UNITED STATES NUCLEAR REGULATORY COMMISSION WASHINGTON, D.C. 20555-0001 SAFETY EVALUATION BY THE OFFICE OF NUCLEAR REACTOR REGULATION RELATED TO AMENDMENT NO. 298 TO RENEWED FACILITY OPERATING LICENSE NO. NPF-9 AND AMENDMENT NO. 277 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 United States Nuclear Regulatory Commision (NRC) dated January 11, 2017 (Agencywide Documents Access and Management System (ADAMS) Accession No. ML17025A069), Duke Energy Carolinas, LLC (Duke Energy) submitted an application to seek approval to change the Technical Specification (TSs) for McGuire Nuclear Station, Units 1 and 2 (McGuire).
This license amendment request (LAR) modifies TS 3.6.3, "Containment Isolation Valves," to add a Note to Required Actions A.2, C.2, and E.2 to allow isolation devices that are locked, sealed, or otherwise secured to be verified by use of administrative means. The licensee stated that this change is consistent with Technical Specifications Task Force (TSTF) Traveler TSTF-269-A, Revision 2, "Allow administrative means of position verification for locked or sealed valves" (ADAMS Accession No. ML040620100). The NRC approved TSTF-269, Revision 2 in a letter dated July 26, 1999 (ADAMS Legacy Accession No. 9907300113).
2.0 REGULATORY EVALUATION
In Title 10 of the Code of Federal Regulations (10 CFR) Section 50.36, the Commission established its regulatory requirements related to the content of TSs. Pursuant to 10 CFR 50.36, TSs are required to include items in the following categories related to station operation: (1) safety limits, limiting safety system settings, and limiting control settings; (2) limiting conditions for operation (LCOs); (3) surveillance requirements (SRs); (4) design features; and (5) administrative controls. The regulation does not specify the particular requirements to be included in a plant's TSs.
The NRC staff used Revision 3 of the WOG STS (ADAMS Accession No. ML041830612) in its review of the TS changes proposed for McGuire.
Enclosure 3
2.1 Licensee's Proposed Changes Current TS LCO 3.6.3, Condition A states, "One or more penetration flow paths with one containment isolation valve inoperable except for purge valve or reactor building bypass leakage not within limit." Required Action A.2 states, Verify the affected penetration flow path is isolated.
With a Completion Time of:
Once per 31 days for isolation devices outside containment AND Prior to entering MODE 4 from MODE 5 if not performed within the previous 92 days for isolation devices inside containment.
Current TS LCO 3.6.3, Condition C states, "One or more penetration flow paths with one containment isolation valve inoperable." Required Action C.2 states, Verify the affected penetration flow path is isolated.
With a Completion Time of:
Once per 31 days.
Current TS LCO 3.6.3, Condition E states, "One or more penetration flow paths with one or more containment purge valves not within purge valve leakage limits." Required Action E.2
- states, Verify the affected penetration flow path is isolated.
With a Completion Time of:
Once per 31 days for isolation devices outside containment AND Prior to entering MODE 4 from MODE 5 if not performed within the previous 92 days for isolation devices inside containment.
Revised TS LCO 3.6.3 would add the following NOTE (as NOTE 2) under Required Actions A.2, C.2, and E.2.
Isolation devices that are locked, sealed, or otherwise secured may be verified by use of administrative means.
The current NOTE for TS LCO 3.6.3 Required Actions A.2, C.2, and E.2 would be renumbered to be NOTE 1.
3.0 TECHNICAL EVALUATION
TSTF-269-A, Revision 2, revised WOG STS 3.6.3, "Containment Isolation Valves (Atmospheric, Subatmospheric, Ice Condenser, and Dual)," by adding a note under Required Actions A.2, C.2, and E.2 that isolation devices that are locked, sealed, or otherwise secured may be verified by use of administrative means.
Periodic verification is required for a penetration with an inoperable isolation valve in order to detect and correct inadvertent repositioning of the isolation device. Because the purpose of locking, sealing or securing components is to prevent inadvertent repositioning, the licensee proposed that periodic re-verification should be a verification of the administrative controls that ensure that the component remains in the required state. TS LCO 3.6.3 states, "Each containment isolation valve shall be OPERABLE." The OPERABILITY requirements for isolation valves ensure that components are capable of performing their safety functions within the time limits assumed in the safety analyses. Updated Final Safety Analysis Report Section 6.2.1.6.2 states that during plant operation certain tests and inspections are conducted to ensure the functional capability of containment and associated structures, systems, and components (including the containment isolation valves). It is reasonable to assume that the initial establishment of component status (i.e., closing of an isolation valve) was performed sufficiently, and subsequent, periodic re-verification of the administrative control is thus sufficient to demonstrate continued isolation. Additionally, it is undesirable to remove the lock, seal, or other means of securing the component solely to perform an active verification of the components required state, as it would increase the possibility of mis-positioning the component due to frequent manipulations.
The NRC staff has reviewed the proposed changes to TS LCO 3.6.3 and has determined that the licensee's proposed use of administrative controls provides adequate assurance that the valves are maintained in the positions required by the plant safety analyses when primary and secondary containment are required to be operable.
3.1 NRC Staff's Conclusion Based on the above, the NRC staff concludes that the proposed TS changes, consistent with TSTF-269-A, Revision 2, would continue to meet the requirements of 10 CFR 50.36(c)(2)(i) and is, therefore, acceptable, since the proposed administrative controls provide reasonable assurance of plant safety.
4.0 STATE CONSULTATION
In accordance with the Commission's regulations, the NRC staff notified the South Carolina State official of the proposed issuance of the amendments on August 16, 2017. The State official confirmed on September 6, 2017, that the State of North Carolina had no comments.
5.0 PUBLIC COMMENTS On May 23, 2017, the NRC staff published a "Notice of Consideration of Issuance of Amendments to Facility Operating Licenses, Proposed No Significant Hazards Consideration Determination, and Opportunity for a Hearing," in the Federal Register associated with the proposed amendment request (82 FR 23619). In accordance with the requirements in 10 CFR 50.91, the notice provided a 30-day period for public comment on the proposed no significant hazards consideration determination. One comment from a member of the public was received, however it was not related to the no significant hazards consideration
determination nor the LAR. The comment can be found at www.regulations.gov, reference NRC-2017-0120-0002.
6.0 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 (82 FR 23619). 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.
7.0 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.
