“…The calculation according to eq 1 (using interval estimation) gives 172.50 and 138 J mol −1 K −1 for the molar heat capacities of tetra-and trihalides, respectively. The experimental values 21,22 for thorium, plutonium, and uranium halides and their deviation from the calculated values are given in Table 3. The differences are within the experimental error.…”

The heat capacities of molten salts are very important for their practical use. Experimental investigation of this property is challenging because of the high temperatures involved and the corrosive nature of these materials. It is preferable to combine experimental investigations with empirical relationships, which allows for the evaluation of the heat capacity of molten salt mixtures. The isobaric molar heat capacities of all molten alkali and alkaline-earth halides were found to be constant for each group of salts. The value depends on the number of atoms in the salt, and the molar heat capacity per atom is constant for all molten halide salts with the exception of the lithium halides. The molar heat capacities of molten halides do not change when the anions are changed.

“…This work presents new measurements for PuF 3 and for the mixture LiF-ThF 4 -UF 4 -PuF 3 (77.5e6.6-12.3e3.6 mol%), selected as a possible fuel composition for the MSFR. Because no experimental data was available in literature for this mixture, results were discussed comparing calculated values obtained using the thermodynamic database assessed by Capelli et al [36]. In general, calculations predicted quite well experimental values, but some significant deviations (e.g.…”

“…Given uncertainties are based on the experience and the literature [35], which suggests to use a larger error for the liquidus point as the signal is less clear. Both transitions were calculated using the thermodynamic database assessed by Capelli et al [36] in combination with the FactSage thermodynamic software [37]. A visual representation of the calculations is given in Fig.…”
