📢 Numerical Modeling of THMC Couplings in Host Rocks for Radioactive Waste Disposal

Institution: ASNR (with collaboration from GeoRessources, Université de Lorraine) work in Paris region
Project Context: EURAD-2 (2024–2028) – European Joint Programme on Radioactive Waste Management
Research Area: Multiphysics modeling, porous media, THMC processes, upscaling, SPH, LBM

ASNR (in collaboration with GeoRessources, Univ. of Lorraine) is seeking a researcher (PhD level) to model coupled THMC processes in the Callovo-Oxfordian argillite, France’s proposed host rock for radioactive waste disposal (Cigéo project). The work focuses on gas migration, mechanical deformation, and phase changes at micro/meso scales, using DNS tools (SPH & LBM), GPU computing, and 3D imaging data. Objectives include upscaling pore-scale simulations to the continuum, improving physical couplings (thermal, multiphase, reactive), and benchmarking with simplified models and surrogate approaches (e.g., PINNs).

A call for applications for 10 Doctoral Programs has been announced by the Scuola Superiore Meridionale (SSM) in Naples (Italy). Specifically, the MERC program (Modeling and Engineering Risk and Complexity) emphasises an interdisciplinary approach to studying and managing complex systems, designing and engineering resilient systems, and analysing and managing risks and cascading effects. Within this context, geotechnical methods can be utilised to address hazard assessments related to landslides, seismic site responses, and other issues. Detailed hazard assessments can be further integrated into risk analyses for structures and lifelines to evaluate both their serviceability and ultimate state. This can also lead to the development of risk mitigation strategies through a decision support system.

We are looking for a PhD candidate fascinated by the response of quick clays that can change from solid to liquid with small environmental perturbations. The aim is to unravel the mechanisms, and time scales involved at particle scale, for the formation and failure of quick clays. A novel combination of miniaturised thermal-hydro-mechanical experiments and particle level modelling will be pursued to unravel the unique mechanisms that make quick clays so hazardous and at the same time so special. The originality of the experiments is in the combination of X-ray based scattering and imaging methods to monitor the changes at the particle scale during testing.

We are looking for a PhD candidate fascinated in modelling erosion processes in sensitive clay slopes. The highly sensitive clays, called quick clays, can change from solid to liquid with small environmental perturbations. We want to be able to understand how a changing environment will accelerate toe erosion thus affecting the stability of sensitive clay slopes, probably triggering catastrophic failures. We offer access to unique experimental data and computational tools developed by our research team for addressing a timely societally relevant problem.
