Design of Core Cooling Monitoring System Based on SOP

National Key Laboratory of Reactor System Design Technology, Nuclear Power Institute of China, Chengdu, 610041, China

摘要: 在岭澳核电站二期工程中首次采用状态导向规程(SOP)。根据该规程的要求,堆芯冷却监测系统(CCMS)需要完成SOP下6大状态功能中的2个监测任务,即一回路水装量和一回路压力温度的监测。由反应堆压力容器水位来反映水装量,用最低过冷裕度(ΔTsat)来反映一回路的压力和温度。为了完成这些监测任务,从一次仪表、数据处理到信息显示相对于事件导向规程(EOP)下的设计都有重大的不同,本文主要从系统设计的角度对其进行描述。

Abstract: Ling’ao phase II nuclear power project is the first SOP adopted plant in China.According to the requirement of this procedure,Core Cooling Monitoring System（CCMS） shall perform two of six status function monitoring tasks of SOP,including primary loop coolant inventory,pressure and temperature.Inventory is monitored by reactor vessel level and the rest are monitored by saturation margin.To fulfill these tasks,the system design,including sensors,data processing and information display,is significantly different from EOP design.This paper gives a generally description from the system design aspect.
