ABSTRACT:
A method and apparatus for the treatment of waste materials including nuclear contaminated materials is disclosed. The method of the invention includes the steps of: grinding the base material until the maximum grain size is 50 millimeters; drying the ground material to a relative humidity content below 30%; distilling the material at a core temperature of 100.degree.-1200.degree. C. on a negative pressure from 200 N/m.sup.2 to an over pressure of 300 kN/m.sup.2 in an oxygen free, reducing, indirect heated environment; burning or cooling the vapors arising; treating the remaining solid materials by combustion, mineralization, vitrification, or solidification; and pelletizing or granulating the remaining ash. The apparatus of the invention includes a dry distillation reactor that has a rotary, closed, horizontally arranged cylinder with hollow axes on the ends. The axes are separated from input and output houses by seals. The input house is provided with a loading opening and a gas exit branch. The output house is provided with an unloading opening and a gas exit branch. The ends are sealed by sealing segments placed on the axes and sealing rings placed between the sealing segments and the walls of the input and output house.
