Abstract Scope |
Uranium trichloride, UCl3, 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 e.g. the thermal expansion of the hexagonal a and c lattice parameters. The results are compared to DFT calculations. The melting point of UCl3 is determined by differential scanning calorimetry to be 1108.2K. |
