Study on three-dimensional geological modeling of Tamusu high-level radioactive waste disposal repository in Inner Mongolia

Tamusu area of Inner Mongolia is a key research area for site selection of clay rock disposal repository for high-level radioactive waste in China. Three-dimensional geological model can display the distribution pattern of deep underground structure space intuitively and three-dimensional, and it is an effective site evaluation method. In order to ensure the reliability of the geological model, this paper integrates the existing geological plan and 12 shallow seismic profiles to study the three-dimensional geological modeling of Tamusu area. According to the target layer of clay rock and the spatial distribution characteristics of fault structure described by the three-dimensional geological model of Tamusu area, and in combination with the site selection criteria of high-level radioactive waste geological disposal repository in China, the optimal area for a geological disposal repository of high-level radioactive waste is delineated in the southeast of the pre-selected area.
