VIRGINIA ELECTRIC AND POWER COMPANY RICHMOND, VIRGINIA 23261 June 5, 2018 10 CFR 50 Appendix H U.S. Nuclear Regulatory Commission Serial No.: 18-098A Attention: Document Control Desk NRA/GDM: RO Washington, DC 20555-0001 Docket Nos.: 50-280/281 License Nos.: DPR-32/37 VIRGINIA ELECTRIC AND POWER COMPANY (DOMINION ENERGY VIRGINIA)

SURRY POWER STATION UNITS 1 AND 2 REVISED REACTOR VESSEL MATERIALS SURVEILLANCE CAPSULE WITHDRAWAL SCHEDULES - EDITORIAL CORRECTION By letter dated July 28, 2017, Serial No.17-243, (Agencywide Documents Access and Management System (ADAMS) Accession No. ML17213A080), Dominion Energy Virginia submitted a request for NRG review and approval of proposed reactor vessel material surveillance capsule withdrawal schedules for Surry Power Station (Surry)

Units 1 and 2 in accordance with Title 10 of the Code of Federal Regulations (10 CFR)

Part 50, Appendix H, Reactor Vessel Material Surveillance Program Requirements.

The proposed withdrawal schedules address revisions to the surveillance capsule withdrawal schedules approved for the 40 to 60-year period of extended operation (PEO).

Subsequent to that submittal, an editorial error was recently identified in the revi.sed Table 4.1-13, "Surveillance Capsule Withdrawal Schedule for Surry Unit 2."

Specifically, the existing Estimated Withdrawal EFPY/Year values provided for Capsules S and W1 in the table were inadvertently reversed. It should be noted this information is not being revised as part of the original request. The corrected revised Table 4.1-13 is provided in the attachment with the corrected values highlighted for easy reference.

Should you have any questions or require additional information, please contact Mr. Gary D. Miller at (804) 273-2771.

Sincerely,

~*-
