Abstract
The thermal diffusivities of (U1−yCey)O2 were measured from room temperature to 1673 K using laser flash method, and the lattice parameter was examined as a function of Ce contents using X-ray diffractometry to investigate the theoretical density of each composition. The thermal conductivities normalized to 95% of theoretical density decreased with increasing Ce contents. From the fitting results, it was shown that the increasing CeO2 content as a solid solution affected the lattice contribution and that the effect of the electron contribution was added at higher Ce content.
