Subject: "Multi-scale modeling of UO2 plasticity: on the role of irradiation defects"

Description: The main goal of the PhD is to develop a constitutive model based on dislocation interactions with irradiation loops. This model is needed to compute inelastic strains induced at high temperature and under irradiation. First, dislocation mobility and reactions between defects will be characterized using the atomic scale LAMMPS molecular dynamics (MD) package. Then, atomistically-informed dislocation dynamics (DD) simulations will be performed at the grain scale to quantify strain hardening induced by irradiation defects.

The Ph.D will be done in the framework of a collaboration between INSA-Lyon (jonathan.amodeo@insa-lyon.fr), the University of Lyon (david.rodney@univ-lyon1.fr) and the CEA at Cadarache (bruno.michel@cea.fr, emeric.BOURASSEAU@cea.fr).

Application: CV and application letters should be sent to david.rodney@univ-lyon1.fr, jonathan.amodeo@insa-lyon.fr, bruno.michel@cea.fr.
