Disposal of High-Level Nuclear Waste in Rock-Salt. A Comparison of Temperature Increases Calculated at ECN (Energieonderzoek Centrum Nederland)-Petten, RWTH (Rheinisch-Westfaelische Technische Hochschule Aachen)-Aachen and THD (Delft University of Technology)-Delft

摘要

Disposal of high-level nuclear waste in rock-salt formations will cause temperature increases. These temperature increases have been calculated with different computer programs. In this report temperature increases, calculated with computer programs of ECN (Netherlands Energy Research Foundation) and RWTH (Rheinisch-Westfalische Technische Hochschule) are compared with temperature increases, calculated with the computer program of THD (Delft University of Technology). The three computer programs differ on subjects such as mathematical procedure, correction for the temperature dependencies of the thermal properties of rock-salt, physical description of the disposal region, disposal pattern. Because of these differences between the computer programs a comparison of results is useful.
