Attachment LR-N07-0316 REQUEST FOR ADDITIONAL INFORMATION REGARDING NRC GENERIC LETTER 2007-01 SALEM NUCLEAR GENERATING STATION, UNIT NOS. 1 AND 2 DOCKET NOS. 50-272 AND 50-311 AND HOPE CREEK GENERATING STATION DOCKET NO. 50-354 NRC Original Request (1)
Provide a history of inaccessible or underground power cable failures for all cables that are within the scope of 10 CFR 50.65 (the Maintenance Rule) and for all voltage levels.
Indicate the type, manufacturer, date of failure, type of service, voltage class, years of service, and the root causes for the failure.
Original Response For Both Salem and Hope Creek A review has been completed and no history of failures of inaccessible or underground power cables that are within the scope of 10 CFR 50.65, "Requirements for monitoring the effectiveness of maintenance at nuclear power plants," have been identified. This review examined the plant corrective action program, Maintenance Rule database, maintenance records, interviews with personnel, and a review of the circuit and raceway schedules to identify power cable failures. The scope of the review included alternating current power distribution cables with voltages from 480 VAC to 13,800 VAC. This represents our best effort in that data of this nature was not necessarily recorded in a means that was conducive to identifying cable failures.
RAI PSEG is requested to confirm that its review included the history of cable failures that occurred prior to July 10, 1996.
Additional Information Response for both Salem and Hope Creek The Salem and Hope Creek review of cable failures included those that may have occurred prior to July 10, 1996. The searches for power cable failures were performed using the Salem/Hope Creek Document Control and Records Management System database (DCRMS);
the cable and raceway database (Genesis); and PSEG nuclear work management system (SAP). Some of the logic in the search included looking for power cables that have been spliced, repaired, or replaced over the life of the plant, since these types of events are often associated with a cable failure. The records in Genesis originated from the former cable and raceway database, EE580, used during plant construction and startup. These records have 1
Attachment LR-N07-0316 been maintained using Genesis since that time. Documents in DCRMS provide references to rolls and frames on microfiche for records not stored in electronic format. Therefore, a review of the history of cable failures was not limited to July 10, 1996, but actually included records dating back to the era during the construction of both plants.
