AbstractAbstract
[en] In order to predict the diffusion of actinides and fission products through a backfill mixture of sand and clay from a high-level waste repository, the diffusion of the actinides 241Am, 239Pu, 237Np and 233U and the fission products 134Cs, 131I and 99mTc have been measured in a mixture of 90% silica sand-10% bentonite (MX-80, Wyoming bentonite). The sand-bentonite mixture was compacted to a density of 2000 kg/m3. The water phase used was an artificial groundwater representative of Swedish deep granitic groundwater (pH∼8, I∼0.01). The apparent diffusivity is in all cases slightly higher than in pure clay. (author)
