Properties of barrier materials for low-level nuclear waste disposal

A database of the properties of materials which may be used in the construction of engineered barriers for the long-term containment of low-level nuclear waste (LLW) has been created at Brookhaven National Laboratory in Upton, New York. This paper describes what information is available through the database and how to access it. Properties of interest include hydraulic conductivity, sorbtive abilities, corrosion rates, diffusion coefficients, permeabilities, equilibrium distribution coefficients, structural integrity factors and strengths. Information contained in the database was gathered from a literature survey on the properties of potential engineered barrier materials. (author)
