核动力反应堆燃料元件破损监测分析是核反应堆安全极为重要的监测方法之一。为了对监测一回路水中预定的典型裂变产物放射性核素含量变化的仪器进行校准,本课题将利用LaBr3:Ce闪烁探测器建立一套谱仪测量系统,用放射性核素标准溶液制备成模拟源对测量系统进行效率校准,用 Nuclear power reactor fuel element damage monitoring and analysis is one of the most important monitoring methods of nuclear reactor safety. In order to calibrate the instrument for monitoring the change of radionuclide content of a predetermined fission product in the primary loop, a spectrometer measuring system will be set up using the LaBr3: Ce scintillation detector and the source of calibration will be prepared using a radionuclide standard solution Measurement system for efficiency calibration, use
