乏燃料水池转运舱氦质谱检漏技术的应用

Application of helium mass spectrometry leak detection technology in spent fuel pit transfer cabin

乏燃料水池转运舱是核电站乏燃料水池的组成部分,用于存放燃料组件倒料设备和水。监测乏燃料水池转运舱的水的泄漏率,通过气体和水的泄漏率转换,分析和计算出氦气检漏的泄漏率范围,并建立检测区域模型,优化检测范围和流程,通过范围查找和精确查找的结合,快速和准确地找到泄漏位置,以为乏燃料水池的查漏工作提供经验。

The spent fuel pit transfer module is mainly apart of spent fuel pit of nuclear power plant,which is used to store fuel assembly materials and water.This paper outlines the monitoring of the leak rate of fluid water,predicts the leak rate range of helium gas leak detection through the conversion of gas and water leak rate,establishes the inspection area model,optimizes the inspection scope and process,finds the leak location quickly and accurately through the combination of range search and accurate search,and provides some experience for the leak detection of spent fuel pit.
