Consequences of the Thermal Transient on the Evolution of the Damaged Zone Around a Repository for Heat-Emitting High-Level Radioactive Waste in a Clay Formation: a Performance Assessment Perspective

Vincent Labiouse, Xing Li

A proper evaluation of the perturbations of the host rock induced by the excavation and the emplacement of exothermic wastes is essential for the assessment of the long-term safety of high-level radioactive waste disposals in clay formations. The impact of ...

On the Fluid Retention Properties of Shales

Lyesse Laloui, Alessio Ferrari, Valentina Favero

The development of engineering activities involving shales such as the extraction of shale gas and shale oil, the nuclear waste geological storage and the sequestration of CO2, has led to an increasing interest toward the geomechanical behaviour of this ge ...

On the water retention behaviour of shales

Lyesse Laloui, Alessio Ferrari, Valentina Favero

Shales are among the most considered geomaterials in current energy-related geomechanical investigations; they are involved in engineering applications such as the unconventional extraction of natural gas, CO2 sequestration and nuclear waste geological sto ...

Trace concentration - Huge impact: Nitrate in the calcite/Eu(III) system

Kislon Voitchovsky

The interactions of trivalent lanthanides and actinides with secondary mineral phases such as calcite is of high importance for the safety assessment of deep geological repositories for high level nuclear waste (HLW). Due to similar ionic radii, calcium-be ...

Pore structure evolution of compacted granular bentonite during wetting and drying cycles

Lyesse Laloui, Alessio Ferrari, Ali Seiphoori

Deep geological repositories are considered as suitable solutions for the disposal of high level nuclear wastes. In several repository concepts (e.g. in Spain and Switzerland), bentonites are selected as the main component of the engineered barrier to be p ...

Experimental analysis of the water retention behaviour of shales

Lyesse Laloui, Alessio Ferrari, Valentina Favero

Shales are among the most commonly considered geomaterials in current energy-related geomechanical investigations, as they are involved in engineering applications such as the unconventional extraction of natural gas, CO2 sequestration and nuclear waste ge ...

The Pore Structure Of Compacted And Partly Saturated Mx-80 Bentonite At Different Dry Densities

Alessio Ferrari, Ali Seiphoori

Compacted MX-80 bentonite is a potential backfill material in radioactive-waste repositories. Pore space in MX-80 has been the subject of considerable debate. 3D reconstructions of the pore space based on tomographic methods could provide new insights into ...

An Insight into the Fluid Retention Capabilities of Shales

Lyesse Laloui, Alessio Ferrari, Valentina Favero

The hydro-mechanical behaviour of shales is becoming one of the most important issues in modern geomechanics, largely driven by petroleum industries (i.e., the extraction of shale gas), the sequestration of CO2 and the nuclear waste geological storage. In ...

THM coupling sensitivity analysis in geological nuclear waste storage

Lyesse Laloui, Fabrice Dupray, Chao Li

A deep geological repository involving a multi-barrier system constitutes one of the most promising options to isolate high-level radioactive waste from the human environment. In order to certify the efficiency of waste isolation, it is essential to unders ...

Thermo-Hydro-Mechanical Modelling of Hollow Cylinder Laboratory Experiments on Boom Clay

Vincent Labiouse, Bertrand François

The aim of the TIMODAZ project is to investigate the effect of thermal changes on the excavation damaged zone (EDZ) around nuclear deep disposals in clay-based geological formations. In the framework of WP5.2 of this project, it is intended to develop cons ...
