High temperature measurements

High temperature measurements and condensed matter analysis of the thermo-physical properties of ThO$_2$

Values are presented for thermal conductivity, specific heat, spectral and total hemispherical emissivity of ThO$_2$ (a potential nuclear fuel material) in a temperature range representative of a nuclear accident - 2000 K to 3050 K. For the first …

Measurement and interpretation of the thermo-physical properties of UO$_2$ at high temperatures: The viral effect of oxygen defects

Values are reported of specific heat, thermal conductivity and thermal diffusivity of UO2from 1500 K to 2900 K based on laser flash measurements. Experiment is complemented by the development of solid state physics models that aid in the …
