Abstract

Abstract

As an important part of the engineering barrier system of high-level waste geological disposal repositories, the backfill material in the disposal drifts should have appropriate compressibility to limit the upward expansion of buffer materials in disposal holes. Based on the concept of geological disposal of high-level radioactive wastes in China, the interaction between backfill and buffer materials was researched, by combining the relevant research results on candidate buffer materials (Gaomiaozi bentonite) and backfill materials (bentonite-sand mixtures). Based on theoretical calculations, the effect of densities of backfills in disposal drifts on densities of buffers in disposal holes after expansion was analyzed, and the densities of backfills that satisfied compressible requirements were determined.
