| Title | Failure to Restore Nuclear Service Cooling Water Manual Valves to their Required Locked-Open Position |
| Description | The NRC identified an NCV of TS 5.4.1.a, Procedures for the licensees failure to properly implement administrative control procedure 10019-C, Control of Safety Related Locked Valves, version 15.3. As a result, two nuclear service cooling water (NSCW) manual valves were not in their required locked-open position. The licensee restored the valves to their locked-open position. The violation was entered into the licensees corrective action program as condition report 880824. The performance deficiency was more than minor because it was associated with the Equipment Performance and Configuration Control attributes of the Mitigating Systems cornerstone and adversely affected the cornerstone objective in that the throttled position of the valves reduced the cooling capability of the associated mitigating systems heat exchangers and the unsecured condition reduced the safety-related locked valve programs objective to control and maintain the configuration of valves required to be in a specified position. The finding screened as Green because the flow rates associated with the valves throttled position were determined to be sufficient to maintain the supported systems operability. The inspectors determined the finding had a cross-cutting aspect of documentation in the human performance area because the organization provided inaccurate documentation of the valves manipulation log sheet. |
