摘要
本文基于运行核电厂主蒸汽管道泄漏率测量中存在的异常报警现象,提出了一种新的测量方法.通过量化计算公式基础、源项修改,结合MC方法,按照不同工况下的源项组成进行探测效率的模拟计算,最终得出主蒸汽管道泄漏率值.该方法研究可为泄漏率监测仪算法模型改进提供理论指导与设计输入.
In this paper,a new measurement method is proposed based on the abnormal alarm phenomenon existing in the leakage rate measurement of the main steam pipeline of the operating nuclear power plant.By quantifying the calculation formula basis,modifying the source item,combined with the.MC method,the simulation calculation of the detection efficiency is carried out according to the composition of the source item under different working conditions,and the leakage rate value of the main steam pipeline is finally obtained.This method study can provide theoretical guidance and design input for the improvement of the algorithm model of the leak rate monitor.
