VIRGINIA ELECTRIC A N D POWER COMPANY RICHMOND, VIRGINIA 23261 November 16, 2004 U.S. Nuclear Regulatory Commission Serial No. 04-380B Attention: Document Control Desk NL&OS/ETS RO Washington, D.C. 20555 Docket Nos. 50-3381339 License Nos. NPF-4/7 VIRGINIA ELECTRIC AND POWER COMPANY (DOMINION)

NORTH ANNA POWER STATION UNITS 1 AND 2 EDITORIAL CORRECTION FOR PROPOSED TECHNICAL SPECIFICATIONS CHANGE REQUEST REACTOR COOLANT SYSTEM PRESSURE/TEMPERATURE LIMITS LTOPS SETPOINTS AND LTOPS ENABLE TEMPERATURES In a letter dated July 1, 2004 (Serial No.04-380), Dominion requested an amendment to Facility Operating License Numbers NPF-4 and NPF-7 in the form of changes to the Technical Specifications for North Anna Power Station Units 1 and 2. The proposed changes will provide Reactor Coolant System (RCS) pressurehemperature (PIT) operating limits, Low Temperature Overpressure Protection System (LTOPS) setpoint allowable values, and LTOPS enable temperature (Tenable) values to cumulative core burnups up to 50.3 Effective Full Power Years (EFPY) and 52.3 EFPY, which correspond to the period of the renewed license, for Units 1 and 2, respectively. During a recent review of the proposed technical specification change, a typographical error was identified in the proposed Technical Specification package. Specifically, the cooldown rate was incorrect in the title of Figure 3.4.4-2. The corrected marked-up and proposed pages are provided in the attachment to this letter.

Dominion continues to request a six-month implementation period to accommodate the numerous licensing basis changes necessary to implement the revised pressure/temperature limits. The current pressure/temperature limits remain valid to the years 2018 (32.3 EFPY) and 2020 (34.3 EFPY) for North Anna Unit 1 and 2, respectively. The extended implementation time will have no impact on safe operation of North Anna Units 1 and 2.

Should you have any questions or require additional information, please contact Mr. Thomas Shaub at (804) 273-2763.

Very truly yours, Leslie N. Hartz Vice President - Nuclear Engineering Attachment
