UNITED STATES NUCLEAR REGULATORY COMMISSION WASHINGTON, D.C. 20555-0001 April 18, 2014 Mr. Thomas D. Gatlin Vice President, Nuclear Operations South Carolina Electric & Gas Company Virgil C. Summer Nuclear Station Post Office Box 88, Mail Code 800 Jenkinsville, SC 29065 SUBJECT VIRGIL C. SUMMER NUCLEAR STATION-AUDIT OF THE LICENSEE'S MANAGEMENT OF REGULATORY COMMITMENTS (TAC NO. MF2978) Dear Mr. Gatlin: The U.S. Nuclear Regulatory Commission (NRC or the staff) 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, 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. The NRC Office of Nuclear Reactor Regulation has instructed its staff to perform an audit of licensees' commitment management programs periodically to determine whether the licensees' programs are consistent with the industry guidance in NEI 99-04, and that regulatory commitments are being effectively implemented. An audit of Virgil C. Summer Nuclear Station's (VCSNS, licensee) commitment management program was completed in March 2014. The NRC staff concludes that VCSNS has the procedures and processes used to manage commitments consistent with NEI 99-04. However, as detailed in the attached report, the documentation and tracking of these commitments have been inconsistently implemented. In a follow-up audit discussion with the site, the l_icensee intends to make robust changes to their commitment management program to address the programmatic issues identified in the audit. There were no safety issues identified. Details of the audit are set forth in the enclosed audit report. .

T. Gatlin -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, please contact Shawn Williams at (301) 415-1009.

SUMMER NUCLEAR STATION, UNIT 1 DOCKET NO. 50-395 1.0 INTRODUCTION AND BACKGROUND The U.S. Nuclear Regulatory Commission (NRC or the staff) 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 periodically to determine whether the licensees' programs are consistent with the industry guidance in NEI 99-04, and that regulatory commitments are being effectively implemented. An audit of the Virgil C. Summer Nuclear Station's (VCSNS) commitment management program was completed in March 2014. The audit included a staff review of commitments made since the previous audit documented on February 27, 2009 (ADAMS Accession No. ML090570041 ). 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, reliefs, exemptions, etc.) and activities (bulletins, generic letters, etc.). 2.0 AUDIT PROCEDURE AND SCOPE The audit consisted of three major parts: (1) _verification of the licensee's implementation of NRC commitments that have been completed (Section 4.0) Enclosure 1

-2-(2) verification of the licensee's program for managing changes to NRC commitments (Section 5.0) (3) verification that all regulatory commitments reviewed were correctly applied in NRC staff licensing action reviews (Section 6.0)

• The audit addressed a sample of regulatory 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.). Regulatory commitments made in licensee event reports or in response to Notices of Violation may be included in the sample, but the review will be limited to verification of restoration of compliance, not the specific methods used. 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) Non regulatory commitments made on the licensee's own initiative among internal organizational components. (2) Non regulatory 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) Non regulatory commitments made as an internal reminder to take actions to comply with existing regulato_ry requirements such as regulations and Technical Specifications (TSs). Fulfillment of these commitments was indicated by the licensee having taken timely action in accordance with the subject requirements. 3.0 LICENSEE'S REGULATORY COMMITMENT MANAGEMENT PROGRAM The licensee uses the following procedures for managing regulatory commitments: (1) Nuclear Licensing Procedure, NL-1 02, "Processing Regulatory and Industry Documents" (2) Station Administrative Procedure, SAP-999, "Corrective Action Program" (3) Station Administrative Procedure SAP-0630 "Procedure/Commitment Accountability Program" (4) Nuclear Licensing Procedure, NL-121, "Regulatory Commitment Management" The Station Administrative Procedure SAP-0630 "Procedure/Commitment Accountability Program" is the high level overarching procedure for Commitment Accountability Program. NL-121 is the implementation procedure for the site's Commitment Managemknt Program. The licensee's Computerized Maintenance Management System (CMMS) database is used as the primary method to document the implementation of regulatory commitments. The licensee enters each regulatory commitment as a Condition Report (CR) in the CMMS database. The status of the commitments, implementation dates, and associated information including site personnel comments are able to be captured in the CMMS database.

