| 摘 要： | 石墨反应堆退役产生大量放射性废石墨,需要处理后处置。废石墨处理技术主要有焚烧、蒸汽热解、水泥固化、自蔓延固化等,只有焚烧和蒸汽重整热解技术可以实现大幅减容。尽管废石墨的处置存在多种观点,但由于废石墨含有大量长寿命核素,只有深地质处置才能确保安全,然而废石墨数量庞大,处置前的大幅减容是必须的。

| Abstract: | A large quantity of radioactive graphite waste has been produced from decommissioning of nuclear reactors,and required treatment and conditioning before their disposal,The radioactive graphite waste treatment technologies mainly include incineration,steam pyrolysis,cement immobilization and self-proagating synthesis.Only incineration and steam pyrolysis can reduce the volume of graphite waste greatly.Although there are several opinions for disposal of graphite waste,only the deep geological disposal is able to ensure its safety because the graphite waste contains long-lived radionuclides.The quantity of graphite waste is so large that reduction of volume is necessary before disposal. |
