Abstract Scope |
FeCrAl alloy systems are emerging as promising candidates to replace Zr-based nuclear fuel cladding materials due to their corrosion resistance in Loss of Coolant Action (LOCA) like scenarios. However, there is limited understanding of the elemental effects on the oxidation resistance of alloys in Boiling Water Reactor (BWR) conditions. Understanding the role of elements on the degradation mechanisms in both BWR and LOCA conditions is essential for developing next-generation Multiple Principal Component Alloys (MPCA). This work systematically explores the corrosion resistance of two FeCrAl alloys; Fe-21Cr and Fe-21Cr-5.5Al in the steam environment at 400 °C and 1200 °C. The samples were characterized upon exposure to identify the corrosion products and understand the corrosion mechanism under varying parameters. The results enhanced the understanding of the role of Al in affecting the corrosion resistance at both temperatures and provided implications for developing next-generation FeCrAl-based MPCA Fuel Claddings. |
