Abstract
In order to improve the final concept for HAW disposal in salt formations the complete technical system of an underground repository is to be tested in a one-to-one scale test facility. Such a facility has been established in the Asse salt mine (FRG). Thirty canisters containing glass blocks with highly radioactive radionuclides Cs-137 and Sr-90 will be placed in six boreholes located in two test galleries A and B at the-800 m level in the Asse salt mine. The research programme is aimed at the observation and measurement of the interaction between the canisters with the radioactive content and the rock salt. Because of the requirement to retrieve the canisters when necessary during the five years` test period, the canisters are loaded in boreholes lined with tubes. Thermally induced pressure stresses in the salt will cause the tube to deform. The canister will be retrieved when the deformation exceeds a maximum set value. The Netherlands Energy Research Foundation (ECN), Petten, Netherlands, has designed special canister guiding systems for loading and unloading the boreholes together with a monitoring system that continuously monitors the gap between the canisters and the inner wall of the tube. This progress report is the tenth of
