UNITED STATES NUCLEAR REGULATORY COMMISSION WASHINGTON, D.C. 20555-0001 January 17, 2012 Mr. John T. Conway Senior Vice President

-Energy Supply and Chief Nuclear Officer Pacific Gas and Electric Company Diablo Canyon Power Plant 77 Beale Street, Mail Code B32 San Francisco, CA 94105 DIABLO CANYON POWER PLANT, UNIT NOS. 1 AND 2 -AUDIT OF THE LICENSEE'S MANAGEMENT OF REGULATORY COMMITMENTS (TAC NOS. ME7284 AND ME7285)

Dear Mr. Conway:

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 Diablo Canyon Power Plant, Units 1 and 2, commitment management program was performed at the plant site during the period October 18-21, 2011. Based on the audit, the NRC staff concludes that Pacific Gas and Electric Company (the licensee) has implemented NRC commitments on a timely basis, and has implemented its program for managing NRC commitment changes with programmatic inconsistencies and deficiencies noted. The details of the results of the audit are set forth in the enclosed audit report.

J. Conway If you have any questions, please contact me at 301-415-1445 or via e-mail at alan. wang@nrc.gov.

AUDIT REPORT BY THE OFFICE OF NUCLEAR REACTOR REGULATION LICENSEE MANAGEMENT OF REGULATORY COMMITMENTS PACIFIC GAS AND ELECTRIC COMPANY DIABLO CANYON POWER PLANT. UNITS 1 AND 2 DOCKET NOS. 50-275 AND 50-323

1.0 INTRODUCTION

AND BACKGROUND 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 (Agencywide Documents Access and Management System (ADAMS) Accession No. ML003741774), 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 enSIJre 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.

relief requests, exemptions, etc.) and activities (bulletins, generic letters, etc.). The audit is to be performed every 3 years. 2.0 AUDIT PROCEDURE AND RESULTS An audit of the Diablo Canyon Power Plant, Units 1 and 2 (DCPP), commitment management program was performed at the plant site during the period October 18-21, 2011, and discussed during a teleconference on November 10, 2010, with members of the Pacific Gas and Electric Company (PG&E, the licensee) staff. The audit reviewed commitments made by the licensee Enclosure

-2 since the previous audit on September 17-18, 2008, which was documented in an audit report dated October 22, 2008 (ADAMS Accession No. Ml082800342).

The audit consisted of two major parts: (1) verification of the licensee's implementation of NRC commitments that have been completed, and (2) verification of the licensee's program for managing changes to NRC commitments. 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. 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, relief requests, exemptions, etc.) or licensing activities (bulletins, generic letters, etc.). Before the audit, the NRC staff performed a search in ADAMS for the licensee's submittals 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: Commitments made on the licensee's own initiative among internal organizational components. 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. Commitments made as an internal reminder to take actions to comply with existing regulatory requirements such as regulations, Technical Specifications, 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. Audit Results The attached Audit Summary -Implementation of Commitments (Attachment

1) provides details of the audit and its results. For reference, the licensee's "recurring task" commitments are tracked in the computer-based Procedure Commitment Database (PCD) while "single task" commitments are tracked elsewhere (most typically in the corrective action program and in a regulatory services alone spreadsheet).

The licensee's commitments are managed in accordance with DCPP administrative procedure XI4.ID1, "Commitment Identification and Tracking Process,"

-Revision 6A. For this audit, the NRC staff reviewed the selected sample of open and closed regulatory commitments to confirm that the licensee had implemented closed commitments appropriately, and that commitments still open had been captured in an effective program for future implementation as required by DCPP. The NRC staff reviewed relevant reports and summary sheets from the computer database and other sources (e.g., corrective action documentation, plant procedures, job numbers, documented training, etc.) providing the status of each commitment, form of implementation, and any pending further action. In addition.

the NRC staff reviewed two licensee self assessments of its "NRC Commitment Management" in the "2009 Technical Specification and Testing Audit" dated October 23,2009, and the "2011 Technical Specification Audit" dated October 5, 2011. Based on the review of reports provided by the licensee as described above and on queries of the PCD, the corrective action program, and the regulatory services stand-alone spreadsheet during the audit, the NRC staff found that the licensee has generally implemented commitments on a timely basis (as documented in Attachment 1). 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 the DCPP is contained in administrative procedure XI4.ID2, "Commitment Change Process," Revision 9 with accompanying change form DCPP 69-20200, "Commitment Change Request" dated April 12, 2010. The auditors reviewed a sample of commitment changes that included changes that were or will be reported to the NRC, and changes that were not or will not be reported to the NRC. The auditors also verified that the licensee's commitment management system includes a mechanism to ensure traceability of commitments following initial implementation.

