Abstract

In this study, a systematic analysis of cesium through crushed granite (0.297–0.840 mm) was constructed where synthetic groundwater and seawater were employed as the liquid phase. To build such models, multi-stage advection–dispersion column tests were conducted in order to determine the major transport processes and the calibration/validation of the hypothesized reactive transport models. The experimental breakthrough curves (BTCs) for HTO and Cs were both matched with their corresponding numerical BTCs by adjusting reaction and transport parameters such as forward or backward reaction rate constants (k_f or k_b), dispersivity (α), and porosity(θ).
