摘要
高放废物的安全处置是全球核工业领域所面临的一项重大课题,而深地质处置方法被国际社会所普遍接受,其中深钻孔处置目前受到广泛关注。通过对高放废物源项进行分析并结合深钻孔处置的特点,提出了适合深钻孔处置的废物源项特征,认为深钻孔处置方式可以用来接收高放玻璃固化体以及乏燃料废物。其中,高放玻璃固化体由于其处置容器直径较大,对深钻孔的钻探技术提出了巨大挑战;而乏燃料组件由于截面较小,满足深钻孔处置要求,但对于乏燃料后期回取问题,尚需进行大量的研究工作进行论证。
The safe disposal of high level radioactive waste is an important issue that the global nuclear industry has to be faced with. Deep geological disposal has been widely accepted by the international community,and the deep borehole disposal has been paid great attention recently as one method of the deep geological disposal. In order to provide reference for the design of deep borehole disposal,based on the analysis of high level radioactive waste sources and the characteristics of deep borehole disposal,the paper put forward the characteristics of waste sources which were suitable for deep borehole disposal. The results showed that the deep borehole disposal could be used to dispose high level radioactive vitrified waste and spent-fuel waste. Due to the larger diameter of the treated container of the high level radioactive vitrified waste, the drilling technique of deep borehole disposal faced enormous challenges. The smaller cross-section of spent-fuel components could meet the requirements of deep borehole disposal.However,a large amount of research work is needed to demonstrate the problem of later retrieval of spent fuel.
