CALVERT CLIFFS 1 AND 2 - ACCEPTANCE OF REQUESTED LICENSING ACTION RE AMENDMENT TO CHANGE SPENT FUEL POOL COOLING DESIGN BASIS (EPID L-2021-LLA-0112)

Date: Monday, July 19, 2021 3:19:00 PM Hello Frank, By letter dated June 14, 2021 (Agencywide Documents Access and Management System Accession No. ML21165A406), Exelon Generation Company, LLC submitted a license amendment request for Calvert Cliffs Nuclear Power Plant, Units 1 and 2. The purpose of this e-mail is to provide the results of the U.S. Nuclear Regulatory Commission (NRC) staffs acceptance review of this amendment 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 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.

Based on the information provided in your submittal, the NRC staff has estimated that the review of this amendment request will take approximately 600 hours0.00694 days <br />0.167 hours <br />9.920635e-4 weeks <br />2.283e-4 months <br /> to complete. The NRC staff expects to complete this review by January 14, 2022. 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.

Best Regards, Michael L. Marshall, Jr.
