1.0 INTRODUCTION

AND BACKGROUND The U.S. Nuclear Regulatory Commission (NRC) informed licensees in Regulatory Issue Summary (RIS) 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), that the Nuclear Energy Institute (NEI) document NEI 99-04, "Guidelines for Managing NRC Commitment Changes" (ADAMS Accession No. ML003680088), contains acceptable guidance for controlling regulatory commitments.

RIS 2000-17 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. 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. 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 and that regulatory commitments are being effectively implemented.

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 (e.g., amendments, reliefs, exemptions) and activities (e.g., bulletins, generic letters).

An audit of the Palo Verde Nuclear Generating Station (PVNGS); Units 1, 2, and 3, commitment management program was performed during November 25 through December 4, 2013. The previous audit of the licensee's commitment management program for PVNGS was documented in an NRC letter to Arizona Public Service Company (APS, the licensee) dated September 23, 2010 (ADAMS Accession No. ML 1 02450675).

2.0 AUDIT PROCEDURE AND RESULTS The audit was performed in accordance with the guidance in NRR Office Instruction LIC-105, Revision 4, "Managing Commitments Made by Licensees to the NRC," dated September 10, 2012 (ADAMS Accession No. ML 12251A203).

The NRC staff reviewed commitments made during the period approximately 3 years prior to the audit (i.e., since the last audit). The audit consisted of three major parts: (1) verification of the Enclosure licensee's implementation of NRC commitments that have been completed; (2) verification of the licensee's program for managing changes to NRC commitments; and (3) verification that all regulatory commitments were correctly applied. 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.

The audit also verifies the licensee's commitment management system includes a mechanism to ensure traceability of commitments following initial implementation.

This ensures that licensee 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. 2.1.1 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, etc.) or licensing activities (bulletins, generic letters, etc.). Before the audit, the NRC staff searched ADAMS for licensee submittals since the last audit and selected a representative sample for verification.

The commitments included in the review are shown in Table 1. The audit excluded the following types of commitments that are internal to licensee processes:

• (1) (2) (3) 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 F_inal 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 Table 1 provides the specific details arid results of the audit for verification of the licensee's implementation of commitments.

The NRC staff found most of the selected commitments to be implemented effectively.

One anomaly was, however, noted by the NRC staff. The NRC staff noted that the commitment number to add an operator action completion time to the Palo Verde Time Critical Action Program was not provided in the license amendment request (LAR) submittal dated August 27, 2010, nor was it identified in the list of open, closed, or changed commitments requested by the project manager during preparation of the triennial commitment audit. Upon further review, 'the licensee noted that Regulatory Commitment Tracking System Action Item (RCTSAI) 3521834 was generated and completed properly to document the commitment; however, it was not traceable through the normal query of the database.

The licensee acknowledged that traceability could be improved and formulated revised correspondence submittal guidance to address this concern prior to conclusion of the commitment audit. All other commitments listed in Table 1 were found to be effectively implemented.

As referenced in the previous NRC audit. of the licensee's commitment management program dated September 23, 2010, the NRC concluded that a commitment concerning NRC Generic Letter 2004:-02, "Potential Impact of Debris Blockage on Emergency Recirculation during Design Basis Accidents at Pressurized-Water Reactors," did not appear to be fully implemented (RCTSAI 2826269).

During the current triennial commitment audit, the NRC staff observed that all three specifications (Specification Nos. 13-MN-301, 13-MN-0163, and 13-MN-0169), were updated to reflect the RCTSAI 2826269. In addition, the NRC staff noted that after the appropriate changes in each specification, the specification is annotated with the following note, "This is an RCTS commitment and shall not be removed o.r changed without prior review by Regulatory Affairs lAW 93DP-OLC08 (Reference RCTSAis 2826264, 2826267, and 2826269)." Therefore, the NRC staff concludes that the commitment is fully implemented and that it adequately designates the change to ensure traceability and future evaluation in accordance with the commitment change control process. 2.2 Verification of the Licensee's Program for Managing Changes to NRC Commitments 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 PVNGS is contained in APS's procedure 93DP-OLC08, Revision 3, "Regulatory Commitment Tracking." The audit reviewed a sample of commitment changes as shown in Table 2 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.

• 2.2.1 Audit Results The NRC staff reviewed the licensee's procedure 93DP-OLC08, Revision 3, against NEI 99-04. Section 1.2 of the procedure references NEI 99-04 in defining the scope of the procedure.

The NRC staff found that the process described in 93DP-OLC08 generally follows the guidance of NEI 99-04 and provides detailed instructions for: (1) making and identifying commitments; (2) tracking commitments; (3) annotating implementing documents to provide traceability of commitments; (4) changing commitments; and (5) periodic reporting of commitment changes. The NRC staff concludes that the procedure used by the licensee to manage commitments prov_ides the necessary attributes for an effective commitment management program. Table 2 provides the specific details and results of the audit of commitment changes for PVNGS. The NRC staff concludes that the licensee effectively processed changes to commitments in accordance with their established procedures and reported the changes to the NRC by annual report or by separate correspondence.

