Flow of ground water around buried waste
Analyses by Chambre and Andersson et al. of the mass transfer of radionuclides from waste packages into surrounding backfill and rock have considered diffusive-convective transport of dissolved species in ground water in the rock but have assumed no flow of ground water through the backfill. Although in some geologic repositories the ground water flow is expected to be so small that radionuclide release is controlled by molecular diffusion, to assess the possible contribution of backfill water flow to radionuclide release it is necessary to analyze the local flow field in layers of backfill and rock surrounding a waste package. Here the authors illustrate some results from a potential-flow theory developed by Chambre to predict the steady flow stream lines, equipotential contours, and flow velocities in backfill and porous rock surrounding a spherical or cylindrical waste package.