-3 -In addition to tracking regulatory commitments in the CMMS database, the site's Nuclear Licensing Procedure, NL-121, Section 5.4, requires the Licensing department to maintain a "Commitment Log" that includes some basic tracking information for regulatory commitments, including the CR associated with each regulatory commitment. NL-121, Section 5.4, states that the purpose of the Commitment Log is to "ensure recovery of commitment information during future NRC inspections." 4.0 VERIFICATION OF LICENSEE'S IMPLEMENTATION OF REGULATORY COMMITMENTS The purpose of this part of the audit is to: (1) Confirm that the licensee has implemented commitments made to the NRC as part of past licensing actions/activities. (Section 4. 1) (2) For commitments not yet implemented, determine whether the commitments have been captured in an effective program for future implementation. (Section 4.2) (3) Verify that the licensee's commitment management system includes a mechanism to ensure traceability of commitments following initial implementation. This is to ensure 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. (Section 4.3) 4.1 Confirm that the licensee has implemented commitments made to the NRC as part of past licensing actions/activities Per NRR Office Instruction, LIC-1 05 (ADAMS Accession No. ML 13193A358) the staff requested the licensee to provide a list of all open regulatory commitments and a list of closed regulatory commitments that were completed since the last audit on February 27, 2009. The licensee responded by providing their Commitment Log on December 6, 2013. The staff compared the information provided in the Commitment Log to the regulatory commitments that were submitted to the NRC on the docket since the last audit. 4.1.1 Staff Assessment See Enclosure 2, "Regulatory Commitment Management Audit Table" for the staff's detailed assessment and specific deficiencies for each audit sample. In summary, a review of the licensee's Commitment Log identified the following deficiencies:

• Missing open and closed (since the last audit) regulatory commitments (Audit Nos. 3, 10, 16, 17)

• Incorrect status (open vs. closed) of commitments (Audit Nos. 2,11)

• Incorrect due dates for open commitments (Audit No. 1 0)

• The Commitment Log included non-regulatory commitments (Audit Nos. 11, 13) )

-4 -In addition to the above summary, the staff notes that the Commitment Log often does not include fundamental information about the commitment such as. the date the commitment was originally due, any revised due date, the closure date (if applicable), an explanation if the commitment was changed, an explanation if the commitment was identified as "continuous" and now indicates "closed." Including this fundamental information in the Commitment Log would result in a more efficient audit of regulatory commitments and likely reduce the number of deficiencies found. The staff reviewed each CR associated with each audit sample. See the Enclosure 2 for the staff's detailed assessment and specific deficiencies for each audit sample., In summary, a review of the CRs identified the following deficiencies:

• The template CR database contains a "commitment" cell. For regulatory commitments* submitted to the NRC, the licensee often identified it by including "NRC" in the commitment cell on the specific page that the regulatory commitment is discussed in the CR. The staff notes the licensee also uses "Licensing" in the commitment cell to identify internal commitments. The use of the "NRC" identifier in the commitment cell was not a procedure requirement in NL-121, which may have led to the great lack of consistency in using "NRC" to clearly identify NRC regulatory commitment. (Audit Nos. 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 15, 17) .In a follow-up discussion with the licensee, it was determined that the option to choose "NRC" irJ *a dropdown menu of the commitment cell was inadvertently removed from the CMSS software in 2011. The licensee has requested the "NRC" option to be re-added to the commitment cell dropdown.

