ANALYSIS ON CHARACTERISTICS OF BUFFER MATERIALS IN GEOLOGICAL DISPOSAL REPOSITORIES FOR HIGH-LEVEL WASTES IN CHINA AND SWEDEN

China's Nuclear Power Engineering Co., Ltd., Beijing 100840, China

摘要

摘要: 缓冲材料是高放废物地质处置工程屏障系统的重要组成部分。基于瑞典缓冲材料MX-80膨润土的物理性质，对设计要求的主要参数如渗透系数、膨胀力、材料成分开展分析，并以缓冲材料饱和密度作为长期安全性评价指标分析主要影响因素（外间隙宽度、砌块和小球的干密度），为我国高放废物地质处置库缓冲材料的设计提供参考。

Abstract: Buffer materials are important parts of barrier systems in geological disposal of high-level radioactive wastes. Based on the physical properties of MX-80 bentonite, a Swedish buffer material, the design parameters such as permeability coefficients, swelling forces and material composition were analyzed. The saturated densities of buffer materials were taken as the long-term safety evaluation indexes to analyze the main influencing factors (outer clearance widths, densities of blocks and pellets), which could provide reference to design of buffer materials in geological disposal for high-level wastes in China.
