A series of emplacement tunnels will be constructed deep underground to house the HLW and SF canisters. An example layout for a SF/HLW repository and an operational study (surface facilities, emplacement tunnels, pilot tunnels, rock laboratory, access ramp, ventilation tower, etc.) has been developed by Nagra.

The images below are stills taken from the Nagra Die LÖSUNG DVD which outlines the procedures and methods for the remote emplacement of a HLW / spent fuel canister. Please see the Media & Downloads section for additional videos on geological emplacement.
