SUBJECT:

NINE MILE POINT NUCLEAR STATION, UNIT 2 - PLAN FOR THE ONSITE AUDIT REGARDING IMPLEMENTATION OF MITIGATING STRATEGIES RELATED TO ORDER EA-12-049 (TAC NO. MF1130)

Dear Mr. Hanson On March 12, 2012, the U.S. Nuclear Regulatory Commission (NRC) issued Order EA-12-049, "Order Modifying Licenses with Regard to Requirements for Mitigation Strategies for Beyond Design-Basis External Events" and Order EA-12-051, "Order to Modify Licenses With Regard To Reliable Spent Fuel Pool Instrumentation, (Agencywide Documents Access and Management System (ADAMS) Accession Nos. ML12054A736 and ML12054A679, respectively). The orders require holders of operating reactor licenses and construction permits issued under Title 10 of the Code of Federal Regulations Part 50 to submit for review, Overall Integrated Plans (OIPs) including descriptions of how compliance with the requirements of Attachment 2 of each order will be achieved.

By letter dated February 28, 2013 (ADAMS Accession No. ML. 13066A171 ), Exelon Generation, LLC, previously as Constellation Energy Nuclear Group, LLC (Exelon, the licensee) submitted its OIP for Nine Mile Point Nuclear Station, Units 1 and 2 (NMP). in response to Order EA-12-049. By letter dated March 8, 2013 (ADAMS Accession No. ML13074A056), Exelon submitted a complete revision of the OIP for NMP. By letters dated August 27, 2013, February 27, 2014, August 26, 2014, February 19, 2015, and August 28. 2015 (ADAMS Accession Nos.

ML13254A278, ML14069A318, ML14241A380, ML15062A036, and ML15243A085, respectively), the licensee submitted its first five six-month updates to the OIP. By letter dated August 28, 2013 (ADAMS Accession No. ML13234A503), the NRC notified all licensees and construction permit holders that the staff is conducting audits of their responses to Order EA-12-049 in accordance with NRC Office of Nuclear Reactor Regulation (NRR) Instruction LIC-111, "Regulatory Audits" (ADAMS Accession No. ML082900195). This audit process led to the issuance of the NMP interim staff evaluation (ISE) and audjtreport (ADAMS Accession No. ML13225A584) and continues with in-office and onsite portion~ of this audit

B. Hanson By letter dated February 28, 2013 (ADAMS Accession No. ML13066A172), the licensee submitted its OIP for NMP in response to Order EA-12-051. By letter dated June 5, 2013 (ADAMS Accession No. ML13154A399), the NRC staff sent a request for additional information (RAI) to the licensee. By letters dated July 5, 2013, August 27, 2013, February 24, 2014, August 26, 2014, February 19, 2015, and August 28, 2015 (ADAMS Accession Nos.

ML13197A220, ML13254A279, ML14069A180, ML14241A016, ML15062A035, and ML15243A093, respectively), the licensee submitted its RAI responses and first five six-month updates to the OIP.

The NRC staff's review to date led to the issuance of the NMP ISE and RAI dated November 15, 2013 (ADAMS Accession No. ML13281A205). By letter dated March 26, 2014 (ADAMS Accession No. ML14083A620), the NRC notified all licensees and construction permit holders that the staff is conducting in-office and onsite audits of their responses to Order EA-12-051 in accordance with NRC NRR Office Instruction LIC-111, as discussed above.

The ongoing audit process, to include the in-office and onsite portions, allows the staff to assess whether it has enough information to make a safety evaluation of the Integrated Plans. The audit allows the staff to review open and confirmatory items from the mitigation strategies ISE, RAI responses from the spent fuel pool instrumentation ISE, the licensee's integrated plans, 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. The audit's onsite portion will occur prior to declarations of compliance for the first unit at each site.

This document outlines the on-site audit process that occurs after ISE issuance as licensees provide new or updated information via periodic updates, update audit information on e-portals, provide preliminary Overall Program Documents/Final Integrated Plans, and continue in-office audit communications with staff while proceeding towards compliance with the orders.

