A flyash-based barrier layer/cover system instead of bentonite-only one is proposed in this research. This paper describes the current system and technology for radioactive waste disposal and then proposes and discusses the applicability of flyash as a content of barrier layer/cover material based on the results of a series of laboratory tests and numerical analysis. The applicability of flyash to the contents of barrier layer/buffer for radioactive wastes was investigated in this research. From the results of a series of laboratory tests, it can be concluded that flyash has a great potential for use in them as the bentonite is substituted (substitution ratio : 30-40%).

在这项研究中，提出了一种基于粉煤灰的屏障层/覆盖系统，而不是只有一个蛭石。本文介绍了目前放射性废物处置的系统和技术，然后提出并讨论了粉煤灰作为屏障层/覆盖材料的内容物的适用性的基础上，一系列的实验室试验和数值分析的结果。研究了粉煤灰作为放射性废物阻挡层/缓冲层材料的适用性。通过一系列室内试验结果表明，粉煤灰替代膨润土（取代率30-40%）具有很大的应用潜力。
