SUBJECT:
NORTH ANNA POWER STATION, UNITS 1 AND 2 - AUDIT OF VIRGINIA ELECTRIC AND POWER COMPANYS MANAGEMENT OF REGULATORY COMMITMENTS (TAC NOS. MC3323 AND MC3324)
Dear Mr. Christian:
On May 27, 2003, the Office of Nuclear Reactor Regulation Office Instruction LIC-105, Managing Regulatory Commitments Made by Licensees to the NRC [Nuclear Regulatory Commission], was published. LIC-105 provides the NRC staff and its stakeholders with a common reference for handling regulatory commitments made to the NRC by licensees for commercial nuclear reactors. The guidance is consistent with the industry guidance prepared by the Nuclear Energy Institutes (NEIs) NEI 99-04, Guidance for Managing NRC Commitment Changes. LIC-105 specifies that once every 3 years the NRC staff will audit a licensees commitment management program.
On June 23, 2004, the NRC staff performed an audit of Virginia Electric and Power Companys (VEPCOs) commitment management program at North Anna Power Station, Units 1 and 2.
The NRC staff concludes that based on the audit (1) VEPCO had implemented NRC commitments on a timely basis, and (2) VEPCO had implemented an effective program for managing NRC commitment changes. Details of the audit are set forth in the enclosed audit report.
Sincerely,
/RA/
Stephen Monarque, Project Manager, Section 1 Project Directorate II Division of Licensing Project Management Office of Nuclear Reactor Regulation Docket Nos. 50-338 and 50-339

1.0 INTRODUCTION
On May 27, 2003, the NRR Office Instruction LIC-105, Managing Regulatory Commitments Made by Licensees to the NRC, was published. LIC-105, which is publicly available electronically from the Agencywide Documents Access and Management Systems (ADAMS)
Public Electronic Reading Room on the Internet at the NRC web site (Accession Number ML022750041), provides the NRC staff and its stakeholders with a common reference for handling regulatory commitments made by licensees for commercial nuclear reactors to the NRC staff. The guidance is consistent with the industry guidance prepared by the Nuclear Energy Institutes (NEIs) NEI 99-04, Guidance for Managing NRC Commitment Changes.
According to LIC-105 a regulatory commitment is 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. LIC-105 further directs the NRR Project Manager to audit the licensees commitment management program by assessing the adequacy of the licensees 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 Since no such audit was performed before issuance of LIC-105, the NRC staff defined the period covered by this audit to go back approximately 3 years from the date of the audit. The audit was performed at North Anna Power Station on June 23, 2004.
The primary focus of the audit was to confirm that Virginia Electric and Power Company (VEPCO) has implemented those commitments made to the NRC as part of past licensing actions/activities. For commitments that had not yet been implemented, the NRC staff ascertained that they had been captured in an effective program for future implementation.
2.1 Audit Scope Before the audit, the NRC staff searched ADAMS for VEPCOs licensing action and licensing activity submittals dated in the last 3 years. These commitments are shown on Table 1.
Enclosure
VEPCOs commitments are tracked by the Corrective Action System. The Corrective Action System is a computer database that is used to assign and track commitments to an effective completion. Commitments that are entered into the Corrective Action System are either tracked as a Plant Issue Resolution or on a Commitment Data form. Most of VEPCOs commitments that are shown on Table 1 were tracked as a Plant Issue Resolution. During the June 23, 2004 audit, the NRC staff reviewed the Plant Issue Resolution reports, VEPCOs submittals, and other documents related to the commitments.
LIC-105 limits the audit of commitments to those made in writing to the NRC as a result of past licensing actions (amendments, exemptions, etc.) or licensing activities (bulletins, generic letters, etc.). Accordingly, the audit excluded the following types of commitments:
(1) Commitments as a result of Licensee Event Reports (LERs) - These commitments are controlled by VEPCOs LER process, which is imposed by Title 10 of the Code of Federal Regulations (10 CFR) Section 50.73.
(2) Commitments made on VEPCOs own initiative among internal organizational components and not reported to the NRC staff.
(3) Commitments integrated into the Updated Final Safety Analysis Reports, Quality Assurance Program, Site Security Plan, Emergency Plan, or other documents governed by a change control mechanism contained in regulations such as 10 CFR 50.59 or 50.54.
2.2 Audit Results The NRC staff reviewed reports generated by the Corrective Action System for the commitments listed in Table 1 in order to evaluate the status of completion. The NRC staff found that VEPCOs commitment tracking program had captured all of the pending regulatory commitments that were identified by the NRC staff. The NRC staff also reviewed plant issue resolutions that had been revised as a result of commitments made by VEPCO to NRC. These procedures are identified in the right-hand column of Table 1.
The NRC staff reviewed several of VEPCOs commitments that had been impacted by the replacement of the reactor pressure vessel (RPV) heads. VEPCO had committed to several inspections of the RPV upper heads; however, these inspections were no longer being performed because these heads had been replaced. For instance, the NRC staff reviewed VEPCOs commitment to perform bare-metal visual inspections of the RPV upper heads during future refueling outages (RFOs) at North Anna until these heads were replaced. Because VEPCO replaced the RPV upper heads in a subsequent RFO, this negated the need to continue to perform these inspections. Therefore, the NRC staff considers this commitment to have been completed.
By letter dated November 5, 2001, VEPCO committed to inspect Penetration Nos. 3, 11, 31, 33, 52, 57, 60, and 66 at North Anna, Unit 1 during subsequent RFOs. While performing an RPV upper head examination during the fall 2001 RFO, VEPCO had discovered relevant indications on these eight penetrations. As a result, VEPCO made a commitment to inspect these eight penetrations. Additionally, as part of its response to Bulletin 2002-02, Reactor Pressure Vessel Head and Vessel Head Penetration Nozzle Inspection Programs, dated September 12, 2002, VEPCO made another commitment to perform a bare-metal visual and best effort
non-visual inspection of the RPV upper head at North Anna during the next RFO for each unit.
During the spring 2003 and fall 2002 RFOs, VEPCO replaced the RPV upper heads for North Anna, Units 1 and 2, respectively. This action nullified the need to inspect the replaced RPV upper heads and their penetrations. Furthermore, NRC Order EA-03-009, Issuance of First Revised NRC Order Establishing Interim Inspection Requirements for Reactor Pressure Vessel Heads at Pressurized Water Reactors, dated February 20, 2004, provides the inspection requirements for the replacement RPV upper heads. As such, the NRC staff considers these commitments involving the inspection of the replaced RPV upper heads to be completed.
2.3 Verification of VEPCOs Program for Managing NRC Commitment Changes The NRC staff reviewed VEPCOs procedure entitled Commitment Management, VPAP-2801, Revision 3, against NEI 99-04. Attachments 3 and 4 of VPAP-2801, Revision 3 provide details on the commitment management process that closely follows the guidance of NEI-99-04. In general, VPAP-2801, Revision 3 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 NRC staff found that VEPCO had properly addressed each regulatory commitment selected for this audit. As a result of reviewing VEPCOs information, as well as information from other sources, the NRC staff found no reason to differ from VEPCOs reported status of the audited commitments. Thus, the NRC staff concludes that the procedure used by VEPCO to manage commitments is appropriate and effective.
3.0 CONCLUSION
The NRC staff concludes that based on the above audit: (1) VEPCO had implemented, or is tracking for future implementation, regulatory commitments; and (2) VEPCO had implemented an effective program to manage regulatory commitment changes.
