| Title | Failure to Perform Inservice Testing of High Pressure Coolant Injection and Reactor Core Isolation Cooling System Valves |
| Description | The inspectors identified a finding of very low safety significance with an associated non-cited violation of 10 CFR 50.55a. The licensee failed to perform required inservice testing of high pressure coolant injection and reactor core isolation cooling turbine supply drain pot to main condenser drain line isolation valves E4100-F029, E5150-F025, and E5150-F026. The licensee entered this issue into its corrective action program for evaluation, completed an immediate operability determination, and initiated a corrective action to revise applicable test procedures to incorporate inservice testing of the valves. The finding was of more-than-minor significance since it was associated with the Structures, Systems, and Components and Barrier Performance 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. Specifically, the licensees failure to perform required inservice testing had a direct effect on its ability to trend as-found performance data for the purpose of assessing the reliability of the three isolation valves, which are required by design to isolate seismically qualified portions of the piping systems from non-seismically qualified portions. 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 Reactor and Auxiliary Buildings. The inspectors concluded that because the engineering evaluation that excluded the valves from inservice testing was completed in 1999 and no recent opportunity reasonably existed to identify and correct the error, this issue would not be reflective of current licensee performance and no cross-cutting aspect was identified. |
