UNITED STATES NUCLEAR REGULATORY COMMISSION REGION II 245 PEACHTREE CENTER AVENUE NE, SUITE 1200 ATLANTA, GEORGIA 30303-1257 September 30, 2011 CAL No. 2-2011-001 Mr. David A. Heacock President and Chief Nuclear Officer Virginia Electric and Power Company Innsbrook Technical Center 5000 Dominion Boulevard Glen Allen, VA 23060-6711

SUBJECT:

CONFIRMATORY ACTION LETTER - NORTH ANNA POWER STATION UNIT NOS. 1 AND 2, COMMITMENTS TO ADDRESS EXCEEDING DESIGN BASES SEISMIC EVENT (TAC NOS. ME7050 AND ME7051)

Dear Mr. Heacock:

As reported to the Nuclear Regulatory Commission (NRC or Commission) in licensee event report, EN47201, and updated on September 9, 2011, North Anna Power Station (NAPS) experienced vibratory ground motion in excess of its operating and design basis. In accordance with Appendix A to Title 10 of the Code of Federal Regulations, Part 100, paragraph V(a)(2), a nuclear power plant is required to be shutdown when the vibratory ground motion exceeds that of the Operating Basis Earthquake (OBE). In addition, the regulations state that "prior to resuming operations, the licensee will be required to demonstrate to the Commission that no functional damage occurred to those features necessary for continued operation without undue risk to the health and safety of the public."

On August 23, 2011, during a seismic event which exceeded the plant's OBE, both NAPS units experienced automatic trips and entered Mode 3; subsequently, both units were taken to cold shutdown - Mode 5. On September 17, 2011, the fuel was removed from NAPS Unit 2 placing it in no Mode to allow for inspections.

On September 17, 2011, you submitted the NAPS Units 1 and 2 Summary Report of the August 23, 2011 Earthquake Response and Restart Readiness Determination Plan (Agencywide Documents Access and Management System (ADAMS) Accession Number ML11262A151), stating the impacts of the event and the near-term activities planned for completion to demonstrate that no functional damage has occurred to those features necessary for the continued operation without undue risk to the health and safety of the public. In the cover letter you requested NRC concurrence to restart NAPS Units 1 and 2 upon completion of the remaining near-term action items. In addition, in a conference call between you, Eric Leeds, Director, Office of Nuclear Reactor Regulation and myself, on September 23, 2011, you reiterated your commitment to keep both North Anna Units 1 and 2 shutdown until you receive NRC approval for restart.

D. Heacock 2 This Confirmatory Action Letter (CAL) confirms that NAPS Units 1 and 2 will not enter Modes 1 - 4 (as defined in the technical specifications), until the Commission has completed its review of your information, performed confirmatory inspections, and completed its safety evaluation review. The permission to resume operations will be formally communicated to Virginia Electric and Power Company (VEPCO) in a written correspondence.

VEPCO shall submit to the NRC all documentation requested by the NRC as being necessary to demonstrate that NAPS Units 1 and 2 can be operated safely following the seismic event that exceeded the safe shutdown event analyzed in the current revision of the Updated Final Safety Analysis Report.

This CAL will remain in effect until the NRC has (1) reviewed your information, including responses to staff's questions and the results of your evaluations, and (2) the staff communicates to you in written correspondence that it has concluded that NAPS can be operated without undue risk to the health and safety of the public or the environment.

Pursuant to Section 182 of the Atomic Energy Act of 1954, as amended (42 U.S.C. 2232), you are required to:

1) Notify me immediately if your understanding differs from that set forth above; 2) Notify me if for any reason you cannot complete the actions; and

3) Notify me in writing when you have completed the actions addressed in this Confirmatory Action Letter.

In accordance with 10 CFR 2.390 of the NRC's regulations a copy of this letter, and any response will be made available electronically for public inspection in the NRC Public Document Room or from the ADAMS, accessible from the NRC Web site at http://www.nrc.gov/reading-rm/adams.html. To the extent possible, your response should not include any personal privacy, proprietary, or safeguards information so that it can be made available to the Public without redaction. If personal privacy or proprietary information is necessary to provide an acceptable response, then please provide a bracketed copy of your response that identifies the information that should be protected and a redacted copy of your response that deletes such information. If you request withholding of such material, you must specifically identify the portions of your response that you seek to have withheld and provide in detail the bases for your claim of withholding (e.g., explain why the disclosure of information will create an unwarranted invasion of personal D. Heacock 3 privacy or provide the information required by 10 CFR 2.390(b) to support a request for withholding confidential commercial or financial information). If safeguards information is necessary to provide an acceptable response, please provide the level of protection described in 10 CFR 73.21.

Sincerely, /RA/
