A deep repository located in Hanford basalt has been proposed for the disposal of high-level nuclear waste. Backfill materials are required to make up the backfill component of a multiple barrier waste package and to fill the rooms, tunnels, and shafts of the repository sealing system. The major emphasis of this paper is the backfill component of the waste package. However, much of the discussion is applicable to the repository sealing system. The functions, material properties, candidate materials, and testing methods for backfill are discussed. Because of the variety of backfill functions, physical, mechanical, and chemical properties are required of an adequate backfill. Therefore, a multicomponent backfill will probably be needed. The geochemical environment of the basalt site and the physical and chemical reactions that are likely to occur in the near-field environment have been used to derive the essential testing needs. 4 tables.
