摘要

The development and its corresponding technical features of spent nuclear fuel reprocessing were reviewed systematically according to the changes of its applications to different spent fuels and separation improvements. Aiming at the partition and transmutation (P&T) technologies in future advanced nuclear energy system, the improvements of the Purex process from Generation II reprocessing to Generations III and IV reprocessing were highlighted. The key radiochemical issues which should pay much attention in the Purex process and following partition processes as well as the dry reprocessing for spent nuclear fuel of fast reactors were summarized.
