Abstract: As one of the core technologies within used nuclear fuel reprocessing, the research and application status of analytical techniques reflects the analytical capability. This paper aims to present an overview of this status in China. In terms of analysis in aqueous reprocessing, first, the research and application of analytical methods were summarized; Then, the development and application of specialized analytical devices, automatic analytical devices, and online analytical devices were outlined. Meanwhile, the development of analytical reference materials in reprocessing was described. In terms of analysis in dry reprocessing, since the state and components of analytical samples are significantly different from those in aqueous reprocessing, specialized development of analytical techniques is required. Thus, the research progress of analytical techniques in dry reprocessing was elaborated. Finally, future improvements and research directions for analytical techniques in used nuclear fuel recycling processes in China were proposed.
