The effective isolation of high-level radioactive waste emplaced in deep geological repositories is based upon the multi-barrier principle (the KBS-3V concept). It is assumed that bentonites and montmorillonitic clays, which will be used as the buffer and backfill material, will provide for the stabilisation and mechanical protection of the container, limit advective transfer, reduce the migration of radionuclides and microbial activity and be resistant to chemical transformation and alteration.
Extensive research is currently being performed on Czech bentonites and montmorillonitic clays. Indeed, one of the most important tasks for the period 2018 – 2025 will be to verify whether it will be feasible to employ bentonites extracted from Czech deposits (Rokle, Černý Vrch etc.) as the buffer and backfill materials for the future Czech DGR.
Therefore, a number of laboratory and in-situ experiments are underway at two Czech underground laboratories with different rock environments (the Josef URC and the Bukov URF).
