摘　　要：风险指引型缓解系统性能指标(MSPI)作为美国核管理委员会(NRC)核安全监管体系中的重要指标,是反应堆监管大纲中缓解系统的重要要素指标。MSPI可以从风险管理的角度体现系统和设备的不可用度和不可靠度以及系统部件性能限值,为核电厂设备管理提供更科学的依据,评价指标更为科学合理。近年来,中国核电引入了包括MSPI指标在内的一系列的设备性能管理体系,助力企业设备可靠性管理水平提升。本文介绍了MSPI指标的定义和计算方法以及在方家山核电厂的应用,MSPI的应用为核电厂的风险指引型设备管理和维修管理提供更科学依据。The mitigation system performance index(MSPI),as an important indicator in the NRC nuclear safety regulatory system,is an important mitigation system index in the reactor regulatory program.MSPI can reflect the unavailability and unreliability of systems and equipment,and the limitations of system components from the perspective of risk management,providing a more scientific basis for equipment management of nuclear power plant and more scientific evaluation indicators.In recent years,CNNP has introduced a series of equipment performance management systems,including MSPI,to help improve equipment reliability management.The paper introduced the definition and calculation methods of MSPI,and applications in Fangjiashan nuclear power plant.The application of MSPI provides a more scientific basis for the risk-informed equipment management and maintenance management of nuclear power plant.
