核电厂1E级安全壳内电动机鉴定试验相关问题的探讨

Discussion on Qulification Test of Class 1E Motor Inside Containment for Nuclear Power Plants

核电厂1E级安全壳内用电动机作为在正常工况下和设计基准事件期间及之后向核电厂安全系统设备提供动力的重要设备之一,必须按照相关的标准制定鉴定大纲和程序,进行鉴定试验。对1E级安全壳内电动机的鉴定过程和鉴定文件进行审查是核安全设备审查的重要内容之一。本文结合实际审评经验,探讨了电动机的加速热老化试验和LOCA试验中相关问题,提出了审评者的观点。

In nuclear power plant,class 1E motor inside containment is a kind of important equipment which is necessary for safety systems to provide power to safety systems in normal condition,during and post design basis events.So the class 1E motor inside containment must be qualified according to the qualification plan and procedure which is in conformity with the requirements in the relevant standards.The review for qualification of class 1E motor inside containment is an important aspect of nuclear safety equipment review.Combining with the review practical experience,this article discusse aging test and LOCA test of class 1E motor inside containment for nuclear power plants,then propose reviewers opinions.
