Terradura

To protect future generations. Experts worldwide agree that a deep geological repository is the safest option for the long-term disposal of radioactive waste. This is why Swiss legislation requires a repository located within its borders. The Terradura project of the century is the key to realising this plan, protecting humans and the environment in the long term.

In the Zürcher Unterland (the northern part of Canton Zürich). The surface facilities will be constructed in the Haberstal area of the community of Stadel.

Terradura refers to the entire infrastructure and includes the surface facilities, the shafts leading below ground and the deep geological repository with its underground emplacement drifts and caverns.

A repository is a facility built for the purpose of safely disposing of radioactive waste. Aside from the technical infrastructure, the rock formations surrounding the repository are also important components. The underground disposal zone will be constructed in a thick layer of rock called the Opalinus Clay. This clay-rich rock is the most important part of the solution ensuring the safe containment of radioactive waste over long periods of time.

Nagra submitted the general licence application for Terradura in 2024. This is currently being reviewed by the authorities. The Federal Council and Parliament will then decide on granting the licence. In the event of a national referendum, the electorate will have the final say. Construction is scheduled to begin in the mid-2030s.
