Electromagnetic compatibility analysis and research on reactor electrical penetration assemblies

Reactor electrical penetration assemblies are essential components of nuclear reactor containments, enabling secure cable penetration and connection while serving as a critical barrier to prevent the release of radioactive materials, which is directly linked to reactor safety. Despite their importance, existing standards for electromagnetic compatibility (EMC) testing present ambiguities, limiting the accuracy and effectiveness of testing practices. To address challenges, this study provides a comprehensive evaluation, combining review standards with detailed analysis of limitations. A practical testing methodology is proposed, specifically tailored to the operational environmental demands of reactor systems. Experimental validation conducted on actual prototypes demonstrates that the proposed approach not only meets but exceeds existing EMC requirements. The findings of this work offer both theoretical and practical value, providing guidance for engineers and standardization bodies to refine testing procedures, inform regulatory frameworks, and ultimately enhance the safety and reliability of nuclear reactor electrical systems.
