The Process Experimental Pilot Plant (PREPP) incineration system is designed for processing mixed (chemical and radioactive) hazardous waste. The facility accepts solid waste contaminated with alpha emitting transuranics (TRU) and incidental quantities of hazardous materials such as solvents and lubricants. PREPP consists of a shredding and feed system for containerized waste, a rotary kiln incinerator with a secondary combustion chamber, an ash cooling and grouting system, and wet offgas cleaning system followed by two stages of HEPA filtration. The facility has underground an extensive test period where a number of improvements to the process and equipment have been identified. The incinerator feed system, ash discharge system and the sludge handling system are areas where improved performance is desired. 6 figs.
