核电厂电仪设备的服役环境监测

Service Environments Monitoring of E&IC Equipment during Nuclear Power Plant Operation

电仪设备的老化与其服役环境密切相关,设备的服役环境参数(如温度、辐射和湿度等)决定着设备及部件的老化速率,影响着设备的寿命和可靠性。本文就核电厂安全重要电仪设备环境监测的通用要求和监测流程,监测参数和监测仪表,监测位置和监测频度等内容进行了论述,可为核电厂电仪设备老化管理、故障根本原因分析、运行许可证延续等所需的电仪设备的服役环境参数获取提供支持和指导。

The aging of Electrical and I&C equipment is significant affected by their service environments.Equipment environmental parameters(such as temperature,radiation and humidity)govern the rate of aging degradation and affect the useful life and reliability of the equipment.This paper gives the general requirements,monitoring process,environmental parameters to be moniotred,instruments can be used,monitoring locations and monitoring cycle for environmental monitoring of E&IC equipment important to safety,which can provide guidance and support for obtaining service environmental parameters of E&IC equipment required for aging management of E&IC equipment,failure root cause analysis,operating license renewal,etc.
