Abstract: Qualification of equipment is an important guarantee for nuclear power plants. Introduction was made to the containment electric penetration assembly in nuclear power station. This paper studied the relevant standards of the electrical penetration assembly, compared to the identification requirements of the electrical penetration assembly in different standards about severe accidents, and combined with the concrete practice of the three generations of nuclear power plants such as AP1000, EPR, Hua-long No. 1 etcthree generations nuclear power station concrete practice. The qualification and implementation under the condition of severe accident of electrical penetrating parts were clarified to provide references for the qualification of other equipment in nuclear power plant.
Key words: nuclear power plant; electric penetration assembly; severe accidents; qualification of equipment
