AUDIT REPORT BY THE OFFICE OF NUCLEAR REACTOR REGULATION (NRR)

REGULATORY COMMITMENTS MADE BY THE LICENSEE TO THE NUCLEAR REGULATORY COMMISSION (NRC)

WATTS BAR NUCLEAR PLANT UNIT 1 DOCKET NO. 50-390

1.0 INTRODUCTION AND BACKGROUND

NRR Office Instruction LIC-105, Managing Regulatory Commitments Made by Licensees to the NRC, was published on May 27, 2003, and 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 (ADAMS Accession Number ML022750041). LIC-105 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 Institute (NEI), NEI 99-04, Guidance for Managing NRC Commitment Changes.

According to LIC-105, which cites the definition from NEI-99-04, 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 the issuance of LIC-105, the NRC staff defined the period covered by this audit to go back approximately 3 years. The audit was performed at the Watts Bar Nuclear Plant Licensing Office in Spring City, Tennessee, between May 2 and May 4, 2006.

2.1 Verification of Licensees Implementation of NRC Commitments The primary focus of this part of the audit is to confirm that the licensee has implemented those commitments made to the NRC as part of past licensing activities. The staff examined a sample of completed commitments to ensure that they were implemented in a manner that satisfied both the action committed to and the overall intent of the commitment. The staffs findings are summarized in the attached table.

2.2 Verification of Licensees Program for Managing NRC Commitment Changes The primary focus of this part of the audit is the licensees performance related to implementing controls for modifying or deleting commitments made to the NRC. The staff examined the licensees commitment tracking system and the NRC commitment management procedures.

When the licensee incorporates commitments into plant procedures, they include the commitment tracking number within the procedure. If the commitment is to be deleted from plant procedures, the licensees procedures direct their staff to use the Commitment Evaluation Form, which is similar to that of NEI-99-04.

In addition, the licensee submits a Commitment Summary Report to the NRC every 18 months that captures the modifications and/or deletion of commitments and provides an explanation of the licensees basis for these changes. There were no changes to commitments made in the 3-year period over which the audit was performed; however, the staff did examine a sample of commitment changes made in 2001 and 2002, and determined that the modification and/or deletion of commitments were made in accordance with the licensees programs and procedures. The majority of the changes made were deletions based on the incorporation of the action into owner-controlled documents such as the UFSAR. Furthermore, the licensees technical evaluations adequately justified the change, and the NRC was informed of commitment changes that have safety or regulatory significance. The licensees procedures for changing commitments follow NEI-99-04.

3.0 CONCLUSION

Based on the above, the NRC staff concludes that; (1) the licensee had implemented or is tracking for future implementation regulatory commitments, and (2) the licensee had implemented an effective program to manage regulatory commitment changes.
