Abstract: The emplacement of spent fuel elements from high-temperature reactors (HTR) in deep vertical boreholes in a salt repository is one favorable technique for the disposal of these wastes in Germany. A retrievable emplacement experiment in the abandoned Asse salt mine with spent fuel elements is being prepared. In parallel, the borehole disposal technique itself is being developed. Out of various alternatives, the emplacement of fuel element packages in vertical unlined boreholes, backfilled with crushed salt, seems to be most favourable.
