[en] Data resource is the important foundation for the research and development of repository site selection, safety assessment, and engineer construction for the geological disposal of high-level radioactive waste (HLW). The development and utilization of data source is a long-term, systematic and scientific project due to its typical characteristics of big data. In this paper, the strategies, methods and current situation of data resources integration for HLW geological disposal were briefly introduced. The specific characteristics of scientific data generated during the research and development of HLW geological disposal were described and the planning ideas of big data platform was proposed for the geological disposal of HLW in China. The integrated development status of geological information in the preselected areas was introduced with emphasis for HLW geological disposal. (authors)
