Predicting the partition coefficient of strontium-90 and uranium in an alluvial aquifer: From the laboratory scale to the field scale
Abstract
This study demonstrates the robustness of an approach called component additivity (CA), which was developed to predict the partition coefficient (K D ) of strontium-90 and uranium in an alluvial aquifer near nuclear facilities across scales, from the laboratory to the field. CA uses two thermodynamic sorption models requiring only the proportion of reactive solid phases (illite, smectite, and ferrihydrite) and pore water chemistry. First, the reliability of the approach was first evaluated at the laboratory scale by comparing the simulated K D values with experimental sorption data acquired from four solid samples in their raw and carbonate-free
