Influence Analysis of the Halogen Cables Used in the Safety Related Circuits of AP1000 Nuclear Power Plant

摘要

The nuclear cable development is to non-halogen. However, due to the limitation of the non-halogen material performance and the excellent performance of halogenated materials, some halogen cables are still used in some area, equipment or systems in the nuclear power plant. This paper is to card the requirements of the halogen materials required in the nuclear safety rules and regulations in different countries. And this article takes an actual sample that AP1000 used halogen cables in some circuits and equipment. By analysis of the influence of adopting halogen cables in AP1000 Nuclear Power Plants, it is finally confirmed that some halogen cables can be used.
