Dear Mr. Flores:

In Regulatory Issue Summary 2000-17, "Managing 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, "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 Comanche Peak Nuclear Power Plant (CPNPP), Units 1 and 2, commitment management program was performed at the plant site on August 16-17, 2011. The NRC staff concludes, based on the audit, that Luminant Generation Company LLC (the licensee) has implemented NRC commitments on a timely basis, and (2) the licensee has implemented an effective program for managing NRC commitment changes at CPNPP, Units 1 and 2. The details of the audit including the NRC staff's observations and recommendations are set forth in the enclosed audit report.

UNITED STATES NUCLEAR REGULATORY COMMISSION WASHINGTON, D.C. 20555-0001 AUDIT REPORT BY THE OFFICE OF NUCLEAR REACTOR REGULATION LICENSEE MANAGEMENT OF REGULATORY COMMITMENTS LUMINANT GENERATION COMPANY LLC COMANCHE PEAK NUCLEAR POWER PLANT, UNITS 1 AND 2 DOCKET NOS. 50-445 AND 50-446

1.0 INTRODUCTION AND BACKGROUND

In 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 U.S. Nuclear Regulatory Commission (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, relief requests, exemptions, etc.) and licensing activities (bulletins, generic letters, etc.). The audit is to be performed every 3 years.

2.0 AUDIT PROCEDURE AND RESULTS An audit of the Comanche Peak Nuclear Power Plant (CPNPP), Units 1 and 2 commitment management program was performed at the plant site on August 16-17, 2011. The audit reviewed commitments made since the previous audit on June 9,2008 (audit report issued on July 31,2008 (ADAMS) Accession No. ML081970666). The audit consisted of two major parts:

Enclosure

-2 (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.

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, relief requests, etc.) or licensing activities (bulletins, generic letters, etc.). Before the audit, the NRC staff searched ADAMS for the licensee's submittals since the last audit and selected a representative sample of regulatory commitments for verification. The identified list of commitments was forwarded to the licensee with a request to locate documentation for the listed regulatory commitments ahead of the NRC staff visit.

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, 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 Luminant Generation Company LLC (Luminant, the licensee) has implemented Procedure STA-509, "Commitments Management Program," which identifies the methods and site organization tools for managing development, review, and implementation of station commitments. The licensee's Procedure REG-509, "Nuclear Licensing Commitment Administration," establishes the processes, guidelines, and activities the licensee uses to manage the development, review, and implementation of commitments generated from regulatory obligations and self-imposed requirements. An electronic commitment tracking

- 3 system (ECTS) database is used in conjunction with other information sources to address and track regulatory commitments.

The documents furnished by the licensee during the audit included summary sheets from the ECTS database providing the status of the commitments and appropriate backup documentation, as needed (Le., 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 NRC staff's 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.

As discussed above, the ECTS and commitments material change evaluation (CMCE) provided by the licensee's Procedures STA-509 and REG-509, provide acceptable tools for the licensee to capture the NRC guidance on commitment management programs. The licensee enters the regulatory commitments made to the NRC into a database. The regulatory commitments are labeled as regulatory commitments. Each commitment is numbered and described by a commitment title and brief description. Status of the commitments, implementation dates, target implementation (documents which finally capture the commitment) document information associated with each specific commitment, and comments are captured in the database. The licensee's staff is well trained in updating the commitment management program.

The NRC staff's audit of the licensee's commitment management program for CPNPP, Units 1 and 2, did not identify any regulatory commitments that were not satisfied or incorporated. The licensee has maintained the ECTS database very well and all the commitments selected for this audit were easily traceable in the database. In case the commitment was already incorporated, the database provided an accurate status of the commitment providing reference to the implementation document.

The review did not identify any errors in the ECTS database. A discrepancy in implementing Commitment No. 3618664, as described below, was identified. However, this was only a procedural discrepancy and did not have any safety significance. The licensee was in the process of writing a condition report to remove the discrepancy.

Commitment No.: 3618664 STA-202, Revision 35 "Station Administration Manual - Nuclear Generation Procedure Change Process," Step 2.8.2, requires that for those cases where the entire procedure satisfies the commitment, the [C] designating the entire procedure to satisfy the commitments, should be placed in the left margin for the PURPOSE section (Section 1.0) and the commitment number identified in the REFERENCES section OR the commitment(s) may be identified by commitment number within a step in the procedure. Procedure STA-698 was developed to satisfy Commitment No. 3618664. The procedure did not label Section 1.0, "PURPOSE" with [C], as required by Procedure STA-202. However, the Commitment No. was added to the Reference section and the sections of the

-4 procedure containing the commitment were labeled with [C] (not the commitment number.

