高放废物地质处置库粘土岩场址研究现状

THE GENERAL SITUATION OF CLAY SITE FOR HIGH-LEVEL WASTE GEOLOGICAL DISPOSAL REPOSITORY

高放废物地质处置库的围岩选择至关重要,粘土岩由于其自身的优点受到越来越多的关注。本文介绍了国际原子能机构(IAEA)、国际经济合作和发展组织(OECD/NEA)等国际组织关于高放废物选址的规范情况,在此基础上介绍了在粘土岩处置研究方面几个有代表性国家如瑞士、法国、比利时的高放废物处置库的选址情况,所选的粘土岩场址以及所选择的粘土岩的特性研究情况。希望可以为我国高放废物粘土岩场址的选择提供借鉴。

Host medium is vitally important for safety of high-level radiaoactive waste （HLW） geological disposal. Clay, as host media of geological repository of HLW, has received greater attention for its inherent advantages. This paper summarizes IAEA and OECD/NEA＇ s some safety guides on site selection and briefly introduces the process of the site selection, their studies and the characteristics of the clay formations in Switzerland, France and Belgian. Based on these analyses, some suggestions are made to China＇s HLW repository clay site selection.
