The geological situation at the Grimsel Test Site (fractured, water-bearing and homogeneous rock zones) offers ideal conditions for carrying out a wide range of experiments. Today, the focus is on the performance and safety of the engineered and geological barriers of a deep repository. Projects at the GTS are investigating disposal concepts on a 1:1 scale. A controlled zone in the laboratory allows radionuclides to be used to test models of the transport of radioactive substances.
