以磷酸三丁酯(TBP)为萃取剂的Purex流程是目前世界上唯一实现工业化应用的乏燃料后处理水法流程。乏燃料后处理工艺操作是在很强的α、β和γ辐射场下进行的,α、β和γ射线均可引发辐解效应。当受到热、酸或离子辐射作用时,TBP降解生成的主要产物是磷酸二丁酯(DBP)和少 The Purex process with tributylphosphate (TBP) as the extractant is the only spent fuel reprocessing water process in the world that is the only industrialized application. Spent fuel reprocessing operations are performed under strong α, β and γ radiation fields, and α, β and γ-rays can initiate radiolysis. When subjected to heat, acid or ionizing radiation, the major products of TBP degradation are dibutyl phosphate (DBP) and less
