Bentonite is a key material for the construction of Engineered Barrier Systems (EBSs) in
deep geological repositories (DGRs) for radioactive waste. Modelling of gas migration in …

Host rocks, as the final impediment to waste migration, play a significant role in the nuclear
waste repositories. Modelling of gas migration in saturated host rocks as well as its coupled …

Dilatancy controlled gas flow is characterized by a series of gas pressure-induced dilatant
pathways in which the pathway aperture is a function of the effective stress within the solid …

Large quantities of gas can be produced during the lifespan of a deep geological repository
(DGR) due to several processes that may affect the integrity of the host rock. Therefore …

Dilatancy-controlled gas flow is a dominant process of gas migration in saturated bentonite.
In this paper, a fully coupled hydro-mechanical model, which incorporates the concepts of …

Abstract Geological Disposal Facilities (GDF) for radioactive waste will generally rely on clay-
rich materials as a host geological formation and/or engineered barrier. Gas will be …

Deep geological disposal is the preferred solution for radioactive waste management in
many countries, including Belgium, where the Boom Clay is one of the potential candidate …

In the geological disposal of high-level radioactive waste in argillaceous rocks, studying the
barrier integrity after gas transport and the pathway closure thanks to self-sealing capacity is …

During recent decades, argillaceous sedimentary formations have been studied as potential
host formations for the geological disposal of long-living and heat-emitting radioactive waste …

Claystone is considered as a potential host rock for radioactive waste disposal at great
depth in many countries. Considerable quantity of gas can be generated in a deep …
