| Title | Unacceptable Preconditioning of High Pressure Coolant Injection System Air-Operated Valve Prior to Stroke Time Test Measurement |
| Description | The inspectors identified a finding of very low safety significance with an associated non-cited violation of 10 CFR 50, Appendix B, Criterion V, Instructions, Procedures, and Drawings. The licensee failed to establish an adequate procedure to perform required stroke time testing for high pressure coolant injection turbine supply drain pot to main condenser drain line isolation valve E4100-F028. Specifically, the surveillance test procedure resulted in unacceptable preconditioning of the valve prior to the stroke time test measurement. The licensee entered this issue into its corrective action program for evaluation and initiated a corrective action to revise the test procedure. The finding was of more-than-minor significance since it was associated with the Procedure Quality attribute of the Barrier Integrity Cornerstone and adversely affected the cornerstone objective to provide reasonable assurance that physical design barriers protect the public from radionuclide releases caused by accidents or events. Because the preconditioning altered the as-found condition of the air-operated valve, the data collected through the performance of the surveillance test were not fully indicative of the true valve performance trend. Therefore, this performance deficiency had a direct effect on the licensees ability to trend as-found data for the purpose of assessing the reliability of the valve. The finding was a licensee performance deficiency of very low safety significance because it did not involve an actual open pathway in the physical integrity of the Auxiliary Building. The inspectors concluded that because the valve testing sequence that unacceptably preconditioned E4100-F028 had existed in the surveillance test procedure for greater than three years and no opportunity reasonably existed during that time to identify and correct it, this issue would not be reflective of current licensee performance and no cross-cutting aspect was identified. |
