Subject:
Millstone Power Station, Unit 3-Acceptance of Requested Licensing Action Re Adoption of TSTF-601 Shield Building Completion Time After Refueling (EPID L-2025-LLA-0204)
Mr. Maynard, By \
letter dated December 18, 2025 (Agencywide Documents Access and Management System (ADAMS)
Accession No.ML25353A596), Dominion Energy Nuclear Connecticut, Inc. (the licensee) submitted a license amendment request (LAR) for Millstone Power Station, Unit No. 3. The proposed amendment would adopt Technical Specifications Task Force (TSTF)Traveler 601,"Extend Shield Building Completion Time After Refueling." The amendment would revise the technical specifications (TSs) in TS section 3.6.6.2, "Secondary Containment." The acceptance review was performed to determine whether the application contains sufficient technical information to allow the NRC staff to complete a detailed technical review. The acceptance review is also intended to identify any readily apparent deficiencies related to the characterization of the regulatory requirements or plant licensing basis.
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 application and concluded that it includes 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 more limited scope and depth of the acceptance review compared to the detailed technical review, issues that affect the NRC staffs ability to complete the technical review may still be identified despite the acceptance review being deemed adequate. If additional information is needed, you will be notified by separate correspondence.
Based on the information provided in your submittal, the NRC staff has determined that the amendment may be reviewed under the Consolidated Line-Item Improvement Process (CLIIP). The NRC staff has estimated that this licensing request will take approximately 60 hours6.944444e-4 days <br />0.0167 hours <br />9.920635e-5 weeks <br />2.283e-5 months <br /> to complete. The NRC staff expects to complete this review by June 19, 2026.
If emergent complexities or challenges arise during the NRC staffs review that affect the initial forecasted completion date or result in significant changes to the estimated review hours, the reasons for those changesalong with updated estimateswill be communicated during routine interactions with the assigned project manager. These estimates are based on the NRC staffs initial review of the application and may change due to several factors, including requests for additional information, unanticipated expansion of the review scope, hearing-related activities, or if the submittal is provided to the NRC in advance of or concurrently with industry program initiatives or pilot applications.
