Acceptance Review - Hatch's 'Revise Technical Specifications to Adopt TSTF-591' LAR (L-2024-LLA-0122)

Good afternoon Adam, By letter dated September 11, 2024 (Agencywide Documents and A ccess Management System (ADAMS) Accession No. ML24255A891), Southern Nuclear Operating Company (SNC, the licensee) submitted a license amendment request (LAR)

Good afternoon Adam, By letter dated September 11, 2024 (Agencywide Documents and Access Management System (ADAMS) Accession No. ML24255A891), Southern Nuclear Operating Company (SNC, the licensee) submitted a license amendment request (LAR) for Edwin I. Hatch Nuclear Plant (Hatch), Units 1 and 2. The proposed LAR revises Hatch, Units 1 and 2, technical specifications (TS) to adopt TSTF-591, Revise Risk Informed Completion Time (RICT) Program. TSTF-591 revises TS Section 5.5 Program, Risk Informed Completion Time Program, to reference Regulatory Guide 1.200, Revision 3 (instead of Revision 2) and to make other changes. Also, a new report is added to TS Section 5.6, Reporting Requirements, to inform the U.S. Nuclear Regulatory Commission of newly developed methods used to calculate a RICT.

The purpose of this e-mail is to provide the results of the U.S. Nuclear Regulatory Commission (NRC) staffs acceptance review of this LAR. 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 Section 50.90 of Title 10 of the Code of Federal Regulations (10 CFR), an application for an amendment to a 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 LAR 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 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 licensing request will take approximately 75 hours8.680556e-4 days <br />0.0208 hours <br />1.240079e-4 weeks <br />2.85375e-5 months <br /> to complete. The NRC staff expects to complete this review on March 7, 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.

These estimates are based on the NRC staffs 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 NRC in advance or in parallel with industry program initiatives or pilot applications.

If you have any questions, please contact me.
