UNITED STATES NUCLEAR REGULATORY COMMISSION WASHINGTON, D.C. 20555-0001 SAFETY EVALUATION BY THE OFFICE OF NUCLEAR REACTOR REGULATION RELATED TO AMENDMENT NO. 301 TO RENEWED FACILITY OPERATING LICENSE NO. NPF-9 AND AMENDMENT NO. 280 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 or Commission) 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 specifications (TSs) for McGuire Nuclear Station, Units 1 and 2 (McGuire).
The amendments modify TS 3.1.8, "PHYSICS TESTS Exceptions," to allow the numbers of channels required to be operable by the limiting condition of operation (LCO) section of TS 3.3.1, "Reactor Trip System (RTS) Instrumentation, to be reduced from "4" to "3" to allow one nuclear instrumentation channel to be used as an input to the reactivity computer for physics testing without placing the nuclear instrumentation channel in a tripped condition.
The changes are consistent with Technical Specifications Task Force (TSTF) Traveler TSTF-315-A, Revision 0, "Reduce plant trips due to spurious signals to the NIS [Nuclear Instrumentation System] during physics testing, (ADAMS Accession No. ML040620172).
The NRC approved TSTF-315-A, Revision 0, in a letter dated June 29, 1999 (ADAMS Legacy Accession No. 9907060395).
2.0 REGULATORY EVALUATION
2.1 RTS Instrumentation Description McGuire's Updated Final Safety Analysis Report, Section 7 .2.1.1.2, "Reactor Trips", states, in part:
Enclosure 3
The various reactor trip circuits automatically open the reactor trip breakers whenever a condition monitored by the Reactor Protection System reaches a preset or calculated level. ...
TS 3.3.1, Table 3.3.1-1 lists the RTS Instrumentation functions.
The RTS functions related to the subject license amendment request are the following:
Function 2 - Power Range Neutron Flux (Low and High)
The Power Range Neutron Flux - High trip function ensures protection against a positive reactivity excursion leading to departure from nucleate boiling during power operation. The Power Range Neutron Flux - Low trip function ensures protection against a positive reactivity excursion from low power or subcritical conditions.
Function 3 - Power Range Neutron Flux Rate (High Positive Rate)
The Power Range Neutron Flux - High Positive Rate trip function ensures that protection is provided against rapid increases in neutron flux.
Function 6 - Overtemperature LiT The Overtemperature LiT trip function is provided to ensure that the design departure from nucleate boiling rate is met.
Function 16.d - RTS Interlocks (Power Range Neutron Flux, P-10)
RTS interlocks ensure reactor trips are in the correct configuration for the given plant status.
Power Range Neutron Flux, P-10 RTS interlock is actuated at approximately 10% power.
2.1 Licensee's Proposed Changes Current TS LCO 3. 1. 8, states:
During the performance of PHYSICS TESTS, the requirements of LCO 3.1.3, "Moderator Temperature Coefficient (MTC)";
LCO 3.1.4, "Rod Group Alignment Limits";
LCO 3.1.5, "Shutdown Bank Insertion Limits";
LCO 3.1.6, "Control Bank Insertion Limits"; and LCO 3.4.2, "RCS [Reactor Coolant System] Minimum Temperature for Criticality" may be suspended, provided:
- a. RCS lowest loop average temperature is ;;:: 541°F [degrees Fahrenheit]; and
- b. SOM [Shutdown Margin] is within the limits provided in the COLR [Core Operating Limits Report].
Revised TS LCO 3.1.8, would state:
During the performance of PHYSICS TESTS, the requirements of LCO 3.1.3, "Moderator Temperature Coefficient (MTC)";
LCO 3.1.4, "Rod Group Alignment Limits";
LCO 3.1.5, "Shutdown Bank Insertion Limits";
LCO 3.1.6, "Control Bank Insertion Limits"; and LCO 3.4.2, "RCS Minimum Temperature for Criticality" may be suspended, and the number of required channels for LCO 3.3.1, RTS [Reactor Trip System] Instrumentation," Functions 2, 3, 6, and 16.d, may be reduced to "3" required channels, provided:
- a. RCS lowest loop average temperature is ~ 541°F; and
- b. SOM is within the limits provided in the COLR.
