The nuclear power has brought a lot of convenience for the life, But its arising from used nuclear fuel is one of the big problems of environmental pollution, So for the disposal of used nuclear fuel it will be an important issue. For the final disposal of used nuclear fuel, must be sufficient to prevent the spread of pollutants to the biosphere.
There are many country studying and evaluation about this issue, they consider that the deep geological disposal is the most safe and feasible measure. The study will analyze on this concept.
This study will use the deep geological disposal model of Japan reference (JNC H12) and finite element method to analyze. During the analysis, the study is directed against the disposal of the overpack corrosion expansion analyzed.
The study is divided into three parts. First, the verification of coupled thermo-hydro-mechanical without overpack corrosion expansion effect. Second, the verification of overpack corrosion expansion , and the materials included buffer and overpack. Third, the analysis of coupled thermo-hydro-mechanical and overpack corrosion expansion effect. The above analysis may provide future disposal sites when analyze of the situation needed to consideration.
