Ms. Croft:

By application dated June 13, 2023 (ADAMS Accession No. ML23164A170), Constellation Energy Generation, LLC (CEG) (the licensee) submitted a license amendment request in accordance with 10 CFR 50.90, Application for amendment of license, construction permit, or early site permit to the Technical Specifications (TS) for Calvert Cliffs Nuclear Power Plant Units 1 and 2.

Specifically, the proposed amendment adopts the NRC-approved Technical Specification [TS]

Task Force (TSTF) Improved Standard Technical Specifications Change Traveler TSTF-59-A, Incorporate [Combustion Engineering] NPSD-994 Recommendations into the [Safety Injection Tank] Specification, Revision 1.

The proposed amendment modifies TS 3.5.1 Condition A to add the condition where one safety injection tank is inoperable due to the inability to verify level or pressure. The changes also extend the Condition B allowed outage time from 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br /> to 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> when one safety injection tank is inoperable for reasons other than Condition A.

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 100 hours0.00116 days <br />0.0278 hours <br />1.653439e-4 weeks <br />3.805e-5 months <br /> to complete. The staff expects to complete its review by June 29, 2024. 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, Sujata Goetz Project Manager, Calvert Cliffs Nuclear Regulatory Commission
