研究堆辐射监测系统故障检修方法

Maintenance for Radioactivity Detecting System of Research Reactor

介绍了包括16Nγ监测、元件破损监测、主冷却器破损监测、工艺间γ监测、低放惰性气体β监测在内的辐射监测系统的几种探测模式及其原理。通过分析探测器故障和处理组件故障这两类故障的原因,发现辐射监测系统在运行中故障的产生分布有一定的规律,总结出了典型的故障检修方法,为同类辐射监测系统的检修维护以及设计提供借鉴。

This paper introduces the several detection modes and principles of Radioactivity Detecting System,including 16NγDetecting System,fuel assembly fail Detecting System,Main Heat Exchanger Detecting System,EnvironmentγDetecting System and Inert GasβDetecting System.Based on the reason of i.e.component communication failure and detector failure of the Radioactivity Detecting System,it is found that the system has certain regularity in the occurrence and distribution of running faults.Through the regularity,summarized the typical corrective maintenance to provide reference for the maintenance of the system.
