Title	Primary Containment Penetration Isolation Valves Inoperable
Event Description	During a review of outage clearances, it was discovered that a Caution tag out for Service Air to the Drywell was active and the valves were open. This rendered the valves inoperable and Technical Specification 3.6.1.3 action B for one penetration with two inoperable PCIVs was entered. The action was to isolate the penetration by closing one valve within one hour. The event was discovered at 0530 and the outboard valve was closed at 0655 . Since the one hour time limit was exceeded, Technical Specification 3.6.1.3 action E (Mode 3 in 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> and Mode 4 in 36 hours4.166667e-4 days <br />0.01 hours <br />5.952381e-5 weeks <br />1.3698e-5 months <br />) was entered at 0630 and exited at 0655. Technical Specification 3.6.1.3 action A, which is the Tech. Spec. for one inoperable isolation valve will remain in effect. The plant entered Mode 3 at 1530 on 10/01/04. Mode 3 requires primary containment and all PCIVs to be operable. This condition of non-compliance existed from 1530 on 10/01/04 until 0655 on 10/03/04. The licensee notified the NRC Resident Inspector.
