SUBJECT:

CLINTON POWER STATION, UNIT 1, LICENSE RENEWAL APPLICATION -

PUBLIC MEETING

SUMMARY

OF PRE-SUBMITTAL MEETING

Dear Christopher Wilson:

By letter dated July 29, 2019 (Agencywide Documents Access and Management System (ADAMS) Accession No. ML19210C877), Constellation Energy Generation, LLC, (CEG or the applicant), submitted a letter of intent to submit a license renewal application (LRA) for Clinton Power Station (Clinton), Unit 1.

On June 28, 2023, an Observation Meeting was held between the U.S. Nuclear Regulatory Commission (NRC or the staff) and representatives of CEG. The purpose of the meeting was to discuss the expected content for the safety review of the upcoming submittal of the LRA for Clinton. The meeting notice and agenda dated June 28, 2023, are available at ML23179A020.

The staff presentation is available at ML23172A209, and the applicants presentation is available at ML23172A210. A list of participants is provided as Enclosure 1. The NRC staff also held a public meeting with CEG to discuss the environmental review on June 27, 2023. A summary of that meeting is available at ML23200A259.

The NRC staff began with a brief overview of the license renewal (LR) process. The process consists of two tracks: the environmental review and the safety review. During the meeting, the staff shared a tentative schedule for the safety review of the application. The application submission date is expected to be February 2024, however, the final licensing decision is to be determined pending the completion of the environmental review. For the Clinton LRA, the NRC staff intends to incorporate process improvements and lessons learned from previous LRA reviews.

CEG began its presentation with general plant information of Clinton Unit 1. Clintons current license was issued on April 17, 1987, and it is set to expire April 17, 2027. Clinton was granted an exemption which allows CEG to submit a license renewal application for Clinton at least three years prior to the expiration of its existing license and, if the application is sufficient, to still receive timely renewal protection.

CEG also discussed its approach for developing the Clinton LRA. The applicant indicated that it intends to leverage the format and content contained in NUREG-1800, Revision 2, Standard Review Plan for Review of License Renewal Applications for Nuclear Power Plants (SPR-LR)

(ML103490036), NUREG-1801, Revision 2, Generic Aging Lessons Learned (GALL-LR)

Report (ML103490041), Regulatory Guide 1.188, Revision 2, Standard Format and Content for Applications to Renew Nuclear Power Plant Operating Licenses (ML20017A265) and LR Interim Staff Guidance in the development of its application. CEG stated that regulatory guidance provided by NUREG-2191, Revision 0, Generic Aging Lessons Learned for Subsequent License Renewal (GALL-SLR) Report, Volumes 1 and 2 (ML17187A031 and ML17187A204, respectively) and subsequent license renewal interim staff guidance (SLR-ISGs) are being considered from the perspective of operating experience.

CEG presented its scoping and screening approach, highlights of its aging management review (AMR) process, and its aging management programs (AMPs) that are applicable to Clinton. For the AMRs, the applicant stated that Clinton AMR line items will be compared with the GALL-LR Report, and that the AMR results will be conducted using a methodology that is consistent with current standards and Nuclear Energy Institute (NEI) 95-10, Revision 6, Industry Guideline for Implementing the Requirements of 10 CFR Part 54 - The License Renewal Rule. The application for Clinton is expected to have a total of 44 AMPs, all of which were developed to maximize consistency with the GALL-LR Report. Of the 44 AMPs, 36 are existing programs, while eight are new programs. A total of 10 AMPs is expected to be consistent with the GALL-LR Report; 20 AMPs are expected to be consistent with enhancements; three AMPs are expected to be consistent with exceptions; and three AMPs are expected to be consistent with exceptions and enhancements. Clinton does not plan to have any plant-specific AMPS.

To support its LRA, CEG stated that it is utilizing lessons learned from previous CEG and industry license renewal projects. This includes its extensive aging management experience and participation in NEI and Electric Power Research Institute initiatives related to license renewal and long-term operations. CEG noted that it reviews breakout questions, requests for additional information, requests for confirmation of information, and supplements associated with recent license renewal applications to ensure consistency with current NRC expectations and SRP-LR guidance. CEG also stated that an industry peer review of the LRA will be performed. CEG will also utilize the Scientech eDocs portal to support the NRC review. The applicant concluded the meeting by stating that the Clinton LRA is on track to be submitted on February 14, 2024.

During the NRC/CEG question and answer (Q&A) portion of the meeting, the NRC staff provided a few questions and comments. The NRC staff asked whether there will be any enhancements from using the GALL-SLR Report. CEG reiterated that the GALL-SLR Report and SLR-ISGs are being considered from the perspective of operating experience. The NRC staff also advised caution on the use of the term active assembly in their application and to determine if traveling screens are within scope of license renewal at Clinton. CEG appreciated the comments and would take them back for consideration.

There were no questions from members of the public during the public Q&A portion of the meeting.

If you have any questions, please feel free to contact me by email at Christopher.Tyree@nrc.gov.

Sincerely,

/RA/
