Abstract: New thermal diffusivity data for homogeneous SBR and heterogeneous MIMAS and OCOM MOX fuels are reported. No significant difference between the thermal diffusivity of the homogeneous and heterogeneous fuels was found at the burn-up of 44 MWd/kgHM. These measurements, combined with previously published results or correlation functions for irradiated UO2 and MOX were compared and it was found that separate correlations for these two fuels are not justified. A correlation for the thermal conductivity of irradiated UO2 and MOX as a function of burn-up and irradiation temperature is proposed.
