Short-term oxidation behavior of Cr-coated Zr-1Nb in severe accident environments: steam and air

Abstract This study examines Cr-coated Zr-1Nb alloy cladding oxidation in steam/air (600–1200 °C), simulating accident scenarios. Thermogravimetry and static air tests revealed Cr coatings form granular oxides in air and coral/worm-like structures in steam (H2 release-driven). Cr3+ migration governs...
