By letter dated March 26, 2014 (ADAMS Accession No. ML 14083A620), the NRC notified all licensees and construction permit holders that the staff is conducting audits of their responses to Order EA-12-051 1n accordance with NRC Office of Nuclear Reactor Regulation Office Instruction LIC-111, "Regulatory Audits" (ADAMS Accession No. ML082900195). The purpose of the staff's audit is to determine the extent to which the licensees are proceeding on a path towards successful implementation of the actions needed to achieve full compliance with the order.
S. Capps -2-The ongoing audit process, to include in-office and onsite portions, allows the staff to assess whether it has enough information to make an Integrated Plan safety evaluation. The audit allows the staff to review additional information provided following issuance of the ISE, supplements to the licensee's integrated plan, implementation design aspects and feasibility, and other audit questions. Additionally, the staff gains a better understanding of submitted information, identifies additional information necessary for the licensee to supplement its plan, and identifies any staff potential concerns. This document outlines the onsite, licensee audit process that will provide the NRC staff more detailed understanding of the licensee's implementation strategy and determine if further information is needed to make a safety determination. The staff plans to conduct an onsite audit of specific aspects of the MNS OIP, as supplemented, at the licensee's vendor facility in accordance with the enclosed audit plan from May 6-7, 2014. If you have any questions, please contact me at 301-415-2901 or by e-mail at john.boska@ nrc.gov. Docket Nos.: 50-369 and 50-370 Enclosures: 1. Audit plan 2.

McGuire Nuclear Station, Units 1 and 2 BACKGROUND AND AUDIT BASIS On March 12, 2012, the U.S. Nuclear Regulatory Commission (NRC) issued Order EA-12-051, "Issuance of Order to Modify Licenses with Regard to Reliable Spent Fuel Pool Instrumentation" (Agencywide Documents Access and Management System (ADAMS) Accession No. ML 12054A679), to all power reactor licensees and holders of construction permits in active or deferred status. The order requires, in part, that all operating reactor sites have a reliable means of remotely monitoring wide-range Spent Fuel Pool (SFP) levels to support effective prioritization of event mitigation and recovery actions in the event of a beyond-design-basis external event.

By letter dated February 28, 2013 (ADAMS Accession No. ML 13086A095), as supplemented by letters dated July 11, 2013 (ADAMS Accession No. ML 13197A409), August 26, 2013 (ADAMS Accession No. ML 13242A009), and February 27, 2014 (ADAMS Accession No. ML 14073A467), Duke Energy Carolinas, LLC (Duke Energy) submitted its OIP for William B. McGuire Nuclear Station (McGuire or MNS), Units 1 and 2, describing how it will achieve compliance with Attachment 2 of Order EA-12-51 by fall 2014 for Unit 1 and fall 2015 for Unit 2. The NRC staff's review led to the issuance of the McGuire interim staff evaluation (ISE) and request for additional information (RAI) dated October 28, 2013 (ADAMS Accession No. ML 13281 A791) and as corrected on November 7, 2013 and December 20, 2013 (ADAMS Accession Nos. ML 13309A782 and ML 13353A 142 respectively). By letter dated March 26, 2014 (ADAMS Accession No. ML 14083A620), the NRC notified all licensees and construction permit holders that the staff is conducting audits of their responses to Order EA-12-051 in accordance with NRC Office of Nuclear Reactor Regulation (NRR) Office Instruction LIC-111, "Regulatory Audits" (ADAMS Accession No. ML082900195). The purpose of the staff's audit is to determine the extent to which the licensees are proceeding on a path towards successful implementation of the actions needed to achieve full compliance with the order. The ongoing audit process, to include in-office and onsite portions, allows the staff to assess whether it has enough information to make an Integrated Plan safety evaluation. The audit allows the staff to review additional information provided following issuance of the ISE, supplements to the licensee's integrated plan, implementation design aspects and feasibility, and other audit questions. Additionally, the staff gains a better understanding of submitted information, identifies additional information necessary for the licensee to supplement its plan, and identifies any staff potential concerns. This document outlines the onsite, licensee audit process that will provide the NRC staff more detailed understanding of specific aspects of the MNS OIP, as supplemented, at the licensee's vendor facility and determine if further information is needed to make a safety determination. Enclosure 1
-2-During the review of the MNS OIP, the licensee identified that AREVA was selected as the vendor providing the SFP Level instrumentation. As part of the NRC staff's ongoing audit and review of the MNS OIP, the NRC staff will conduct this audit at the licensee's vendor facility, per the audit process described above, to review information concerning the design features of the AREVA SFP Level instrumentation as it pertains to the MNS plan with an awareness that the AREVA design may have generic applicability and be utilized in other licensees' site specific SFPI implementation. Following the licensee's declaration of order compliance, the NRC staff will evaluate the OIP as supplemented, and, as appropriate, other licensee submittals based on the requirements in Order EA-12-051. The staff will make a safety determination regarding order compliance using the Nuclear Energy Institute (NEI) developed guidance document NEI 12-02, "Industry Guidance for Compliance with NRC Order EA-12-051, "To Modify Licenses with Regard to Reliable Spent Fuel Pool Instrumentation" (ADAMS Accession No. ML 12240A307), as endorsed, with exceptions and clarifications, by NRC interim staff guidance (ISG) JLD-ISG-2012-03 "Compliance with Order EA-12-051, 'Reliable Spent Fuel Pool Instrumentation"' (ADAMS Accession No. ML 12221 A339) as providing one acceptable means of meeting the order requirements. Other methods that deviate from the guidance may be found acceptable, but will require additional staff review and attention. AUDIT SCOPE As discussed, onsite audits will be performed per NRR Office Instruction LIC-111, "Regulatory Audits," to support the development of safety evaluations. The purpose of the NRC audit is to provide the NRC staff a more detailed understanding of specific aspects of the MNS OIP, as supplemented, at the licensee's vendor facility, review the licensee's vendor design information concerning the AREVA SFP Level instrumentation, and determine if further information is needed to make a safety determination. This onsite audit has two primary purposes: (1) Review the licensee's AREVA SFP Level instrumentation design specification and test results information that are anticipated to be provided in response to the NRC staff's RAis, and (2) Confirm NRC staff understanding of the installation requirements, operation, and required maintenance of the licensee's AREVA SFP Level instrumentation. The NRC staff will conduct an evaluation of the licensee's vendor and design information that addresses the topics in the enclosed generic design information template. The NRC audit team requests for the licensee to arrange for a presentation on the vendor's SFP Level instrumentation design per the proposed schedule at the end of this plan.