2.3 Applicable Regulations and Guidance As described in Title 10 of the Code of Federal Regulations (10 CFR) Section 50.36(c)(2)(i),
"Limiting conditions for operation are the lowest functional capability or performance levels of equipment required for safe operation of the facility."
The amendments adopt previously NRG-approved TSTF-315-A, Revision 0 to bring McGuire's TSs into alignment with NUREG-1431, Revision 4, "Standard Technical Specifications -
Westinghouse Plants: Specifications" (Volume 1), which contains the improved Standard Technical Specifications (STS) for Westinghouse plants.
3.0 TECHNICAL EVALUATION
3.1 NRC Staff's Technical Evaluation of Licensee's Proposed Changes The NRC staff compared the licensee's proposed changes against NRG-approved TSTF-315-A, Revision 0, and NUREG-1431, Revision 4, "Standard Technical Specifications - Westinghouse Plants: Specifications" (Volume 1).
TSTF-315-A, Revision 0, revised STS 3.1.10, "PHYSICS TESTS Exceptions - MODE 2," to allow the number of channels to be operable of Functions 2, 3, 6, and 18.e required by LCO 3.3.1, "Reactor Trip System (RTS) Instrumentation," to be reduced from "4" to "3" to allow one nuclear instrumentation channel to be used as an input to the reactivity computer for physics testing without placing the affected nuclear instrumentation channel in a tripped condition.
The following provides a description for the associated functions:
STS LCO 3.3.1 RTS Equivalent McGuire STS RTS Function Title Function No. LCO 3.3.1 RTS Function No.
2 2 Power Range Neutron Flux
- HiQh, and - Low 3 3 Power Range Neutron Flux Rate High Positive Rate 6 6 Overtemperature /':.. T 18.e 16.d RTS Interlocks Power Range Neutron Flux, P-10 McGuire TS 3.1.8, "PHYSICS TESTS Exceptions," is equivalent to TS 3.1.10 from the STS markup included in TSTF-315-A, Revision 0. TSTF-315-A, Revision 0, which is based on NUREG-1431 Revision 1, identifies that a physics test exception is applicable to LCO 3.3.1 Functions 2, 3, 6, and 18.e. In NUREG-1431, Function 18.e of TS 3.3.1Table3.3.1-1, "Reactor Trip System Instrumentation," pertains to "Power Range Neutron Flux, P-1 O." Function 16.d is the corresponding function in TS Table 3.3.1-1 of the McGuire TSs. Therefore, the McGuire TSs are modified to apply to LCO 3.3.1 Functions 2, 3, 6, and 16.d.
Reducing the required number of the operable channels from "4" channels to "3" channels creates a two-out-of-three logic (from an one-out-of-three) for trip Functions 2, 3, 6, and 16.d.
The change in TS LCO 3.1.8 does not change the TS LCO 3.3.1 requirement for "4" operable channels for Functions 2, 3, 6, and 16.d in MODE 2 when not conducting physics tests.
The NRC staff has reviewed the licensee's proposed changes to TS 3.1.8 and concludes that reducing the number of required channels to be operable for LCO 3.3.1 Functions 2, 3, 6, and 16.d from "4" to "3" is adequate because the "3" required channels of Functions 2, 3, 6, and 16.d will continue to provide adequate reactor protection should anticipated operational occurrences occur.
The NRC staff concludes that the requirements of 10 CFR 50.36(c)(2) continue to be met because the minimum performance level of equipment needed for safe operation of the facility is contained in the LCO.
Based on the above, the NRC staff concludes that this change, consistent with guidance in TSTF-315-A, Revision 0 and NUREG-1431, Revision 4, is acceptable.
4.0 STATE CONSULTATION
In accordance with the Commission's regulations, the NRC staff notified the North Carolina State official of the proposed issuance of the amendments on September 18, 2017. The State official confirmed on September 22, 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 23621: May 23, 2017). 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.
