📢 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).
