摘要: 核电厂产生的放射性废塑料种类较多, 现多采用压缩和焚烧技术进行处理。其中, 压缩会出现爆桶和压饼反弹, 导致废物体积增大; 焚烧产生有毒有害气体, 污染环境。本文提出一种放射性废塑料处理新工艺, 采用“分拣—破碎—熔融—预压—自然凝固”工艺处理放射性废塑料, 并设计出配套设备。经对工艺参数进行分析和调试, 该工艺处理放射性废塑料的减容比可达15.4。

Abstract: There are many kinds of radioactive waste plastics produced by NPPs, which are now mostly treated by compression or incineration. While compression may cause drum burst and pellet rebound, resulting in waste volume increase; incineration produces toxic and harmful gases that pollute the environment. A new process is proposed, which adopt a flow of sorting, crushing, melting, pre-pressing and natural solidification, and supporting equipments are designed. After analysis and debugging of parameters, the volume reduction ratio of the process to treat radioactive waste plastics can reach 15.4.

Key words: Radioactive waste plastics, Volume reduction ratio, New process, Parameter
