Abstract Scope |
Iron-chromium-aluminum (FeCrAl) alloys, APMT and C26M, are being investigated for their use as accident-tolerant fuel (ATF) cladding materials to potentially replace conventional zirconium alloy cladding. FeCrAl alloys offer improved corrosion resistance, particularly in the event of an incident scenario. At high temperatures, the FeCrAl alloys demonstrate the formation of a protective layer of aluminum oxide (Al2O3) on the outer surface, further enhancing their corrosion resistance. This study simulates accident scenario conditions by subjecting the FeCrAl alloys to rapid induction heating up to 800°C, 1000°C, and 1200°C for a set time, followed by water quenching the samples. Tests were performed for each alloy in two environments: dry air and generated steam. The surface chemistry and microstructure of the FeCrAl alloys under these conditions were evaluated using advanced materials characterization techniques to elucidate their response under the evaluated conditions. |
