SUPPLEMENTARY INFORMATION:

I. Background

    In accordance with section 51.118 of title 10 of the Code of 
Federal Regulations, ``Final environmental impact statement--notice of 
availability,'' the NRC is making available to the public NUREG-1437, 
Supplement 63 regarding the proposed renewal of the Constellation 
Energy Generation, LLC (CEG) Facility Operating License No. NPF-62 for 
an additional 20 years of operation for CPS. A notice of availability 
of the draft SEIS (NUREG-1437, Supplement 63, Draft Report for Comment) 
was published in the Federal Register on April 16, 2025 (90 FR 16011). 
The U.S. Environmental Protection Agency issued its notice of 
availability of the draft SEIS on April 18, 2025 (90 FR 16524). The 
public comment period on the draft SEIS ended on June 2, 2025, and the 
comments received on the draft SEIS are addressed in the final SEIS 
(NUREG-1437, Supplement 63, Final Report).

II. Discussion

    The draft SEIS (NUREG-1437, Supplement 63, Draft Report for 
Comment) was issued for public comment. The final SEIS (NUREG-1437, 
Supplement 63, Final Report) addresses the comments received on the 
draft SEIS. As discussed in Chapter 4 of the final SEIS, the NRC staff 
has determined that the adverse environmental impacts of license 
renewal for CPS (i.e., the continued operation of CPS for a period of 
20 years beyond the expiration date of the current operating license) 
are not so great that preserving the option of license renewal for 
energy-planning decision-makers would be unreasonable. This 
recommendation is based on: (1) information in the environmental 
report, as supplemented, and other documents submitted by CEG; (2) the 
NRC staff's consultation with Federal, State, Tribal, and local 
governmental agencies; (3) the NRC staff's independent environmental 
review; and (4) the NRC staff's consideration of public comments 
received during the scoping process and on the draft SEIS (NUREG-1437, 
Supplement 63, Draft Report for Comment).

    Dated: August 6, 2025.

    For the Nuclear Regulatory Commission.

Acting Deputy Director, Division of Rulemaking, Environmental, and 
Financial Support, Office of Nuclear Material Safety and Safeguards.
