UNITED STATES NUCLEAR REGULATORY COMMISSION WASHINGTON, D.C. 20555*0001 August 22, 2014 Mr. David A. Heacock President and Chief Nuclear Officer Virginia Electric and Power Company lnnsbrook Technical Center 5000 Dominion Boulevard , Glen Allen, VA 23060-6711

SUBJECT:

NORTH ANNA POWER STATION, UNIT NOS. 1 AND 2-AUDIT OF THE LICENSEE'S MANAGEMENT OF REGULATORY COMMITMENTS (TAC NO. MF4565 AND MF4566)

Dear Mr. Heacock:

In U.S. Nuclear Regulatory Commission (NRC) Regulatory Issue Summary 2000-17, "Managing Regulatory Commitments Made by Power Reactor Licensees to the NRC Staff," dated September 21, 2000, the NRC informed licensees that the Nuclear Energy Institute (NEI) document NEI 99-04, "Guidelines for Managing NRC Commitment Changes," contains acceptable guidance for controlling regulatory commitments and encouraged licensees to use the NEI guidance or similar administrative controls to ensure that regulatory commitments are

• implemented and that changes to the regulatory commitments are evaluated and, when appropriate, reported to the NRC. The NRC Office of Nuclear Reactor Regulation has instructed its staff to perform an audit of licensees' commitment management programs once every 3 years to determine whether the licensees' programs are consistent with the industry guidance in NEI 99-04, and that the regulatory commitments are being effectively implemented. An audit of the North Anna Power Station commitment management program was performed at the plant site on June 26, 2014. Based on the audit, the NRC staff concludes that Virginia Electric and Power Company (the licensee) has implemented NRC commitments on a timely basis and has implemented its program for managing NRC commitment changes. The details of the results of the audit are set forth in the enclosed audit report.

• I appreciate the assistance and support provided by your licensing staff, particularly Mr. Jay Leberstien, Mr. Page Kemp and Mr. Tom Shaub.

D. A. Heacock If you have any questions, please contact me at 301-415-2597 or via e-mail at v.sreenivas@ nrc.gov. Docket Nos. 50-338 and 50-339

1.0 INTRODUCTION

AND BACKGROUND In Regulatory Issue Summary 2000-17, "Managing Regulatory Commitments Made by Power Reactor Licensees to the NRC [Nuclear Regulatory Commission] Staff," dated September 21, 2000, the NRC informed licensees that the Nuclear Energy Institute (NEI) document NEI 99-04, "Guidelines for Managing NRC Commitment Changes," contains acceptable guidance for controlling regulatory commitments and encouraged licensees to use the NEI guidance or similar administrative controls to ensure that regulatory commitments are implemented and that changes to the regulatory commitments are evaluated and, when appropriate, reported to the NRC. The NRC Office of Nuclear Reactor Regulation (NRR) has instructed its staff to perform an audit of licensees' commitment management programs once every 3 years to determine whether the licensees' programs are consistent with the industry guidance in NEI 99-04, and that the regulatory commitments are being effectively implemented. NEI-99-04 defines a regulatory commitment as an explicit statement to take a specific action agreed to, or volunteered by, a licensee and submitted in writing on the docket to the NRC. NRR guidelines direct the NRR Project Manager to audit the licensee's commitment management program by assessing the adequacy of the licensee's implementation of a sample of commitments made to the NRC in past licensing actions (amendments, reliefs, exemptions, etc.) and activities (bulletins, generic letters, etc.). The audit is to be performed every 3 years. 2.0 AUDIT PROCEDURE AND RESULTS The regulatory commitment management audit was previously performed at North Anna Power Station, Unit Nos. 1 and 2 (NAPS) on August 8, 2011, covering the period of approximately 3 years. The current audit was performed at NAPS on June 26, 2014, verifying the regulatory commitments made by Virginia Electric and Power Company (the licensee) since the previous audit. " The audit consisted of two major parts: (1) verification of the licensee's implementation of NRC commitments that have been implemented and (2) verification of the licensee's program for managing changes to NRC commitments. Enclosure 2.1 Verification of Licensee's Implementation of NRC Commitments The primary focus of this part of the audit is to confirm that the licensee has implemented commitments made to the NRC as part of past licensing actions/activities. For commitments not yet implemented, the NRC staff determines whether they have been captured in an effective program for future implementation.

• 2.1.1 Audit Scope

• The audit addressed a sample of commitments made during the review period. The audit focused on regulatory commitments (as defined above) made in writing to the NRC as a result of past licensing actions (amendments, exemptions, etc.) or licensing activities (bulletins, generic letters, etc.). Before the audit, the NRC staff searched ADAMS (Agencywide Documents Access and Management System) for the licensee's sLJbmittals since the last audit and selected a representative sample for verification. The audit excluded the following types of commitments that are internal to licensee processes: (1) Commitments made on the licensee's own initiative among internal organizational components. (2) Commitments that pertain to milestones of licensing actions/activities (e.g., respond to an NRC request for additional information by a certain date). Fulfillment of these commitments was indicated by the fact that the subject licensing action/activity was completed. (3) Commitments made as an internal reminder to take actions to comply with existing regulatory requirements such as regulations, Technical Specifications (TSs), and Updated Final Safety Analysis Reports. Fulfillment of these commitments was indicated by the licensee having taken timely action in accordance with the subject requirements.

• 2.1.2 Audit Results The attached Audit Summary provides details of the audit and its results. The NRC staff reviewed documents generated by the licensee for the commitments listed in Table 1. After identification, most commitments were managed through the NAPS Central Reporting System. The NRC staff found that the licensee had properly addressed each regulatory commitment selected for this audit. As a result of reviewing the licensee's information, as well as information from other sources, the NRC staff found no reason to differ from the licensee's reported status of the audited commitments. Thus, the NRC staff concludes that the procedure used by the licensee to manage commitments is appropriate and effective. 2.2 Verification of the Licensee's Program for Managing NRC Commitment Changes The primary focus of this part of the audit is to verify that the licensee has established administrative controls for modifying or deleting commitments made to the NRC. The NRC staff compared the licensee's process for controlling regulatory commitments to the guidelines in NEI-99-04, which the NRC has found to be an acceptable guide for licensees to follow for managing and changing commitments. The process used at NAPS is contained in "Commitment Management," LI-AA-110, Revision 0. In general, LI-AA-110, Revision 0, follows the guidance of NEI-99-04; it sets forth the need for identifying, tracking, and reporting commitments, and it provides a mechanism for changing commitments. The audit reviewed a sample of commitment changes that included changes that were or will be reported to the NRC. The audit also verifies that the licensee's commitment management system includes a mechanism to ensure traceability of commitments following initial implementation. This ensures that licensee personnel are able to recognize that future proposed changes to the affected design features or operating practices require evaluation in accordance with the commitment change control process.

3.0 CONCLUSION

The NRC staff concludes, based on the above audit: (1) the licensee has generally implemented regulatory commitments on a timely basis, and (2) the licensee has implemented an effective . program to manage regulatory commitment changes. 4.0 LICENSEE PERSONNEL CONTACTED FOR THIS AUDIT Jay Leberstien, Technical Advisor, Station Licensing, North Anna Power Station, Mineral, VA Tom Shaub, Licensing Management Contact, lnnsbrook Technical Center, Glen Allen, VA Principal Contributor: V.
