| Title | Licensee-Identified Violation |
| Description | Technical Specification 3.6.4 requires each containment isolation valve be Operable or, Either restore the valve to operable status or isolate the affected penetration within 4 hours4.62963e-5 days <br />0.00111 hours <br />6.613757e-6 weeks <br />1.522e-6 months <br /> by use of at least one closed manual valve. Contrary to the above, on June 1, 2008, secondary system containment isolation valve CV-3-6275C failed a stroke test, was declared inoperable, and the affected penetration was not closed within 4 hours4.62963e-5 days <br />0.00111 hours <br />6.613757e-6 weeks <br />1.522e-6 months <br /> as required. When identified by the licensee during investigation of the failed test, on June 9, Technical specification 3.6.4 was invoked and the penetration was isolated by closing a manual isolation valve. The issue was documented in the corrective action program as CR 2008-18474. The finding was of very low safety significance because manual isolation of the penetration remained available, if needed in an event, and redundant mitigating trains of auxiliary feedwater remained available |
