摘要
放射性尾气中碘的净化处理在核能安全利用、环境保护以及核燃料后处理工艺过程中起到至关重要的作用.文中分析了放射性碘在核电站、乏燃料后处理工艺过程中的走向,总结了国内外核设施尾气中放射性碘的净化处理现状,阐述并总结了气体中放射性碘净化处理的各种方法及其原理、优缺点,着重分析了近年来热点研究的MOFs和POPs多孔材料对气体中放射性碘的捕集情况.通过对比不同的气体中放射性碘净化处理技术和不同的吸附剂,对气体中放射性碘净化处理的发展方向、新型MOFs和POPs多孔材料的研究以及我国乏燃料后处理厂碘的处理工艺提出了建议.
Iodine removal from radioactive off-gases plays an important role in the safe use of nuclear energy,environmental protection and nuclear fuel reprocessing.This paper analyzes the trend of radioactive iodine in nuclear power plants and the treatment process of spent fuel reprocessing,and summarizes the present situation of radioactive iodine removal from the off-gases of nuclear facilities at home and abroad.It then expounds and summarizes the principles,advantages and disadvantages of various methods of radioactive iodine removal from gases,with a focus on the analysis of the capture of radioactive iodine in gases by MOFs and POPs porous materials,which have been popular research topics in recent years.By comparing different technologies and different adsorbents of radioactive iodine removal from gases,this research puts forward suggestions for the development direction of radioactive iodine removal from gases,the research of new MOFs and POPs porous materials,and the treatment process of iodine in spent fuel reprocessing plants in China.
