Disposal of transuranic and low-level drum waste involves decisions based on transportation restrictions, Waste Isolation Pilot Project - Waste Acceptance Criteria, and regulation resulting from the Resource Conservation and Recovery Act of 1976 and the Washington State Department of Ecology. To support the decisions made concerning final disposition of these wastes, characterization protocols must be established that ultimately aid in defining the environmental impact. Under current methods, Intensive and expensive laboratory analyses are requested to support these decisions. Alternative screening analyses have been investigated to support characterization and reduce costs and sample turn-around times. One promising screening technique involves application of remote Raman spectroscopy for identification of unknown salts, sludges, and solids in wastes. Raman spectroscopy when used with real-time radiography and visual documentation expands the information base available for making real-time decisions for treatment of diverse drummed radioactive solid waste in a waste processing facility. Fourier Transform Raman spectroscopy has been successfully employed to identify oxidizing reagent waste solutions disposed on vermiculite. In addition, it has been proven that low concentrations of material in binary salt mixtures can be detected by using fiber optic remote Fourier Transform Raman spectroscopy. Development of an extensive solid waste libraryis a key element in the deployment of this technology in the process environment of solid waste drums and barrels.
