放射性废石墨的焚烧处理

石墨用作燃料套管、慢化剂和反射层的反应堆退役后产生大量的放射性废石墨,面临处理。焚烧作为研究较为深入的处理技术之一,可实现其大幅度减容,且产物具有较高的安全性和稳定性。本文介绍了目前典型的焚烧技术有固定床焚烧法、流化床焚烧法、激光焚烧法等,其中流化床焚烧技术在燃烧效率和技术成熟度上具有优势。

Progress in the Incineration Treatment Research of Waste Radioactive Graphite

A large amount of waste radioactive graphite was produced in the nuclear reactor decommissioning and is waiting to be treated.As a treatment technology that has intensively been studied,incineration could reduce the volume of the waste graphite to a large extent,resulting in safe and stable products.The main incineration technologies include the fixed bed incineration,fluidized bed incineration,laser incineration and so on.By comparison,the fluidized bed incineration technology can provide higher combustion...
