Dear Mr. Rhoades:

The U.S. Nuclear Regulatory Commission (the Commission) has issued the enclosed Amendment No. 296 to Renewed Facility Oper ating License No. DPR-29 and Amendment No. 292 to Renewed Facility Operating License No. DPR-30 for the Quad Cities Nuclear Power Station, Units 1 and 2, respectively. The amendments consist of changes to the technical specifications (TSs) in response to your application dated February 3, 2023.

The amendments adopt Technical Specifications Task Force (TSTF) Traveler 416 (TSTF-416),

Revision 0, Low Pressure Coolant Injection (LPCI) Valve Alignment Verification Note Location.

The adoption of TSTF-416 revises TS 3.5.1, ECCS [Emergency Core Cooling Systems]-

Operating, by moving the LPCI valve alignment note from Surveillance Requirement 3.5.1.2 to Limiting Condition for Operation 3.5.1.

1.0 INTRODUCTION

By letter to the U.S. Nuclear Regulatory Commission (NRC, the Commission) dated February 3, 2023 (Agencywide Documents A ccess and Management System Accession No. ML23034A219), Constellation Energy Generation, LLC (the licensee) submitted a license amendment request (LAR) to change the technical specifications (TSs) for the Quad Cities Nuclear Power Station, Units 1 and 2 (Quad Cities).

The proposed change would revise the emergency core cooling systems (ECCS) TSs based upon NRC-approved Technical Specifications Task Force (TSTF) Traveler TSTF-416, Revision 0, Low Pressure Coolant Injection (LPCI) Valve Alignment Verification Note Location (ML012390252), and the associated NRC staff safety evaluation (SE) (ML022240526).

2.0 REGULATORY EVALUATION

2.1 Description of Proposed Change

The LAR proposed to revise Quad Cities TS 3.5.1, ECCS-Operating, by moving the LPCI valve alignment note located in Surveillance Requir ement (SR) 3.5.1.2 to Limiting Condition for Operation (LCO) 3.5.1. The LPCI valve alignment note states:

Low pressure coolant injection (LPCI) subsystems may be considered OPERABLE during alignment and operation for decay heat removal with reactor steam dome pressure less than the Residual Heat Removal (RHR) cut in permissive pressure in MODE 3, if capable of being manually realigned and not otherwise inoperable.

Enclosure 3

2.2 Variations

The LAR identified one variation from TSTF-416. Section 3.0 of this SE provides a description of the variation and the NRC staffs evaluation.

2.3 Applicable Regulatory Requirements

Title 10 of the Code of Federal Regulations (10 CFR) section 50.36, Technical specifications, paragraph (c)(2), Limiting conditions for operati on, requires that TSs include LCOs. According to 10 CFR 50.36(c)(2)(i), LCOs are the lowest functional capability or performance levels of equipment required for safe operation of the facility. This regulation also requires that when an LCO of a nuclear reactor is not met, the licensee shall shut down the reactor or follow any remedial action permitted by the TSs until the LCO can be met.

The regulation at 10 CFR 50.36(c)(3), Surveillance requirements, requires that TSs include SRs and states that SRs 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 [LCOs] will be met.

2.4 Applicable Regulatory Guidance

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), dated 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 the applicable STSs, NUREG-1433, 1 as modified by NRC-approved travelers.

3.0 TECHNICAL EVALUATION

Traveler TSTF-416 revised STS 3.5.1, ECCS - Operating, by moving the LPCI valve alignment note for SR 3.5.1.2 to LCO 3.5.1.

The NRC staff compared the proposed TS change described in section 2.1 of this SE against the change in NRC-approved TSTF-416. In accordance with SRP chapter 16.0, the NRC staff determined that the change in NRC-approved TSTF-416 is applicable to the Quad Cities TSs because the Quad Cities units are boiling-water reactors (BWRs) and the NRC approved the TSTF-416 change for BWR designs. The NRC staff also determined that the proposed change to the Quad Cities TSs described in section 2.1 of this SE conforms to the change made to the STSs by NRC-approved TSTF-416.

In its SE for TSTF-416, the NRC staff concluded that the TSTF-416 change to STS 3.5.1 is acceptable because the SR 3.5.1.2 LPCI valve alignment note applies to all LPCI/RHR subsystem shared components; however, the note is located in the SRs that only address valve operability. The NRC staffs SE also stated that the preferred location for this note is in the LCO

1 U.S. Nuclear Regulatory Commission, Standard Technical Specifications, General Electric BWR/4 Plants, NUREG-1433, Volume 1, Specifications, and Volume 2, Bases, Revision 5.0, dated September 2021 (ML21272A357 and ML21272A358, respectively).

because the LCO applies to the components of the shared portions of the LPCI/RHR subsystem. TSTF-416 did not change the design or function of any safety-or nonsafety-related systems or components previously reviewed by the NRC staff and found acceptable. The NRC staffs SE for TSTF-416 concluded that moving the note is an administrative change.

Based on the above discussion, the NRC staff concludes that the proposed change to Quad Cities TS 3.5.1 to move the LPCI valve alignment note from the SR to the LCO is consistent with NRC-approved TSTF-416 and conforms to the applicable STS. The NRC staff also concludes that the proposed change clarifies the lowest functional capability or performance levels of equipment required for safe operation of the facility and continues to assure that the necessary quality of systems and components is maintained, that facility operation will be within safety limits, and that the LCO will be met. Therefore, the NRC staff finds that the proposed change continues to meet the requirements of 10 CFR 50.36(c)(2) and 10 CFR 50.36(c)(3).

The LAR identified one variation from the NRC-approved TSTF-416. Specifically, TSTF-416 includes moving LPCI valve alignment notes located in SRs 3.5.1.2 and 3.5.2.4 to LCOs 3.5.1 and 3.5.2, respectively. However, the licensee has already incorporated the relocation of the SR 3.5.2.4 LPCI valve alignment note into TS 3.5.2 as part of Amendment Nos. 273 and 268 for Quad Cities, Units 1 and 2, respectively, related to the adoption of TSTF-542, Reactor Pressure Vessel Water Inventory Control (ML18353A229). As a result, the LAR only requested relocation of the LPCI valve alignment note from SR 3.5.1.2 to LCO 3.5.1. Based on the above discussion, the NRC staff concludes that this variation is acceptable because the TSTF-416 proposed changes to SR 3.5.2.4 and LCO 3.5.2 have already been incorporated.

4.0 STATE CONSULTATION

In accordance with the Commissions regulations, the Illinois State official was notified of the proposed issuance of the amendments on June 27, 2023. The State official had no comments.

5.0 ENVIRONMENTAL CONSIDERATION

The amendments change requirements with respect to the installation or use of facility components located within the restricted area as defined in 10 CFR part 20 and change surveillance requirements. 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 such finding (88 FR 31282; dated May 16, 2023). 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 Commissions 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.
