# Thermal diffusivity measurements on UO$_2$ fuels with the flash method

* Corresponding author
Abstract : Thermal conductivity of the nuclear fuel : -A key parameter to understand the performance of the fuel under irradiation -Highly dependent on microstructure, porosity and its distribution -Influences almost all important processes such as fission gas release, swelling Knowledge of the nuclear fuel thermal conductivity (derived from a thermal diffusivity measurement): - A fundamental data for a better prediction of fuel performance in reactor - Must be measured accurately (including a reliable uncertainty assessment
