Job Description
Thesis Subject
This thesis will study the properties of chromium-doped UO2 pellets for the retention of a gaseous fission product (Xe) under irradiation. These pellets represent a new generation nuclear fuel concept called ATF (Accident Tolerant Fuel), designed to be a more effective containment barrier than current UO2 fuel in accident conditions. The thesis aims to determine the migration mechanisms of xenon under irradiation, correlated with changes in the structural and physicochemical properties of the material under study. Xe will be introduced by ion implantation, and the samples will be subjected to irradiation treatments on accelerators, favoring either electronic effects (irradiation with high-energy ions) or ballistic effects (low-energy ions). The evolution of Xe (diffusion, release, bubble formation) and the material will be characterized by combining different techniques: concentration profile analysis by Secondary Ion Mass Spectrometry (SIMS), transmission electron microscopy (TEM), Raman spectroscopy, and X-ray absorption spectroscopy. This thesis is part of the European FIGARO project, funded by the CONNECT-NM program.
The student must have a strong background in chemistry, physical chemistry, or materials science. A good level of French and English is essential.
Your Work Environment
The candidate will work in the MATiCE (Materials in Extreme Conditions) group at the Institute of Physics of the Two Infinities of Lyon (IP2I), a laboratory affiliated with the IN2P3 Institute of CNRS and Lyon 1 University. The MATiCE team's research focuses on the evolution of the physicochemical and structural properties of materials used in the nuclear industry under extreme conditions, particularly temperature and irradiation. The studies also deal with the diffusive behavior of certain elements simulating fission products (FPs) and activation products within these materials.
Constraints and risks
The candidate must be able to work with ionizing radiation.
