1. Summary Description Pursuant to Section 50.90 of Title 10 of the Code of Federal Regulations (1 O CFR), Duke Energy Carolinas (DEC) herein proposes to correct an editorial error contained in Technical Specification (TS) 3.0, SURVEILLANCE REQUIREMENT (SR) APPLICABILITY, SR 3.0.5 and proposes removal of expired Technical Specification (TS) footnotes from the MNS Unit 1 and Unit 2 TSs.
2. Detailed Description The proposed changes to Renewed Facility Operating License (FOL) NPF-9 and to Renewed FOL NPF-17 for the MNS Units 1 and 2, respectively, described below are administrative non-technical changes only.

Proposed correction to FOL NPF-9 and NPF-17 TS 3.0, SR APPLICABILITY, SR 3.0.5 2.1. By letter dated April 11, 2006, (Adams Accession Number ML061080409), DEC submitted a license amendment application for Technical Specification Change to Add/Revise LCO 3.0.8 on the lnoperability of Snubbers Using the Consolidated Line Item Improvement Process (CLIIP). By letter dated March 29, 2007, (Adams Accession Number ML063100490), the U.S. Nuclear Regulatory Commission issued Amendment No. 238 to FOL NPF-9 and Amendment No. 220 to FOL NPF-17. In the amendment application DEC proposed to renumber existing TS 3.0.8 to TS 3.0.9. DEC failed to provide the marked-up copy of page 3.0-6 showing the following change as being required.

SR 3.0.5 Surveillance Requirements shall apply to each unit individually unless otherwise indicated as stated in LCO 3.0.i 9 for individual Specifications or whenever certain portions of a Specification contain surveillance parameters different for each unit, which will be identified in parentheses or footnotes.

DEC proposes to correct this editorial error as shown in Attachment 1.

Proposed changes to FOL NPF-9 and NPF-17 TS Footnotes.

2.2. By letter dated September 14, 2017, (Adams Accession Number ML17262A090), as supplemented by letter dated December 12, 2017, (Adams Accession Number ML17349A157), DEC proposed a LAR for the TSs for the MNS, Units 1 and 2, to allow temporary changes to TS 3.5.2, Emergency Core Cooling System (ECCS) - Operating; TS 3.6.6, Containment Spray System (CSS); TS 3.7.5, Auxiliary Feedwater System;

ENCLOSURE RA-18-0232 Page 3 of 7 (AFW) TS 3.7.6, Component Cooling Water Jew) System; TS 3.7.7, Nuclear Service Water System (NSWS); TS 3.7.9, Control Room Area Ventilation System (CRAVS); TS 3.7.11, Auxiliary Building Filtered Ventilation Exhaust System (ABFVES), and TS 3.8.1, .

AC Sources- Operating. The proposed amendment permitted the 'A' Train NSWS to be inoperable for a total of 14 days to address a non-conforming condition on the 'A' Train supply piping from the Standby Nuclear Service Water Pond (SNSWP). By letter dated February 15, 2018, (Adams Accession Number ML18030A682), the U.S. Nuclear Regulatory Commission issued Amendment No. 308 to FOL NPF-9 and Amendment No.

287 to FOL NPF-17 allowing the 'A' Train NSWS to be inoperable for a total of 14 days to address a non-conforming condition on the 'A' Train supply piping from the SNSWP.

The 'A' Train NSWS non-conforming condition associated with the 'A' Train supply piping from the SNSWP was resolved on May 3, 2018, therefore the associated TS footnotes are considered expired. DEC proposes to remove the expired footnotes from the above-mentioned TSs.

2.3. By letter dated October 28, 2013, (Adams Accession Number ML133048445), as supplemented by letter dated June 3, 2014, (Adams Accession Number ML14164A028),

DEC, submitted a license amendment request to modify TS 3.8.4, "DC Sources-Operating." Specifically, the change provided a one-time extension to the completion time for Required Action A.2.2 to support replacement of the existing shared 125 VDC Vital Batteries. By letter dated September 10, 2014, (Adams Accession Number ML14231A634), the U.S. Nuclear Regulatory Commission issued Amendment No. 274 to FOL NPF-9 and Amendment No. 254 to FOL NPF-17.

MNS completed replacement of the Vital Batteries in May 2016. The TS 3.8.4 footnote associated with Amendments 27 4 and 254 expired on December 31, 2016. DEC proposes to remove the expired footnote from TS 3.8.4.

2.4. By letter dated August 28, 2015, (Adams Accession Number ML152448179), as suppleniented by letter dated November 13, 2015, (Adams Accession Number ML15331A039), DEC, submitted a license amendment request to modify TS Completion Time for TS 3.5.2, "ECCS [Emergency Core Cooling System] - Operating," Condition A.

