Abstract
A method and apparatus for the volume reduction and processing of solid organic waste, in particular ion exchange media from nuclear facilities containing sulfur or chlorine. A method and apparatus for the volume reduction of nuclear waste is disclosed comprising: subjecting the waste to pyrolysis in a pyrolysis vessel, and gasifying the solid pyrolysis residue in a steam reformer to remove residual carbon. A further method and apparatus for the processing of nuclear waste is disclosed comprising: grinding the nuclear waste, addition of iron powder, pyrolysis, gasification of the pyrolysis residue, and combustion in a submerged bed heater. An evaporator cools gases from the submerged bed heater. Off gases from the evaporator are treated by a fiber bed scrubber to remove acids.
