      abstract     = {The current reference concept, i.e. the semihydrostatic
                      emplacement model, for the final disposal of heat-generating
                      high- and intermediate-level waste in deep vertical
                      boreholes in salt provides for completely embedding each
                      individual package in crushed salt. Load diversion by
                      embedding in crushed salt ($\mathbf{LEISA}$ =

                      $\mathbf{SA}$lzgrus) will limit the stacking loads to the
                      packages embedded. On behalf of the Federal Office for
                      Radiation Protection (BfS - Bundesamt für Strahlenschutz),
                      which is responsible for establishing the Gorleben planning,
                      the Research Centre Jülich is engaged in studying
                      theoretically as well as experimentally the applicability of
                      this concept to a future repository (ILW(Q) und HTGR fuel
                      element experimental programme). Two test stands with
                      different geometrical dimensions were designed,
                      manufactured, instrumented and put into operation for
                      simulating a repository borehole. The pressure distributions
                      were measured in the test stands and compared with those
                      calculated, varying all decisive parameters. According to
                      the measurements performed in this test programme, the
                      predictions of the semihydrostatic model for a rough
                      borehole wall surface examined in both test stands are in
                      very good agreement with the experiments. The deviations
                      between theory and experiment found for a smooth wall
                      surface are presumably due to a still too unspecific
                      determination of those crushed-salt parameters which are
                      incorporated in the model calculations. The investigations
                      carried out to date may be summarized as follows: load
                      diversion by embedding in crushed salt is a highly efficient
                      tool for limiting the stacking loads in vertical repository
                      boreholes filled with crushed salt and waste packages.},
