DUANE ARNOLD ENERGY CENTER - AUDIT OF THE LICENSEE'S MANAGEMENT OF REGULATORY COMMITMENTS (TAC NO. ME6730)

Dear Mr. Anderson:

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 Duane Arnold Energy Center (DAEC) commitment management program was performed at the plant site on October 11, 2011. The NRC staff concludes, based on the audit, that (1) NEXTERA Energy Duane Arnold, 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 DAEC. The details of the audit are set forth in the enclosed audit report.

- 2 The NRC staff appreciates the resources that were made available by your staff, both before and during the audit. If there are any questions, I can be contacted at (301) 415-3079.

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, 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 Duane Arnold Energy Center (DAEC) commitment management program was performed at the plant site on October 11, 2011. The audit reviewed commitments made since the previous audit on October 30 and 31,2008, which was documented as an Audit Report dated December 18, 2008, and is publically available electronically from the Agencywide Documents Access and Management System (ADAMS) using the ADAMS Accession No. ML083460261. 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.

Enclosure

- 2 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.). Also included in the population to provide the sample were commitments from the License Renewal activity. Commitments made in Licensee Event Reports or in response to Notices of Violation could be included in the sample, but the review is limited to verification of restoration of compliance, not the specific methods used. Before the audit, the NRC staff searched the ADAMS for the licensee's submittals since the last audit and selected a representative sample population of regulatory commitments for verification as the scope of the audit.

The examination of license amendments yielded the following results (Except where noted the commitment, if any, was stated in the application letter):

  • Zero commitments for Amendments 272, 273, 275, 276 One commitment for Amendment 271, 274
  • Two commitments for Amendment 277
  • Multiple commitments to implementation milestones for Amendment 278 (cyber security application Enclosure 2 and in supplement dated September 27,2010)

A request for additional information (RAI) was assembled for the licensee to locate documentation for regulatory commitments within the scope of the audit. That RAI was sent August 1, 2011 (ADAMS Accession No. Ml11214A006).

Excluded from the scope of the audit was Amendment No. 279, issued on September 8, 2011, within the interval prior to the site visit, but after the date of the RAI. Given the other sources of potential samples, the selected sample population remained representative of the population to be managed without inclusion of Amendment No. 279. Further, Amendment No. 279 did not contain any commitments. Also, the licensing action request (LAR) that became Amendment No. 280 did not contain any commitments. However, the LAR that became Amendment No. 281, dated June 1,2012 contained one commitment in its application letter NG-11-0117, dated May 31,2011. letter NG-11-0117 was used as a known open commitment, as of September, 2011.

Based on the RAI the licensee assembled a responsive set of documents for the site visit and computer network access. Qualified DAEC staff supported the audit.

- 3 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 Regulatory Commitment Management Process Description and Audit Results During the period of interest for this audit NextEra Energy Duane Arnold, LLC (the licensee) applied Administrative Control Procedure (ACP) 102.2, "Action Request System," which identifies the methods and site organization tools for managing development, review, and implementation of station commitments. The licensee's Procedure ACP 114.5, "Procedure for Evaluation of NRC Commitment Changes,"

established 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.

On May 1,2009 the licensee deleted ACP 114.5 and adopted [FPL] Fleet Procedure PI-AA-205, dated July 31, 2008. Thus, the licensee experienced a transition between established local procedures and adopted fleet procedures. This presented the NRC auditor with an opportunity to probe the success of licensee management of its regulatory commitments as well as its success in managing changes to processes.

Under ACP 102.2 an Action Request System (ARS) database identified as "TeamTrack" was used in conjunction with other information sources to address and track regulatory commitments.

The licensee's successor database is NAMS, which performs the same function under the updated fleet procedures. Each plant in the fleet will have separately identified regulatory 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., plant procedures, examination records, and/or other plant documentation).

Hard copies of documents were available. In addition, the audit was facilitated by the use of electronic versions of documents to be verified. The NRC reviewed the documents and summarized the selected commitment information in the attachment to this audit report.

- 4 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 that 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 ACP and ARS described in the licensee's procedures ACP 102.2 and ACP 114.S and its successor PI-AA-20S, provide acceptable tools for the licensee to capture and implement the NRC guidance on commitment management programs.

In its process the licensee enters the regulatory commitments made to the NRC into a database. The regulatory commitments are labeled as NRC commitments. Each commitment is numbered and described by a commitment title and brief description. A database is populated with information pertaining to the status of the commitments, implementation dates, identification of the target documents (that is. those documents that will finally capture the commitment), and relevant comments.

