VIRGINIA ELECTRIC AND POWER COMPANY (DOMINION)

NORTH ANNA POWER STATION UNITS I AND 2 IMPROVED TECHNICAL SPECIFICATIONS CORRECTION OF ADMINISTRATIVE ERROR (TAC Nos. MB0799 AND MB0800)

On April 5, 2002, the Nuclear Regulatory Commission issued Amendment Nos. 231 and 212 to Facility Operating License Nos. NPF-4 and NPF-7 for the North Anna Power Station, Unit Nos. 1 and 2 (letter Serial No.02-275). These amendments converted our current Technical Specifications (CTS) to a set of improved Technical Specifications (ITS), based on NUREG-1431, "Standard Technical Specifications, Westinghouse Plants."

In preparing to implement these amendments, we have identified an administrative error in Technical Specification 3.3.1, page 17. The inequality associated with rt3 should be not "_." In our CTS, we refer to what is called 't7 in NUREG-1431 as T3. In converting to the ITS, we inadvertently adopted the inequality sign convention of the NUREG's -r3 for our T3, which is not correct. We should have adopted the inequality sign convention for the NUREG's 7.

Therefore, we are requesting that the NRC issue a revised page to Amendments 231 and 212 to the Facility Operating Licenses for North Anna Power Station, Unit Nos. 1 and 2. The revised page, which is attached, corrects the administrative error. Also, the page that was originally issued by the NRC is attached, with the change shown.

To avoid unnecessary administrative burden and support the current ITS implementation schedule, we request that you issue the revised page by June 30, 2002.

If you have any further questions or require additional information, please contact us.

Very truly yours, Leslie N. Hartz Vice President - Nuclear Engineering Attachment Commitments made in this letter: None cc:
