发展核电是实现国家“双碳”目标、推动产业结构转型升级的重要途径。核能资源开采、利用和后处理产生核废物,由于其半衰期长,对环境造成潜在危害,因此构建多重屏障以安全有效地处置核废物是避免环境风险的重要措施。固化预处理是核废物处置的首要屏障。人造矿石固化核废物因具有耐辐照、高稳定性、低增容比的特点,被认为是构建核废物固化首要屏障的理想方法。综合论述了人造矿石固化核废物的研究进展,系统阐述了人造矿石固化放射性核素的方法和矿石类型,并结合人造矿石形成的结构和理化特征,阐明人造矿石固化放射性核素的机制,提出了适合不同放射性核素固化的人造矿石类型和方法。同时,分析了固化放射性核素辐照对人造矿石晶相结构特征和稳定性的影响,为人造矿石固化放射性核素的策略提供了重要的科学支撑,为实际应用奠定了重要的理论基础。

Development of nuclear power is an important means to implement the national strategicgoals of achieving " carbon peak" and " carbon neutral" , promoting the transformation and upgrading ofthe industrial structure. Nuclear waste is generated during the exploitation, utilization, and disposal ofnuclear energy resources. Due to its long half-life, nuclear waste poses long-term environmental haz⁃ards. Constructing multiple barriers is a safe and effective measure for the disposal of nuclear waste,mitigating the environmental risks it poses. Solidification pretreatment serves as the first barrier for nu⁃clear waste disposal. The solidification of nuclear waste by synroc is considered to be an ideal methodfor creating the first line of defense due to its characteristics of radiation resistance, high stability, andlow capacity ratio. This work provides a comprehensive review of the research advances in the solidifica⁃tion of nuclear waste using synroc. It discusses the methods and types of synroc employed for the solidi⁃fication of nuclear waste. The mechanism of the solidification of nuclear waste using synroc isunderstood through the analysis of microstructure and physicochemical characteristics. Suitablestrategies and types of synroc for the solidification of nuclear waste are proposed. Additionally, theeffects of radionuclide irradiation on the crystal structure and stability of synroc are analyzed. These re⁃sults provide an important reference for the application of synroc solidification of nuclear waste.