2.3 Verification That All Regulatory Commitments Were Correctly Applied On September 19, 2011, the NRC's Office of the Inspector General (OIG) issued an audit report titled, "Audit of NRC's Management of Licensee Commitments" (ADAMS Accession No. ML 112620529).

The audit identified, in part, that the definition and use of commitments is not consistently understood throughout the NRC. The OIG concluded that this could potentially result in the misapplication of commitments by the NRC staff. A commitment is considered to be misapplied if the action comprising the commitment was relied on by the NRC staff in making a regulatory decision such as a finding of public health and safety in an NRC safety evaluation (SE) associated with a licensing action. A commitment is also considered to have been misapplied if the commitment involves actions that were safety significant (i.e., commitments used to ensure safety). , As one of the corrective actions taken in response to the issues raised in the OIG audit, the NRC staff added further guidance on proper use of regulatory commitments iri NRR Office Instruction LIC-1 01, Revision 4, "License Amendment Review Procedures," dated May 25, 2012 (ADAMS Accession No. ML 113200053).

As stated in Section 4.4.1 of LIC-1 01, NRC staff SEs may rely on a commitment if the commitmentis escalated into an obligation (e.g., a license condition or technical specification requirement) or is subsequently incorporated into a mandated licensing basis document (e.g., Updated Final Safety Analysis Report). In cases where a commitment has been escalated to an obligation or incorporated into a mandated licensing basis document, the "commitment" is no longer considered a commitment and is no longer subject to change via the licensee;s commitment management program since other regulatory processes would govern the change (e.g., Title 10 of the Code of Federal Regulations (10 CFR) 50.90, 10 CFR 50.59). Another corrective action taken in response to the issues raised in the OIG audit included further guidance, concerning performance of commitment audits, being added in Revision 4 of NRR Office Instruction LIC-105, "Managing Commitments Made by Licensees to the NRC," dated September 10, 2012 (ADAMS Accession No. ML 12251A203).

Revision 4 of LIC-105 states that the NRC staff should take the following actions to identify misapplied commitments:

1) Determine if the commitment reviewed involves actions that were safety significant (i.e., commitments used to ensure safety). 2) Determine if the commitment reviewed involves actions that were necessary for approval .. of a proposed licensing action. As discussed in LIC-1 05, the scope of this portion of the audit includes reviewing each of the commitments selected for the audit sample (i.e:., Tables 1 and 2) to determine if any had been misapplied (i.e., per the 2 criteria shown above). In addition, the NRC staff is directed to identify all license amendments, relief requests, and exemptions that have been issued for a facility in the previous 3 years. Table 3 lists each of these documents for PVNGS. The NRC staff is directed to identify all commitments discussed in these documents and evaluate each commitment to determine

• if it has been misapplied based on the 2 criteria discussed above. As provided in Table 3, there were 3 license amendment safety evaluations that discuss regulatory commitments.

All 3 safety evaluations were reviewed and the NRC staff concludes that if necessary, the regulatory commitments were properly escalated to obligations (e.g. license conditions), as discussed in Revision 4 of LIC-1 01, and that the regulatory commitments were not misapplied based on the 2 criteria discussed in Revision 4 of LIC-105.

3.0 CONCLUSION

Based on the above audit, the NRC staff concludes that: (1) the licensee has implemented NRC commitments on a timely basis, and (2) the licensee has implemented an effective program for managing NRC commitment changes. 4.0 LICENSEE PERSONNEL CONTACTED FOR THIS AUDIT Fara Oreshack Robert Roehler Principal Contributor:

In PVNGS, Unit 2's Nine-Month Supplemental (Post-Outage)

Response to NRC Generic Letter 2008-01 (ML 100680520}, the licensee changed the completion date of Commitment No. 21 from 3/31/2010 to 9/30/2010.

The Commitment was to complete evaluation of installing vent valves at three locations in Unit 3 identified by laser templating as being vulnerable to gas accumulation that cannot be easily vented or flushed. Audit Results -Verification of Licensee's Program for Managing Commitment Changes The Regulatory CommitmenUAction Change evaluation summary was reviewed.

The summary states that since the instrument and service breathing air were cross-connected, the breathing air system can no longer be used for breathing air. Therefore, the C02 and 02 monitors downstream of JIAN-P1-0214 are no longer needed. This was evaluated according to Appendix A of 93DP-OLC08.

The Regulatory CommitmenUAction Change evaluation summary was reviewed.

The summary states that an EOF/JIC TAC and a TSC/OSC TAC was implemented.

After a year of run-time, the licensee determined it was more efficient to revise the quorum requirements for the TRG and have the body perform both functions.

This was evaluated according to Appendix A of 93DP-OLC08.

The Regulatory CommitmenUAction Change evaluation summary was reviewed.

The summary states, "Timeframe allows for determination of feasibility and necessity of vent valve installation, and evaluation of programmatic control options." In addition, the vent valve installation was scheduled to be completed by 11/2012, so a 6-month extension to perform feasibility did not impact the implementation schedule .. This was evaluated accordiog tQ Appendix A of 93DP-OLC08.
