摘要
锆合金由于其良好的综合性能在压水反应堆燃料包壳领域得到广泛应用,在反应堆运行过程中,高温水腐蚀是导致锆合金包壳失效并决定燃料服役寿命的主要原因。一回路水环境作为锆合金包壳的服役环境,需要起到传递热能、抑制腐蚀产物沉积等作用,水化学的优化是提高反应堆经济性与安全性的重要措施之一。锆合金的耐腐蚀性能受到水化学环境显著影响,本文综述了几种水化学参数对锆合金耐腐蚀性能的影响研究进展,探讨了不同水化学参数对锆合金腐蚀的影响机理,为反应堆水化学改善以及锆合金腐蚀行为研究提供参考,并对未来反应堆水化学以及锆合金材料的研究方向作出展望。
Zirconium alloys are extensively utilized in reactor fuel cladding for their superior properties,including high corrosion resistance and low thermal neutron absorption cross-section and good mechanical properties.However,the main cause of failure in zirconium alloy cladding during reactor operation is its susceptibility to corrosion,a subject extensively researched.As the service environment of zirconium alloy,the water environment plays a role in inhibiting the corrosion of materials except the transfer of heat energy,and the optimization of water chemistry is one of the most important measures to improve the economy and safety of the reactor.This paper reviews the influence of water chemistry on the corrosion resistance of zirconium alloys,and discusses how different chemical parameters affect this process.It provides insights into how water chemistry affects zirconium alloy’s corrosion resistance,offers guidance on the future research directions of reactor water chemistry and zirconium alloy materials.
