Double Fracture Systems of Rock Flow for Geological Disposal of the High-Level Radioactive Waste

Abstract:

Based on the diagenesis, classification and its physical, mechanical, and hydromechanical properties of fractured rock, this paper describes the current status of the fractured rock seepage models and their characteristics. Especially from the point of the safety assessment of the geological disposal of the high level radioactive waste, the discrete fracture network model, the equilibrium continuous medium model and the double media continuous model have been elaborated, and has been analyzed and compared with each other. Furthermore, the double fracture systems for rock flow have been introduced as the much better suitable seepage model for the geological disposal of the high level radioactive waste. In the double fracture systems seepage model, the seepage flow is described and reflected by the main fracture system, and the water store property is given by the subordinate fracture system. The appropriate seepage model for the geological disposal of the high level radioactive waste can be achieved through the double fracture systems, combined with the hydrological testing data in site and other geological information.
