Imaging XAFS technique using X-ray CCD camera has a remarkable feature of position sensitivity in contrast with the standard XAFS technique using ionic chambers. We have obtained XAFS spectra of nuclear materials at the BL-27B station located in the KEK and maintained by JAEA. In the present work, imaging XAFS measurement of actinide oxides was performed to confirm that it can be useful in researches on nuclear fuel and reprocessing of spent fuels in the future.
