基于浮动报警阈值的燃料元件包壳破损监测方法的分析与研究

针对燃料元件包壳破损监测报警阈值设置为固定阈值的不足,利用数理统计与概率分析理论提出浮动报警阈值的概念,对浮动报警阈值的设置进行了初步探讨。分析表明,在燃料元件包壳破损监测中,浮动报警阈值可较真实、快速地判定燃料元件包壳破损情况并及时报警。

Analysis and Research on Fuel Cladding Failure Monitoring Based on Floating Alarm Threshold

Considering the shortcomings of traditional fixed threshold set as alarm threshold for fuel cladding failure monitoring, this paper puts forward the concept of floating alarm threshold and carries on a preliminary study on floating alarm threshold setting, based on mathematical statistical and probabilistic analysis method. The study shows that during fuel cladding failure monitoring, floating alarm threshold can monitor the condition of fuel cladding failure in a more accurate way and at a higher speed and alarm in time.
