This article studied the properties of two compositions of cermet fuels, U-15wt%UO2 and U-30wt%UO2. The thermal conductivity of the sintered cermets was determined by the transient plane source (TPS) technique using a Thermal Constant Analyzer. It was found that the thermal conductivity increased for both of the cermet compositions with increasing temperature. This was considered to be favorable as higher thermal conductivities ...
