数字化核电机组过程仪表系统定期试验分析

Analysis of Periodic Test for Computerized Nuclear Power Plant Process Instrument System

在核电站整个寿期内,定期试验用于检查安全系统及安全相关系统与其设计安全功能准则的一致性。过程仪表系统是核电厂定期试验的重要内容,通过过程仪表系统执行核电机组的反应堆停堆、专设安全设施以及事故后监测等安全功能。运行人员需要制定系统对应的运行定期试验规程,从而保证核安全以及运行人员和设备的安全。对数字化核电机组过程仪表系统定期试验的范围和内容进行了全面分析,以确保过程仪表系统的定期试验的完整性和全面性。

In the nuclear power plant overall life,the periodic test is designed to examine the safety function of the safety or safety related system is consistent with its safety criteria Periodic test for process instrument system is an important part of the periodic test.Process instrument system is used for reactor trip system,engineered safety features actuation system and post accident monitoring system,etc.The operators have to design the periodic test procedure to ensure the safety of nuclear power plant,safety of the equipment and operators.This paper describes the design process of periodic test,and analyses the periodic test for process instrument system.
