SAFETY EVALUATION BY THE OFFICE OF NUCLEAR REACTOR REGULATION RELATED TO AMENDMENT NO. 350 CONSTELLATION FITZPATRICK, LLC CONSTELLATION ENERGY GENERATION, LLC DOCKET NO. 50-333 JAMES A. FITZPATRICK NUCLEAR POWER PLANT TO RENEWED FACILITY OPERATING LICENSE NO. DPR-59

1.0 INTRODUCTION

By letter dated May 14, 2021 (Agencywide Documents Access and Management System (ADAMS) Accession No. ML21134A211), Exelon Generation Company, LLC submitted a request for changes to the James A. FitzPatrick Nuclear Power Plant Technical Specifications (TSs). On February 1, 2022 (ML22032A333), Exelon Generation Company, LLC was renamed Constellation Energy Generation, LLC (the licensee). The proposed changes would modify TS 3.3.1.1, RPS Instrumentation, by deleting Surveillance Requirements (SR) 3.3.1.1.5 and 3.3.1.1.6, which verify the overlap between the source range monitor (SRM) and the intermediate range monitor (IRM), and between the IRM and the average power range monitor (APRM).

The proposed changes are based on Technical Specifications Task Force (TSTF) traveler TSTF-264-A, Revision 0, 3.3.9 and 3.3.10 - Delete Flux Monitors Specific Overlap Requirement SRs, dated April 28, 1998 (ML040620165), as approved by letter dated July 26, 1999 (ML19067A141).

2.0 REGULATORY EVALUATION

The regulation at Title 10 of the Code of Federal Regulations (10 CFR) Part 50.36(c)(3) requires that TSs include items in the category of SRs, which are requirements relating to test, calibration, or inspection to assure that the necessary quality of systems and components is maintained, that facility operation will be within safety limits, and that the limiting conditions for operation (LCOs) will be met.

The NRC staffs guidance for the review of TSs is in chapter 16.0, Technical Specifications, of NUREG 0800, Revision 3, Standard Review Plan for the Review of Safety Analysis Reports for Nuclear Power Plants: LWR [Light Water Reactor] Edition (SRP), March 2010 (ML100351425).

As described therein, as part of the regulatory standardization effort, the NRC staff has prepared Standard Technical Specifications (STSs) for each of the LWR nuclear designs.

Accordingly, the NRC staffs review includes consideration of whether the proposed changes are consistent with NUREG-1433, Standard Technical Specifications, General Electric BWR/4 Plants, Volume 1, Specifications, and Volume 2, Bases, Revision 4.0, April 2012 (ML12104A192 and ML12104A193, respectively), as modified by NRC approved travelers.

3.0 TECHNICAL EVALUATION

3.1 Current FitzPatrick TS Requirements for Nuclear Instrumentation Neutron Flux Indication Overlap Verification TS 3.3.1.1, Reactor Protection System (RPS) Instrumentation, SRs 3.3.1.1.5 and 3.3.1.1.6, require verification of overlap for the SRM and IRM indications, and for the IRM and APRM indications, respectively. The Bases for these SRs explain what constitutes acceptable overlap in each case and state, in part, that:

Overlap between IRMs and APRMs exists when sufficient IRMs and APRMs concurrently have onscale readings such that the transition between MODE 1 and MODE 2 can be made without either APRM downscale rod block, or IRM upscale rod block. Overlap between the SRMs and IRMs similarly exists when, prior to withdrawing the SRMs from the fully inserted position, IRMs are above mid-scale on range 1 before SRMs have reached the upscale rod block.

The Frequency of SR 3.3.1.1.5 (IRM-SRM overlap verification) is, Prior to fully withdrawing SRMs. The surveillance column note in SR 3.3.1.1.6 (APRM-IRM overlap verification) states, Only required to be met during entry into MODE 2 from MODE 1. The Frequency of SR 3.3.1.1.6 is In accordance with the Surveillance Frequency Control Program.

SR 3.3.1.1.1 requires a CHANNEL CHECK of IRM and APRM channels in accordance with the surveillance frequency control program.

As specified in TS Table 3.3.1.1-1, in Mode 2, SR 3.3.1.1.5 applies to RPS Function 1.a, IRM Neutron Flux - High, and SR 3.3.1.1.6 applies to RPS Function 1.a, and Function 2.a, APRM Neutron Flux - High (Startup). In addition, SR 3.3.1.1.1 applies to both Function 1.a and Function 2.a.

3.2 Proposed FitzPatrick TS Requirements for Nuclear Instrumentation Neutron Flux Indication Overlap Verification The proposed change revises FitzPatrick TS 3.3.1.1, RPS Instrumentation, by deleting SR 3.3.1.1.5 and SR 3.3.1.1.6, which verify the SRM-IRM neutron flux indication overlap and the IRM-APRM neutron flux indication overlap, respectively. TS 3.3.1.1 retains the surveillance number designators but replaces the surveillance statement and any associated surveillance note with the phrase (Not used.) and leaves the frequency column blank in the SRs table rows for existing SR 3.3.1.1.5 and SR 3.3.1.1.6.

