Deep boreholes

Deep boreholes provide direct insight into the underground geological environment and its structure. Since 2019, Nagra has been drilling deep boreholes for the detailed investigation of the rock formations in the potential repository siting regions for a deep geological repository, Jura Ost, Nördlich Lägern and Zürich Nordost.

Radioactive waste must be safely disposed of for up to one million years until it no longer poses a hazard. Is it even possible to find a safe solution for such an enormously long time? Nagra’s researchers believe that, yes, this can indeed be done. They rely on geology and on the fact that deep beneath the earth’s surface, time practically stands still.

#Radioactive waste
Volumes of radioactive waste

Switzerland has a manageable amount of radioactive waste. The already existing volume together with the expected future volume could fill two thirds of the historic part of the Zürich train station terminal.

#Search for a site
Site selection process

The search for the most suitable site for a deep geological repository is regulated in the Federal Government’s Sectoral Plan process. Based on this, Nagra will develop a siting proposal by 2022.

#Deep geological repositories
Have repositories been constructed?

Deep geological disposal is an internationally recognised waste management solution. Some countries are already successfully operating low- and intermediate-level waste repositories, and Finland is constructing the first high-level waste repository, which will be ready in the next few years.

Grimsel Test Site

Deep inside the rock of the Grimsel mountain area, over 20 organisations from 12 countries conduct experiments – together with Nagra. Join us on an underground tour. We will gladly show you what is being researched in our rock laboratory.

Mont Terri Rock Laboratory

Mont Terri Rock Laboratory

The Mont Terri Rock Laboratory is an underground research laboratory in Canton Jura where 22 partners from 9 nations work together. As the primary research partner, we will gladly guide you through the rock laboratory, which is managed by swisstopo, the Swiss Federal Office of Topography.

Disposal how?
#Deep geological repositories
Disposal how?

After many years of research by our experts, we have now identified the best rock and possess a robust disposal concept.

Seismic surveys
#Research
Seismic surveys

Seismic measurements provide images of the underground geological environment that can be compared to those obtained from ultrasound. Seismic images capture information on the structure of the rock layers and the presence of geological fault zones. In recent years, Nagra has conducted various 2D and 3D seismic measurement campaigns.