• Some CRs do not explicitly state anywhere in the CR that it includes a "regulatory commitment." In addition, some CRs do not include the exact or similar wording of the regulatory commitment nor the associated due date as submitted to the NRC. Without the "NRC" identification in the commitment cell, no reference statement to a regulatory commitment, and without including the exact or very similar wording of the regulatory commitment, the staff had difficultly locating the implementation information regarding the regulatory commitment in the CRs. (Audit Nos. '3, 4, 7,' 8, 9, 11, 12, 15)

• For the CRs that included a reference to the regulatory commitment, sor>ne lacked fundamental details such that the staff could not determine the status of the regulatory commitments. (Audit Nos. 5, 6, 14)

• Information in the CR was incorrect. (Audit Nos. 2,11)

• Incorrectly reworded the regulatory commitment in the CR such that the meaning was changed resulting in an incorrect reason for closure. (Audit No. 2)

• 4.1.1.1 Audit No. 2 -Focus Discussion Regarding Two Regulatory Commitments included in the June 9, 2009, "License Amendment Request For Use of Optimized ZIRLOŽ Fuel Rod Cladding." (ADAMS Accession No. ML091620072)

-5-Commitment No. 1: The core reload process for VCSNS will ensure the conditions and lill)itations of the NRC SE for Optimized ZIRLOŽ as addressed in Enclosure are met when a batch of Optimized ZIRLOŽ is implemented.

• Due Date: Continuous, until the contingency requirements of the conditions and limitations have been satisfied. Commitment No.2: SCE&G will confirm that Westinghouse will provide additional ( confirmatory data associated with LTA programs at other facilities prior to subsequent cycles of operation with Optimized ZIRLOŽ fuel rod cladding. Background: Due Date: Continuous, until the LTA data up through the fuel burnup limit applicable for VCSNS has been provided to the NRC. Regulatory commitments No. 1 and No. 2 originated from the staff's Final Safety Evaluation for Addendum 1 to Topical Report WCAP-12610-P-A and CENPD-404-P-A, "Optimized ZIRLOŽII" June 10, 2005 (Optimized ZIRLOŽ Report1). Both regulatory commitments were created to *document the licensee action to ensure Westinghouse provided the required data as outlined in the Conditions and Limitations (Conditions) No.6 and No.7 in the Optimized ZIRLOŽ Report. On February 25, 2013, Westinghouse submitted the final letter to satisfy Conditions No. 6 and No. 7 (ADAMS Accession No. ML 13070A 188). NRC staff has not completed the review of the February 25, 2013 letter, and thus does not consider Conditions No. 6 and No. 7 to be closed. The staff will issue a closeout letter when the review is complete and accepted. The staff further notes that the Conditions in the SE are included in VCSNS licensing basis in TS 6.9.1.11. Therefore, the regulatory commitments are not necessary to ensure compliance with the Conditions. Staff Assessment of Commitment No. 1: Commitment No. 1 was found on Page 5 of the CR. It was appropriately identified as an "NRC" commitment. The licensee closed the regulatory commitment on 8/5/2010. The commitment was inappropriately re-worded in the CR to "VCSNS will use approved methods for the reload design process for VCSNS reloads with Optimized ZIRLOŽ." The staff determined that the rewording of Commitment No. 1 in the CR did not have the same meaning as the original commitment. The licensee closed Commitment No. 1 based on the following reason per the CR: "Design Engineering satisfies commitment 1 by using the Westinghouse core design computer codes and the Westinghouse METCOM methodology for the reload design process. The 1 Letter from H. N. Berkow, NRC, to J. A. Gresham, Westinghouse Electric Company, Final Safety Evaluation for Addendum 1 to Topical Report WCAP-12610-P-A and CENPD-404-P-A, "Optimized ZIRLOŽ" June 10, 2005. ADAMS Accession No. ML051670403. Non-Proprietary SE: ML051670408

