摘要
对我国已经投入运行的5个核电站发生的72起非计划停机停堆事件进行了分类。重点分析了核电站仪表控制(以下简称仪控)系统故障和人因失效导致的非计划停机停堆事件的原因,分析结果表明:虚假信号、控制部件故障、参数设定不当和调节阀故障等因素是导致仪控设备故障的主要原因。在此基础上,提出了相应的预防措施。
72 scram events in the nuclear power stations in China are classified in this paper, with focus on the analysis of the scram events caused by I＆C faults and human failures.The result demonstrates that the phantom signal, control unit malfunction, parameter unmerited and control valve malfunction are the first cause for instrument control equipment failure. Preventive solutions are proposed.
