Laboratory equipment is being assembled for the investigation of unusual particulate and gaseous radioactive material in the incinerator offgas when commercial wastes are incinerated. This equipment will constitute a bench-scale incinerator system with monitoring equipment to effect the investigation. A literature search was made to determine the current technology used in removing the expected effluents from gas streams. A series of controlled-feed incinerator runs was performed to determine the mass balance of chloride in the Cyclone incinerator system. Approximately 74% of the chloride present in the feed material was found to be in the scrubber solution, 8% in the flue gas, and the remaining chloride was distributed in the ash and retained in the system. A conceptual design was prepared and modifications were begun on a glove box which is to be used for the demonstration phase of incinerator ash immobilization. Concrete and cold-pressed pellets are being studied and compared for ash immobilization
