High-temperature oxidation behavior and degradation mechanism of chromium-coated zirconium alloy cladding: a review
摘要
Accident-tolerant fuels (ATF) have been extensively studied to reduce the production rate and total amount of heat and hydrogen generated from high-temperature steam oxidation during severe accidents. Chromium-coated zirconium alloy cladding has become one of the most promising candidates for ATF because of its excellent corrosion and oxidation resistance. This paper provides a comprehensive overview of the research progress on oxidation behaviors and degradation mechanisms in chromium-coated zirconium alloy cladding under high-temperature conditions. Potential techniques to strengthen the oxidation resistance are highlighted and compared. Finally, challenges and opportunities for various future directions are addressed.
