摘要
加压贮存和活性炭吸附是目前国内处理压水堆核电站放射性废气最常用的两种方法。以大亚湾核电站和田湾核电站的放射性废气处理系统为例,并结合国内其他核电机组同类系统,分别介绍这两种方法在国内核电站的应用情况,并分析它们各自的优缺点:加压贮存系统结构简单但设备体积庞大,适合处理流量变化较大的放射性废气;活性炭吸附具有安全性高,操作简单的特点,适合于处理流量较小的放射性废气。
Prevailed gas storage system and activated carbon sorption system are tow of the most popular processing for the gaseous radioactive waste in PWR NPPs. The application of the processing were respectively introduced with instance of the systems in Daya Bay NPP and Tianwan NPP as well as the analogous systems in other domestic NPPs, the advantage and shortage of them were also analyzed in this paper. The pressurized gas storage system is simple in components with large volume and suitable to the widely changeable gas flow; while the activated carbon sorption system is more safe and easy for operation and suitable to the small gas flow.
