Together with national and international partners, we carry out:
- Experiments in underground rock laboratories
- Investigations of comparable natural procedures and conditions, so-called natural analogues
- Laboratory studies
These activities are conducted independently of the potential repository site.
What is investigated in a rock laboratory?
An underground rock laboratory allows scientists to carry out experiments directly in the rock under realistic conditions. This also includes experiments on a 1:1 scale. Researchers investigate the rock and its behaviour and analyse how the engineered safety barriers work. They also assess the transport behaviour of toxic substances in the safety barriers and in the rock. All these experiments provide important information for the construction of a deep geological repository and its long-term safety.
Nagra has its own rock laboratory on the Grimsel Pass and is involved in the Mont Terri Rock Laboratory in Canton Jura, which is led by the Federal Government (swisstopo). In both rock laboratories, Nagra works with leading international specialists.
- Underground rock laboratory experiments contribute to the safety of a future deep geological repository for radioactive waste.
