Content:
of inservice testing, environmental monitoring and management activities, the incorporation of cable-related operating experience, periodic formal cable DG-1240, Page 9 condition assessment review and trending, and problem identification and corrective action, to constitute an effective cable condition monitoring program: a. Select cables to be monitored. b. Develop database for monitored cables. c. Characterize and monitor service environments. d. Identify stressors and expected aging mechanisms. e. Select condition monitoring techniques suitable to monitored cables. f. Establish baseline condition of monitored cables. g. Identify cable characteristics and aging effects being monitored by each selected condition monitoring technique. h. Perform test and inspection activities for periodic condition monitoring of cables. i. Periodically review and incorporate plant and industry experience. j. Periodically review, assess, and trend the condition of monitored cables. k. Identify degraded conditions and take prompt corrective actions. 2. The NRC staff considers the use of appropriately selected combinations of the typical cable condition monitoring techniques, such as those discussed in section B above, within the framework of a comprehensive cable condition monitoring program to be an acceptable method for satisfying the Commission’s regulations with respect to condition or performance monitoring of electrical cables installed in nuclear power plants. The condition monitoring techniques selected should be based on plant- specific design, installation, and operating conditions and operating experience related to the cables used in nuclear plants. D. IMPLEMENTATION The purpose of this section is to provide information to applicants and licensees regarding the NRC’s plans for using this draft regulatory guide. The NRC does not intend or approve any imposition or backfit in connection with its issuance. This guide is intended to provide a compilation of techniques
