Abstract
The thermal diffusivity of the ThO2-UO2 system in solid solution was measured by laser pulse method at temperatures ranging from 20° to 500°C. Reproducibility of the data was confirmed to be within 3%. The compositions of the samples were ThO2, ThO2-1%UO2, ThO2-5%UO2 and ThO2-10%UO2. The thermal conductivity was calculated from measured thermal diffusivity data and the specific heat data available in literature and corrected to zero porosity by using Loeb's equation, in which the shape factor is unity. The values on ThO2 thus obtained agreed very well with the data found in literature, throughout the range of temperature of the experiments. The thermal conductivity of ThO2, ThO2-1%UO2, ThO2-5%UO2 and ThO2-10%UO2, at 20°C, were 0.0312, 0.0288, 0.247 and 0.0184 cal·cm/sec· °C·cm2, respectively.Keywords
