Project of the century: a deep geological repository for Switzerland
For the protection of humans and the environment: With a deep geological repository, we can solve the problem of radioactive waste disposal rather than passing the burden on to future generations.
Our mission is to dispose of radioactive waste once and for all.
We want to solve the problem of radioactive waste now rather than passing the burden on to future generations. The solution to this problem is to construct a deep geological repository. After decades of research, we can now say that we have developed a safe concept for Switzerland and identified an ideal rock. The Nördlich Lägern siting region is the most suitable site for a deep geological repository. We are now ready to undertake the disposal of radioactive waste – together with you.
Which site is Nagra proposing and why? Four questions for Nagra CEO Matthias Braun
What’s new at Nagra?
Nagra proposes “Nördlich Lägern” as the site for a repository
Nördlich Lägern is the safest site for a deep geological repository: here, the rock deep below the surface best confines the radioactive waste for a very long time. Nagra’s investigations demonstrate this. The siting proposal is an important milestone in the project of the century of deep geological disposal.
The surface facility at Haberstal
The surface facility for the deep geological repository is to be constructed in the Haberstal area in the community of Stadel. Nagra has selected this site in collaboration with the region and Canton Zürich.
How do you find a site for a nuclear repository?
Nagra investigated the whole of Switzerland in its search for the most suitable site for a deep geological repository. Potential siting regions were narrowed down until, finally, the three most promising sites were investigated in depth using deep boreholes and seismic surveys. The investigations revealed that all three potential siting regions, Jura Ost, Nördlich Lägern and Zürich Nordost, are suitable. Today, we know that Nördlich Lägern is the most suitable and has the largest safety reserves.
Deep boreholes drilled since 2019
Nagra moves towards construction phase – and continues its research
Nagra has been conducting research since 1972. To keep on learning, this research will continue until repository closure. Following our siting proposal, we will prepare the general licence applications and supporting technical documents and expect to submit these in 2024.
We offer our know-how to interested parties around the world. Our team is continuously broadening its know-how – thanks, in part, to the growing number of scientific staff and the expansion of our pool of experts.
What exactly do we do? We would be pleased to show you!
Nagra operates the Grimsel Test Site, where over 20 organisations from 12 countries conduct experiments. We also carry out research at the Mont Terri Rock Laboratory, which is operated by swisstopo, the Swiss Federal Office of Topography. We would also be pleased to bring our workshop into your classroom or to provide support for school assignments.
