摘　　要：放射性废树脂处理是放射性废物管理的重要挑战之一,目前尚缺乏有效解决方案。传统方法如直接水泥固化、热态超级压缩、焚烧等,存在明显的局限性。超临界水氧化技术因其对有机物处理迅速彻底且能高效减容而备受关注。首先,从超临界水的基本特性出发,综述了温度、压力、氧化系数、停留时间及物料浓度等反应条件对放射性废树脂有机物去除效率影响的研究进展;其次,分析了超临界水氧化技术的优缺点;最后,从实际应用的角度,展望了超临界水氧化技术在处理放射性废树脂过程中仍面临的问题,以期为超临界水氧化处理放射性废物的工业应用提供参考和指导。Radioactive waste resin treatment is a key challenge in radioactive waste management,which still lacks effective solutions.Traditional methods such as cement solidification,hot super-compaction,and incineration exhibit significant limitations.Supercritical water oxidation(SCWO)is noteworthy for its swift organic treatment and volume reduction.This review states the fundamental characteristics of supercritical water and provides a comprehensive overview of the research progress on reaction conditions such as temperature,pressure,oxidant coefficient,residence time,and material concentration on the removal efficiency of organic compounds from radioactive waste resins.Additionally,the advantages and disadvantages of this technology are analyzed.Finally,from a practical application perspective,challenges that SCWO technology still faces in the treatment of radioactive waste resins are discussed,which can provide references and guidance for the industrial application of SCWO in treating radioactive wastes.
