ATTN: Document Control Desk Director Office of Nuclear Material Safety and Safeguards U.S. Nuclear Regulatory Commission Washington, D.C. 20555-0001 Louisiana Energy Services, LLC NRC Docket No. 70-3103

Subject:

Amended Semi-Annual Radiological Effluent Release Report for July 1, 2021 through December 31, 2021

Reference:

1) UUSA Semi-Annual Radiological Effluent Release Report for July 1, 2021 through December 31, 2021, dated 2/25/2022 (LES-22-046-NRC, ML22060A092)

Pursuant to 10 CFR 70.59, Louisiana Energy Services, LLC, also dba URENCO USA, herewith submits the subject report. Reference 1 reported the quantities released of licensed principal radionuclides in liquid or gaseous form, to uncontrolled areas for the July 1, 2021 through December 31, 2021 reporting period was submitted on February 25th of this year.

The previous Semi-Annual Radiological Effluent Release Report was missing the sampling data for 1001-562-1MA1 gross alpha and gross beta for Quarter 3, 2021 due to a software error. This data was recalculated by the contractor and the results have been included in the Enclosure 1, Amended Semi-Annual Radiological Effluent Release Report for July 1, 2021 through December 31, 2021. This amended report does not change the outcome, there were no releases to the public during the reporting period that exceeded regulatory requirements, and detected isotopic uranium activities were comparable to pre-operational activities.

Should there be any questions regarding this submittal, please contact Barry Love, Licensing Specialist at 575-394-4482.

Respectfully, Chris Schwarz Licensing and Performance Assessment Manager

ENCLOSURE 1 Amended Semi-Annual Radiological Effluent Release Report for July 1, 2021 through December 31, 2021

URENCO USA: Report of Radioactivity in Effluents: Liquid & Air: July 2021 - December 2021 There were no releases to the public during the reporting period that exceeded regulatory requirements, and detected isotopic uranium activities were comparable to pre-operational activities. No dose assessment was performed because the maximum potential dose directly at the point of gaseous and liquid effluent discharge points were acceptable. The potential maximum doses directly at the discharge points for both liquid and gaseous effluent were shown to be less than 10% of the radionuclide concentration dose.

In liquid effluent, the concentrations of isotopic uranium were either below the Minimum Detectable Concentration (MDC) or less than 10% of values listed in 10 CFR 20, Appendix B, Table 3, Releases to Sewers (Table 1-1).

In gaseous effluent, the gross uranium activity was either below the Minimum Detectable Activity (MDA) or less than 10%

of values listed in 10 CFR 20, Appendix B, Table 2, Effluent Concentrations - Class D Air for U234, U235, and U238.

The concentrations of isotopic uranium in gaseous effluent was either below the Minimum Detectable Concentration (MDC) or less than 10% of values listed in 10 CFR 20.1301, 10 CFR 20.1302, and 10 CFR 20.1101(d), as described in NRC Regulatory Guide 4.20 Constraint on Releases of Airborne Radioactive Materials to the Environment for Licensees other than Power Reactors Revision 1 dated April 2012.

Sampling data was not reported for gross alpha and gross beta for Quarter 3, 2021 due to a software error. The data was recalculated by Mirion Technologies and the results is the amended SARERR for this period.
