摘要 本文介绍了国产化核级金属石墨密封垫片的密封原理和技术概况,通过对稳压器及蒸汽发生器相关密封垫片国产化替代的核安全审查,提出应从标准及规范符合性、设备鉴定、失效分析及跟踪检查措施等方面进行全面的核安全审查,以期对后续的国产化设备替代核安全审查提供借鉴。 This paper introduces the sealing principle and technical situation of domestic nuclear grade metal graphite sealing gasket. Through the nuclear safety review of the replacement of manhole and hand hole sealing gaskets for the regulator and steam generator,It is suggested that a comprehensive nuclear safety review should be carried out from the aspects of standard and specification conformance, equipment appraisal, failure analysis and follow-up inspection measures,In order to provide reference for the follow-up nuclear safety review of domestication equipment replacement.
