Technical visits to Swiss URLs

Technical visits to Swiss Underground Rock Laboratories

On September 28, two optional visits to the Swiss Unterground Rock Laboratories can be organised.

  • The Mont Terri Rock Laboratory is situated to the north of St-Ursanne in the canton of Jura, around 300 m underground in the Opalinus Clay formation. It is operated by swisstopo. 16 international partners participate in research activities.

  • The Grimsel Test Site is located at an altitude of 1730 m above sea-level in the granitic formations of the Aar Massif. The GTS was established in 1984 as a centre for underground Research and Development supporting a wide range of international research projects on the geological disposal of radioactive waste.

The guided tours are free of charge for conference participants and accompanying persons. For logistical reasons, only one of the sites may be visited in one day.
