The alternative retrieval process of confined sluicing is currently being evaluated for retrieving waste from tank A-105 at the Hanford site, which is a single-shell tank known to have previously leaked due to a tear in the tank liner. This report gives a summary of the key waste properties for defining performance based simulants for evaluating confined sluicing and evaluates existing information on A-105 waste to define preliminary estimates for the likely ranges of these key waste properties. Previously developed simulants are assessed, in comparison to A-105 waste, to determine if they are suitable for representing A-105 behavior in planned testing of confined sluicing and/or if new simulants need to be developed.
