Supplement to License Amendment Request to Revise Technical Specifications and Exemption Request from Requirements of 10CFR50.62 ATWS Rule to Support the Digital Modernization Project Installation - Revise Unit 1 Technical Specifications
References:
- 1. Constellation Energy Generation, LLC (CEG) letter to the U.S. Nuclear Regulatory Commission (NRC), "License Amendment Request to Revise the Licensing and Design Basis to Incorporate the Replacement of Existing Safety-Related Analog Control Systems with a Single Digital Plant Protection System (PPS)," dated September 26, 2022 (NRC Agencywide Documents Access and Management System (ADAMS) Accession No. ML22269A5690).

Constellation Energy Generation, LLC letter to U.S. Nuclear Regulatory Commission, Supplement to License Amendment Request to Revise the Licensing and Design Basis to Incorporate the Replacement of Existing Safety-Related Analog Control Systems with a Single Digital Plant Protection System (PPS)-Pivot to Unit 2 First Installation, dated May 23, 2023 (ADAMS Accession No. ML23143A342).
Per Reference 1, and in accordance with 10 CFR 50.90, Constellation Energy Generation, LLC (CEG) requested amendments to Renewed Facility Operating License Nos. NPF-39 and NPF-85 for Limerick Generating Station (LGS), Units 1 and 2, respectively. The proposed changes would revise the LGS licensing and design basis to incorporate a planned digital modification at LGS (i.e., the LGS Digital Modernization Project).
Supplement to Installation Support LAR for DMP Docket Nos. 50-352 and 50-353 July 31, 2023 Page 2 Per Reference 2, and in accordance with 10 CFR 50.90, Constellation Energy Generation, LLC (CEG) requested an amendment to Appendix A, "Technical Specifications" (TS) of Renewed Facility Operating License Nos. NPF-39 and NPF-85 for Limerick Generating Station (LGS), Units 1 and 2, respectively. Reference 2 also contained an Exemption Request from requirements of 10CFR50.62 ATWS Rule. The proposed changes will revise the LGS Technical Specifications (TS) to adopt features from NUREG-1433, Revision 5, "Standard Technical Specifications for General Electric BWR/4 Plants." The proposed changes will support the installation of the new Plant Protection System (PPS) described in Reference 1.
Per Reference 3, CEG notified NRC that the final design activities for the PPS have been delayed due to additional design refinement iterations with the system Original Equipment Manufacturer. CEG had concluded that it was no longer possible to have the design completed and equipment ready in time to support the Unit 1 installation during the April 2024 Refueling Outage. CEG had decided to pivot final design and project activities to support the first installation of the PPS on Unit 2 during its planned April 2025 Refueling Outage.
Accordingly, the Unit 1 marked-up Technical Specifications (TSs) in Reference 3 that contain references to the 2024 Refueling Outage need to be revised to reflect the Unit 1 installation occurring during its Spring 2026 Refueling Outage. CEG considers this a minor administrative change and the reason for the changes are necessary to align with the current project installation schedule for Unit 1. Therefore, an evaluation of the proposed TS changes is not warranted. Unit 2 TS markups, as proposed in Reference 2, are unaffected.
Unit 1 TS page 3/4 1-20 is being revised to reflect that, in SR 4.1.5.b.4 Note ***, refueling outage is changing from 2024 to 2026 as follows:
For a period of 30 days preceding exit of OPERATIONAL CONDITION 1 at the start of the 2026 refueling outage, no pumps are required to start automatically.
Unit 1 TS page 3/4 3-17 is being revised to reflect that, in Table 3.3.2-1 Reactor Water Cleanup System Isolation Trip Function 3.d on SLCS Initiation Note (h), refueling outage is changing from 2024 to 2026 as follows:
For a period of 30 days preceding exit of OPERATIONAL CONDITION 1 at the start of the 2026 refueling outage, the Reactor Water Cleanup System Isolation on SLCS Initiation Trip Function is not required to be OPERABLE.
Unit 1 TS page 3/4 3-31 is being revised to reflect that, in Table 4.3.2.1-1 Reactor Water Cleanup System Isolation Trip Function 3.d on SLCS Initiation Note (b), refueling outage is changing from 2024 to 2026 as follows:
For a period of 30 days preceding exit of OPERATIONAL CONDITION 1 at the start of the 2026 refueling outage, the Reactor Water Cleanup System Isolation on SLCS Initiation Trip Function is not required to be OPERABLE.
Supplement to Installation Support LAR for DMP Docket Nos. 50-352 and 50-353 July 31, 2023 Page 3 Unit 1 TS page 3/4 3-42 is being revised to reflect that, in LCO 3.3.4.1 for ATWS Recirculation Pump Trip System Instrumentation Applicability Note (Insert 1), the refueling outage is changing from 2024 to 2026 as follows:
For a period of 30 days preceding exit of OPERATIONAL CONDITION 1 at the start of the 2026 refueling outage, the LCO is not applicable when the following conditions are met:
The Attachment to this letter contains only the revised markups of the affected TS pages provided in Reference 2.
CEG has reviewed the information supporting a finding of no significant hazards consideration, and the environmental consideration, which was previously provided to the NRC in the Reference 2 letter. CEG has concluded that the information provided in this supplemental letter does not affect the bases for concluding that the proposed license amendments do not involve a significant hazards consideration under the standards set forth in 10 CFR 50.92. In addition, CEG has concluded that the information in this supplemental letter does not affect the bases for concluding that neither an environmental impact statement nor an environmental assessment needs to be prepared in connection with the proposed amendments.
This supplemental letter contains no regulatory commitments.
In accordance with 10 CFR 50.91, "Notice for public comment; State consultation,"
paragraph (b), CEG is notifying the Commonwealth of Pennsylvania of this license amendment request supplement by transmitting a copy of this letter to the designated State Official.
If you have any questions regarding this submittal, then please contact Frank Mascitelli at Francis.Mascitelli@constellation.com.
I declare under penalty of perjury that the foregoing is true and correct. Executed on this 31st day of July 2023.
