Abstract

This final supplement to the Generic Environmental Impact Statement for License Renewal of Nuclear Plants, Supplement 10, Second Renewal, Regarding Subsequent License Renewal for Peach Bottom Atomic Power Station Units 2 and 3 (Peach Bottom), Final Report (the 2020 FSEIS) incorporates new information that the U.S. Nuclear Regulatory Commission (NRC) staff has obtained since publication of the 2020 FSEIS in January 2020. This information includes the new and revised environmental issues and impact determinations contained in the NRC’s 2024 final rule revising its environmental protection regulation, Title 10 of the Code of Federal Regulations Part 51, "Environmental Protection Regulations for Domestic Licensing and Related Regulatory Functions," and Revision 2 of NUREG-1437, "Generic Environmental Impact Statement for License Renewal of Nuclear Plants." The NRC staff also considered any new and significant information with respect to generic (i.e., Category 1) environmental issues and determinations.

The NRC staff prepared these documents as part of its environmental review of the Exelon Generation Company, LLC (now Constellation Energy Generation, LLC) application to renew the operating licenses for Peach Bottom for an additional 20 years. Together, these documents complete the NRC staff’s evaluation of the environmental impacts of license renewal and alternatives to license renewal and support the staff's recommendation that the adverse environmental impacts of license renewal for Peach Bottom are not so great that preserving the option of license renewal for energy-planning decisionmakers would be unreasonable. Further, the NRC staff concludes that restoring the expiration dates for Peach Bottom’s subsequent renewed facility operating licenses for Units 2 and 3 to August 8, 2053, and to July 2, 2054, respectively, to authorize an additional 20 years of operation would not have impacts beyond those discussed in these documents and in Revision 2 of NUREG-1437.
