A Survey of Cable Ageing Management and Condition Monitoring in Nuclear Power Plants

Cable is one of the major nuclear power plant components that are directly related to safety, so that life assessment of the cable system is an important issue as one of international nuclear safety concerns. In general, cables installed in nuclear power plants have been regarded as maintenance-free component. However, for the long term operation, maintenance activities for cables important to safety should be done appropriately to ensure their capability for the required function This paper is summarized the findings from a review of published documents dealing with research on ageing management of safety-related electric cables used in nuclear power plants. Significant research in this area has been performed in several countries and international research projects
