Analytical Methods of Dry Reprocessing Technology for Spent Nuclear Fuel

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.
