摘　　要：堆芯冷却监测系统(Core Cooling Monitoring System,简称CCMS)用于对压水堆堆芯冷却状态进行监测,属于安全级系统。北京广利核公司采用FirmSys安全级数字化仪控平台产品,对大亚湾核电站CCMS系统进行了数字化改造,以解决原系统可用性降低、堆芯冷却状态算法存在不足、记录功能较弱的问题,同时满足大亚湾核电站事故管理规程从事件导向规程(EOP)向状态导向规程(SOP)过渡的需要。改造后的1#机CCMS系统在2013年11月投入使用,运行稳定可靠。这是国内在役核电厂安全级数字化仪控系统的首次改造,也是国产核级安全级数字化仪控产品FirmSys在国内核电站安全级的首次应用。改造方案可供同类系统改造借鉴。The Core Cooling Monitoring System （CCMS ）,as a safety system, is used for the monitoring of the pressure vessel core!s cooling condition. China Techenergy Co. adopted the FirmSys safety digital instrumentation and control product,and modified the CCMS in Daya Bay nuclear power plant （NPP） . The products solve the problems such as the declining of the usability of the old system,the flaws of the algorithm of core cooling condition, and the poor recording functions. It can meet the need of procedure upgrade from Event Oriented Procedure （EOP） to State Oriented Procedure （SOP） . This is the first timeto modifythe safety digital instrumentation and control system of NPPin operationin China, andas well the first time to use FirmSysin safety system in chinses NPP. The solution could be a reference to the modification of the same kind systems.
