从某核电站运行情况分析今后辐射监测系统设计的改进

Analysis of design improvement on radiation monitoring system A operation condition of nuclear power plant

以巴基斯坦恰希玛核电站一期辐射监测系统近两年测量数据为依据,对该核电站辐射监测仪表的运行工况进行分析。结果表明:绝大部分辐射监测仪表处于正常运行状态,部分仪表偶尔会出现异常数据。根据工艺过程特点分析了辐射监测仪表出现异常数据的可能性原因,并对辐射监测系统设计的改进提出了建议,供今后核电站辐射监测系统设计参考。

According to the radiation monitoring data in adjacent two years＇ of Chashrna Nuclear Power Plant, the operating condition of radiation monitoring instrument is analyzed in the paper. The result shows that the radiation monitoring instruments were majority in the normal operating state and occasion- ally given some abnormity data. The possible reason for the abnormity data is analyzed according to the process characteristic. The suggestion for design improvement of the radiation monitoring system is given in the paper. It is referenced for the radiation monitoring system design in the future.
