Groundwater Monitoring Data and Screening Radionuclide Transport Modeling Analyses for the Uranium Mill Tailings at the Pridneprovsky Chemical Plant Site (Dneprodzerzhinsk, Ukraine)
This paper presents results of groundwater monitoring and screening modeling studies carried out in 2008–2010 for the uranium production legacy site Pridneprovsky Chemical Plant (Dneprodzerzhinsk city, Ukraine). The simulated offsite radiological risks caused by groundwater pathway are estimated to be low because of the long travel time to discharge contours (hundreds-thousands of years) and large dilution of contaminants in the Dnieper River system. The preliminary recommendation is stabilization and storage of tailings sites in-situ. Further groundwater monitoring and risk assessment studies are opportune.
