b'TALENT PIPELINE: This research demonstrated that the electron probe microanalyzer can be used to Karen Wright, student distinguish small changes in oxygen-to-metal stoichiometry. Therefore, it is possible at Technical University Delft to use electron probe microanalysis to measure non-stoichiometric uranium dioxide Mike Matthews, student and to use that data to determine diffusion coefficients for oxide species in oxide fuel. at the University of Bristol This should enable improved modeling capabilities for fission product transport in oxide fuels, thus improving predictions, particularly for off-normal events.PRESENTATIONS:Wright, K.
