Preparation for final disposal of radioactive wastes has been done as part of a national program since 1993. The Central Nuclear Financial Fund and the Public Limited Company for RadioactiveWaste Management (Puram) have been established to coordinate organizations and activities for all tasks in connection with nuclear waste treatment. The project started with a geological screening in order to find the most suitable formation for the radioactive waste disposal. The selected potential host rock is a granite complex in the Mórágy Granite Formation in the south-western part of Hungary, close to the village of Bátaapáti. The goal of this paper is to present the newest modeling results of the Excavation Damaged Zones around the Bátaapáti radioactive waste repository. The following zones are thoroughly investigated and modeled in both 2D and 3D: EdZ: Excavation Disturbed Zone; EDZ: Excavation Damaged Zone and HDZ: Highly Damaged Zone. These Excavation Damaged Zones (EDZs) are very important for understanding the hydromechanical and geomechanical behavior. Therefore the EDZs were analyzed by hydrogeological, filed- survey, geophysical and Borehole Television (BHTV) methods. Our modeling was using both high number of laboratory rock tests and the field measurements. The correlation between the computed and measured values, were verified.

The Displacement Discontinuity Method (DDM), FROCK, is used in this investigation to model experimental observations on pre-cracked specimens of gypsum. In these experiments two fractures, which were either both open or closed, were placed through the thickness of the specimens, and detailed observations of the cracking process were performed as the specimens were loaded in uniaxial compression. The following aspects are studied for both open and closed fractures: 1) crack initiation stress; 2) direction and propagation of the new cracks; 3) type of coalescence and stress at which it occurs. Modeling is done considering the actual size of the specimens. Relations between the direction of initiation for each type of crack, the orientation of the initial fractures, and the type and coalescence are established. In addition, comparisons between results from experiments and predictions from the model are presented. The numerical results are in agreement with the experiments. LA - English DB - MTMT ER -
