<HD SOURCE="HD1">I. Discussion</HD>
Notice is hereby given that the NRC has issued Renewed Facility Operating License No. NPF-62 to Constellation for Clinton. Constellation is the operator of the facility. Renewed Facility Operating License No. NPF-62 authorizes Constellation to operate Clinton at reactor core power levels not in excess of 3,473 megawatts thermal, in accordance with the provisions of the Clinton renewed facility operating license and the technical specifications. Notice is also given that the ROD that supports the NRC's decision to issue Renewed Facility Operating License No. NPF-62 is available, and its location is listed in the “Availability of Documents” section of this document.
As discussed in the ROD and the final supplemental environmental impact statement (SEIS), published as NUREG-1437, Supplement 63, “Generic Environmental Impact Statement for License Renewal of Nuclear Plants Regarding License Renewal for Clinton Power Station, Unit 1, Final Report,” dated August 2025, the final SEIS documents the NRC staff's environmental review, including the recommendation that the adverse environmental impacts of license renewal (LR) for Clinton are not so great that preserving the option of LR for energy-planning decisionmakers would be unreasonable. This recommendation is based on (1) the analysis and findings in the NRC's Generic Environmental Impact Statement for License Renewal of Nuclear Plants, (2) information provided in the environmental report submitted by Constellation, as supplemented, (3) the NRC staff's consultation with Federal, State, Tribal, and local agencies, (4) the NRC staff's independent environmental review, and (5) the NRC staff's consideration of public comments received during the scoping process and on the draft SEIS.
Clinton is a boiling water reactor located on Clinton Lake in DeWitt County, approximately 6 miles east of the city of Clinton in east-central Illinois. Constellation submitted its application for the renewed license, “Clinton Power Station, Unit 1 Application for Renewed Operating License,” on February 14, 2024, as supplemented by letters through April 10, 2025 (see “Availability of Documents” section of this document). The NRC staff has detemined that Constellation's application complies with the standards and requirements of the Atomic Energy Act of 1954, as amended (the Act), and the NRC's regulations. As required by the Act and NRC regulations in title 10 of the
<E T="03">Code of Federal Regulations</E>
(10 CFR), the NRC has made appropriate findings, which are set forth in the renewed license.
A public notice of the NRC's acceptance for docketing of the LR application and an opportunity to request a hearing was published in the
<E T="04">Federal Register</E>
on April 18, 2024 (89 FR 27805).
For further details with respect to this action, see: (1) Constellation's LR application for Clinton, dated February 14, 2024, as supplemented by letters through April 10, 2025; (2) the NRC's safety evaluation, dated August 2025; (3) the NRC's final SEIS, dated August 2025; and (4) the NRC's ROD, dated December 16, 2025.
