Subject:

Millstone Power Station, Unit Nos. 2 and 3 - Acceptance Review Determination for Proposed LAR for TS Change Applicable to TSTF-359, "Increase Flexibility in Mode Restraints" (EPID L-2022-LLA-0052)

Shayan, By letter dated April 6, 2022 (Agencywide Documents Access and Management System (ADAMS) Accession No. ML22096A221), Dominion Energy Nuclear Connecticut, Inc. (the licensee) submitted a license amendment request (LAR) to revise the Technical Specifications (TSs) for Millstone Power Station, Unit No. 2 and Unit No. 3. Specifically, the proposed amendment would modify TS requirements for mode change limitations in limiting condition for operation (LCO) 3.0.4 and surveillance requirement (SR) 4.0.4 applicable to the adoption of Technical Specifications Task Force (TSTF) Traveler 359, "Increase Flexibility in Mode Restraints," Revision 9 (ADAMS Accession No. ML031190607). The availability of TSTF-359 for adoption by licensees was announced in the Federal Register on April 4, 2003 (68 FR 16579) as part of the consolidated line item improvement process (CLIIP).

The purpose of this e-mail is to provide the results of the U.S. Nuclear Regulatory Commission (NRC) staffs acceptance review of this proposed licensing action. 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),

whenever a holder of an operating license under this part desires to amend the license, application for an amendment must be filed with the Commission fully describing 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 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 140 hours0.00162 days <br />0.0389 hours <br />2.314815e-4 weeks <br />5.327e-5 months <br /> to complete. The NRC staff expects to complete this review by May 3, 2023. If there are emergent complexities or challenges in our review that would cause changes to the initial forecasted completion date (greater than

a month) or significant changes in the forecasted hours (greater than 25%), 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.

If you have any questions, please contact me.
