Purex流程中铀、钚含量及价态变化直接影响着后处理工艺的正常运行,铀、钚含量及价态变化需要实时监控。本工作的目的是研究和建立铀钚含量和价态的远距离快速分析装置,为后续分析方法的建立提供仪器保障。本装置(图1)由光源、光谱仪、光纤多路复用器、光纤、样品室、仪器控制等部件组成。光 Purex process uranium, plutonium content and valence changes directly affect the normal operation of the aftertreatment process, uranium, plutonium content and valence changes need real-time monitoring. The purpose of this work is to research and establish a long-range rapid analysis device for uranium-plutonium content and valence state, and provide instrumental support for the establishment of subsequent analytical methods. The device (Figure 1) by the light source, spectrometer, optical multiplexer, optical fiber, sample room, instrument control and other components. Light
