基于UO2-Zr弥散燃料板的结构与材料特性,利用已有的扩散、Nb-Zr反应以及UO2-Zr等材料学相关文献研究了UO2-Zr弥散燃料板严重事故过程中的氧化、固相反应以及熔融物迁移等特殊过程的机理模型,能为含UO2-Zr弥散燃料板堆芯的严重事故行为特性研究与安全分析提供参考。
Based on the structure and material properties of UO2-Zr dispersed fuel plates, the existing literature on diffusion, Nb-Zr reaction and UO2-Zr materials are used to study the oxidation and solid phase reactions of UO2-Zr dispersed fuel plates in severe accidents As well as the mechanism model of the special process such as the migration of the melt can provide a reference for the research and the safety analysis of the serious accident behaviors of the UO2-Zr dispersed fuel plate core.
