Mr. Lawrence J. Weber Senior Vice President and Chief Nuclear Officer UNITED STATES NUCLEAR REGULATORY COMMISSION WASHINGTON, D.C. 20555-0001 July 29, 2015 Indiana Michigan Power Company Nuclear Generation Group One Cook Place Bridgman, Ml 49106
SUBJECT:
DONALD C. COOK NUCLEAR POWER PLANT, UNIT NOS. 1 AND 2 -AUDIT OF THE LICENSEE'S MANAGEMENT OF REGULA TORY COMMITMENTS (TAC NOS. MF6129 AND MF6130)
Dear Mr. Weber:
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 ensure that regulatory commitments are implemented, that changes to the regulatory commitments are evaluated, and when appropriate, reported to the NRC. The NRC's Office of Nuclear Reactor Regulation has instructed its staff to perform an audit of the licensees' commitment management programs once every three years to determine whether the licensees' programs are consistent with the industry guidance in NEI 99-04, and whether regulatory commitments are being effectively implemented.
An audit of the Donald C. Cook Nuclear Plant, Units 1 and 2 (CNP) commitment management program was performed at the plant site on July 15, 16, and 17, 2015. The NRC staff concludes, based on the audit, that Indiana Michigan Power Company (l&M, the licensee) has implemented NRC commitments on a timely basis, and that the licensee has implemented an effective program for managing NRC commitment changes at CNP. The details of the results of the audit are set forth in the enclosed audit report.
L. Weber There is no need for the licensee to respond to this letter. The NRC staff appreciates the resources that were made available by your staff during the audit. If you have any questions, please contact me at (301) 415-2846.

COOK NUCLEAR PLANT. UNITS 1 AND 2 DOCKET NOS. 50-315 AND 50-316
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,"
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 describes a "regulatory commitment" as an explicit statement to take a specific action agreed to, or volunteered by, a licensee by a certain date 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 99-04, and whether regulatory commitments are being effectively implemented.
An audit of the Donald C. Cook Nuclear Plant, Units 1 and 2 (CNP) commitment management program was performed at the plant site on July 15, 16, and 17, 2015. The audit reviewed commitments made, changed, or closed since the previous audit in June 2012 (see audit report dated June 29, 2012; ADAMS Accession No. ML 12178A028).
NRR guidelines direct the 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 (i.e., amendments,
- reliefs, exemptions, etc.) and activities (i.e., bulletins, generic letters, etc.). 2.0 AUDIT PROCEDURE AND RESULTS The audit consisted of three major parts: (1) verification of the licensee's implementation of NRC commitments that have been completed, (2) verification of the licensee's program for managing Enclosure changes to NRC commitments, and (3) verification that all regulatory commitments reviewed were correctly applied in NRC staff licensing action reviews.
2.1 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 (i.e., amendments, exemptions, etc.), or licensing activities (i.e., 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 for verification.
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 and technical specifications.
Fulfillment of these commitments was indicated by the licensee having taken timely action in accordance with the subject requirements.
Procedure PMP-2350-CMS-001, "Commitment Management,"
Revision 8, is the primary procedure for the handling of regulatory commitments.
This procedure contains guidance for the identification,
- tracking, extension, change, and closure of commitment tasks. In addition, it provides a list of the people who are authorized to make regulatory commitments for CNP, as well as guidance for the retention and periodic review of commitments.
The licensee's commitments are tracked in a computer database called the Commitment Management System (CMS). The NRC staff reviewed commitment tracking entries and observed the use of CMS to search for commitments.
The CMS system is unique to CNP. The NRC staff also reviewed the following Data Sheets included in PMP-2350-CMS-001:
- Data Sheet 1, "Commitment Evaluation/Change"
- Data Sheet 2, "Commitment Implementation/Closure Form"
- Data Sheet 3, "Commitment Management Data Input Form" 2.2 Verification of Licensee's Implementation of 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 and 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 that the licensee's CMS 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 -Implementation of Commitments The attached Audit Summary, Table 1, provides details of this portion of the audit and its results.
The NRC staff reviewed the closure documentation for nine closed commitments.
All closed commitments were properly documented using Data Sheet 2, "Commitment Implementation/Closure Form." The NRC staff also reviewed two commitments, numbered 8610 and 8611, that were placed in an "ongoing" status following implementation.
According to PMP-2350-CMS-001, the definition of an ongoing commitment is as follows:
Actions implemented by CNP procedures, instruction,
- policies, or other documents that require continued tracking to maintain compliance.
A commitment that does not have an applicable conclusion and/or closure date; i.e., one requiring a given action on a repetitive basis. Ongoing commitments are reviewed every 3 to 5 years to determine if they should be retained as ongoing or be retired.
The periodic review also ensures that commitments are referenced correctly in implementing documents.
Commitments 8610 and 8611 were placed in an ongoing status using Data Sheet 2, with a note at the bottom specifying that the commitments were not being closed. Overall, the NRC staff concludes that PMP-2350-CMS-001 and the associated commitment management forms used in conjunction with the CMS database constitute an effective program to identify, manage, review, and close commitments made to the NRC as part of licensing actions and activities.
2.3 Verification of Licensee's Program for Managing 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. Accordingly, the NRC staff compared PMP-2350-CMS-001 and Data Sheet 1, "Commitment Evaluation/Change,"
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 audit 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. 2.3.1 Audit Results -Managing Commitment Changes The attached Audit Summary, Table 1, provides details of this portion of the audit and its results.
The NRC staff reviewed the revision documents for four changed commitments.
Each change was evaluated using Data Sheet 1, "Commitment Evaluation/Change,"
to determine whether or not the change could be made through the commitment change process, and whether or not NRC notification was required.
Three of the revised commitments required NRC notification, while one did not. The NRC staff found that PMP-2350-CMS-001 and Data Sheet 1, "Commitment Evaluation/Change,"
follows the guidance of NEI 99-04 closely in regard to managing commitment changes.
The NRC staff observed that the licensee had complete and accurate
- records, and had documented the sampled commitment changes appropriately using Data Sheet 1, "Commitment Evaluation/Change."
The NRC staff observed that overall, the licensee tracking system was effective in documenting the commitment change process, ensuring traceability of commitments, and considering reporting requirements.
2.4 Review to Identify Misapplied Commitments The commitments reviewed for this audit were also evaluated to determine if they had been misapplied.
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 associated with a licensing action. Reliance on an action to support a regulatory decision must be elevated from a regulatory commitment to a legal obligation (e.g., license condition, condition of a relief request, regulatory exemption limitation or condition).
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).
Each of the commitments selected for the audit sample were reviewed to determine if any had been misapplied.
No misapplied commitments were found. 2.4.1 Review of Safety Evaluations for Licensing Actions since the Last Audit In addition to the commitments selected for the audit sample, all license amendment safety evaluations, exemptions, and relief request safety evaluations that have been issued for a facility since the last audit were identified.
These documents were evaluated to determine if they contained any misapplied commitments as described above. No misapplied commitments were found.
3.0 CONCLUSION
The NRC staff concludes, based on this audit, that the licensee has (1) an effective program for managing and implementing regulatory commitments, and (2) an effective program for managing changes to regulatory commitments. 4.0 LICENSEE PERSONNEL CONTACTED FOR THIS AUDIT K.
