SUBJECT:
WESTINGHOUSE 10CFR70.72 FACILITY CHANGE REPORT FOR 2025 Westinghouse Electric Company LLC (Westinghouse) hereby submits the report of Columbia Fuel Fabrication Facility (CFFF) changes that did not require prior U.S. Nuclear Regulatory Commission (NRC) approval in accordance with 10CFR70.72. This report addresses those changes completed within calendar year 2025. Westinghouse did not complete any facility changes that required prior NRC approval during the above time period.
Westinghouse uses an integrated safety review approach for all modifications of, or additions to, existing structures, systems and components at the CFFF. This process is described in and conducted in accordance with the requirements of CFFF Regulatory Procedure RA-104, "Regulatory Review of Configuration Change Authorization." This integrated review is conducted by the various regulatory disciplines, including Nuclear Criticality Safety, Radiation Safety, Environmental Protection, Safeguards, Fire Safety, Chemical/Industrial Safety and other applicable Health and Safety experts when necessary. A key aspect of this review is a determination that the change is not prohibited by 10CFR70, a SNM-1107 license condition, or a governing order. The reviewers also determine whether NRC pre-approval and SNM-1107 license amendment changes are required prior to implementation.
Specific guidance is provided to ensure that prior NRC approval is obtained for changes that:
Create new types of accident sequences that, unless mitigated or prevented, would exceed the performance requirements of 10CFR70.61 and that have not previously been described in the Integrated Safety Analysis (ISA) Summary; Use new processes, technologies or control systems for which the licensee has no prior experience; Remove, without at least an equivalent replacement of the safety function, an Items Relied On For Safety (IROFS) that is listed in the ISA Summary and is necessary for compliance with the performance requirements of 10CFR70.61; or Alter any IROFS listed in the ISA Summary, that is the sole item preventing or mitigating an accident sequence that exceeds the performance requirements of 10CFR70.6l.
Each of the Configuration Control Forms (CCF) identified in the enclosure to this correspondence were evaluated in accordance with the RA-104 procedure, and a determination was made that prior NRC approval of the respective change was not required. This determination was documented on each change authorization form by the appropriate regulatory engineering review functions. For all of these changes,
WESTINGHOUSE NON-PROPRIETARY CLASS 3 LTR-RAC-26-08 Page 2 of 2
© 2026 Westinghouse Electric Company LLC All Rights Reserved the regulatory engineering review function checked the "No" box on the form for "Does the proposed change require NRC approval?"
If you have any questions regarding this information, please contact me at (803) 647-3193.
