放射性废树脂处理技术研究进展

Research progress of radioactive spent resin treatment

本文介绍了各种放射性废树脂处理技术的工艺原理、优缺点和研究进展。放射性废树脂的处理技术可分为水泥、沥青、聚合物等固化法,热态压实和桶内微波干燥等脱水减容法以及焚烧、湿法氧化或蒸汽重整等氧化分解减容方法。通过分析不同处理技术的特点,发现放射性废树脂处理具有前景的研究方向为设计和开发操作条件温和、效率更高的氧化分解减容工艺。

This article introduces the process principles,advantages and disadvantages,and research progress of various treatments for radioactive spent resin.The treatment technology of radioactive spent resin can be roughly divided into solidification methods such as cement,asphalt,polymers,etc;dehydration and volume reduction methods such as hot compaction or microwave drying in barrels,as well as oxidation decomposition and volume reduction methods such as incineration,wet oxidation,or steam reforming.By analyzing the characteristics of these treatments,it is found that improving the efficiency of oxidative decomposition volume reduction process under mild operating conditions might be future research directions in radioactive spent resin treatment.
