NRC Acceptance Review of Byron/Braidwood Amendment to Remove Extraneous Detail Related to BEACON

Hi Brian,

By letter dated May 24, 2024 (Agencywide Documents Access and Management System (ADAMS) Accession No. ML24145A116), Constellation Energy Generation, LLC (Constellation) submitted a request for amendment for Byron and Braidwood Stations. Specifically, Constellation requested removal of extraneous detail related to the specific core monitoring system software (BEACON) and more closely align with the Standard Technical Specifications (STS), NUREG-1431 Revision 5. The purpose of this e-mail is to provide the results of the U.S.

Nuclear Regulatory Commission (NRC) staffs acceptance review of this request. The acceptance review was performed to determine if there is sufficient technical information in scope and depth to allow the NRC staff to complete its detailed technical review. The acceptance review is also intended to identify whether the application has any readily apparent information insufficiencies in its characterization of the regulatory requirements or the licensing basis of the plant.

The NRC staff has reviewed the request and concluded that it does provide technical information in sufficient detail to enable the NRC staff to complete its detailed technical review and make an independent assessment regarding the acceptability of the proposed alternative in terms of regulatory requirements and the protection of public health and safety and the environment. Given the lesser scope and depth of the acceptance review as compared to the detailed technical review, there may be instances in which issues that impact the NRC staffs ability to complete the detailed technical review are identified despite completion of an adequate acceptance review. If additional information is needed, you will be advised by separate correspondence.

Based on the information provided in your submittal, the NRC staff has estimated that this request will take approximately 160 hours0.00185 days <br />0.0444 hours <br />2.645503e-4 weeks <br />6.088e-5 months <br /> to complete. The NRC staff expects to complete this review by February 14, 2025. If there are emergent complexities or challenges in our review that would cause changes to the initial forecasted completion date or significant changes in the forecasted hours, the reasons for the changes, along with the new estimates, will be communicated during the routine interactions with the assigned project manager.

If you have any questions, please contact me at (301) 415-6606 or Joel.Wiebe@nrc.gov.
