Outline
Deep geological disposal is currently internationally recognized most technically feasible method for the safe disposal of high-level radioactive waste. The chemical characteristics of groundwater at the disposal site are crucial for the design of engineering barriers and safety assessment of the disposal facility. This paper summarizes and compares the research achievements in groundwater chemistry，isotopes，and groundwater chemical modeling in the United States，Sweden，Finland，Switzerland，and France. Combining the foreign achievement with the current research status of high-level radioactive waste geological disposal in China，the paper proposes that China need to conduct further research on aspects such as the vertical distribution of groundwater chemistry at the site，groundwater microorganisms, dissolved gases in groundwater, the redox conditions of the site, and the paleoclimate of the site. Based on the above achievement，a hydrogeochemical model of the disposal site should be developed to evaluate the safety and stability of the disposal site at a timescale of tens of thousands years. This study aims to provide a reference for China’s research on groundwater chemistry at high-level radioactive waste disposal sites.
