The precise determination of critical elements such as uranium and plutonium in spent nuclear fuel reprocessing workflows holds paramount significance for process optimization and safety assurance. Building upon international technological precedents, the LiF(200) doubly curved crystal optical element was optimized and selected, and the MWDXRF prototype for quantitative analysis of actinide elements was successfully developed. The results of the diffraction intensity and fluorescence characteristic experiments show that the instrument is feasible for the micro-trace-level analysis of actinide elements, and its detection limit for uranium determination is 18.97 μg/mL. The development of the device provides a new way for novel approaches to the simultaneous determination of trace/ultra-trace actinides in complex matrices.

乏燃料后处理工艺流程中,精确测定铀、钚等关键元素含量对于流程优化及安全保障具有至关重要的意义。在借鉴国外技术基础上,优化筛选出LiF(200)双曲面弯晶光学元件,成功研制出用于锕系元素定量分析的MWDXRF原型机。衍射强度和荧光特性试验研究结果表明,该原型机可用于锕系元素微痕量分析,其对铀的测定检出限为18.97 μg/mL。该设备的研发为后续复杂体系中微痕量锕系元素的共测技术提供了一种新的路径。

乏燃料后处理工艺流程中,精确测定铀、钚等关键元素含量对于流程优化及安全保障具有至关重要的意义。在借鉴国外技术基础上,优化筛选出LiF(200)双曲面弯晶光学元件,成功研制出用于锕系元素定量分析的MWDXRF原型机。衍射强度和荧光特性试验研究结果表明,该原型机可用于锕系元素微痕量分析,其对铀的测定检出限为18.97 μg/mL。该设备的研发为后续复杂体系中微痕量锕系元素的共测技术提供了一种新的路径。

The precise determination of critical elements such as uranium and plutonium in spent nuclear fuel reprocessing workflows holds paramount significance for process optimization and safety assurance. Building upon international technological precedents, the LiF(200) doubly curved crystal optical element was optimized and selected, and the MWDXRF prototype for quantitative analysis of actinide elements was successfully developed. The results of the diffraction intensity and fluorescence characteristic experiments show that the instrument is feasible for the micro-trace-level analysis of actinide elements, and its detection limit for uranium determination is 18.97 μg/mL. The development of the device provides a new way for novel approaches to the simultaneous determination of trace/ultra-trace actinides in complex matrices.
