Abstract—

The use of magnetic fields in nonaqueous spent nuclear fuel treatment processes involving molten salts opens up new possibilities for selective extraction of radionuclides. In this research, this approach has been applied to the selective extraction of rare-earth elements and zirconium. We have studied strontium hexaferrite and a spinel ferrite as a magnetic carrier, examined the feasibility of utilizing it alkali chloride melts, and analyzed the effect of process conditions (temperature, holding time, and Zr content) on the effectiveness of Nd and Zr extraction by magnetic separation.

磁选法从熔融盐中分离稀土元素和锆

摘要-

在涉及熔融盐的非水乏核燃料处理过程中使用磁场为选择性提取放射性核素开辟了新的可能性。在这项研究中，该方法已应用于选择性提取稀土元素和锆。我们研究了六锶铁氧体和尖晶石铁氧体作为磁性载体，研究了将其用于碱式氯化物熔体的可行性，并分析了工艺条件（温度，保持时间和Zr含量）对Nd和Zr萃取效率的影响。磁选。
