Abstract

This study is focussed on the modelling of radionuclide migration in the geosphere outside a salt rd dome in which a repository is located. Migration is only feasible after contact of groundwater with deposed waste. This might happen at short or at long term. Although many precautions during the operational period will be taken to exclude the risk of water intrusion and to limit the consequences, an intrusion in the postclosure phase can never completely be excluded. Moreover, in the long run, groundwater might contact disposed waste after slow suberosion of rock salt by moving groundwater. The study has two main objectives: - to develop a computer model, taking into account density (saline brines), sorption, temperature, inhomogeneities, etc., for the radionuclide migration in the underground after release from a salt dome repository. - to achieve a better understanding of the influence on the modelling results of the existing uncertainties in the geological, hydrological and geochemical input data. A subobjective is a more specific identification of relevant data which will have to be collected in future.
