Retrievable emplacement experiment with ILW and spent HTR fuel elements in the Asse salt mine
The report presents the essential results of R&D work implemented from 1983 to 1992 on the characterisation of waste packages, the construction and geological exploration of the experimental field on the 800 m level of the Asse salt mine, the geotechnical instrumentation of the test drift and the preparation and instrumentation of the five large boreholes. On the basis of the measured data and investigation results from two thermally heated boreholes in operation since 1989 it is demonstrated that the waste packages could have been emplaced in the three remaining boreholes, similarly equipped, without the retrievability of the packages having been endangered from the geomechanical point of view. Furthermore, it can be inferred from the experience gathered during the four-year period of the precursory tests that during the emplacement test, safe monitoring of the convergence movement of the boreholes would have been ensured.
