Abstract
We prepared polycrystalline pellets of (U,Y)O2, containing YO1.5 up to 11Â mol.%. We performed indentation tests on the pellets, and evaluated the Young's modulus and hardness. We measured the heat capacity and the thermal diffusivity, and evaluated the thermal conductivity. We succeeded in evaluating the effect of Y content on the thermophysical properties of (U,Y)O2. We revealed that the Young's modulus, hardness, and thermal conductivity of (U,Y)O2 decreased with increasing the Y content.
