ABSTRACT:
Mixed waste containing organic constituents and low level radioactive waste is remediated in a circulating fluidized bed combustor. Three separators are used to filter the flue gas and separate fine radioactive material from coarse non-radioactive material thereby concentrating the radioactive portion. A primary separator separates large material such as sand, lime, flyash or unburned fuel particles from the flue gas leaving the furnace of the combustor. The flue gas is then passed to a secondary separator for the collection of finer particles. In turn, the flue gas is passed to a tertiary separator for the collection of the finest particles of the flue gas containing low level radioactive waste. Solids entrained in the primary separator are recycled back into the bed of the combustor through an L-valve. Solids entrained at the secondary separator are also recycled back into the bed.
