Uranium-plutonium-zirconium (U-Pu-Zr) alloys are considered to be leading metallic fuel candidates for fast reactor and transmutation fuel applications. This contribution reports the results of transmission electron microscopy investigation of the microstructure and phases formed in the U-Pu-Zr systems since the complete understanding of the irradiation behavior of U-Pu-Zr transmutation fuels cannot be achieved without this fundamental knowledge. This report utilizes several characterization techniques in identification of fuel microstructure, including but not limited to energy and wavelength dispersive spectroscopy (EDS/WDS), scanning and transmission electron microscopy (SEM/TEM), and selective area electron diffraction (SAED) analysis. The high spatial resolution of TEM allowed characterization of individual matrix phases. Selected-area electron diffraction (SAED) analysis provided important space-group information and lattice parameters of the phases formed in ternary U-Pu-Zr system.
