Subject:
Brunswick Steam Electric Plant, Units 1 and 2 - Alternative Request for Reactor Pressure Vessel Nozzle-to-Vessel Weld and Inner Radii Examinations Date:
Wednesday, March 12, 2025 9:13:00 AM
Dear Ryan Treadway,
By application dated February25, 2025 (ML25057A278), Duke Energy Progress, LLC submitted a request in accordance with paragraph 50.55a(z)(1) of Title 10 of the Code of Federal Regulations (10 CFR) for a proposed alternative to certain requirements of 10CFR 50.55a, Codes and standards, at Brunswick Steam Electric Plant, Units 1 and 2.
Specifically, the application requests U.S. Nuclear Regulatory Commission (NRC) approval to reduce the population of reactor pressure vessel feedwater nozzle-to-vessel welds and inner blend radii examined during each inservice inspection interval.
The purpose of this email is to provide the results of the NRC staffs acceptance review of this proposed alternative.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 your application and concluded that it provides technical information in sufficient detail to enable the 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 staffs ability to complete the detailed technical review are identified despite completion of an adequate acceptance review.You will be advised of any further information needed to support the staffs detailed technical review by separate correspondence.
Based on the information provided in your submittal, the NRC staff estimates that review of 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 staff expects to complete its review by November14, 2025.These estimates are based on the staffs initial review of the application, and they could change due to several factors, including requests for additional information.If there are emergent complexities or challenges in our review that would cause changes to the initial forecasted completion date or significant changes to the forecasted hours, I will inform you of the reason for the change and provide the new estimates.
Sincerely,
Blake Purnell, Senior Project Manager Plant Licensing Branch II-2 Division of Operating Reactor Licensing Office of Nuclear Reactor Regulation
