Abstract: The reactor electrical penetration assembly is installed on the nuclear reactor containment vessel, serving as a connection channel for various cables while functioning as part of the containment structure to form a barrier against radioactive material leakage, thereby ensuring the integrity of the pressure boundary. Based on an analysis of domestic and international electromagnetic compatibility(EMC) standards related to electrical penetration assembly, combined with EMC research from relevant fields such as power cables and nuclear power assembly, this study comprehensively considered the differences between various standards and evaluated the applicability of practical test items. A feasible test technical plan was developed and experimentally validated. This solution takes into account the specific operating conditions and environmental factors of the reactor environment, thereby enhancing the reliability and safety of electrical penetration assembly in nuclear reactor applications.
Key words: nuclear reactor; electrical penetration assembly; electromagnetic compatibility(EMC); cable; test technical plan
