ANALYSIS ON THE THERMAL FIELDS OF BARRIER SYSTEMS FOR GEOLOGICAL DISPOSAL OF HIGH-LEVEL RADIOACTIVE WASTES IN CHINA

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

摘要

摘要: 高放废物深地质处置是通过天然屏障和工程屏障（包括废物体容器、处置容器和缓冲材料）实现对放射性废物的有效包容和隔离。基于花岗岩处置场址，以高庙子膨润土为缓冲材料，应用FLAC 3D软件开展我国大时间尺度下处置库屏障系统的热学分析，研究放射性废物在衰变释热条件下，处置环境的温度场随时间的演化规律，分析不同导热系数的缓冲材料对处置环境的温度场的影响。

Abstract: Deep geological disposal of high-level radioactive wastes can effectively contain and isolate radioactive wastes by natural and engineering barriers (including waste containers, disposal containers and buffer materials). Based on the granite disposal site, Gaomiaozi bentonite was used as buffer materials, and FLAC 3D software was used to analyze the barrier system of the disposal repository on large time scale in China. The change thermal rules of the thermal field for the disposal environment with time under the condition of decay and heat release of radioactive wastes were studied, and the impact of buffer materials with different thermal conductivity on the thermal field of the disposal environment was analyzed.
