UNITED STATES NUCLEAR REGULATORY COMMISSION WASHINGTON, D.C. 20555-0001 SAFETY EVALUATION BY THE OFFICE OF NUCLEAR REACTOR REGULATION RELATED TO AMENDMENT NO. 293 TO RENEWED FACILITY OPERATING LICENSE NO. NPF-9 AND AMENDMENT NO. 272 TO RENEWED FACILITY OPERATING LICENSE NO. NPF-17 DUKE ENERGY CAROLINAS, LLC MCGUIRE NUCLEAR STATION, UNITS 1 AND 2 DOCKET NOS. 50-369 AND 50-370

1.0 INTRODUCTION

By letter to the U.S. Nuclear Regulatory Commission (NRC, the Commission) dated May 5, 2016, as supplemented by letter dated June 16, 2016 (Agencywide Documents Access and Management System (ADAMS) Accession Nos. ML16134A068 and ML16180A179, respectively), Duke Energy Carolinas, LLC (Duke Energy) submitted an application seeking approval to change the Technical Specifications (TS) for McGuire Nuclear Station, Units 1 and 2 (MNS). The supplement dated June 16, 2016, provided additional information that clarified the application, did not expand the scope of the application as originally noticed, and did not change the staff's original proposed no significant hazards consideration determination as published in the Federal Register on July 5, 2016 (81 FR 43649).

The amendments would modify the MNS TS by removing footnote (c) from TS Table 3.3.2-1, "Engineered Safety Feature Actuation System Instrumentation," which is no longer applicable, and by removing an expired footnote from TS 3.8.1, "AC Sources - Operating."

By letter dated September 12, 2013 (ADAMS Accession No. ML13262A500), as supplemented by letters dated May 20 and July 22, 2014 (ADAMS Accession Nos. ML14161A231 and ML14205A440, respectively), Duke Energy submitted a license amendment request (LAR) related to MNS TS 3.3.2, which was needed for plant modifications to install new equipment in support of NRC Order EA-12-049, "Order Modifying Licenses with Regard to Requirements for Mitigation Strategies for Beyond-Design-Basis External Events" (ADAMS Accession No. ML12056A045). The NRC issued a license amendment on August 27, 2014 (ADAMS Enclosure 3

Accession No. ML14211A403) approving the changes requested in the LAR, which included modifying TS Table 3.3.2-1 by adding footnote (c). The final plant modifications in support of EA-12-049 were completed in the fall of 2015 (during the MNS Unit 2 refueling outage).

By letter dated June 7, 2007 (ADAMS Accession No. ML071590038), as supplemented by letter dated June 8, 2007 (ADAMS Accession No. ML071640098), Duke Energy submitted a one-time emergency LAR to add a footnote to TS 3.8.1. The LAR was need to support unanticipated repairs on the 1A Emergency Diesel Generator (EOG). The NRC issued a license amendment on June 8, 2007 (ADAMS Accession No. ML071570599) approving the changes. The 1A EOG repairs covered by the amendment have been completed, and the footnote expired on June 15, 2007, and is no longer applicable.

2.0 REGULATORY EVALUATION

In Title 10 of the Code of Federal Regulations (CFR) 50.36, the Commission established its regulatory requirements related to the content of TSs. Pursuant to 10 CFR 50.36, TS are required to include items in the following five specific categories related to station operation:

(1) safety limits, limiting safety system settings, and limiting control settings; (2) LCOs; (3) Surveillance Requirements (SRs); (4) design features; and (5) administrative controls.

3.0 TECHNICAL EVALUATION

The proposed changes to TS Table 3.3.2-1 and TS 3.8.1 are administrative, non-technical editorial changes only. The proposed change to TS Table 3.3.2-1 would remove a temporary footnote which was inserted as part of an NRG-approved license amendment to support the staggered implementation of plant modifications needed to comply with EA-12-049. The proposed change to TS 3.8.1 would delete a footnote, since expired, which allowed a one-time extension to the completion time for Required Action B.4 to support unanticipated 1A EOG repairs.

