次锕系元素是乏燃料后处理产生的高放废液(HLLW)中对人类环境具有长期潜在放射性危害的决定核素。将它们从HLLW中分离并进行嬗变处理是根本解决途径。20世纪80年代欧、美等提出了分离/嬗变策略,该策略旨在将长寿命核素嬗变处理成短寿命核素,降低其对环境的放射性威胁。该技术提出至今已获得多方面的技术突破,但目前研究的重点及难点在于化学分离部
Minor actinides are deterministic nuclides of long-term potential radioactive hazards to the human environment in high-level liquid waste (HLLW) from spent fuel reprocessing. Separating and transmutating them from HLLW is the fundamental solution. In the 1980s, Europe and the United States proposed a separation / transmutation strategy aimed at transmuting long-lived nuclides into short-lived nuclides and reducing their radiological threats to the environment. The technology proposed so far has been a wide range of technological breakthroughs, but the focus of the current study and the difficulty lies in the Department of Chemical Separation
