Heat Capacity Measurements

Heat capacity measurements have been performed on solid CH3D over the range 0.15 < T < 4 K where a large Schottky anomaly occurs. The entropy change in the anomaly is estimated to be 1.80 ± 0.10R which is about 14% less than that corresponding to complete orientational ordering of the molecules and total conversion of nuclear spin symmetry species. Some time effects associated with thermal equilibration have also been studied.

Thermal Conductivities

AbstractThermal conductivities of Cs-M-O (M= Mo or U) ternary compounds, observed in the pellet-cladding gap region and in the pellet periphery in irradiated oxide fuels with high oxygen potentials, were investigated. Bulk samples of Cs2MoO4and Cs2UO4were prepared by hot pressing or spark plasma sintering, and their thermal diffusivities were measured by the laser flash method from room temperature to 823 K for Cs2MoO4and to 900 K for Cs2UO4. The thermal conductivities were evaluated from the thermal diffusivity and bulk density, and the specific heat capacity values available in the literature. The thermal conductivities of Cs2MoO4and Cs2UO4were quite low compared with UO2(e.g. 0.5 Wm−1K−1at 800 K for Cs2MoO4).
