This paper focuses on the mechanical and hydraulic properties of simulated contact handled transuranic radioactive waste that are associated with the Waste isolation Pilot Project (WIPP). In particular, the mechanical behavior of the simulated (nonradioactive) waste and its permeability after substantial time dependent compaction are being measured to give input data for modeling contaminated brine flow in a geologic repository stratum. A number of deformation and permeability tests have been performed on materials comprising this waste. A variety of material mixtures were used, including cloth, wood, metals (various geometries), plastics, and minerals (various grain size distributions). Prior to the permeability tests, specimens were loaded under a constant stress (2000 psi) from 1 to 50 days and allowed to achieve a stable density state. Specimens, four inches in diameter with various lengths, were loaded axially via a piston and confined radially by the pressure vessel cylinder wall. Axial deformation was measured for production of stress-density and density-time curves. Subsequent to the deformation stage, which was terminated after evidence of density stabilization, brine was passed through the specimen for permeability measurements. Deformation and permeability measurements of the simulated waste material are presented. Permeability values ranged through several orders of magnitude. 3 refs., 5 figs., 2 tabs.
