PhD in Natural Science Discipline

Uppsala University, Department of Physics and Astronomy/nThe research within the division of Materials Physics is centred around understanding the physical properties of materials by analysing their structure and composition across multiple length scales, from the atomic to the macroscopic, and linking them to functional properties. Core areas are magnetism, hydrogen, energy materials, soft matter and ion-solid interactions./nProject description: This PhD project aims to investigate how volatile fission products — such as xenon, krypton, iodine, and caesium — concentrate, diffuse, and redistribute within various types of nuclear fuel under different thermal conditions. The core experimental approach will involve ion implantation of these volatile elements into unirradiated nuclear fuel samples, followed by elemental depth profiling using ion-beam based measurement techniques, and subsequent thermal annealing experiments. The project will be carried out in close collaboration with experts from two Swedish universities and three major companies in the Swedish nuclear industry./nPlacement: Uppsala.
