摘　　要：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。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 efficiency and technology maturity.
