Hollow cylinder simulation experiments of galleries in Boom Clay formation
In the context of nuclear waste disposal in clay formations, laboratory experiments were performed to study at reduced scale the Excavation Damaged Zone (EDZ) induced by the construction of galleries in the Boom Clay formation. For this purpose, thick-walled hollow cylindrical samples were subjected (after recovery of in-situ stress conditions) to a decrease of the inner confining pressure aimi...
متن کاملOn the Thermal Consolidation of Boom Clay
When a mass of saturated clay is heated, as in the case of host soils surrounding nuclear waste disposals at great depth, the thermal expansion of the constituents generates excess pore pressures. The mass of clay is submitted to gradients of pore pressure and temperature, to hydraulic and thermal flows, and to changes in its mechanical properties. In this work, some of these aspects were exper...
متن کاملInvestigating the pore-water chemistry effects on the volume change behaviour of Boom clay
The Essen site has been chosen as an alternative site for nuclear waste disposal in Belgium. The soil formation involved at this site is the same as at Mol site: Boom clay. However, owing to its geographical situation closer to the sea, Boom clay at Essen presents a pore water salinity 4-5 times higher than Boom clay at Mol. This study aims at studying the effects of pore water salinity on the ...
متن کاملHydrogeological modeling of radionuclide transport in low permeability media: a comparison between Boom Clay and Ypresian Clay
Safe disposal of nuclear waste is an important environmental challenge. Several countries are investigating deep geological disposal as a long-term solution for their high-level waste. In Belgium, the Oligocene Boom Clay is the reference host formation for research purposes and for the safety and feasibility assessment of the deep disposal of high-level and/or long-lived radioactive waste. The ...
متن کاملControlled experiments
Controlled experiments, an approach that has been adopted from research methods in Psychology, feature large in the arsenal of HCI research methods. Controlled experiments are a widely used approach to evaluating interfaces (e.g. McGuffin and Balakrishnan, 2005) and styles of interaction (e.g. Moyles and Cockburn, 2005), and to understanding cognition in the context of interactions with systems...
