Abstract

Uranium trichloride (UCl<subscript>3</subscript>) is actively researched to develop and improve applications ranging from molten salt reactors to actinide processing, including spent fuel reprocessing. Here, we report for the first time the crystal structure evolution between room temperature and melting point from in situ high-temperature neutron diffraction to quantify, for example, the thermal expansion of the hexagonal a and c lattice parameters. The results are compared with density functional theory calculations. The melting point of UCl<subscript>3</subscript> is determined by differential scanning calorimetry to be 1108.2 ± 0.2 K.
