Dear Benjamin Pearson:
By letter dated June 18, 2024 (Agencywide Documents Access and Management System (ADAMS) Accession No. ML24177A132), Omaha Public Power District (OPPD) requested the U.S. Nuclear Regulatory Commission (NRC) to approve a request to amend the license for Fort Calhoun Station, Unit No. 1 (FCS).

Enclosure RSI-01 RESRAD files and calculations spreadsheet Comment: The RESRAD input and output files and the spreadsheet of equations and calculations (Reference [13] Omaha Public Power District, "Excel Spreadsheet Calculations in Support of FCS LTP Chapter 6, Revision 0") used to determine the revised derived concentration guideline level (DCGL) values were not provided with the license amendment request (LAR). This information is needed to ensure that the assumptions and values identified in the LAR were included in the RESRAD and spreadsheet calculations that demonstrate that the proposed DCGLs will result in meeting the dose criteria for unrestricted use in 10 CFR 20.1402.
Basis: The LAR proposes changes to the DCGLs associated with the revised remediation strategy for the Auxiliary Building basement. These updated, site-specific DCGLs were calculated using a combination of RESRAD-ONSITE, Version 7.2, and spreadsheet calculations. Although listed in the LAR, neither the RESRAD-ONSITE files nor the spreadsheet documenting the calculations were provided with the LAR. This information is needed to confirm that the assumptions and specific parameter values used in the revised calculations were considered and that the resulting values match the values provided in the LAR.
Request: Provide the updated RESRAD-ONSITE input and output files and summary reports as well as Reference [13] Omaha Public Power District, "Excel Spreadsheet Calculations in Support of FCS LTP Chapter 6, Revision 0," with the updated calculations used in the LAR.
