According to Swiss regulations, low and intermediate level wastes (L/ILW) should be stored in deep geological repositories excavated about 300 to 400 meters below the ground surface, in suitable rock formations. The materials used for the construction of t ...
The interactions of trivalent lanthanides and actinides with secondary mineral phases such as calcite is of high importance for the safety assessment of deep geological repositories for high level nuclear waste (HLW). Due to similar ionic radii, calcium-be ...
For the characterization of gas migration through a low-permeability clay host rock for deep underground repositories, a comprehensive understanding of the relevant phenomena of gas and fluid flow through low-permeability clay is required. The National Coo ...
Compacted MX-80 bentonite is a potential backfill material in radioactive-waste repositories. Pore space in MX-80 has been the subject of considerable debate. 3D reconstructions of the pore space based on tomographic methods could provide new insights into ...
Deep geological repositories are considered as suitable solutions for the disposal of high level nuclear wastes. In several repository concepts (e.g. in Spain and Switzerland), bentonites are selected as the main component of the engineered barrier to be p ...
In the context of nuclear waste disposal in clay formations, laboratory and in situ simulation experiments were performed to study at reduced scale the Excavation Damaged Zone (EDZ) around tunnels in the indurated Opalinus Clay at Mont Terri, Switzerland. ...
A deep geological repository involving a multi-barrier system constitutes one of the most promising options to isolate high-level radioactive waste from the human environment. In order to certify the efficiency of waste isolation, it is essential to unders ...
A proper evaluation of the perturbations of the host rock induced by the excavation and the emplacement of exothermic wastes is essential for the assessment of the long-term safety of high-level radioactive waste disposals in clay formations. The impact of ...
In recent years, the complexity of geomechanical problems has greatly increased as a result of the demand for new and intricate types of applications. Experimental characterization and numerical prediction by means of multiphysical approaches are in that c ...
