Welcome to the Grimsel Test Site (GTS) Website

The Grimsel Test Site (GTS) located in the Swiss Alps was established in 1984 as a centre for underground Research and Development (R&D) supporting a wide range of research projects on the geological disposal of radioactive waste. 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. International partners from Europe, Asia and North America are working together at this unique facility.

Grimsel's Role in Underground Research & Development

GTS is a research facility 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.
