On the basis of published information and data, the four principal radioactive waste calcination techniques, fluidized bed, the pot, the radiation-heat spray, and the rotary-ball kiln, are examined and compared with respect to the principal process, operational, and product characteristics of each. An ultimate combined capacity of 1000 to 2000 gph is shown to be necessary to process generated and accumulated wastes between the years 1965 and 2000. The effects on product properties and on economics of ultimate waste disposal of the type of calciner selected are considered from many standpoints, including the composition, concentration, and activity level of the waste solution and the calcination conditions. Also discussed are creation of glass-like compounds from calciner products, personnel and equipment requirements, and the present status of development of each of the calciners. It is shown that one or more calciners may be suitable to process any particular waste, depending on the desired type of product and other circumstances. (auth)
