Abstract

A series of in-situ radionuclide migration tests are in progress in the Studsvik area on the Swedish east coast. Three well defined flowpaths have been located and characterized using non-sorbing tracers (I-131 and H-3), and one of these pathways have been used for a study of the migration of sorbing elements (Sr-85).

Laboratory sorption studies with Sr-85 have been performed on materials (rock-water) from the same location as the field tests and with variation of parameters not easily varied in-situ (e.g. pH and nuclide concentration).

A fairly good correlation was obtained between retention in natural fractures (field experiment) and laboratory column studies, although the latter were performed on crushed samples of whole rock (retention factors 15 – 30).
