A near-field hydrothermal model to predict the temperature and saturation variations in the vicinity of heat-generating waste packages is presented in this paper. Various suites of thermo-hydrologic simulations were performed using FEHM and TOUGH2, with three areal power densities and two infiltration rates. The thermal and saturation predictions from both of these codes at various time levels were compared in order to benchmark their performance in terms of simulating near-field multi-phase fluid flow and heat transport. Results from the current near-field hydrothermal analyses indicate that liquid saturations near the waste package are significantly different from the average repository saturations predicted by repository scale hydrothermal models.
