| Title | Licensee-Identified Violation |
| Description | Technical Specification 3.5.A.3, Primary Containment Integrity requires that with one or more of the automatic containment isolation valves inoperable: maintain at least one isolation valve operable in each affected penetration that is open and within 4 hour4.62963e-5 days <br />0.00111 hours <br />6.613757e-6 weeks <br />1.522e-6 months <br />s: restore the inoperable valve(s) to operable status, isolate the affected penetration by use of at least one deactivated automatic valve secured in the isolation position, or isolate each affected penetration by use of at least one closed manual valve or blind flange. Contrary to this, on February 2, Exelon personnel did not identify that automatic containment isolation valve V-16-14(reactor water cleanup (RWCU) heat exchanger inlet isolation valve) was inoperable and take the required actions as stated above. This violation was of very low safety significance (Green) because the finding did not represent an actual open pathway in the physical integrity of the reactor containment because the redundant PCIV V-16-1 was operable during the time period when V-16-14 was inoperable. This issue is described in corrective action program condition report IR 875329. Exelons corrective actions included briefing operations personnel of this event and reinforcing proper technical rigor is applied when issues are identified |
