Summary:A three-dimensional, finite-element code, called MOTIF, has been developed to simulate the coupled processes of fluid flow and heat transport on a regional scale. Significant hydrogeological features such as major fracture zones may be modeled as planes embedded in a porous matrix. The code has been verified by comparison with analytical solutions or other published numerical solutions. In a major validation exercise, the code has given reasonable predictions of the hydrogeological impact of the excavation of the Underground Research Laboratory in a granitic pluton near Lac du Bonnet, Manitoba. A three-dimensional particle-tracking code is being developed to calculate radionuclide pathways based on ground-water velocity distributions predicted using MOTIF. Detailed hydrogeological models will be constructed for three major research areas within the Canadian Shield. The computer codes will then be used to estimate the characteristics of potential radionuclide pathways from a hypothetical repository at each site. This information will subsequently be used in the environmental and safety assessment of the concept.—Modified report abstract.
