The plant is part of a €500m final disposal facility, construction of which began in June 2019. Construction will be followed by the installation and commissioning of the process systems.
In the facility, spent fuel assemblies will be encapsulated and placed in the bedrock at a depth of about 400 metres.
The facility comprises two sections: the above-ground encapsulation plant for the encapsulation of the spent fuel in canisters, and the final repository deep in the bedrock, with tunnels in which the spent fuel will be placed.
