摘　　要：核设施产生的废树脂的安全处理、整备和处置是热点问题。本文论述了废树脂的特殊性 ,解析了各种废树脂处理、整备技术 ,包括脱水干燥后装入高整体性容器、洗脱、热压、生物降解、焚烧、湿法氧化、沥青固化、聚合物固化、玻璃固化和水泥固化等。重点分析了废树脂水泥固化 ,讨论了树脂溶胀作用破坏固化体的机理 ,介绍了克服树脂溶胀作用的方法。强调指出必须重视水泥固化的配方 ,关键是必须满足处置要求。最后 。Safety treatment,conditioning and disposal of spent ion exchange resin (SR) from nuclear facilities is a hot topic.The SR features,various treatment and conditioning methods,such as filling into the high integrity container after drying and dewatering,elution,hot compaction,biodegradation,incineration,wet oxidation,bituminisation and vitrification are described in this paper.Especially,the cementation is expounded in detail.The swelling mechanism of cemenlired spent resins and preventative measures are discussed.It is pointed out that the cementation formulation has to be given more attention and the key point is to comply with disposal requirements.Finally,comments and suggestions for optimizing the management of spent resins are addressed.