To ensure that the regulatory commitments are not removed/changed in future revisions to the target documents, a database search is performed to identify all the open and closed commitments against the document/procedure being revised and it is ensured that all the closed commitments are captured. In addition, the plant procedures require that all the specific regulatory commitments pertaining to the individual document be included in the reference section. This ensures that the commitments are neither removed nor changed without management approval in accordance with the plant procedures.

As a result of the audit in 2008, the NRC staff identified one area with potential for improvement.

The NRC staff recommended that the area of change in the target document should be marked consistently with the regulatory commitment number to ensure that the commitment is easily traceable and eliminates any potential for it to be changed or deleted. The licensee revised its Procedure STA-202 to incorporate this recommendation. The procedure (step 2.8.2) was revised to state:

[C] denotes the incorporation of a CPNPP commitment (See STA-509).

Procedural steps required to be performed due to a station commitment, identified in the commitment tracking system (e.g. SOERs [Significant Operating Experience Reports], NRC items, etc.), should be specified in the left margin by using a [C] except for those cases where the entire procedure, not a section or step, satisfies the commitment or where the unique formatting method of the procedure does not allow entering a [C] in the left margin or where commitment number is clearly identified.

For those cases where the entire procedure satisfies the commitment, typically identified in the commitment as ALL, the [C] should be placed in the left margin for the PURPOSE section (Section 1.0) and the commitment number identified in the REFERENCES section OR the commitment(s) may be identified by commitment number within a step in the procedure.

Even if the licensee chose not to include the specific commitment number in the area of change in the target document, the commitment number is included in the reference section of the procedure in addition to a permanent marking [C] in the area of change to reflect the area containing the commitment. It ensures that all the regulatory commitments are identified in the target document and can be tracked easily. The NRC staff views this as an improvement of the*

commitment management program Based on the results of the on-site audit, the NRC staff believes that the licensee has implemented the regulatory commitment management program effectively in accordance with UC-105, "Managing 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.

-5 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 CPNPP, Units 1 and 2, is contained in Procedures STA-509 and REG-509. The primary focus of the audit was to ensure that the commitments are implemented without a change and if a change is made, it is in accordance with the approved plant procedures and with the approval of the plant's management. The audit 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 Detailed processes are outlined by which the licensee carries out obligations under its regulatory commitments. Any changes to the commitments are processed through the CMCE process. Changes to obligatory commitments are reported to the NRC in accordance with the recommendations of LlC-105. CMCE identifies the affected commitments, their origin, original criteria, proposed changes, and justification for change. The commitment changes are documented in CMCE forms for submittal to the NRC staff.

The licensee performed an ECTS database search and provided a list of commitment changes made since the last audit. The list contained a total of 79 items, identified as commitment changes. The initial NRC staff review indicated that, with the exception of six items, the remaining of the items were the licensee's internal commitments; therefore, the review was limited to the items related to regulatory commitments only. Further, the review indicated that the licensee search tracked corrections to the ECTS database, not resulting from an actual commitment change, also as commitment changes. The rest of the items fell in this category.

Hence, it was concluded that there were no regulatory commitment changes made by the licensee for this audit period. The completion date for Commitment No. 3641550 was revised.

However, the completion date for this commitment was tied to issuance of the safety evaluation (SE) for WCAP-16793 by NRC staff (90 days after issuance of the SE). The NRC staff had not issued the SE for WCAP-16793 as of the date of this letter. Hence, the change did not require CMCE.

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

3.0 OBSERVATIONS AND RECOMMENDATIONS The ECTS database does not have a field to include the closing date for commitments.

Presently, the licensee is using the field for "Last Update Date" as the date for commitment closure. However, it could potentially be misleading if the ECTS database is revised for any

- 6 other corrections after closing the commitment. The NRC recommended that the ECTS database should include an additional field to clearly state the commitment closing date. The licensee plans to incorporate the recommendation as an enhancement to its commitment management program.

4.0 CONCLUSION

Based on the results of the audit, the NRC staff concludes that the licensee has implemented the regulatory commitment management program effectively, and implemented regulatory commitment changes appropriately, in accordance with LlC-105 and consistent with NEI 99-04.

The specific observations and recommendations identified during the audit are detailed in Section 3.0 of the report.

Note (Applicable to Commitment No. 3618664):

STA-202, Step 2.8.2, requires that for those cases where the entire procedure satisfies the commitment, the [C] designating the entire procedure to satisfy the commitments, should be placed in the left margin for the PURPOSE section (Section 1.0) and the commitment number identified in the REFERENCES section OR the commitment(s} may be identified by commitment number within a step in the procedure. Procedure STA-698 was developed to satisfy this commitment (Commitment No. 3618664). The procedure did not label Section 1.0, "PURPOSE" with [C], as required by Procedure STA-202. However, the Commitment No. was added to the Reference section and the sections of the procedure containing the commitment were labeled with [C] (not the commitment number. The licensee was in the process of creating a condition report to remove the discrepancy.
