Abstract (en)

[origin: EP0192777A1] The invention relates to treating radioactive waste consisting chiefly of used ion-exchange resin. The ion-exchange resin adsorbs water to swell. It has therefore been difficult to solidify waste maintaining high charging ratio and increased strength. According to this invention, ion-exchange resin is carbonized through thermal decomposition, and a hydrophobic property is imparted thereto. The resin is then solidified after removing gas that is adsorbed by the carbonized resin.
