AUDIT REPORT BY THE OFFICE OF NUCLEAR REACTOR REGULATION LICENSEE MANAGEMENT OF REGULATORY COMMITMENTS ENTERGY OPERATIONS INC.

WATERFORD STEAM ELECTRIC STATION, UNIT 3 DOCKET NOS. 50-382

1.0 INTRODUCTION AND BACKGROUND

In Regulatory Issue Summary 2000-17, AManaging Regulatory Commitments Made by Power Reactor Licensees to the NRC Staff,@ dated September 21, 2000, the U.S. Nuclear Regulatory Commission (NRC) informed licensees that the Nuclear Energy Institute (NEI) document NEI 99-04, AGuidelines 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 Aregulatory 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, relief requests, exemptions, etc.) and licensing activities (bulletins, generic letters, etc.).

2.0 AUDIT PROCEDURE AND RESULTS An audit of the Waterford Steam Electric Station, Unit 3 (Waterford 3) commitment management program was performed at the plant site on July 24 and 25, 2008. The audit consisted of two parts: (1) verification of the licensee=s implementation of regulatory commitments that have been completed, and (2) verification of the licensee=s program for managing changes to regulatory commitments.

2.1 Verification of Licensees Implementation of Regulatory 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 actions/activities. For commitments that had not yet been implemented, the NRC staff aimed to ascertain that they have been captured in an effective program for future implementation.

ENCLOSURE

2.1.1 Audit Scope The audit addressed a sample of commitments, majority of which were made during the review period of approximately the last 3 years, and some much older. The audit focused on regulatory commitments made in writing to the NRC as a result of past licensing actions (amendments, exemptions, relief requests, etc.) or licensing activities (bulletins, generic letters, etc.), licensing event reports, and inspection reports.

2.1.2 Audit Results Entergy Operations Inc. (the licensee) has implemented Procedure EN-LI-110, Commitment Management Program,@ which identifies the methods and site organization tools for managing development, review, and implementation of station commitments.

The documents furnished by the licensee during the audit included summary sheets providing the status of the commitments and appropriate backup documentation, as needed (i.e.,

commitment change evaluation form, plant procedures, examination records, and/or other plant documentation). The NRC staff reviewed the documents and summarized the selected commitments information in the attachment to this audit report.

The staff audit was intended to confirm that the licensee has documented its implementation of its regulatory commitments made to the NRC staff as part of past licensing communications, and the commitments that had not yet been implemented or incorporated in design bases documents are captured in an effective manner for future implementation.

The NRC staff audit of the licensees commitment management program for Waterford 3 did not identify any regulatory commitments that were not satisfied or incorporated. The licensee has maintained the database well and the commitments selected for this audit were easily traceable in the database. In case the commitment was already incorporated, the database provided the status of the commitment providing reference to the implementation document.

Based on the results of the on-site audit, the NRC staff believes the licensee has implemented the regulatory commitments management program effectively in accordance with LIC-105, AManaging Regulatory Commitments Made by Licensees to the NRC,@ and consistent with NEI 99-04.

The attachment to this audit report contains details of the audit and a summary of the audit results.

2.2 Verification of the Licensee=s Program for Managing Regulatory Commitment Changes The focus of this part of the audit was to verify that the licensee has established administrative controls for satisfying, modifying, or deleting commitments made to the NRC.

The NRC staff found that the process sets forth the need for identifying, initiating, tracking, and reporting commitments, managing a change or deviation from a previously completed commitment.

As set forth in Section 2.1 above, the NRC staff found that the licensee had addressed each regulatory commitment selected for this audit. As a result of review of the information

provided by the licensee, as well as information from other sources, the NRC staff found no reason to differ from the licensees reported status of the audited commitments. Thus, the NRC staff surmises that the procedure used by the licensee to manage commitments is appropriate and effective 2.2.1 Audit Results The licensee carries out its obligations under its regulatory commitments by the processes that are outlined in the procedures. Any changes to the commitments are processed through the established processes and changes are reported to the NRC in accordance with the recommendations of LIC-105. However, no commitment changes were identified during the audit (for the commitments included in the scope of review), except for change to the implementation date.

The NRC staff audit of Entergys commitment management program did not identify any regulatory commitments that were not satisfied or incorporated. The licensee has maintained the Commitment Management Program at a satisfactory level and the commitments selected for this audit were easily traceable in Program. The Program provided an accurate status of the commitments and provided the reference to the implementation document.

Based on the results of the on-site audit, the NRC staff believes the licensee has implemented regulatory commitment changes appropriately, in accordance with LIC-105 and consistent with NEI 99-04.

3.0 OBSERVATIONS AND RECOMMENDATIONS In the Commitment List, under the columns titled, Text, Comments and Status a short description of the corrective action to be taken, general comments, and the status of the commitment are provided chronologically. While the auditors found that many of these notes contained the author(s) (with initials) and date(s), this was not done in a consistent and uniform manner. Many of the notes lacked the authors identity and the date. The auditors are of the opinion that these additions provide a valuable historical background.

3.0 CONCLUSION

The NRC staff concludes that, based on the above audit, (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.
