秦山第二核电厂堆芯功率分布测量试验使用RIC系统的4个移动微型裂变电离室入堆进行测量。由于制造公差以及探测器辐照历史不同等原因,4个微型裂变电离室的探测效率各不相同。为了计算探测器之间探测效率的校刻因子,一般使用参考通道校刻法和交叉通道互校法。本文给出了几种校刻因子计算方法,并将所计算的校刻因子结果与法国CARIN程序校刻因子的计算结果进行了对比,供科技人员参考。

Four detectors of RIC system are used to measure the flux map in the reactor.The efficiencies of the detectors are different because of the fabricate tolerance and the different radiation history.In order to calibrate the efficiencies of the detectors,reference channel test and cross channel test are used.In the paper,there are some methods to calculate the efficiencies.And the results were compared with CARIN software,which is provided by AREVA.
