[3C01] A Study on Behavior of Buffer Material into a Neighboring Rock Fracture Considered Density Distribution Change in Buffer Material Based on Particle Diffusion Model
Keywords:High-level Radioactive Waste, Geological Disposal, Rock Fracture, Diffusion Equation, Particle Diffusion Model
In this study, as one of the various studies being conducted toward the implementation of geological layer disposal, we modeled and analyzed the intrusion behavior of the buffer material into the bedrock cracks. The intrusion behavior was regarded as a diffusion phenomenon, and the diffusion equation in the radial direction of the cylindrical coordinate system was analyzed. The intrusion distance showed a tendency to converge over time, and was generally consistent with the actual measurement results.
