It is very important to explain the sorption mechanisms of relevant radionuclides, for the performance assessment of geological disposal and for the technical development of engineering barrier system. In the previous studies 1993-1996, these tests were carried out to understand sorption mechanism of SN; -solubility tests -sorption tests onto bentonite, pure montmorillonite, A-FEO(OH) -extraction tests from these minerals -sorption tests onto tuff as a next step, these tests were carried out ragarding SN in this study; -diffusion tests (in-diffusion) -tests for effect of SN concentration and ionic strength on sorption -sorption tests onto granite -tests for effect of coexistent ions on solubility
