Outline of Final Research Achievements |
In this study, flow-through experiments and mechanical experiments using rock samples under prescribed pressure, temperature, and pH conditions were conduced to examine the evolution of the physical properties of rocks. Then, a conceptual models were developed to replicate the experimental measurements. Finally, a coupled THMC numerical model was developed to examine the long-term change in permeability of the porous sedimentary rocks that are assumed to be composed purely of quartz. Subsequently, by simulating the burial of high-level radioactive wastes in the deep subsurface, namely, by applying the simulated confining pressure and temperature conditions, the long-term evolution of the rock permeability was predicted.
