摘　　要：放射性污染不锈钢废液贮罐的去污,往往是不锈钢贮罐退役拆除的先决条件。放射性污染贮罐内由于其结构以及长期储存放射性废液,往往可达性不佳。因此具有流动性,且可以远程操作的化学试剂去污工艺是一种很好的选择。本文简要梳理了强酸、弱酸和强酸盐、氧化剂和还原剂以及有机酸等放射性不锈钢废液贮罐常用的去污试剂类型,并介绍了当前国内外不锈钢贮罐的化学去污技术。基于当前现状,结合我国实际情况,提出了当前化学去污试剂的发展方向应关注试剂去污时的贮罐安全性,和后续二次废物处理方面的问题。The decontamination of radioactive stainless steel storage tanks is often a prerequisite of decommissioning and dismantling.This article briefly summarizes the commonly used types of decontamination reagents for radioactive stainless steel storage tanks,such as strong acids,weak acids and strong acid salts,oxidants and reducing agents,and organic acids.It also introduces the current chemical decontamination technologies for stainless steel storage tanks at home and abroad.Based on the current situation and combined with the actual situation in China,it is proposed that the development direction of chemical decontamination reagents should pay attention to the safety of reagent decontamination and the issues related to subsequent secondary waste treatment.
