Stevens, J. I.

The costs of fluidized bed calcining of the acidic and re-acidified forms of Purex and Thorex wastes were determined. The wastes were assumed produced by a chemical-processing plant recovering unburned fuel from 1500 tons/ yr of U converter fuel at a burnup of 10,000 Mwd/ton and 270 tons/yr of Th converter fuel at 20,000 Mwd/ton. Also, investment costs for storage of the calcine in vented, air cooled, annular bins installed in underground concrete valuts were determined. The cost of fluidized bed calcining was determined at processing rates of 45, 80, and 75 gph for solids storage in bins varying from 3 to 22 in. thick and installed in underground concrete vaults containing 4, 12, 20, and 40 nested annular bins, each nest with an overall diameter of up to 12.5 ft. Aging had negligible effect on costs, except as it permitted thicker bins to be used. The lowest cost, 0.47 x 10/sup -2/ mills/kwh/sub e/, was for processing acidic Purex and Thorex wastes at 75 gph with storage in an underground concrete vault contnining 40 of the 12.5-ftdia. nested bin arrays. And the highest cost, 2.9 x 10/sup -2/ mills/kwh/sub e/, was for processing reacidified Purex and Thorex wastes at 45 gph with storage in an underground concrete vault containing 4 nested bin arrays.
