Description
The wastes will be emplaced in a deep geological repository (depth approx. 650 m) in a subhorizontal claystone formation. In the proposed repository, carbon steel canisters containing either SF or HLW are emplaced coaxially within a system of parallel tunnels that are constructed in the centre of the formation and aligned along the dip direction. The tunnels are backfilled with compacted bentonite. ILW is emplaced in larger-diameter concrete-lined tunnels, with a cementitious backfill.
