Heat treatments of U - Zr - O mixtures of different oxygen contents (ranging from 1 to 35 at. %) and of a constant U/Zr ratio (U/Zr = 1.35 which is characteristic of the inner part of a pressurized-water reactor) were performed in order to study the high temperature behavior of corium. The selected U-Zr-O mixtures were put in a tungsten crucible and heated to 2050{degrees}C. The specimens were thereafter analyzed by Scanning Electron Microscopy (SEM), Electron Probe MicroAnalysis (EPMA) and Electron BackScattering Diffraction (EBSD).
