The Development of Bentonite Gap Filling for High-Level Waste Disposal
Original language description
The main aim of the repository disposal system is to prevent the migration of radionuclides into the biosphere. It is expected that the natural rock barrier as well as the engineered barrier elements of the system will guarantee the safe disposal of radioactive waste for the required time period. Bentonite clay has proven to be particularly suitable in this respect thanks to its sealing properties (very low permeability in the case of both water and gases). The buffer, which makes up a crucial part of the geotechnical barrier, surrounds the container in the disposal well. The main requirements in terms of the geotechnical properties of the buffer material consist of very low hydraulic conductivity (max 10-12m/s), high swelling ability (Ssw> 1MPa), rheological stability, high plasticity, and good thermal conductivity. The article presents the results of research into the most important geotechnical properties of Czech Ca-Mg bentonites and provides an outline of both the design of the te
