摘　　要：核电厂防火一直都是核电厂必须考虑的关键性安全问题。主控室作为机组正常控制的中心,集中了操纵员所需的监控设备,一旦发生火灾,机组的安全将受到严重威胁。由于主控室的安全重要性,以及主控室里面有大量的点火源和可燃物,因此,主控室火灾风险分析是火灾PSA中不可或缺的重要部分。本文主要从火灾PSA的角度,对功率工况下方家山核电厂主控室火灾开展情景分析,定量计算主控室火灾导致的堆芯损伤频率,找出薄弱环节,给出风险见解。Fire prevention is always a key issue that nuclear power plant must consider.The main control room contains control and monitoring equipment needed by the operator so that the operator can control the main functions of the nuclear power plant from the same location.The main control room is the center of the normal control of the unit.If a fire occurs,the safety of the unit will be seriously threatened.Due to the safety importance of the main control room and the large number of ignition sources and combustibles in the main control room,the fire risk analysis of the main control room is an indispensable and important part of the fire PSA.The paper introduces the fire PSA scenario analysis of the main control room in Fangjiashan nuclear power plant,calculates the core damage frequency caused by the fire of main control room,identifies the weakness and gives the risk insight,from the perspective of the fire PSA.
