Modified Synroc B Ceramic Containing Simulated High Level Waste Characterization During Leaching

Abstract

The chemical stability of Snyroc-B ceramic containing simulated radioactive waste was determined by leaching experiments. Samples were characterized by leach rates (μg cm^-2 day^-1) determined from atomic absorption analysis of leachant solution after exposure to the samples for various times. The stability was also examined by observation of the sample surfaces and by surface area determination of the powdered samples. Results are also expressed in terms of an accumulated eroded layer. Overall observations confirm previous reports of the high stability of this form of solid radioactive waste disposal material.
