AbstractAbstract
[en] This paper presents simulations of unsaturated groundwater flow and radionuclide transport at Yucca Mountain using the numerical codes TOUGH2 and FEHM. The simulations test the proposed methodology for coupling flow and transport in the upcoming Total Systems Performance Assessment and Viability Assessment (TSPA-VA). The simulations also reveal the sensitivity of transport results to different weighting schemes for hydraulic conductivities used in liquid flux calculations. Results indicate that coupling TOUGH2 and FEHM is a viable method for simulating flow and transport at Yucca Mountain when a modified upstream weighting scheme is used to simulate the flow fields
