摘要
在钠冷快堆中,蒸汽发生器泄漏是重要的检测参数。钠中气泡噪声探测器可以通过检测蒸汽发生器内气体体积份额的变化,来判断蒸汽发生器内部是否有泄漏发生。本文从需求概述、结构组成、信号处理、噪声信号分析、流量计算方法等几个方面分别入手,简述钠中气泡探测器的探测原理,以完整介绍钠中气泡噪声探测器对于泄漏检测的实现。
In the sodium-cooled fast reactor,the steam generator leak is an important detection parameter.The bubble noise detector in sodium can determine whether a leak has occurred inside the steam generator by detecting the change in the gas volume share in the steam generator.This paper includes following aspect of requirement overview,structure composition,signal processing,noise signal analysis,flow calculation method,etc.and briefly describes the detection principle of bubble detector in sodium,in order to completely introduce the sodium bubble noise detector for leakage detection.
