developed by FDS Team,which can be integrated into PRAQUANT as a third party quantification engine.The process of the integration was introduced in this paper,as well as the benchmark between RiskA and CQUANT.The results of benchmark showed that the algorithms adopted in RiskA are correct and efficient.
