We have developed a scanning transmission x-ray microscope system in order to analyze the chemical spiecies and the redox states in nuclear fuel materials after ultra-high temperature heating with a spatial resolution of several tens of nm. We will present the results of comissioning of the system and its application to the analysis of the oxygen chemical state in the simulated fuel material Zr-Y₂O₃.
