SUPPLEMENTARY INFORMATION:

Notice is hereby given that the NRC has issued renewed facility operating license Nos. NPF-37 and NPF-66 to Exelon Generation Company, LLC, the operator of Byron. Renewed facility operating license Nos. NPF-37 and NPF-66 authorize operation of Byron Units 1 and 2 by the licensee at reactor core power levels not in excess of 3645 megawatts thermal each, in accordance with the provisions of the Byron, Units 1 and 2 renewed licenses and technical specifications. The NRC's ROD that supports the NRC's decision to renew facility operating license Nos. NPF-37 and NPF-66 is available in ADAMS under Accession No. ML15187A304. As discussed in the ROD and the final supplemental environmental impact statement (FSEIS) for Byron Station, Supplement 54 to NUREG-1437, “Generic Environmental Impact Statement for License Renewal of Nuclear Plants Regarding Byron Station, Units 1 and 2,” dated July 2015 (ADAMS Accession No. ML15196A263), the NRC has considered a range of reasonable alternatives that included new nuclear generation, coal-integrated gasification combined cycle, natural gas combined-cycle (NGCC), combination (NGCC, wind, and solar generation), replacement power, and the no-action alternative. The ROD and FSEIS document the NRC determination that the adverse environmental impacts of license renewal for Byron are not so great that preserving the option of license renewal for energy planning decision makers would be unreasonable.

Byron Station, Units 1 and 2 has two pressurized water reactors and is located in Ogle County, Illinois. The application for the renewed licenses, “License Renewal Application, Byron and Braidwood Stations, Units 1 and 2,” dated May 29, 2013 (ADAMS Accession Nos. ML13155A420 and ML13155A421, respectively), as supplemented by letters dated through April 13, 2015, with respect to Byron Station, complied 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 the NRC's regulations in Chapter I of title 10 of the Code of Federal Regulations, the NRC has made appropriate findings, which are set forth in each of the licenses. A public notice of the proposed issuance of the renewed licenses and an opportunity for a hearing was published in the Federal Register on July 24, 2013 (78 FR 44603).