/ ' -6-Westinghouse design tools are NRC-approved methods and computer codes." o The reason provided does not address the original commitment. The licensee's rewording of the original commitment apparently caused a misunderstanding of the requirements needed to close the commitment. The reason provided in the CR does not address the original commitment. o The licensee incorrectly closed Commitment No. 1, on August 5, 2010. The data to satisfy Commitment No. 1, and thus close out Conditions No. 6 and 7 of the Optimized ZIRLOŽ Report SE, was not provided to the NRC until February 24, 2013. o In a follow-up discussion with the licensee, the licensee provided that the commitment continues to be implemented as part of the reload analysis (an existing program). Staff Assessment of Commitment No. 2 Commitment No. 2 was found on Page 5 of the CR. It was appropriately identified as an "NRC" commitment. The licensee closed the regulatory commitment on August 5, 2010. The CR provided the following reason for closure: "Westinghouse completed commitment 2 by submitting a report to the NRC for three cycles of operation data for Opt Zirlo clad fuel. The submittal was documented in the Westinghouse letter NF-CG-10-58, dated July 29, 2010, Mr. R. W. Kerr to Mr. W. M. Herwig." ( o The reference letter in the CR appears to be incorrect as the staff could not locate it after performing an extensive ADAMS search. However, an ADAMS search identified a Westinghouse submittal dated July 26, 2010, SER Compliance of WCAP-12610-P-A & CENPD-404-P-A Addendum 1-A "Optimized ZIRLOŽ" (ADAMS PKG No._ML 1 02140223) that may have been the intended reference. o The licensee incorrectly closed Commitment No. 2 on August 5, 2010. The data to satisfy Commitment No. 2, and thus close out Conditions No. 6 and 7 of the Optimized ZIRLOŽ Report SE, were not provided to the NRC until February 24, 2013. Commitments No. 1 and No. 2 should either be: Reopened and not closed until the staff issues a final closeout letter to Westinghouse acknowledging that Conditions 6 and 7 of the Optimized ZIRLOŽ SE have been met.; or Closed based on the regulatory commitments are included in VCSNS licensing basis in TS 6.9.1.11. Page 6-16a, f. requires compliance with WCAP-1261 0-P-A and CENPD-404-P-A, Addendum 1-A, "Optimized ZIRLOŽ ," July 2006, which includes the staff's SE requiring Conditions 6 and 7, and thus Commitment No. 1 and No.2 to be met.

-7 -In a follow-up discussion with the licensee, the licensee committed to reopen both commitments until the staff issues a final closeout letter to Westinghouse acknowledging that Conditions 6 and 7 of the Optimized ZIRLOŽ SE have been met. 4.1.2 Conclusion The primary purpose of Section 4.1 of this audit is to review the documentation associated with a sampling of regulatory commitments. In general, the commitment management documentation was insufficient. A summary is provided in Attachment 1. Specific details are provided in Enclosure 2. 4.2 For commitments not yet implemented, determine whether the commitments have been* captured in an effective program for future implementation The staff reviewed the CRs associated with the open regulatory commitments to determine if they have been captured in an effective program for future implementation. 4.2.1 Staff Assessment and Conclusion See Enclosure 2 for specific details. A summary is provided below. Audit: No.2: No.3: No.5: No. 10: The commitment documentation was insufficient as explained in Section 4.1.1.1 of this audit. The commitment documentation was insufficient. The staff was not able to locate the three security-related commitments i_n the CR that was referenced in the Commitment Log. In a follow-up discussion with the licensee, the licensee determined that although the commitments as provided to the NRC were not written clearly in the CR, the actions to implement the commitments were captured in the CR and are now closed. The commitment was not implemented by the original due date. Approximately nine months after the commitment due date, the licensee self-identified the missed commitment and opened a new CR. Upon reviewing the new CR, the staff could not determine the new due date to complete the regulatory commitment; thus, staff concludes the commitment documentation was insufficient. In a follow-up discussion with the licensee, the licensee provided that the commitment is expected to be implemented in the second quarter of 2014. Although there are documentation issues explained in the enclosure, the staff concludes the two remaining open commitments are captured in an effective program for future implementation. *