3.1 Licensee's Proposed Changes Duke Energy requests to delete footnote (c) from TS Table 3.3.2-1 related to FUNCTION 6.f. for Auxiliary Feedwater Pump Suction Transfer on Suction Pressure - Low. The footnote to be removed is the following:

(c) Prior to completion of the AC independent AFW pump suction transfer scheme modification on the respective Unit, the Allowable Value for this Function is ::::3 psig

(::::4 psig 2A MOP only) and the Nominal Trip Setpoint for this Function is 3.5 psig (4.5 psig 2A MOP only).

Duke Energy requests to delete a footnote in TS 3.8.1 related to the COMPLETION TIME of REQUIRED ACTION 8.4 for the 1A EOG. The footnote to be removed is the following:

  • For Unit 1 only, the Completion Time that the 1A EOG can be inoperable as specified by Required Action B.4 may be extended beyond the "72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> and 6 days from discovery of failure to meet the LCO" up to a total of 10 days as part of the 1A EOG Jacket/lntercooler Water Pump Motor repair. Upon completion of the repair and

restoration, this footnote is no longer applicable and will expire at 1741 hours0.0202 days <br />0.484 hours <br />0.00288 weeks <br />6.624505e-4 months <br /> on June 15, 2007.

3.2 NRC Staff Conclusion

The NRC staff finds that the proposed changes to TS Table 3.3.2-1 and TS 3.8.1 are administrative editorial changes which are non-technical in nature. The proposed change to TS Table 3.3.2-1 would remove a temporary footnote which was inserted as part of an NRC-approved license amendment to support the staggered implementation of plant modifications needed to comply with EA-12-049. The final plant modifications were completed during the fall 2015 MNS Unit 2 refueling outage. Therefore, the NRC staff concludes the removal of footnote (c) in TS Table 3.3.2-1 is acceptable.

The proposed change to TS 3.8.1 would delete a footnote which allowed a one-time extension to the completion time for Required Action 8.4 to support unanticipated 1A EOG repairs. The repairs covered by the footnote have been completed and the footnote is no longer applicable, as the footnote expired on June 15, 2007. Therefore, the NRC staff concludes the removal of the TS 3.8.1 footnote is acceptable.

The NRC staff concludes that with the deletion of the footnotes, McGuire Nuclear Station, Units 1 and 2, continue to meet the regulatory requirements of 10 CFR 50.36 and is, therefore, acceptable.

4.0 STATE CONSULTATION

In accordance with the Commission's regulations, the North Carolina State official was notified of the proposed issuance of the amendments on January 1, 2017. The State official had no comments.

5.0 ENVIRONMENTAL CONSIDERATION

The amendments change a requirement with respect to the installation or use of facility components located within the restricted area as defined in 10 CFR Part 20. The NRC staff has determined that the amendments involve no significant increase in the amounts and no significant change in the types of any effluents that may be released offsite and that there is no significant increase in individual or cumulative occupational radiation exposure. The Commission has previously issued a proposed finding that the amendments involve no significant hazards consideration, and there has been no public comment on this finding (July 5, 2016, 81 FR 43649). Accordingly, the amendments meet the eligibility criteria for categorical exclusion set forth in 10 CFR 51.22(c)(9). Pursuant to 10 CFR 51.22(b), no environmental impact statement or environmental assessment need be prepared in connection with the issuance of the amendments.

6.0 CONCLUSION

The Commission has concluded, based on the considerations discussed above, that: (1) there is reasonable assurance that the health and safety of the public will not be endangered by operation in the proposed manner, (2) there is reasonable assurance that such activities will be conducted in compliance with the Commission's regulations, and (3) the issuance of the amendments will not be inimical to the common defense and security or to the health and safety of the public.
