The Grimsel Test Site (GTS) was established over 25 years ago as a centre for underground Research and Development (R&D) supporting a wide range of research projects on the disposal of radioactive waste, with international partners from around the world coming to work at this unique location. The GTS provides an environment which is analogous to that of a repository site so allowing the development and testing of equipment, methodology and models under fully realistic conditions.
Grimsel's Role in Underground Research & Development
The GTS is a scientific test site and not a potential repository site; although investigations may utilise a wide range of radioactive tracers, no radioactive waste will be disposed of at the GTS.
