Subject:

Semi-Annual Radiological Effluent Release Report for January 1, 2020 Through June 30, 2020 Pursuant to 10 CFR 70 .59, Louisiana Energy Services, LLC, also dba URENCO USA, herewith submits the subject report. Enclosure 1 specifies the quantities released of licensed principal radionuclides in liquid or gaseous form, to uncontrolled areas.

UUSA sampled domestic wastewater on July 22, 2020 and this was outside of the reporting period of January 1, 2020 through June 30, 2020. This deficiency has been documented in UUSAs corrective action program as EV 138892. UUSA considers the July 22 nd sample results to be representative of the radionuclides discharged during the reporting period . Additionally, UUSA recognizes that this report was not submitted within 60 days of July 1 per 10 CFR 70.59. This has been documented in our corrective action program as EV 140278.

Should there be any questions regarding this submittal , please contact me at 575-394-5257.

URENCO USA: Report of Radioactivity in Effluents: Liquid & Air: January 2020 - June 2020 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 NRG Regulatory Guide 4.20 "Constraint on Releases of Airborne Radioactive Materials to the Environment for Licensees other than Power Reactors" dated December 1996.