A CHANNEL CHECK is currently required for Functions 1.a and 2.a with a Frequency of In accordance with the Surveillance Frequency Control Program. FitzPatrick TS Section 1.1 defines a CHANNEL CHECK as follows (the same as the STS definition):

A CHANNEL CHECK shall be the qualitative assessment, by observation, of channel behavior during operation. This determination shall include, where possible, comparison of the channel indication and status to other indications or status derived from independent instrument channels measuring the same parameter.

As explained in TSTF-264-A, this definition of A CHANNEL CHECK in the STS may be interpreted as requiring SRM-IRM and IRM-APRM neutron flux indication overlap verification for the IRM-and APRM-associated RPS Functions that are required to be operable in Mode 2 (i.e., Functions 1.a and 2.a). Therefore, consistent with TSTF-264-A, the present indication overlap verifications may be considered redundant to the channel check SR.

The licensee stated that it will relocate the existing discussions of the SR 3.3.1.1.5 and SR 3.3.1.1.6 overlap verification requirements from the existing Bases to the Bases for SR 3.3.1.1.1. Specifically, the licensee plans to add the following paragraph to SR 3.3.1.1.1 Bases:

The agreement criteria includes an expectation of one decade of overlap when transitioning between neutron flux instrumentation. The overlap between SRMs and IRMs must be demonstrated prior to withdrawing SRMs from the fully inserted position since indication is being transitioned from the SRMs to the IRMs. This will ensure that reactor power will not be increased into a neutron flux region without adequate indication. The overlap between IRMs and APRMs is of concern when reducing power into the IRM range (entry into MODE 2 from MODE 1). On power increases, the system design will prevent further increases (by initiating a rod block) if adequate overlap is not maintained. Overlap between IRMs and APRMs exists when sufficient IRMs and APRMs concurrently have onscale readings such that the transition between MODE 1 and MODE 2 can be made without either APRM downscale rod block, or IRM upscale rod block. Overlap between SRMs and IRMs similarly exists when, prior to withdrawing the SRMs from the fully inserted position, IRMs are above mid-scale on range 1 before SRMs have reached the upscale rod block.

If overlap for a group of channels is not demonstrated (e.g., IRM/APRM overlap), the reason for the failure of the Surveillance should be determined and the appropriate channel(s) declared inoperable. Only those appropriate channels that are required in the current MODE or condition should be declared inoperable.

In adopting TSTF-264-A, the FitzPatrick TS 3.3.1.1 retains the surveillance number designators but replaces the surveillance statement and any associated surveillance note with the phrase (Not used.) and leaves the frequency column blank in the SRs table rows for existing SR 3.3.1.1.5 and SR 3.3.1.1.6. This is in lieu of removing these rows and renumbering the existing subsequent SRs, as done in the travelers markup of NUREG-1433, Revision 1. In addition, the references to these SRs in FitzPatrick TS Table 3.3.1.1-1 are removed.

References to SR 3.3.1.1.5 and SR 3.3.1.1.6 in the Bases for FitzPatrick TS 3.3.1.2, SRM Instrumentation, will be replaced by references to SR 3.3.1.1.1. No changes were needed to FitzPatrick TS 3.3.1.2 requirements on SRM channel operability, actions, or surveillances in Mode 2 with IRMs on Range 2 or below.

The licensee stated that it would maintain the existing neutron flux monitor channel indication overlap criteria by relocating the discussion of the criteria to the Bases for FitzPatrick TS SR 3.3.1.1.1 for RPS Functions 1.a and 2.a. The overlap check will be performed when SR 3.3.1.1.1 is performed for RPS Functions 1.a and 2.a. Although the TS Bases are a licensee-controlled document, changes to the TS Bases are controlled by the 10 CFR 50.59 process. The NRC staff finds that the licensee continues to uphold the previously approved definition of overlap and will maintain compliance with the requirement to verify SRM-IRM and IRM-APRM indication overlap at the necessary ranges of reactor power by performing the channel check specified for TS 3.3.1.1 Functions 1.a and 2.a at the Frequencies stated in the surveillance frequency control program.

The NRC staff has determined that the proposed changes are in accordance with NRC-approved TSTF-264, Revision 0, with no technical deviations, are consistent with STS Revision 4.0, and the overlap check will still be performed during surveillance testing.

Additionally, the NRC staff concludes that the requirements of 10 CFR 50.36(c)(3) continue to be met because the revised SR provides the appropriate surveillance to ensure the necessary quality of components is maintained and the LCO will be met. Based on the above, the NRC staff concludes the proposed changes to SR 3.3.1.1.5, SR 3.3.1.1.6, and Table 3.3.1.1 1 of FitzPatrick TS 3.3.1.1 to be acceptable.

4.0 STATE CONSULTATION

In accordance with the Commissions regulations, the New York State official was notified of the proposed issuance of the amendment on April 29, 2022. The State official had no comments.

5.0 ENVIRONMENTAL CONSIDERATION

The amendment changes a requirement with respect to installation or use of a facility component located within the restricted area as defined in 10 CFR Part 20 and changes surveillance requirements. The NRC staff has determined that the amendment involves 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 amendment involves no significant hazards consideration, and there has been no public comment on such finding (November 2, 2021; 86 FR 60484). Accordingly, the amendment meets 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 amendment.

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 amendment will not be inimical to the common defense and security or to the health and safety of the public.
