Abstract:
1. A method for at least partially decontaminating solid waste that is contaminated with at least one radionuclide, wherein waste having a matrix made of non-radioactive base material is selected, in which the radionuclide is embedded, wherein: a) the waste is mixed, or brought in contact, with at least one corrosive medium, which is inert with respect to the base material before the activation energy is supplied, wherein at least one binary metal oxide, sulfate, nitrate, hyroxide, carbonate, hydride, halogen succinimide and/or a peroxide, an acid, a lye, a completing agent and/or an electrolyte, and/or another reagent that can be pyrolyzed and/or dehydrated is selected as the corrosive medium and then b) activation energy is supplied to the corrosive medium, so that hydrogen or hydrogen ions, oxygen or oxygen ions, and/or halogen or halogen ions, and/or nitrate and/or sulfate ions, and/or carbon dioxide, and/or water vapor are formed from the corrosive medium, and as a result of these products thus formed: c) at least a portion of the radionuclide present in the waste is converted into at least one gaseous reaction product or is dissolved.
