© 2024 Urenco USA Inc. 2 URENCO USA: Report of Radioactivity in Effluents: Liquid & Air: January 2024 - June 2024
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, Rel eases 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 Concentrati ons - 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 dated December 1996.
The Centrifuge Test and Post Mortem Building resumed functionality in November 2023. The initial effluent filter was installed in November 2023 upon system start up and was removed in February 2024, upon which subsequent filters were collected monthly.
