  • Method of reducing the volume of solid radioactive waste
    Patent number: 4555361
    Abstract: Combustible, solid radioactive waste, such as paper, plastics, rubber, cloth and wood, are reduced in volume to an ash residue using pyrohydrolysis, a method which combines pyrolysis of the waste in a vessel at temperatures in the range of 500.degree. to 700.degree. C. and gasification of residual carbon with superheated steam. Pressures of 1.0 to 3.5 MPa are used with steam flows in the range 4 to 50 grams/second/cubic meter so that carbon containing components of the waste are removed as gaseous decomposition products in the form of carbon monoxide and hydrogen leaving an ash residue.
