LES-19-034-NRC ENCLOSURE 1 Semi-Annual Radiological Effluent Release Report for July 1, 2018 through December 31, 2018

URENCO USA: Report of Radioactivity in Effluents: Liquid & Air: July 2018 - December 2018 There were no releases to the public during the reporting period that exceeded regulatory requirements.

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 concentrations.

In liquid effluent, the concentrations of isotopic uranium was either below the Minimum Detectable Concentration (MDC) or less that 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 that 10% of values listed in 1 O 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" dated December 1996.

@_iENCOUSA

URENCO USA: Report of Radioactivity in Effluents: Liquid & Air: July 2018 - December 2018 There were no releases to the public during the reporting period that exceeded regulatory requirements.

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 concentrations.

In liquid effluent, the concentrations of isotopic uranium was either below the Minimum Detectable Concentration (MDC) or less that 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 1 O 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 that 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" dated December 1996.

@ENCOUSA

URENCO USA: Report of Radioactivity in Effluents: Liquid & Air: July 2018 - December 2018 There were no releases to the public during the reporting period that exceeded regulatory requirements.

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 concentrations.

In liquid effluent, the concentrations of isotopic uranium was either below the Minimum Detectable Concentration (MDC) or less that 10% of values listed in 10 CFR 20, Appendix 8, 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 Usted in 1 O CFR 20, Appendix 8, 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 that 10% of values listed in 10 CFR 20.1301, 10 CFR 20.1302, and 1 O 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" dated December 1996.
