| Title | Failure to Translate Seismic Design Requirements into Applicable Procedures |
| Description | The inspectors identified a Green finding and an associated non-citied violatio
of 10 CFR Part 50, Appendix B, Criterion III, Design Control, for the failure to adequatel translate seismic requirements from a design calculation into applicable procedures Specifically the licensee failed to incorporate the seismic requirements for th division III 4.16 Kilovolt (KV) switchgear as described in calculation IPQ0391, Seismi Qualification of 480V ABB Unit Sub Switchgears, Div I & II Westinghouse Switchgear and Div III GE 4.16 KV Switchgears, into procedure CPS 1014.11, 6900/4160/480 Switchgear/Circuit Breaker Operability Program, resulting in the licensee incorrectl declaring division III switchgear operable when in a seismically unanalyzed condition The licensee entered this issue into their CAP as AR 2386676 and restored the switchgear to an operable condition by removing the breaker completely. The licensee also revised the procedure to incorporate the design requirements described in the seismic design calculation for the division III switchgear. The inspectors determined that the failure to adequately incorporate the seismic requirements of the design calculation into the applicable procedure was a performance deficiency. The finding is more than minor in accordance with IMC 0612, "Power Reactor Inspection Reports," Appendix B, "Issue Screening," dated September 7, 2012 because, because it is associated with the design control attribute of the Mitigating Systems cornerstone and adversely affected the cornerstone objective of ensuring the availability, reliability, and capability of systems that respond to initiating events to prevent undesirable consequences. Based on a detailed risk evaluation, the inspectors determined that the finding was of very low safety significance. The inspectors determined that there was no cross-cutting aspect associated with this finding because the cause of the performance deficiency occurred more than fifteen years ago, and was not representative of current licensee performance. |
