摘要：

The heat capacities of UPd3 and U(Pd0.85Rh0.15)(3) were measured over the temperature range between 290 and 1500 K by direct heating pulse calorimetry, which is a direct method for heat capacity measurements. The measured heat capacities of UPd3 were smaller than the literature values up to 900 K. The heat capacities of U(Pd0.85Rh0.15)(3), obtained for the first time, were a little larger than those of UPd3, but showed a similar temperature dependence. Since the oxygen partial pressures for the oxidation of UPd3 and U(Pd0.85Rh0.15)(3) alloys were calculated from the heat capacities to be higher than that for MoO2(s), UPd3 and U(Pd0.85Rh0.15)(3) are not expected to be oxidized during the irradiation of UO2 fuel.
