| | | On May 22, 2024, a closed meeting was held between the U.S. Nuclear Regulatory Commission (NRC), and representatives of Constellation Energy Generation, LLC (Constellation). The purpose of the meeting was for the NRC staff to discuss with Constellation a license amendment request for Limerick Generating Station, Units 1 and 2 (Limerick) dated September 26, 2022 (non-publicly available). The proposed amendment requests would change both the design and technical specifications to permit the use of a new single digital instrumentation and controls system to replace analog instrumentation of reactor protection system, analog nuclear steam supply shutoff system, emergency core cooling system, reactor core isolation cooling system, and end-of-cycle recirculation pump trip at Limerick. In addition, the proposed amendments would change the classification of the redundant reactivity control system from safety-related to non-safety-related, eliminate the automatic redundant reactivity control system feedwater runback function, eliminate the automatic isolation function for the turbine enclosure main steam line tunnel temperature high indication, eliminate several surveillance requirements, and allow the use of automated operator aids (or automated controls) from main control room. The meeting notice dated May 7, 2024, is available in Agencywide Documents Access and Management System at Accession No. ML24129A010. |

SUMMARY
OF MAY 22, 2024, CLOSED MEETING WITH CONSTELLATION ENERGY GENERATION, LLC, RELATED TO THE LICENSE AMENDMENT REQUEST TO SUPPORT REPLACEMENT OF EXISTING SAFETY-RELATED ANALOG CONTROL SYSTEMS WITH A SINGLE DIGITAL PLANT PROTECTION SYSTEM (EPID L-2022-LLA-0140)
On May 22, 2024, a closed meeting was held between the U.S. Nuclear Regulatory Commission (NRC), and representatives of Constellation Energy Generation, LLC (Constellation). The purpose of the meeting was for the NRC staff to discuss with Constellation a license amendment request for Limerick Generating Station, Units 1 and 2 (Limerick) dated September 26, 2022 (non-publicly available). The proposed amendment requests would change both the design and technical specifications to permit the use of a new single digital instrumentation and controls system to replace analog instrumentation of reactor protection system, analog nuclear steam supply shutoff system, emergency core cooling system, reactor core isolation cooling system, and end-of-cycle recirculation pump trip at Limerick. In addition, the proposed amendments would change the classification of the redundant reactivity control system from safety-related to non-safety-related, eliminate the automatic redundant reactivity control system feedwater runback function, eliminate the automatic isolation function for the turbine enclosure main steam line tunnel temperature high indication, eliminate several surveillance requirements, and allow the use of automated operator aids (or automated controls) from main control room. The meeting notice dated May 7, 2024, is available in Agencywide Documents Access and Management System at Accession No. ML24129A010.
The purpose of the meeting was to discuss the requests to withhold information provided in the license amendment request, as supplemented. Specifically, the NRC staff requested additional information on the affidavits submitted that requested to withhold the provided information. The licensee provided additional clarification to support the requests.
