URENCO USA: Report of Radioactivity In Effluents: Liquid & Air: July 2020 - December 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 erther below the Minimum Detectable Concentration (MDC) or less than 10% of values listed m 10 CFR 20, Appendix B, Table 3, "Releases to Sewers" (Table 1-1).
In gaseous effluent, the gross uranium actIvrty 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 m 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 Apnl 2012.
