Calculations have been made at the Center for Nuclear Waste Regulatory Analyses (CNWRA) to assess the importance of the various driving mechanisms of heat and mass transport at a high-level nuclear waste (HLW) repository located in the unsaturated zone. Scoping measurements of the relative importance of vapor movement by buoyancy forces and by advective forces have been made for a proposed laboratory-scale experiment to be conducted at CNWRA and for a proposed field-scale heater experiment by U.S. Department of Energy (DOE) at Fran Ridge. These scoping measurements are made using a set of dimensionless terms assembled for this analysis. Numerical simulations of the same laboratory- and field-scale experiments are made using VTOUGH. These calculations will be used to predict (and design in the case of the laboratory-scale experiment) the redistribution of moisture in response to the imposition of heat on the two experiments.
