摘要：

We characterized the lattice parameter and phase transformation behaviors of six uranium-based metallic fuels in the temperature range 303-1173 K using in situ high-temperature X-ray diffraction (HT-XRD). In all of the fuels, alpha-U crystal structure almost vanished at 1023 K while UO2 crystal structure started forming at 843 K. Fawley refinement of HT-XRD data revealed anisotropic lattice thermal expansion with increases along the a- and c-axes upon annealing in all the metallic fuels. Furthermore, we confirmed that rare-earth elements (Nd, Ce, Pr, and La) contained in the U-10Zr metallic fuel hardly influenced the thermal behavior of the lattice parameters. (C) 2019 Elsevier B.V.
