Time-Dependent Nuclide Transport Through Backfill into a Fracture

C. H. Kang / P. L. Chambre / W. W. L. Lee / T. H. Pigford

This paper presents a transient analysis of radionuclide transport through backfill into a fissure. This report considers a waste canister surrounded by backfill in a borehole intersected by a fracture, in water-saturated rock. Radionuclides are released at a constant concentration C/sub s/ at the waste surface into the backfill. Ground water flows in the fissure. We assume no ground-water flow in the backfill, so that radionuclide transport through the backfill is controlled by molecular diffusion. 3 refs., 2 figs. (ERA citation 13:000340)
