A conceptual waste treatment plan comprises sorting the metal scrap into alloy types, size reduction of the scrap to fit in the melting equipment, further alloy segregation by sequentially raising the temperature of mixed scrap lots and allowing the low-melting alloys to drip-melt out, induction melting of the high-melting alloys, and casting all alloy type into ingots. Laboratory melts of various metals were made to compare the observed partitioning of uranium to the slag with thermodynamic calculations. An engineering-scale demonstration was also conducted in which typical metal scrap contaminated with UO/sub 2/ was processed by mechanical size reduction, drip melting, and induction melting. Results show decontamination was successful. 5 figures, 2 tables. (DLC)