Specifically, the amendment would allow a one-time extension of the Completion Time to support maintenance on residual heat removal air handler unit 1A. By letter dated February 3, 2016, (Adams Accession Number ML16004A352), the U.S. Nuclear Regulatory Commission issued Amendment No. 281 to FOL NPF-9.

The TS 3.5.2 footnote associated with Amendment 281 expired on March 31, 2016. DEC proposes to remove the expired footnote from TS 3.5.2.

ENCLOSURE RA-18-0232 Page 4 of 7

3. T~chnical Evaluation The proposed change to SR 3.0.5 to correct the editorial error is an administrative non-technical change.

The proposed changes to TS 3.5.2, 3.6.6, 3.7.5, 3.7.6, 3.7.7, 3.7.9, 3.7.11 and 3.8.4 to remove the expired footnotes identified by a single asterisk, proposed change to TS 3.8.1 to remove the expired footnote identified by a double asterisk and the proposed change to TS 3.5.2 to remove the expired footnote identified by a single dagger are administrative non-technical changes.

Given the above, additional Technical Evaluation of the administrative non-technical changes proposed in this LAR is not necessary.

4. Regulatory Evaluation 4.1 Applicable Regulatory Requirements/Criteria The proposed changes in this LAR are administrative and non-technical in nature.

Upon approval and implementation of the proposed changes, MNS Units 1 and 2 will continue to comply with the applicable regulatory requirements and criteria discussed in the following Regulatory Evaluation:

as supplemented by letter dated December 12, 2017, (Adams Accession Number ML17349A157), which was approved by the NRC as .part of their February 15, 2018, SER, (Adams Accession Number ML18030A682).

  • . DEC's October 28, 2013, LAR, (Adams AGcession Number ML133048445), as supplemented by letter dated June 3, 2014, (Adams Accession Number ML14164A028), which was approved by the NRC as part of their September 10, 2014, SER, (Adams Accession Number ML14231A634).
  • DEC's August 28, 2015, LAR, (Adams Accession Number ML152448179), as supplemented by letter dated November 13, 2015, (Adams Accession Number ML15331A039), which was approved by the NRC as part of their February 3, 2016, SER, (Adams Accession Number ML16004A352).

ENCLOSURE RA-18-0232 Page 5 of 7

which was approved by the NRC as part of their March 29, 2007, SER, (Adams Accession Number ML063100490)

Therefore, additional discussion of the applicable regulatory requirements and criteria is not necessary.

4.2 No Significant Hazards Consideration Determination Analysis Pursuant to Section 50.90 of Title 1O of the Code of Federal Regulations (10 CFR), DEC herein submits a license amendment request (LAR) for McGuire Nuclear Station (MNS) Unit 1 and 2. This request for amendment proposes to correct an editorial error contained in Technical Specification (TS) 3.0, SURVEILLANCE REQUIREMENT (SR) APPLICABILITY, SR 3.0.5 and proposes removal of expired Technical Specification (TS) footnotes from the MNS Unit 1 and Unit 2 TSs.

DEC has evaluated whether a significant hazards consideration is involved with the proposed amendment by analyzing the three standards set forth in 10 CFR 50.92(c) as discussed below:

1) Does the proposed amendment involve a significant increase in the probability or consequences of an accident previously evaluated?

Response: No.

This LAR proposes administrative non-technical changes only. These proposed changes do not adversely affect accident initiators or precursors nor alter the design assumptions, conditions, or configurations of the facility. The proposed changes do not alter or prevent the ability of structures, systems and components (SSCs) to perform their* intended function to mitigate the consequences of an initiating event within the assumed acceptance limits.

Given the above discussion, it is concluded the proposed amendment does not significantly increase the probability or consequences of an accident previously evaluated.

2) Does the proposed amendment create the possibility of a new or different kind of accident from any accident previously evaluated?

Response: No.

ENCLOSURE RA-18-0232 Page 6 of 7 T~is LAR proposes administrative non-technical changes! only. The proposed changes will not alter the design requirements of any Structure, System or Component (SSC) or its function during accident conditions. No new or different accidents result from the proposed changes. The changes do not involve a physical alteration of the plant or any changes in methods governing normal plant operation. The changes do not alter

  • assumptions made in the safety analysis.

Given the above discussion, it is concluded the proposed amendment does not create the possibility of a new or different kind of accident from any accident previously evaluated.

3) Does the proposed amendment involve a significant reduction in a margin of safety?

Response: No.

This LAR proposes administrative non-technicc;il changes only. The proposed changes do not alter the manner in which safety limits, limiting safety system settings or limiting conditions for operation are determined. The safety analysis acceptance criteria are not affected by these changes. The proposed changes will not result in plant operation in a configuration outside the design basis. The prop9sed changes do not adversely affect systems that respond to safely shutdown the plant and to maintain the plant in a safe shutdown condition.

  • Given the above discussion, it is concluded the proposed amendment does not involve a significant reduction in the margin of safety.

