一种基于守恒方程的反应堆故障诊断方法

A conservation-equation-based method to diagnose reactor components faults

介绍了一种直接利用守恒方程进行反应堆故障诊断的方法。该方法强化了利用控制体定性守恒方程通过定性推理确定故障源发控制体的能力,并且以产生式规则集来描述反应堆部件的故障模式和控制体内质量、动量、能量异常之间的关系,具有维护和使用的灵活性。最后以10 MW高温气冷实验堆的两个事故为例对该方法进行了例证。

This paper presents a method based on conservation equations to diagnose reac- tor components faults. This method improves the capability of qualitatively inferring the source of fault by mass, momentum and energy conservation in a control volume. It de- scribes the relationship between the fault pattern of nuclear reactor components and the abnormality of mass, momentum and energy in control volumes by production rules. It＇ s flexible for maintenance and use. Two accident scenarios in 10 MW high temperature gas cooled reactor （HTR-10） have been taken as examples to verify this method.