This ensures that the licensee's 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. 2.2.1 Audit Results The attached Audit Summary -Management of Changes to Regulatory Commitments (Attachment

2) provides details of this portion of the audit and its results. The NRC staff reviewed procedure X14.ID2 and its required form to determine whether the licensee had an effective program in place to identify, manage, and close commitments made to the NRC as part of licensing actions/activities.

In addition, the NRC staff reviewed relevant reports and summary sheets from the computer database and other sources providing the status of each commitment, tracking and change forms, and other associated documentation.

The NRC staff compared the guidance in the DCPP administrative procedure X14.ID2 to the guidance in NEI 99-04. As a result of this comparison, the NRC staff found that the DCPP procedure was consistent with the NEI guidance for identifying, managing, and closing commitments and that the roles and responsibilities, processes, and metrics were clearly identified in the DCPP procedure with the following programmatic exceptions: The NRC staff reviewed procedure X14.ID1 and noted in step 3.6.2 that "the following types of commitments are maintained by their respective departments:

a. Security Program Commitments, b. Training Program Commitments." NRC staff interviews with licensee Security and Training (Learning Services) personnel revealed that neither department had established a commitment tracking or management program either formally or informally.

Neither department had created commitment management procedures, nor did they have a list or mechanism to centrally track known and existing departmental commitments.

Additionally, in Action Request (AR) A0641 042, dated June 25,2005, Learning Services specifically stated that "the ability to embed the PCD entry into Training procedures is a very important tool for use by learning services" and that "the use of PCD to register commitments from federal, state, ... , is a keystone to the In this AR, Regulatory Services discussed the use of a new process (nexis) to "improve capabilities

... for management of commitments in RS [regulatory services], LS [learning services], and security." This AR was closed based on the eventual arrival of the new process and the commitment to continue manual tracking of Learning Services commitments.

Based on the above review, the NRC staff identified that this commitment management program gap for Security and Learning Services was originally identified by the licensee as early as June 2005, was discussed generally as item 2.5.(b) in the previous NRC commitment audit report, and was not corrected by the time of this audit with the new process in place. No safety significant issues connected to this programmatic deficiency were noted. The licensee initiated Notification number 50435195 to address this issue. The NRC staff review of XI4.ID1, "Commitment Identification and Tracking Process" revealed that only "recurring task" commitments are entered into the PCD while "single task" commitments are tracked elsewhere (most typically in the corrective action program and in a regulatory services stand-alone spreadsheet).

X14.ID1 states in step 3.2.1 that a single task commitment is "a commitment type that can be resolved and implemented by a one time action that does not require a controlled process to ensure its continued and consistent implementation." NRC staff interviews with the licensee's personnel revealed that while there is not an explicit prohibition to using XI4.ID2, "Commitment Change Process" with its change management flowchart for "single task" commitments, site practice and procedural intent is to utilize X14.ID2 for PCD entered "recurring task" commitments only. Further NRC staff interviews with the licensee's personnel revealed that should there be a change required to a "single task" commitment, then the review process for modification of a corrective action program corrective action would evaluate the change. Following a review of modified "single task" commitments, the NRC staff identified that the NEI 99-04 flowchart guidance within Attachment 1 of X14.ID2 and Form DCP 69-20200 were not being utilized to evaluate the notification or evaluation needed for this commitment change. Attachment 2 below provides specific examples of this issue with recent "single task" commitments.

No safety significant issues connected to this programmatic deficiency were noted. The licensee initiated Notification number 50435196 to address this issue. Based on the review of the reports provided by the licensee as described above, queries of the PCD, the corrective action program, and the regulatory services stand-alone spreadsheet and the accompanying change review and tracking forms provided during the audit, the NRC staff found that the licensee's implementation of its program for managing NRC commitment changes is in accordance with its site procedure with the programmatic deficiencies noted above in the examples documented in Attachment

2.

3.0 CONCLUSION

Based on the audit, the NRC staff concludes that (1) the licensee has generally implemented NRC commitments on a timely basis, and (2) the licensee has implemented its program for managing NRC commitment changes with programmatic inconsistencies and deficiencies noted. 4.0 LICENSEE PERSONNEL CONTACTED FOR THIS AUDIT Steven Zawalick Corrado Sansone Mark Padovan Philippe Soenen Principal Contributor:
