R.E. Ginna-Acceptance Review: Alternative for Examinations of Examination Category C-B Steam Generator Nozzle-to-Shell Welds and Nozzle Inside Radius Sections (EPID: L-2021-LLR-0074)
Date: Thursday, September 30, 2021 8:36:00 AM Attachments: image003.png
By letter dated September 1, 2021, (AgencywideDocuments Access and Management System(ADAMS) Accession No ML21244A328), Exelon Generation Company, LLC (Exelon, thelicensee) submitted a license amendment request (LAR) for the R.E.
Ginna Nuclear Power Plant (Ginna). The proposed alternative is to extend the frequency of steam generator nozzle-to-shell and nozzle inside radius sections volumetric and surface examinations for the remainder of the currently licensed operating periods.
The purpose of this letter is to provide the results of the NRC staff's acceptance review of this proposed alternative 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.
Consistent with 10 CFR 50.69, an amendment to the license (including the technical specifications) must fully describe the changes requested, and following, as far as applicable, the form prescribed for original applications. Section 50.34 of 10 CFR addresses the content of technical information required. This section stipulates that the submittal address the design and operating characteristics, unusual or novel design features, and principal safety considerations.
The NRC staff has reviewed your application 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 amendment 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 staff's 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 NRC staff's detailed technical review by separate correspondence.
Based on the information provided in your submittal, the NRC staff has estimated that this request will take approximately 175 hours0.00203 days <br />0.0486 hours <br />2.893519e-4 weeks <br />6.65875e-5 months <br /> to complete, excluding any contractor hours, if appropriate. The NRC staff expects to complete this review by September 30, 2022, 12 months from the date of this acceptance. 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, and the contractor resources will be communicated during the routine interactions with the assigned project manager.
These estimates are based on the NRC staff's initial review of the application and they could change, due to several factors including requests for additional information, unanticipated addition of scope to the review, and review by NRC advisory committees or hearing-related activities. Additional delay may occur if the submittal is provided to the NRG in advance or in parallel with industry program initiatives or pilot applications.