-8-No. 12: Although there are documentation issues explained in the enclosure, the staff concludes the open commitments are captured in an effective program for future implementation. No. 15: The commitment documentation was insufficient. The staff could not locate the open Commitment No. 1 in the CR referenced in the Commitment Log. In a follow-up discussion with the licensee, the licensee stated that they will enter the commitment in a CR. No. 17: The commitment documentation was insufficient. The staff could not locate Commitment Nos. 1, 3, 4, 5, 6, 7, 8, 9, and 12 in the referenced CAs. In a follow-up discussion with the licensee, the licensee stated that they will enter the commitments in a CR. 4.3 Verify that the licensee's commitment management system includes a mechanism to ensure traceability of commitments following initial implementation 4.3.1 Staff Assessment The staff verified that the licensee's commitrnemt management system includes a mechanism to ensure traceability of commitments following initial implementation. Procedure NL-121, Revision 6, Section 6.1.1 requires marking plant procedures with a "C" code that were revised in response to a regulatory commitment. Section 6.1.2 requires an independent verification from the "Unit Evaluator" to ensure that the revision met the intent of the commitment made to the regulator and that the associated markings were properly applied. 4.3.2 Conclusion Based on the guidance in NL-121, the staff concludes that the 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. 5.0 VERIFICATION OF THE LICENSEE'S PROGRAM FOR MANAGING NRC

• COMMITMENT CHANGES The purpose of this part of the audit is to: (1) Verify that the licensee has established administrative controls for modifying or deleting commitments made to the NRC. (Section 5.1) * (2) Review a sample of regulatory commitment changes that included changes that were or will be reported to the NRC. (Section 5.2) (3) Review of changes that were not or will not be reported to the NRC. (Section 5.3)

-9 -The audit included a review of the documentation of regulatory commitments that were changed from the originally submitted commitments. The staff evaluated the change to ensure it was completed in accordance with the licensee's procedures, that the licensee's technical evaluations adequately justify the change, and that the NRC was informed of the change, as *appropriate. The staff primarily used the guidance in NL-121, Section 6.2, to audit this section. 5.1 Verify that the licensee has established administrative controls for modifying or deleting commitments made to the NRC 5.1.2 Staff Assessment NL-121 is the licensee's implementation procedure that establishes administrative controls for modifying or deleting commitments made to the NRC. The staff performed a comparison to the NRC endorsed NEI 99-04, "Guidelines for Managing NRC Commitment Changes" to the guidance in NL-121. Key comparisons include:

• NEI 99-04, Figure A-1, "Commitment Management Change Process" is identical to Nt-121, Enclosure A, "Commitment Change Process."

• NEI. 99-04, Figure A-2, "Safety Significance Assessment" is identical to NL-121, Enclosure B, "Safety Significance Assessment."

• NEI 99-04, Figure A-3, "Commitment Evaluation Summary" is near identical to NL-121, Attachment Ill, "Commitment Change Evaluation Worksheet." 5.1.3 Conclusion The staff concludes the licensee has established administrative controls consistent with NEI 99-04 for modifying or deleting commitments made to the NRC. 5.2 Review a sample of regul9-tory commitment changes that included changes that were or will be reported to the NRC.

• According to the licensee's NL-121 procedure, there are two types of licensee documents that report a change to a regulatory commitment to the NRC: (1) Annual Commitment Change Summary Report (Annual Report) referenced in NL-121, Section 5.2.3 and Enclosure A, Decision Step 5. (2) Timely Notification of an Intended Change to a Regulatory Commitment letter. NL-121, Enclosure A, Decisions Step 3 and 4, require a timely notification of the change to a regulatory commitment. 5.2.1 Staff Assessment Annual Report Accordi.ng to NL-121, Enclosure A, the licensee is required to submit the following in an Annual Report to the NRC:

