NORTH ANNA POWER STATION UNIT 2 WITHDRAWAL OF PROPOSED LICENSE AMENDMENT REQUEST (LAR)

TS 3.8.1 - AC SOURCES - OPERATING REVISED SURVEILLANCE REQUIREMENT In a September 10, 2013 letter (Serial No.13-423), Dominion requested an amendment, in the form of a change to the Technical Specifications (TS) to Facility Operating License Number NPF-7 for North Anna Power Station Unit 2 to modify Surveillance Requirement (SR) 3.8.1.8, which requires verification of the capability to manually transfer Unit 1 4.16 kV ESF bus AC power sources from the normal offsite circuit to the alternate required offsite circuit. At this time Dominion is withdrawing the proposed LAR.

The LAR as written, and included in the TS Bases, requires that if one alternate feed is used then the other Unit 2 alternate feed is to be placed in service to ensure two qualified offsite power sources are available to meet TS 3.8.1 (and satisfy GDC-17). In order to eliminate the unnecessary restriction that is included in the proposed LAR, Dominion intends to re-evaluate additional station electrical distribution configurations that would satisfy GDC-17 requirements. The reevaluation effort is underway and will require approximately 4 months to complete, including verification and validation of each possible electrical configuration. At that time, Dominion plans to submit a revised LAR that will eliminate the restriction and address the qualified GDC-17 electrical configurations.

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

Very truly yours, Thomas R. Huber - Director Nuclear Licensing and Operations Support Dominion Resources Services, Inc.