The staff conducted an onsite audit at NMP from November 3-7, 2014, in accordance with the audit plan dated October 8, 2014 (ADAMS Accession No. ML14274A288). Due to the different strategies and technologies between the units, the staff focused its review on Unit 1, since its compliance date is prior to Unit 2. By letter dated April 28, 2015 (ADAMS Accession No. ML15110A026), the staff issued an audit report for the November 3-7, 2014, onsite audit.

The staff plans to conduct an onsite audit of the Unit 2 strategies in accordance with the enclosed audit plan from November 16-20, 2015.

By letter dated March 26, 2014 (ADAMS Accession No. ML14083A620), the NRC notified all licensees and construction permit holders that the staff is conducting in-office and onsite audits of their responses to Order EA-12-051 in accordance with NRC NRR Office Instruction LIC-111, as discussed above.

Enclosure

The ongoing audit process, to include the in-office and onsite portions, allows the staff to assess whether it has enough information to make a safety evaluation of the Integrated Plans.

The audit allows the staff to review open and confirmatory items from the mitigation strategies ISE, RAI responses from the spent fuel pool instrumentation (SFPI) ISE, the licensee's integrated plans, 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. The audit's onsite portion will occur prior to declarations of compliance for the first unit at each site.

This document outlines the onsite audit process that occurs after ISE issuance as licensees provide new or updated information via periodic updates, update audit information on e-portals, provide preliminary Overall Program Documents (OPDs)/Final Integrated Plans (FIPs), and continue in-office audit communications with staff while proceeding towards compliance with the orders.

Following the licensee's declarations of order compliance, the NRC staff will evaluate the OIPs as supplemented, the resulting site-specific OPDs/FIPs, and, as appropriate, other licensee submittals based on the requirements in the orders. For Order EA-12-049, the staff will make a safety determination regarding order compliance using the Nuclear Energy Institute (NEI) guidance document NEI 12-06, "Diverse and Flexible Coping Strategies (FLEX) Implementation Guide" issued in August, 2012 (ADAMS Accession No. ML12242A378), as endorsed, by NRC interim staff guidance (ISG) JLD-ISG-2012-01 "Compliance with Order EA-12-049, 'Order Modifying Licenses with Regard to Requirements for Mitigation Strategies for Beyond-Design-Basis External Events"' (ADAMS Accession No. ML12229A174) as providing one acceptable means of meeting the order requirements. For Order EA-12-051, the staff will make a safety determination regarding order compliance using the NEI 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. ML12240A307),

as endorsed, with exceptions and clarifications, by NRC ISG JLD-ISG-2012-03 "Compliance with Order EA-12-051, 'Reliable Spent Fuel Pool Instrumentation'" (ADAMS Accession No. ML12221A339) as providing one acceptable means of meeting the order requirements. Should the licensee propose an alternative strategy or other method deviating from the guidance, additional staff review will be required to evaluate if the alternative strategy complies with the applicable order.

AUDIT SCOPE As discussed, onsite audits will be performed per NRR Office Instruction LIC-111, "Regulatory Audits," to support the development of safety evaluations. Site-specific OIPs and OPDs/FIPs rely on equipment and procedures that apply to all units at a site, therefore, audits will be planned to support the "first unit at each site." On-site audits for subsequent units at a site will be on an as-needed basis.

The purpose of the audits is to obtain and review information responsive to the NMP, Unit 2 OIP, as supplemented, open and confirmatory items from the mitigation strategies ISE, and to observe and gain a better understanding of the basis for the site's overall programs to ensure

the licensee is on the correct path for compliance with the Mitigation Strategies order. These may include, but are not limited to:

• Onsite review and discussion for the basis and approach for detailed analysis and calculations (Orders EA-12-049);

• Walk-throughs of strategies and laydown of equipment to assess feasibility, timing, and effectiveness of a given mitigating strategy or integration of several strategies (Order EA-12-049);

• Storage, protection, access, and deployment feasibility and practicality for onsite portable equipment (Order EA-12-049); and

• Evaluation of staging, access, and deployment of offsite resources to include equipment provided by the Strategic Alliance for FLEX Emergency Response (SAFER) from the National SAFER Response Centers (NSRCs) provided (Order EA-12-049).
