Abstract

For more than 20 years the NRC has sponsored research studying the aging degradation, condition monitoring and environmental qualification, and testing practices for electric cables and cable accessories used in nuclear power plants. The essential elements for an effective cable condition monitoring program presented in this report are based upon the results of the NRC’s electric cable and equipment research programs, industry guidance and standards, and the experience and observations of others who have studied or conducted electric cable condition monitoring and qualification testing. The program methodology presented herein provides guidance on the selection of cables to be included in the program, characterization and monitoring of cable operating environments and stressors, selection of the most effective and practical condition monitoring techniques, documentation and review of cable condition monitoring testing and inspection results, and the periodic review and assessment of cable condition and operating environments.
