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 …

This paper presents a novel strain-dependent water retention model for improved predictive
modelling of localized gas flow in bentonite. The proposed model uses fundamental material …

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 …

Self-sealing of fractures in the indurated Callovo-Oxfordian (COX) and Opalinus (OPA)
claystones, which are considered as host rocks for disposal of radioactive waste, was …

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 …

To ensure the long-term safety and performance efficiency of a deep geological repository
for disposal of high-level radioactive waste, understanding and assessment of gas migration …

In the context of repositories for nuclear waste, understanding the behavior of gas migration
through clayey rocks with inherent anisotropy is crucial for assessing the safety of geological …

In a repository for radioactive waste hosted in a clay formation, hydrogen and other gases
may be generated due to the corrosion of metallic materials under anoxic conditions, the …

Phase field (PF) method is incorporated into the coupled hydromechanical (HM) model in
this paper to simulate the preferential gas flow in saturated bentonite. In order to account for …

The present paper gives an overview of the GeomInt project “Geomechanical integrity of
host and barrier rocks—experiment, modelling and analysis of discontinuities” which has …
