10 CFR 50.90 VIRGINIA ELECTRIC AND POWEIR COMPANY RICHNMOND, VIRGINIA 23261 February 12, 2004 U. S. Nuclear Regulatory Commission Serial No. 03-494A Attention: Document Control Desk NLOS/ETS Washington, D.C. 20555 Docket Nos. 50-338 50-339 License Nos. NPF-4 NPF-7 VIRGINIA ELECTRIC AND POWER COMPANY (DOMINION)
NORTH ANNA POWER STATION UNITS 1 AND 2 REVISED COMPENSATORY MEASURES EXTENDED INVERTER ALLOWED OUTAGE TIME PROPOSED RISK-INFORMED TECHNICAL SPECIFICATIONS CHANGE In a December 13, 2002 letter (Serial No.02-758), Dominion requested an amendment to Facility Operating License Numbers NPF-4 and NPF-7 in the form of a change to the Technical Specifications for North Anna Power Station Units 1 and 2. The proposed change would revise the Completion Time of Required Action A.1 of Technical Specification 3.8.7, Inverter-Operating, from 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> to 14 days based on a risk-informed evaluation for an inoperable inverter. Based on a September 11, 2003 telephone conversation with the NRC regarding the deterministic basis of the Technical Specification, Dominion submitted by letter dated December 17, 2003 (Serial No.03-494), a revised Technical Specification change. The proposed revision to the Technical Specification modified TS 3.8.7, Required Action A.1 Completion Time from 14 days to 7 days and identified two compensatory measures that would be implemented when an instrument bus inverter is unavailable.
In a follow up telephone conversation with the NRC staff on February 9, 2004, implementation of compensatory measures associated with inverter unavailability was discussed. Based on that conversation, Dominion has modified the compensatory measure associated with maintenance of Reactor Protection System/Engineered Safety Feature Actuation System channels during a planned instrument bus inverter outage.
The following compensatory measures will be implemented when an instrument bus inverter is unavailable:
Entry into the extended inverter Completion Time will not be planned concurrent with EDG maintenance, and k 'o/
10 CER 50.90
- Entry into the extended inverter Completion Time will not be planned concurrent with planned maintenance on another RPS/ESFAS channel that results in that channel being in a tripped condition.
Dominion requests NRC approval of the proposed Technical Specification change by February 29, 2004. Once approved, the amendment will be implemented within 30 days. Should you have any questions or require additional information, please contact Mr. Thomas Shaub at (804) 273-2763.
Very truly yours, K.,
Leslie N. Hartz Vice President Nuclear Engineering Commitments made in this letter:
The following modified compensatory measures will be implemented when an instrument bus inverter is unavailable:
- Entry into the extended inverter Completion Time will not be planned concurrent with EDG maintenance, and
- Entry into the extended inverter Completion Time will not be planned concurrent with planned maintenance on another Reactor Protection System/Engineered Safety Feature Actuation System channel that results in that channel being in a tripped condition.
