基于SOP规程的大亚湾堆芯冷却监测系统改造

摘要

Core Cooling Monitor System (CCMS) is an important safety system for Daya Bay, and performs margin-to -saturation measurement and reactor vessel level monitoring functions. To improve the ability of accident disposal, EOP turns into SOP in Daya Bay NPP. It's the difficulty that the new requirements of interface and arithmetic for satisfying with the SOP. This paper presents the improvement of CCMS for SOP requirements.%大亚湾堆芯冷却监测系统（Core Cooling Monitoring System，简称CCMS）是大亚湾核电厂重要的安全级系统，用于完成堆芯温度测量与压力容器水位监测的功能。为提高核电厂应对事故的能力，大亚湾核电厂改造从事件导向法规程过渡到状态导向法规程，状态导向法规程对CCMS系统接口和算法提出了新的要求，这也是本次改造的难点。本文重点描述了为满足这些要求，CCMS系统所做的改进。
