We have developed an apparatus for in-situ observation of transmission XAFS spectra and X-ray diffraction patterns at very high temperatures, and have successfully measured samples of the UO₂-ZrO₂ system under sealed conditions. We report on the outline of the apparatus and the obtained spectral data.
