乏燃料干法后处理研究中的分析方法

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 ,UV‐Vis 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 .
