The International Mont Terri Rock Laboratory is situated near the small town of St-Ursanne in the canton of Jura. At the Rock Laboratory, a total of 22 partners from Switzerland, Belgium, Germany, France, Japan, Canada, Spain and the US carry out research into the properties of Opalinus clay, which is a potential host rock for the storage of radioactive waste.
However, radioactive waste is never stored at St-Ursanne. The Rock Laboratory is operated by swisstopo, the Swiss Federal Office of Topography. ENSI participates in the Rock Laboratory with its own research projects.
Interested groups can register for a guided tour of the Mont Terri Rock Laboratory. The recommended group size is 10 to 40 persons. The tours are free of charge, and usually last around two and half hours. They are carried out during the working days each morning and afternoon. The programme comprises an introduction in the lecture theatre (about 45 minutes) and a guided tour of the Rock Laboratory (about 90 minutes). Minibuses transfer participants to the Rock Laboratory.
We advise you to register at least one month before the tour date you would like. You can find the registration form here.
We look forward to your visit.
