Abstract

Abstract

Backfill materials in disposal drifts are important engineering barriers in geological disposal repositories of high-level radioactive wastes; a certain installed dry density is required to meet its barrier function. Based on the concept of geological disposal of high-level radioactive wastes in China and the design concept of backfill materials, the sensitivity analysis of factors affecting installed densities of backfill materials by combining the reference design of backfill blocks and pellets was carried out. It was found that block dry densities and filling degree were the dominant factors. Then, combining the design requirements of the installed dry densities for backfills, feasible plans to meet the requirements were proposed on an analysis of 36 possible installation schemes. The study could provide technical reference to related experimental research of backfills in geological disposal repositories of high-level radioactive wastes in China.
