Abstract

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.
- high-level radioactive waste,
- geological disposal,
- buffer material,
- thermal analysis
