Mont-Terri underground laboratory | Switzerland

An international project

The Mont-Terri underground laboratory, managed by Swisstopo, is a research establishment near Saint-Ursanne in the canton of Jura in Switzerland. The laboratory, accessed by the Mont-Terri road tunnel, is conducting research into opalinus clay, the potential host rock for the planned storage of nuclear waste in Switzerland, in a deep geological layer.

Partners from Europe, the United States, Canada and Japan have come together to form the Mont-Terri Consortium to finance the programme and share its results.

Nearly 50 experiments are being conducted there using a large number of sensors spread over more than 800 boreholes, generating a large quantity of valuable data.
