核电厂取样型液态流出物监测仪检定

Calibration of Sampling Liquid Effluent Monitor in Nuclear Power Plant

针对核电厂取样型液态流出物监测仪的探测器在核电厂现场无法进行检定的问题展开讨论,提供了代表点法、液体源法两种现场检定思路,并针对福清核电1-4号机组使用的流出物监测仪,给出具体的现场检定活动开展方法和具体步骤,并对检定结果的不确定度进行了评定,为同类型流出物监测仪检定工作提供了一种思路。

In view of the problem that the detector of the sampling liquid effluent monitor of nuclear power plant can not be verified in the field of nuclear power plant,two kinds of on-thespot verification ideas,representative point method and liquid source method,are provided.In view of the effluent monitor used in Fuqing NPP unit 1-4,the specific on-the-spot verification methods and specific steps are given,and the uncertainty of the verification results is improved The evaluation provides a way of thinking for the verification of the same type of effluent monitor.
