Clay formations are being world-widely investigated as host medium for the disposal of radioactive waste because of their favourable properties such as very slow transport of fluids and high sorption capacity for most radionuclides. In accordance with the R&D programme defined by the German Federal Ministry of Economics and Technology (BMWi), site-independent basic research on indurated clays for disposal of high-level radioactive waste is in progress in Germany. The German research work has been mostly carried out by participation in international research projects conducted in un-derground research laboratories in clay formations.
