摘要
为了减少核电反应堆产生的乏燃料对环境的影响,国际上开展了分离/嬗变和先进核燃料循环的研究。其中,从核废物中分离回收次要锕系和长寿命裂变产物是关键步骤。乏燃料后处理和高放废液分离一体化流程与现有乏燃料处理处置方式相比,流程简单、二次废物少、经济性高,更能满足先进核燃料循环的分离要求。介绍了国内外在乏燃料后处理和高放废液分离一体化流程研究方面的成果和进展情况。
In order to minimize the environmental impact of nuclear spent fuel discharged from nuclear power reactors, researches of partitioning/transmutation and advanced nuclear fuel cycle are expanded in several nations. Separation of minor acitinides and long-lived fission products is the key process for such purpose. Compared to the current method for spent nuclear fuel treatment and disposal, the integrated process of reprocessing and high-level waste partitioning has distinct advantages, such as simplifying processing, reducing the secondary waste and improving economics. The integrated process is much more suitable for advanced nuclear fuel cycle. In this paper the recent advancement and progress on the integrated process of reprocessing and high-level waste partitioning are described.
