摘要
本文针对无法实现对反应堆主冷却剂中关键核素实时监测的现状,通过分析影响核素快速测量的各种因素,提出了基于核素衰变特性的改进关键核素法。实验结果表明,利用便携式γ谱仪,通过分组分段测量,能提高短寿命裂变核素的测量速度和精度。
According to the present situation that key nuclides in primary coolant can not be monitored in real-time ,various influencing factors of rapidly measuring nuclides were analyzed ,and the improved key nuclide method was proposed based on the decay prop-erties of nuclides .T he results indicate that the speed and accuracy of measuring short-lived fission nuclides are improved by packet-segmentation measurement with portable γspectrometer .