The licensee's staff is well trained in updating the commitments management program.

The auditor verified that a sufficient number of the licensee's staff had routine access and retained the knowledge to maintain the process. Thus, there is negligible risk to process integrity due to planned personnel absences or to personnel turnover.

The NRC staffs audit of the licensee's commitment management program for DAEC did not identify any regulatory commitments that were not satisfied or not incorporated. The licensee has adequately maintained the database, and all the commitments selected for this audit were easily traceable. In case the commitment was already incorporated, the database provided an accurate status of the commitment and provided reference to the implementing document.

In its self assessment completed at the end of September, 2011, the licensee examined whether the conversion to NAMS introduced any failure to track regulatory commitments attributable to the transition to NAMS. It did not. As an observation the NRC auditor compliments the licensee on timing its self assessment to just prior to the NRC audit and addressing any risk to regulatory commitment management induced by the NAMS conversion.

To ensure that the regulatory commitments are not removed/changed in future revisions to the target documents, the licensee's process includes a database search to identify all the open and closed commitments against the document/procedure being revised, to ensure that all the closed commitments are captured. Further, the process ensures that the commitments are neither removed nor changed without management approval, in accordance with the plant procedures.

As part of the regulatory commitment process, the target document contains identifiers for edits attributable to regulatory commitments, to ensure that future writers and editors do not undo any completed regulatory commitments.

- 5 The governing procedure for managing the documents remains ACP 106.1, after adoption of NAMS. Use of ACP 106.1 provides continuity for procedure formats and accommodates adoption of FPL (the Parent Company of the licensee) style guides along with DAEC style guides. In response to NRC auditor questions probing for vulnerabilities, the licensee stated that they had not experienced any document failures assignable to incompatible style guides.

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 LlC-105, "Managing Regulatory Commitments Made by Licensees to the NRC," and consistent with NEI 99-04.

The processes, as documented, appear robust to manage regulatory commitments and minimize vulnerabilities associated with document management in general, transitions to successor processes, anticipated contacts by future staff or contract writers and editors, and employment turnover of process support personnel. Further, the licensee is routinely assessing process performance and receives validating information on its ongoing success.

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 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 DAEC is contained in procedures ACP 102.2, ACP 114.5 and its successor PI-AA-205 and its secondary procedures. 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 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.

2.2.1 Audit Results Detailed processes are outlined by which the licensee carries out obligations under its regulatory commitments. Any changes to the commitments were processed through the ARS (TeamTrack) process before May 2010 and through NAMS thereafter. Changes to obligatory commitments are reported to the NRC in accordance with the recommendations of NEI 99-04. ARS and NAMS identify the affected commitments, their origin, original

- 6 criteria, proposed changes, and the justification for change. The commitment changes are documented in ARS forms for submittal to the NRC staff.

Five commitment changes were reviewed during the audit, from identification, through evaluation to disposition. The dispositions made of the four changes that were not reportable were as follows: Three items were changed to a deleted status; one item was left in its original form but reference to it was deleted. One commitment change (CR01621 097) was identified and assessed during the audit as requiring notification to the NRC. Licensee records stated that notification was made by Letter NG-11-0201 dated June 8, 2011. This information was verified by search in ADAMS, which yielded ML111590889 as the cited document. The information in the report to the NRC was consistent with the information processed by the licensee.

The summarized results from the five items were:

Commitment Change No.

Nature of the change reason for change NRC Notification, per evaluation CA050256 COM036481 COM044056 Deleted for reasons provided on each evaluation sheet such as assurance of the action provided by procedural steps; not needed for operability; improved training programs accomplished goals of commitment.

Not required ECP 1895 EC 156088 Commitment retained. but removed as a reference since no longer needed in the target procedure.

Not required CR01621097 Delay scheduled testing until after planned replacement equipment is installed.

Yes - Notification sent as NG-11 0201 dated June 8. 2011 and docketed as ML111590889. as part of Report of Facility Changes, Tests and Experiments, Fire Plan Changes, and Commitment Changes In all cases the disposition of reviewed items reflected the evaluations. All records appeared to be complete and properly reviewed and authorized. Based on signature dates items moved through the evaluation process without undue delay. Based on the results of the on-site audit, the NRC auditor believes the licensee has implemented regulatory commitment changes appropriately, consistent with NEI 99-04.

3.0 OBSERVATIONS AND RECOMMENDATIONS The auditor noted that the information requested to be on hand at the start of the audit was efficiently provided and well organized. Assigned licensee personnel were efficient and effective in supporting the audit. There are no observations leading to recommendations for change.

4.0 CONCLUSION

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