舰用电气设备在核电环境中的质量鉴定方法研究OA

Qualification of marine electrical equipment in nuclear environments is a critical technical link for ensuring nuclear safety.The fundamental methods for nuclear equipment qualification,including type testing,service experience,and analysis methods are systematically reviewed,and the technical requirements for K1,K2,and K3 qualification procedures are elaborated.By comparing the differences between marine and nuclear environments,supplementary qualification test items required for applying marine electrical equipment in nuclear settings are proposed,such as thermal aging tests,operational aging tests,seismic tests,and shock tests.The test results indicate that,in addition to meeting the environmental requirements of national military standards,marine electrical equipment must undergo nuclear-specific aging tests and seismic qualification to ensure functional reliability in different zones inside and outside the nuclear power plant containment.The results provide a technical reference for the nuclear-grade qualification of marine electrical equipment and holds significant importance for ensuring the safe operation of shipboard nuclear power systems.