-10-any change to a regulatory commitment that has already been implemented that the NRC relied upon the regulatory commitment in a safety evaluation to conclude a reasonable assurance finding 1 any change to a regulatory commitment that minimizes a reoccurring adverse condition for which the change was specifically to minimize recurrence of the adverse condition During the time frame of the audit, the licensee submitted the following Annual Reports: a) 2009 -February 18, 2010 (ML 1 00541576) b) 2010-April 5, 2011 (ML 11 0960592) c) 2011 and 2012-Annual Reports were not submitted because there were no changes to regulatory commitments that met the requirements for the Annual Report. The staff questioned the licensee regarding the missing 2011 and 2012 Annual Reports. The licensee responded that the requirement has been interpreted to only require an Annual Report if there were any changes that met the reportable criteria. In response to the staff's question, the licensee submitted a revision to the NL-121, step 5.2.3, to add "If no commitment reductions are performed, no report is required to be sent." The licensee confirmed that Annual Reports 2011 and 2012 were not submitted because there

• were no changes that met the reportable criteria. Timely Notification of an Intended Change to a Regulatory Commitment (Timely Notification Letter) According to NL-121, Enclosure A, the licensee is required to submit a Timely Notification Letter for an anticipated change to a regulatory commitment that the NRC relied upon in a safety evaluation to conclude a reasOnable assurance finding. 1 During the time frame of the audit, the licensee submitted one Timely Notification Letter on May 13,2013, (ML13142A142). Audit Samples:* Audit Nos. 14 and No. 16 were the only two regulatory commitments that were changed and subsequently reported to the NRC during the time frame of the audit. The staff requested and reviewed the documentation associated with the evaluation required in NL-121, Section 6.2.1 0 "Commitment Change Development" and Attachment Ill, "Commitment Change Evaluation Worksheet." No deficiencies were noted. 1 OIG Audit report OIG-11-A-17, "memorandum from S. Dingbaum (OIG) toW. Borchardt (NRC) dated September 19, 2011, (ADAMS Accession No. ML 112620529) found that the staff has misapplied regulatory commitments in safety evaluations in the past. Going forward, the staff will no longer rely on a regulatory commitment to make a reasonable assurance finding.

-11 -5.2.2 Conclusion For the regulatory commitment changes that were reported to the NRC, the staff concludes that they were evaluated in accordance with licensee's programs and procedures and that the l technical evaluations adequately justified the change.

• 5.3 Changes to Regulatory Commitment that were Not Reported to the NRC 5.3.1 Staff Assessment and Conclusion During the time frame of the audit, there were no changes to regulatory commitments that were not reported to the NRC; therefore, the staff could not audit this section. 6.0 REVIEW OF SAFETY EVALUATION REPORTS FOR LICENSING ACTIONS SINCE THE LAST AUIDT TO DETERMINE IF THEY ARE PROPERLY CAPTURED AS COMMITMENTS OR OBLIGATIONS Review to Identify Misapplied Regulatory Commitments The commitments reviewed for this audit were also evaluated to determine if they had been misapplied. A regulatory 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 regulatory 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. In addition to the commitments selected for the audit sample, all license amendment safety evaluations, exemptions and relief request safety evaluations (SE) that have been issued for V :c. Summer from February 1, 2009, to November 30, 2013, were evaluated to determine if they contained any misapplied commitments as described above. 6.1 Staff Assessment License Amendments: 1) Amendment No. 181 dated June 9, 2009 (ADAMS Accession No. ML091210666) *Audit No. 1. The staff identified a misapplied commitment in the SE. The SE stated: "The staff considered the licensee's commitment to implement 10 CFR Part 26, Subpart I concurrently with the deletion of TS work hour requirements in its evaluation of the proposed change. Given the licensee's commitment, there is reasonable assurance that the licensee will comply with the regulations for work hour controls, either through TS I '

-12-requirements or through the requirements of 10 CFR Part 26, Subpart /, at all times at VCSNS." The regulatory commitment was met and closed on October 1, 2009. Upon re-reviewing the regulatory commitment submitted and consulting with the technical reviewers who misapplied the commitment in the SE, it has been determined, in retrospect, that the regulatory commitment was not needed for a reasonable assurance finding. The regulatory commitment is a commitment to comply with the existing regulatory requirement or the TSs requirements regarding work hour controls. No further follow-up is necessary.

