摘    要:长寿命裂变产物的分离不仅可有效提高乏燃料后处理与高放废物处置安全性,而且可降低高放废物对人类和环境的危害.鉴于用于分离长寿命裂变产物的萃取剂在分离过程中通常处在较高的辐射场中,因此为了设计合适的萃取分离体系,有必要开展对裂变产物具有良好萃取性能的萃取剂的辐射稳定性的研究.本文通过对比辐照前后萃取剂的化学结构和萃取性能的...

Abstract:The separation of the long-lived fission products from dissolved nuclear fuel could improve the safe disposal of high-level nuclear wastes and reduce their threaten to human being and environment. Since the extractant system will be exposed to high radiation environment during the solvent extraction of long-lived fission products. The understanding of radiation chemistry of extractants is very important for practical design of extractant system. The radiation chemistry of crown ether systems proposed for use in the solvent extraction of one of fission products 90Sr were reviewed based on the study on the radiation stability and radiolysis mechanism of crown ether system. Finally some challenges were suggested.
Keywords:90Sr  extractants  radiation chemistry  progress
