International research

Nagra has been operating the Test Site on the Grimsel pass in the Bernese Alps since 1984. Scientists from all around the world conduct their research in the crystalline rocks of the central Aar Massif. Researchers can access the laboratory year-round. Numerous research projects in all geoscientific and engineering fields provide information on crystalline rock as a potential host formation, on the functioning of the engineered safety barriers and on the transport behaviour of harmful substances in the safety barriers and the rock. The Grimsel Test Site is a platform where know-how is exchanged and where guided tours offer an opportunity for active dialogue with the public and politicians.

We look forward to welcoming you to the Grimsel Test Site.