Conclusion Regarding Section 6.0 of the Audit, the staff identified one misapplied commitment. The commitment has been adequately implemented and is now closed. The staff determined that, in retrospect, the regulatory commitment was not needed for a reasonable assurance finding. No further follow-up is necessary. 7.0 OBSERVATIONS AND RECOMMENDATIONS 7.1 Previous Audit Observations and Recommendations The staff included the following recommendations in the last audit completed on February 27, 2009. Below is staff's assessment of implementation, if any, of the recommendations from the last audit: (1) " ... consider conducting an internal audit of the NRC regulatory commitments and establish a frequency of future internal audits ... " Staff Assessment: The staff did not identify any reference that requires a self-assessment of the commitment management program in NL-121; however, the licensee provided that an internal audit was conducted in May 2012. The staff suggests revising NL-121 to include. an internal audit requirement and frequency. (2) "given that there is not a dedicated database to NRC regulatory commitments, compiling a repository of NRC regulatory commitments would address the seemingly burdensome task of searching the entire CR database for NRC regulatory commitments once every 3 years to support the NRC audit." Staff Assessment: NL-121, Section 5.4, seems to address this recommendation as it requires a Commitment Log to be maintained by the Licensing Technician to ensure easy recovery of commitment information during future NRC inspections. (3) "ensure CR actions are appropriately flagged as "NRC regulatory commitments" if applicable" Staff Assessment: Based on the numerous deficiencies identified in Enclosure 1, "Regulatory Commitment Management Audit Table," the staff concludes this recommendation has not been implemented.

-15-7.2 Audit Observations and Recommendations (1) Observation: The Commitment Log was generally insufficient. It lacked the fundamental information about each commitment such as: the date the commitment was originally due a revised due date, if applicable a closure date, if applicable if the commitment was changed from the original commitment if an NL-121, Attachment Ill, "Commitment Change Evaluation Worksheet" was completed There were also open commitments in the Commitment Log for which the due date was past due for completion. There was no additional information provided regarding the reason that the commitment is past due and what is the new expected commitment completion date. Including this fundamental information in the Commitment Log would allow site personal and NRC staff to more efficiently audit and confirm that the regulatory commitments were completed per the original due dates without going through the timely and burdensome effort of reviewing each CR associated with each regulatory commitment. Recommendation: Include fundamental information regarding the regulatory commitments in the Commitment Log as indicated in the observation above. (2) Observation: Generally, the CRs lacked clear identification that it contained regulatory . commitments as described in the audit report Section 4.1.1. Recommendation: Consistently use the identifier "NRC" in the commitment cell of the associated CR. In the description, explicitly state that the corrective action is a regulatory commitment and include the exact wording of the regulatory commitment that was submitted to the NRC. (3) Observation: . Some CRs lacked fundamental information regarding the status and implementation of the commitments. Recommendation: Establish clear guidelines on the type of information and implementation records that should be included in the CR for regulatory commitments. CR should include references to the following implementation records: Procedure revisions Completed Work orders and/or plant walkcfowns Plant design calculations Plant drawings Issued memorandums Initiated licensing actions NL-121, Attachment Ill, "Commitment Change Evaluation Worksheet"

