DESIGN REQUIREMENTS OF BUFFER MATERIALS FOR GEOLOGICAL DISPOSAL REPOSITORIES OF HIGH-LEVEL RADIOACTIVE WASTES IN CHINA

Based on the conception of geological disposal for high level radioactive wastes, combined with the geological conditions of Beishan in Gansu Province and the buffer and backfill materials composed of Gaomiaozi bentonite from Inner Mongolia, the design parameter indexes of buffer materials in geological disposal repositories for high-level radioactive wastes were proposed, which could provide technical reference to corresponding experimental research on buffer materials for geological disposal repositories of high-level radioactive wastes in China.
