Designing a solidification/stabilization process for a fine powder mixed radioactive waste
A fine powder radioactive mixed waste was generated during cleanup of the Colonie Interim Storage Site (CISS) near Albany, New York. This site is being remediated by Bechtel National as part of the Formerly Utilized Sites Remedial Action Program for the U.S. Department of Energy. The waste, high-efficiency particulate air (HEPA) vacuum dust, must be treated before disposal at Envirocare, Utah. The treated waste must pass the toxicity characteristic leaching procedure (TCLP) test in order to meet treatment standards for land disposal. The primary contaminants of concern are lead and cadmium. Portland cement, portland cement/silica fume, portland cement/soluble sodium silicate, Envirostone{reg_sign} gypsum cement, Fluid Tech{reg_sign} materials, sulfur cement, and vinyl ester resin were all examined and tested as potential solidification/stabilization agents. Bench-scale test results are presented, and a process design using portland cement with silica fume and water reducing admixtures is recommended for a small-scale application.