-16-/ (4) The Licensee's submittal dated August 30, 2012 (ADAMS Accession No. ML 12248A270) contained a new regulatory table not submitted previously that included a separate column to identify if the regulatory commitment was a one-time action or a continuous commitment. Recommendation: Adopt this good practice for future submittals of regulatory commitments. (5) Observation: NL-121, Section 7.2.1 states, "Commitment change documentation maybe retained by NL as historical information." The staff notes that the commitment change documentation is a primary focus for this audit and will be requested during all commitment management program audits. Recommendation: Revise this statement to indicate that the commitment change documentation shall be retained for auditing purposes and, if applicable, clearly state in the Commitment Log and CR that an NL-121 Attachment Ill was completed for any change to the commitment. (6) Observation:-The staff notes there were many regulatory commitments submitted that set an implementation period for an amendment (Audit Nos. 1, 4, 7). The staff notes that these types of regulatory commitments are more appropriately licensee internal commitments. Upon the issuance of an amendment, the NRC establishes the timeliness requirement for the licensee to implement the amendment. The staff notes that in the more recent LARs, VCSNS has put the request for an implementation'period more appropriately in the cover letter. Recommendation: The staff suggests reevaluating the licensee's criteria used to determine the threshold of whether an item should be a regulatory commitment or a licensee internal commitment. 8.0 CONCLUSION The NRC staff concludes that VCSNS has the procedures and processes used to manage commitments consistent with NEI 99-04. However, the documentation and tracking of the commitments have been inconsistently implemented. Key improvements that are needed are to improve the documentation and implementation details associated with regulatory commitments. 9.0 LICENSEE PERSONNEL CONTACTED FOR THIS AUDIT Renard Perry John Garza Principal Contributor: Shawn Williams Date: April 18, 2014 Attachment: Summary of Audit Results Summary of Audit Results Audit Sample: No. 1: The commitment was adequately implemented. No. 2: The commitment documentation was insufficient as explained in Section 4.1.1.1. No. 3: The commitment documentation was insufficient. The staff was not able to locate the three security related commitments in the CR that was referenced in the Commitment Log. No. 4: The commitment was adequately implemented: No. 5: The commitment was not implemented by the original due date. Approximately nine months after the commitment due date, the licensee self-identified the missed commitment and opened a new CR. Upon reviewing the new CR, the staff could not determine the new due date to complete the regulatory commitment thus, staff concludes the commitment documentation was insufficient. No. 6: The commitment documentation was insufficient. The staff could not locate the closure dates of the three commitments or information related to how the original "continuous" commitments were changed to "closed." No. 7: The commitment was adequately implemented. No. 8: The CR did not contain the commitment as written. however, the staff can conclude based on the last page of the CR, that the commitment was implemented within the time frame. No. 9: The commitment documentation was insufficient. The staff could not locate the commitments in the CR referenced in the Commitment Log. No. 1 0: Although there are documentation issues explained in the enclosure, the staff concludes the two remaining open commitments are captured in an effective program for future implementation. No. 11: This audit sample was incorrectly included in the licensee's Commitment Log as a regulatory commitment. It was never submitted as a regulatory commitment. The staff further notes the Commitment Log and the CR incorrectly identifies the licensee's internal commitment as "open" contrary to a letter dated May 16, 2013, that indicates the internal commitment is closed. No. 12: Although there are documentation issues explained in the enclosure, the staff concludes the open commitments are captured in an effective program for future implementation. Attachment

-2 -No. 13: This audit sample was incorrectly included in the licensee's Commitment Log as a regulatory commitment. It was never submitted as a regulatory commitment. No. 14: The commitment documentation was insufficient. The documentation did not include an explanation of why the commitment was closed when only the frequency of the commitment was changed. No. 15: The commitment documentation was insufficient. The staff could not locate the open Commitment No. 1 in the CR referenced in the Commitment Log. No. 16: The commitment was adequately implemented and closed. No. 17: The commitment documentation was insufficient. The staff could not locate Commitment Nos. 1, 3, 4, 5, 6, 7, 8, 9, and 12 in the referenced CRs.
