Description/Abstract:
This report contains data for waste minimization and substitution projects for the Y-12 Plant from 1973 to 1994. Eight projects completed for the Y-12 Plant from 1973-1978 were (1) recycle of nitric acid; (2) recycle of aluminum nitrate, (3) substitution of chromium in cooling towers; (4) reduced number of machine coolants; (5) extended life of acid pickle baths; (6) minimized depleted U release to Poplar Creek; (7) minimized HF usage; and (8) shipped sodium hypochlorite to Knoxville Sewage Plant. From 1979-1983, a summary included the reduced purchase of trimsol concentrate; reduced disposal/treatment of est. 190,000 gal/yr of spent coolant; reduced purchase of est. 24,000 lb/yr of sodium nitrate; and eliminated treatment/disposal of 24,000 lb/yr of sodium nitrate. Minimization and substitution efforts for 1983-1988 were the purchase of chemicals reduced from nominal 8.4 million lb/yr to 5 million lb/yr; 20 percent decrease in production work load had occured; purchase costs were estimated to average $0.40/lb ($2 million) and disposal cost were estimated at $4.00/lb ($20 million); and many processes were changed to reduce chemicals. It also listed the top ten chemicals purchased by the plant in 1984 and other material purchases. The future programs for 1989-1994 involved nitric acid and aluminum nitrate, process changes at WETF, and the depleted uranium program.
