FeCrAl-ODS steel is one of candidates for Accident Tolerant Fuel (ATF) cladding material. To investigate the detail oxidation behavior of the material, the authors conducted oxidation tests in high temperature steam flow in thermobalance chamber. After the tests, surface oxide layer was studied by using laser Raman spectroscopy, scanning electron microscopy and electron dispersed X-ray spectroscopy to discuss the difference of oxidation behavior at different testing temperature. At 1150 C, the surface oxide layer was Alumina, and at 750 C, it was Fe oxides. The detail of our investigation will be discussed in the session.
