A voluntary course dealing with safe radioactive waste disposal. Classification of radioactive waste according to various aspects, principle of a multi-barrier system, vertical and horizontal way of disposal. Requirements for the construction of the deep geological repository. Natural analogues. Natural and engineered barriers. Bentonite - basic material of the geotechnical part of the engineered barrier, requirements for its properties. Interdisciplinarity of the research, laboratory and "in-situ? research (underground laboratories), physical modelling (Mock-Up models). Practical laboratory lessons (plasticity of bentonites, swelling pressure measurements, permeability measurements of compacted samples, strength and deformation properties, thermophysical properties). Practical lesson at the Josef underground laboratory (http://ceg.fsv.cvut.cz) - construction of large in situ physical models).
