Correction to Previous Submittal of 10 Code of Federal Regulations 70.59 Effluent Reporting

Dear John Lubinski and Laura Dudes:

The purpose of this letter is to submit corrected pages for American Centrifuge Operating, LLC ' s (ACO) 10 Code of Federal Regulations 70.59 effluent report previously submitted on August 29,

2024 (Reference 1). Specificall y, two conservative errors were identified during further internal reviews of the sampling data relating to the total estimated exposure. Enclosure 1 contains corrected pages 1 and 2 for Enclosure 1 of ACO 24-0069 and are shown with a revision bar in the right-hand margin.

If you have any questions regarding this matter, please coritact Stephen Howie, Radiation Protection Manager at (740) 897-2347.

Sincerely,

~fl~U ~f:43 Kelly L. Fitch Regulator y Manager M SS 20

American Centrifuge Plant (ACP)-High-Assay Low-Enriched Uranium (HALEU) Demonstration Cascade

Reporting Period of January 1 through June 30, 2024

Overview of Results

During the reporting period of January 1, 2024, to June 30, 2024, enrichment operations for American Centrifuge Operating, LLC (ACO) occurred twice between March and June 2024.

Inventory removal or other maintenance activities were ongoing during the dates that enrichment operations were not occurring.

The information provided within this report provides the total release data, specifically uranium and technetium (if any) amounts and concentrations for ACO gaseous and liquid effluents. There were no quantities of radioactive materials released during the reporting period that are significantly above ACO's design objectives previously reviewed as part of the licensing action.

ACO's total estimated exposure is 1.6 E -05 millirem (mrem). Doses were determined using CAP88 Version 4.1.1 for readings obtained during the reporting period.

Additionally, as requested by U.S. Nuclear Regulatory Commission staff in June 2024, the Hydrogen Fluoride (HF) concentration for the maximumly exposed individual is also provided within this report.

The total release data for the reporting period of January 1 through June 30, 2024, is as follows:

Radionuclide Total Gaseous Releases Total Liquid Releases Unit of Measure 234u 8.94 E-03 1.30 E -01 milliCurie (mCi) 23su 1.lOE-03 5.47 E -03 mCi 23su 8.75 E-03 9.08 E -02 mCi 99Tc 0.00 E +00 - 0.00 E +00 mCi

• 99 Tc lab results were undetectable.

As shown above, the total release data is well below ACO's As Low As Reasonably Achievable goals for both airborne and waterborne radioactive releases as committed within Chapter 9 ofLA-3605-0001, License Application for the American Centrifuge Plant.
