【摘要】 核电站风险监测系统(Risk Monitor)可对核电站的运行风险进行实时监测和预测,是概率安全评价(PSA)技术的高级应用之一。FDS团队广泛调研了国际现有核电站风险监测系统的研发现状,深入研究了风险监测系统涉及的各种关键算法并探索了相关实现技术,基于前期自主研发的大型集成概率安全分析软件RiskA发展了通用核电站风险监测系统RiskAngel,并以此为基础结合秦山三期重水堆核电站的安全特点和实际应用需求开发了秦山三期重水堆核电站风险监测器(TQRM)。本文总结了核电站风险监测系统的发展现状及趋势,对TQRM系统的设计思想、总体架构、主要功能、关键算法、技术特点及相关测试应用进行概要介绍。更多还原

【Abstract】 A risk monitor,an integrated risk analysis tool for real-time monitoring,was widely used in the management of nuclear power plants around the world.A risk monitor prototype system,named RiskAngel,has been developed by FDS Team,China,in which the fault tree analysis engine RiskA was integrated.Based on these,Third Qinshan nuclear power plant Risk Monitor(TQRM) has been developed considering the safety characteristics and the management process of Third Qinshan nuclear power plant.The status and development trend of risk monitor were given in this paper.An overview of the architecture and functions of TQRM was introduced.The key algorithms and technical features were also presented.更多还原
