The underground laboratory of Mount Terri is a research laboratory under the direction of swisstopo (federal office of topography). 15 research partners from 10 countries are studying the characteristics of argillaceous rocks on the basis of opalinus clay. Formations of this type are being studied for suitability for the construction of geological depots for nuclear waste. The underground laboratory is used for research only. It is strictly forbidden to store radioactive waste there, not even temporarily.
