Nuclear Regulatory Commission [Docket No. 50-285; NRC-2025-1831] AGENCY: Nuclear Regulatory Commission. ACTION: Notice; issuance. SUMMARY: The U.S. Nuclear Regulatory Commission (NRC) is issuing a finding of no significant impact (FONSI) and accompanying environmental assessment (EA) regarding the NRC's consideration of a license amendment request by Omaha Public Power District (OPPD) to approve the License Termination Plan (LTP), Revision 2 for the Fort Calhoun Station, Unit 1 (FCS), located in Washington County, Nebraska. If approved, the amendment would edit the dose calculations and final site survey (FSS) requirements for the Auxiliary Building basement and Containment Building for concrete structures deeper than 3 meters (m) (9.8 ( printed page 57789) feet [ft]). OPPD would use the LTP to meet the requirements for terminating the license and releasing the site for unrestricted use. Based on the EA, the NRC staff has concluded that there will be no significant impacts to environmental resources from the requested license amendment, and therefore, a FONSI is appropriate. DATES: The EA and FONSI referenced in this document is available on December 12, 2025.
