Compacted clay-based materials are proposed as barriers in disposal strategies for nuclear fuel waste being developed in many countries. Because of their low permeability, diffusion is the principal mechanism of radionuclide transport through these barriers. Here the authors present recommended diffusion coefficients for radionuclides in two clay-based barriers -- the reference buffer and reference backfill -- proposed for use in the Canadian disposal concept for nuclear fuel waste. The authors also discuss how factors like temperature, clay density, and salinity affect diffusion coefficients in these materials.
