Description

The potential site of the SF/HLW/ILW repository is in the Zürcher Weinland of northern Switzerland, close to the Rhine river section between Neuhausen and Rheinau. The repository is located in the Opalinus Clay (reference depth of the repository 650 m below ground). Separate emplacement tunnels for SF/HLW and ILW are constructed in the centre of the clay layer and aligned along the dip direction. The design includes the main repository, a pilot repository for monitoring purposes and a test facility (rock laboratory). Access to the system of tunnels is provided, during construction and operation, by a spiral ramp. A vertical ventilation shaft is also foreseen.
