法国ANDRA放射性废物地质处置可行性研究综述

ANDRA′S FEASIBILITY STUDY ON DEEP GEOLOGICAL DISPOSAL OF HIGH-LEVEL LONG-LIVED RADIOACTIVE WASTE

介绍15a来法国国家放射性废物管理局(ANDRA)为研究地下处置放射性废物而开展的主要研究成果,实验室试验、现场试验和数值模拟结果均表明:ANDRA所研究的在法国东部埋深500m、厚达130m的泥岩岩层具备永久处置核废料的地质条件,从地质和力学角度上介绍该泥岩岩层一些主要特征,并对ANDRA提出的地质处置总体设计方案和不同类型废物处置单元进行系统论述。

This paper presents a summary of the feasibility report-Dossier 2005 on geological waste disposal, which was elaborated by the French National Radioactive Waste Management Agency（ANDRA）. This Dossier covers results from fifteen years of multidisciplinary research on deep waste disposal, with special focus on the 130 m thick argillite formation located in Eastern France at a depth of 500 m. Results from experiments on argillite samples, in-situ underground experiments as well as numerical simulation on the long-term disposal evolution have shown the capacity of the investigated formation to host a radioactive waste disposal and to satisfy the specifications of long-term safety assessment. Main geological and geomechanical features of the argillite formation have been analyzed. Arrangement of waste disposal cells for different kinds of waste and the global disposal architecture are also presented.
