| ENS 44188 | 5 May 2008 17:03:00 | This is all eight-hour non-emergency reportable event to the NRCOC in accordance with 10 CFR 50.72 (b)(3)(v)(D) for a condition that could have prevented the fulfillment of a safety function. High Head Safety Injection (HHSI) pump discharge to cold leg injection isolation valve 4-867 was discovered out of position while in a refueling outage (4-24.) The valve was discovered out of position on 5/5/08 at 12:37 and placed in its correct position, locked open and back-seated, at 13:07. Valve 4-867 is required to be locked open and back-seated when the reactor coolant system (RCS) temperature is greater than 380 degrees F, per Technical Specification 3.5.2. Unit 4 was in Technical Specification 3.0.3 (no OPERABLE cold leg injection flowpath for all HHSI pumps to Unit 4) for 30 minutes from time of discovery at 12:37 until correction at 13:07. Valve 4-867 was out of its required position for 5 hours and 26 minutes when the RCS was above 380 degrees F at 07:41 until it was correctly repositioned at 13:07. The licensee notified the NRC Resident Inspector. |
