The Swiss repository is called «Terradura»
Im Online-Voting sprachen sich fast 40 Prozent dafür aus, das geologische Tiefenlager der Schweiz «Terradura» zu nennen. Insgesamt gingen über 3000 Namensvorschläge aus der Schweizer Bevölkerung ein.

«Terradura - Swiss Deep Geological Repository»: This is the name of the repository project of the century as of today. The term prevailed in the online vote against four other name suggestions. Originally, over 3,000 name suggestions were submitted by the Swiss population.
National participation process
In recent weeks, Switzerland has voted on the name that will characterize future communication on the Swiss deep geological repository. The «Swiss Deep Geological Repository Naming Forum» organized this national participation process.
Interested parties from all parts of the country were able to submit their ideas online. The Name Forum jury selected five of the more than 3,000 suggestions submitted for the final online vote.
The candidates were: ATLASuisse, Peradina, Stadelnova, Soluterra and Terradura.
Voting results
- Terradura 39.4 %
- ATLASuisse 23.4 %
- Soluterra 17.8 %
- Peradina 12.5 %
- Stadelnova 6.9 %
The term terradura comes from «terra dura», which means «solid earth».
It had already been decided that the chosen name would bear the descriptive addition «Deep Geological Repository Switzerland».
Easy access to a challenging project
The deep geological repository for radioactive waste is a project of the century and affects the region around Stadel in the Zurich Unterland, Switzerland as a whole and, in the long term, future generations.
A name is an intuitive entry point - easy access to a challenging project long before technical or political details take center stage. «The process shows that participation is successful when access is easy,» says Martin Künzi, representing the naming forum. «A name creates an initial point of contact with a topic that is otherwise difficult to access.»
How the repository got its name
Between August and September, 3,395 name suggestions were received. The Swiss Repository Names Forum acted as a jury and examined all ideas on the basis of the criteria published in advance: Comprehensibility, conciseness, depth of meaning and viability in several national languages. The jury members also provided feedback from their respective networks. In a consensus-oriented process, five names emerged as having the greatest potential to provide appropriate support for the project in Switzerland: ATLASuisse, Peradina, Soluterra, Stadelnova and ’Terradura«.
The subsequent voting phase was used throughout Switzerland - with greater participation from German-speaking Switzerland (85 %), but noticeable votes from French-speaking Switzerland and Ticino (15 %). The most popular proposal «Terradura» will be used in future communications, supplemented by the descriptive addition «Swiss deep geological repository».
The name Terradura will be gradually introduced into communication over the coming weeks and months. The naming process is now complete - the public, technical and social discourse on the Swiss deep geological repository continues.
