| Title | Inadequate Abnormal Operating Procedure for Internal Flood Mitigation Strategy |
| Description | The inspectors identified a Green NCV of Technical Specification (TS) 6.8.1,Procedures and Programs, for the licensees failure to establish an adequate procedure associated with Abnormal Operating Procedure (AOP) M.08, Internal Flooding. Specifically, internal flooding due to a fire protection header pipe break into the shutdown board rooms did not prompt entry into AOP-M.08. Failure to properly establish an adequate abnormal operating procedure (AOP) to mitigate the impact of an internal flood in the shutdown board room was a performance deficiency. Specifically, the failure to properly establish an adequate AOP to mitigate the impact of an internal flood in the shutdown board rooms, could have potentially compromised the sites ability to safely shutdown the plant in the event of a pipe leak or rupture in that area. The licensee entered this issue into the CAP as PER 639295. The performance deficiency was determined to be more than minor because it was associated with the procedure quality attribute of the mitigating systems cornerstone and adversely affected the cornerstone objective to ensure the availability, reliability, and capability of systems that respond to initiating events to prevent undesirable consequences. The inspectors performed the significance determination using NRC Inspection Manual Chapter 0609, Significance Determination Process. Because the finding affected the Mitigating Systems Cornerstone while the plant was at power, Attachment 4, Phase 1 - Initial Screening and Characterization of Findings, evaluates the finding using Appendix A. Using Appendix A, Exhibit 2, Mitigating Systems Screening Questions, the finding was determined to be of very low safety significance because it was not a design or qualification issue and was confirmed not to result in a loss of operability or functionality; did not represent an actual loss of safety function of the system or train; and did not result in the loss of one or more trains of non-technical specification equipment. The finding was determined to have a cross-cutting aspect in the CAP component of the Problem Identification and Resolution area P.1(c) since the licensee failed to thoroughly evaluate the issues identified in PER 344249 such that the resolution addressed the cause and extent of condition. |
