Content: The sorption and diffusion parameters of Ba and Cs were determined from laboratory experiments in the conditions of the Olkiluoto and Grimsel in situ test sites as starting parameters for the safety case analyses of the final disposal of spent nuclear fuel. The sorption of Cs and Ba on biotite was also studied with molecular modelling to understand the sorption processes of the radionuclides on a molecular level. Additionally, the porosity structures of the rocks were studied with C-14-PMMA autoradiography method to assess the migration routes in different rocks. The sorption and diffusion results have been modelled with PhreeqC and the work is still ongoing. The results will be utilized in the analysis of the in situ diffusion experiments conducted in the Olkiluoto and Grimsel test sites.
