XAFS-XRD simultaneous measurement system to observe the reactions of nuclear fuel under ultra-high temperatures was developed. In this presentation, we will introduce the overview and performance of the measurement system installed at JAEA beamline BL22XU of SPring-8. We will also report the results of the simultaneous measurement of Zr and Y-K edge XAFS spectra and X-ray diffraction pattern of Zr-Y₂O₃ mixture under ultra-high temperature by using the heating equipment reported in series presentation (2).
