摘要
介绍了船用堆燃料元件破损监测中较常用的两种方法。通过分析其缺陷,提出了用NaI多道脉冲幅度分析系统测量特征核素(131I、137Cs)的方法,有效避免了监测中的干扰因素的影响,降低了定量监测中的误报率,提高了燃料元件破损监测的效率和置信度。
Two methods of fuel element rupture detection are introduced in this paper. By analyzing their limitations, we put forward a new method by detecting the characteristic nuclides of ^131Ⅰ and ^137Cs with NaI detector and multi-channel pulse amplitude analyzer. It can reduce and eliminate the affecting factors, enhance the efficiency and precision of detecting.
