摘要
对核电站浓缩液的减容处理是放射性废物最小化内容之一。自行开发了桶内干燥工艺流程以及研制干燥装置,并进行了单机、单元和全流程调试。在此基础上进行了冷试验。结果表明,该装置运行平稳,安全;干燥浓缩液的减容比为4,干燥产物含水率为15%左右。说明该装置用于核电站浓缩液的桶内干燥是可行的。
The volume reduction of waste concentrates from NPPs is a required part of the radioactive waste minimization. This paper introduces the design and development of the self-developed in-drum drying process and its prototype. Debugging had been carried out to each individual section,unit and to the whole process,with a cold test at last using simulated concentrates. Experiment results show that the equipment is safe and reliable with a volume reduction ratio about 4% and product humidity about 15%,the concentrates from NPPs can be properly disposed by the in-drum drying equipment
