摘　　要：综述了几种典型的乏燃料干法后处理方法,并对其中使用的分析方法进行了总结。详细论述了干法后处理研究中的在线分析方法,包括电化学分析方法、紫外可见吸收光谱法、X射线衍射法、拉曼原位分析、EXAFS原位分析、NMR原位分析等。在线分析方法有助于对工艺料液中物质的形态及结构进行实时监测。此外,离线分析方法可作为在线方法的有效补充,根据研究对象的形态(气态、液态、固态)对一些典型的离线分析方法进行了论述。Some typical technical routes of dry reprocessing for spent nuclear fuel were reviewed and the analytical methods used in the processes were summarized.Several methods for on-line monitoring were demonstrated in detail,including electroanalytical methods,UVVis absorption spectrometry,X-ray diffraction analysis,in-situ Raman spectrometry,in-situ EXAFS analysis and in-situ NMR analysis.On-line analytical methods can give real-time information of the morphologies and structures.As the effective complementarity of on-line analytical methods,off-line analytical methods were discussed based on different states of the study object,such as the one in a gas,solid or liquid state.
