An apparatus and method for processing hazardous wastes directly from 55-gallon drums through the use of pyrolysis and steam reforming. The method is based on a pyrolyzer using heat to vaporize organics that are present in the hazardous wastes. The waste is heated in the original drums to avoid the bulk handling of alpha radionuclides and to ensure criticality control. At pyrolysis temperatures, all liquids and organics in the drums will evaporate and volatize. The resulting waste in the drums is a dry, inert, inorganic matrix with carbon char containing radioactive metals. The off-gas produced by pyrolysis mainly consists of water vapor, volatized organics, and acid gases from the decomposition of various plastics and other organics present in the waste drums. The off-gas produced by the pyrolysis is then collected and fed into an off-gas treatment system that is in fluid communication with pyrolyzer operated under oxidizing conditions.
