Research on the safe disposal of radioactive waste
The long-term, safe disposal of radioactive waste relies on intensive research work, much of which is conducted in rock laboratories.
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.

Underground rock laboratory experiments contribute to the safety of a future deep geological repository for radioactive waste.

What further insights does Nagra need in order to propose the most suitable siting region for a repository by 2022?
