核电厂电气贯穿件设备延寿再鉴定方法研究

以秦山一期核电厂电气贯穿件（EPA）为实施对象，基于已有设备设计、制造、鉴定和实际运行数据，并结合国内外核电厂的设备鉴定、老化延寿管理等标准规范和最新研究成果，开展了核电厂设备延寿再鉴定方法研究，同时结合目前国内核电厂类似EPA等1E级核安全设备老化管理的现状，提出了设备老化管理建议。 

Study on Life Extension and Re-Qualification Method for Electrical Penetration Assembly of Nuclear Power Plants

This paper takes the electric penetration assembly(EPA) of Qinshan NPP as the research object, based on the existing EPA design, manufacturing, qualification and actual operation data, combined with domestic and foreign standards, specifications and latest research results of equipment qualification, aging and life extension management of NPPs, the re-qualification method of equipment life extension of NPPs is studied. Considering the current status of aging management of 1 E nuclear safety equipment such as EPA in domestic NPPs, this paper proposes the equipment aging management recommendations.
