Abstract

Abstract:

A model test for high-level radioactive nuclear waste repository (HLWR) was carried out to study the GMZ01 bentonite nuclear waste repository in the near field. An axisymmetric model was established, and the full thermo-hydro-mechanical (THM) coupling considered using the finit element method (FEM) software Code-Bright. With the repositories closed, the effect of different degrees of compaction (porosity) on disposal of seepage, stress and temperature were observed. Variations in temperature, saturation, suction, and stress with time on different initial porosity were obtained. The results provide references for the analysis of planning, design, feasibility of China Beishan Nuclear Waste Repository.

Key words: GMZ bentonite, thermo-hydro-mechanical (THM) coupling, variation of compaction degree, finite element method (FEM) software Code-Bright, change of porosity