4.3 Conclusion Based on the above, DEC concludes that the proposed amendment does not involve a significant hazards consideration under the standards set forth in 10 CFR 50.92(c), and accordingly, a finding of no significant hazards consideration is justified.

5. Environmental bonsiderations This LAR proposes administrative non-technical changes only; DEC has determined that the propo$ed amendment does not change requirements with respect to the installation or use of a facility component located within the restricted area, as defined by 10 CFR 20. DEC has evaluated the proposed changes and has determined that they do not involve: (1) a significant .hazards consideration, (2) a significant change in the types or a significant increase in the amounts of any effluents that may be released offsite, or (3) a significant increase in individual or cumulative occupational radiation exposures. Accordingly, the proposed amendment meets the eligibility criterion for categorical exclusion set forth in 10 CFR 51.22(c)(9). Therefore, pursuant to 10 CFR 51.22(b), no environmental impact statement or environmental assessment needs to be prepared in connection with the proposed amendment.

ECCS-Operating B 3.5.2 BASES ACTIONS (continued)

An event accompanied by a loss of offsite power and the failure of an EOG can disable one EQCS train until power is restored. A reliability analysis (Ref. 6) has shown that the impact of having one full ECCS train inoperable is sufficiently small to justify continued operation for 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br />.

Reference 7 describes situations in which one component, such as an RHR crossover valve, can disable both ECCS trains. With one or more component(s) inoperable such that 100% of the flow equivalent to a single OPERABLE ECCS train is not available, the facility is in a condition outside the accident analysis. Therefore, LCO 3.0.3 must be immediately entered.

As part of the 1A RHR AHU repair evolution, the Completion Time that one train of EGGS can be inoperable as specified by Required Action A.1 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 />" for up to 10 days (on Unit 1 only). This allowance may be used one time for the 1A RHR AHU repair.

Upon completion of the repair and restoration, the Completion Time footnote is no longer applicable and \Viii expire on March 31, 2016. The commitments from the LAR submittal are as follows:

8.1 and 8.2 If the inoperable trains cannot be returned to OPERABLE status within the associated Completion Time, the plant must be brought to a MODE in which the LCO does not apply. To achieve this status, the plant must be brought to MODE 3 within 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br /> -and MODE 4 within 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br />. The allowed Completion Times are reasonable, based on operating experience, to reach the required plant conditions from full power conditions in an orderly manner and without challenging plant systems.

SURVEILLANCE SR 3.5.2.1 REQUIREMENTS Verification of proper valve position ensures that the flow path from the ECCS pumps to the RCS is maintained. Misalignment of these valves could render both ECCS trains inoperable. Securing these valves using the power disconnect switches in the correct position ensures that they cannot change position as a result of an active failure or be inadvertently misaligned. These valves are of the type, described in Reference 7, that can disable the function of both ECCS trains and invalidate the accident analyses. The Surveillance Frequency is based on operating experience, equipment reliability, and plant risk and is controlled under the Surveillance Frequency Control Program.

SR 3.5.2.2 Verifying the correct alignment for manual, power operated, and automatic valves in the ECCS flow paths provides assurance that the proper flow paths will exist for ECCS operation. This SR does not apply McGuire Units 1 and 2 B 3.5.2-8 Revision No. 49

DC Sources-Operating B 3.8.4 BASES ACTIONS (continued)

If one of the required channels of DC is inoderable (e.g., inoperable battery, inoperable battery charger(s), or inoperable battery charger and associated inoperable battery), the remaining DC channels have the capacity to support a safe shutdown and to mitigate an accident condition. If the channel of DC cannot be restored to OPERABLE status, Action A.2 must be entered and the DC channel must be energized from an OPERABLE channel; from the same train, within 2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br />. The capacity of the redundant channel is sufficient to supply its normally supplied channel and cross tied channel for the required time, in case of a OBA event. The inoperable channel of DC must be returned to OPERABLE status within 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> and the cross ties to the other channel open. The 72 hour8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> Completion Time reflects a reasonable time to assess unit status as a function of the inoperable channel of DC and, if the DC channel is not restored to OPERABLE status, to prepare to effect an orderly and safe unit shutdown.

As part of the battery replacement project, the Completion Time that one channel of DC source can be inoperable as specified by Required Action A2.2 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 />" for up to 14 days. This allowance may be used one time for each of the four DC channels. Upon completion of the battery replacement project, the Completion Time footnote is no longer applicable and will expire on December 31, 2016.

B.1 and B.2 If the inoperable chann_el of DC cannot be restored to OPERABLE status within the required Completion Time, the unit must be brought to a MODE in which the LCO does not apply. To achieve this status, the unit must be brought to at least MODE 3 within 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br /> and to MODE 5 within 36 hours4.166667e-4 days <br />0.01 hours <br />5.952381e-5 weeks <br />1.3698e-5 months <br />.
