DEVELOPMENT OF COMPUTER CODES AND PERFORMANCE OF MODEL CALCULATIONS ON THE THERMOMECHANICAL INTERACTION OF ROCK SALT WITH THE BSW BOREHOLE LINING OCCURRING IN THE NEIGHBOURHOOD OF A HIGH LEVEL WASTE DEPOSITORY
The principal objectives of the work are the development of computer codes with suitable material laws for rock salt and to perform model calculations on the thermomechanical phenomena in the near field of a radioactive waste repository. In particular the work was dealing with the following subjects: - Comparison of the computational capabilities of the finite element codes ADINA and MAUS (new version) by model calculations for the temperature test field 3. - Thermally induced convergence rates of boreholes in a high level waste (HLW) repository. - Investigation of the contact between salt and waste containers or borehole liners, and of the resulting pressure rise. - Investigation of the effect of inhomogeneities (anhydrite layers) in rock salt on the stress - strain field around the borehole in a HLW repository. - Development of a material model for backfill material and performance of model calculations on the convergence of backfilled storage rooms or tunnels in rock salt. - Development of a new version of the computer code MAUS by the Institut fuer Elektrische Anlagen und Energiewirtschaft of the RWTH-Aachen.
