Abstract (en)
[origin: JP2019101035A] To provide a method and structure for preprocessing radioactive waste stored in a base material.SOLUTION: The method comprises the steps of: introducing radioactive waste contained in a container part into a reaction chamber in which a water vapor-containing atmosphere of 200°C or more is set; carrying out the pyrolysis; removing gases from the reaction chamber; and bringing the container part out of the reaction chamber. At least one of the following steps is carried out additionally: introducing oxygen and/or COin the reaction chamber during pyrolysis in quasi-stoichiometric or maximum stoichiometric amount; adjusting water vapor to be introduced into the reaction chamber as a function of oxidizable substance in the exhaust gas; adjusting oxygen to be introduced into the reaction chamber and/or COdepending on oxidizable substance in the exhaust gas; stopping the pyrolysis depending on the oxidizable substance in the exhaust gas; introducing, in a targeted manner, water vapor and/or oxygen and/or COinto the radioactive waste or into a region thereof; and routing, in a targeted manner, water vapor and/or oxygen and/or COinto the reaction chamber.SELECTED DRAWING: Figure 1
