Abstract
The diffusion properties of concrete and of buffer and backfill materials to be used in decommissioning waste repositories were studied experimentally. The properties were determined by tracer experiments using Cl-36 and tritium (HTO) as tracers. The measurements comprised diffusivity and retardation capacity determination by the through-diffusion method and the saturation-leaching method, porosity determination by the water saturation method. Two types of crushed rock backfills, two types of crushed rock-bentonite buffers and one type of concrete were studied. Two water types, saline and non-saline, from the future repository sites were used as waters. The report presents the measured apparent and effective diffusivities, retardation capacities and porosities. (9 refs., 27 figs., 8 tabs.).
