Transport and retardation parameters of radionuclides, which are needed to perform a safety analysis for a deep geological repository for radioactive waste in a compacted claystone such as Opalinus Clay, must be based on a detailed understanding of the mobility of nuclides at different spatial scales (laboratory, field, geological unit). Thanks to steadily improving experimental designs, similar tracer compositions in different experiments and complementary small laboratory-scale diffusion tests, a unique and large database could be compiled. This paper presents the main findings of 20 years of diffusion and retention experiments at the Mont Terri rock laboratory and their impact on safety analysis.

在蒙特特里岩石实验室(瑞士)探索扩散和吸附过程:从20年现场研究中汲取的经验教训

放射性核素的输运和阻滞参数,是对压实粘土如Opalinus粘土中的放射性废物的深层地质处置库进行安全分析所必需的,必须基于对不同空间尺度上核素迁移率的详细了解(实验室) ,字段,地质单位)。由于稳步改进了实验设计,在不同实验中使用了相似的示踪剂以及补充了小型实验室规模的扩散测试,因此可以编译一个独特的大型数据库。本文介绍了在Mont Terri岩石实验室进行20年扩散和保留实验的主要发现及其对安全性分析的影响。
