Solute Transport in Deep Geology Disposal of High Radioactive Waste

Abstract

This paper evaluates and analyzes the safety of solute transport as applicable to the deep geology ground water situation at the disposal of high-level radioactive wastes. This basis is consideration for basic safety assessment. Given the coupling effect from T-H-M-C, the EOS1 and EOS2 can simulate the interactions between groundwater and backfill material when brine and freshwater intrude in the vicinity of field, respectively. With the granite in a certain area in the northwest territories the migration media, the 1D multi-channel solute migration model simulates how the nuclides Cs-134, Co-57 and Tc-99more often involved in the study of granite in China migrate in the media. The results show that Cs-134 can migrate at the fastest rate under the specific conditions, while Tc. 99 is at the slowest rate.
