Abstract: A complex electrokinetic decontamination equipment is disclosed, which removes a radionuclide from contaminated soil with a high efficiency, using a combination of a washing decontamination method performed in an electrokinetic unit using electrolyte and an electrokinetic decontamination method performed by the electrokinetic unit. pH values in an anode chamber and a cathode chamber are optimally controlled by a pH control unit, thereby reducing quantity and size of metal oxide particles. In addition, a water level of the electrolyte in the electrokinetic unit may be automatically controlled by an electrolyte supply controller.

Abstract: A method and an apparatus for electrokinetically decontaminating the soil contained in a radioactive waste drum are disclosed. The radioactively contaminated soil is put into drums, and the drums are carried to a temporary storage or to a disposal site. If the extremely low level radioactive soil is decontaminated rather than carrying the soil to the temporary storage or to a disposal site, and if the decontaminated soil is returned to the nature, then the limited storage capacity can be saved. Further, if a high level radioactive soil is treated to a low level one, and if thus a low level radioactive soil is stored in a storage, then the safety is improved. In the present invention, electrodes are buried into the contaminated soil contained in a radioactive waste drum, and a dc current is supplied, so that the radioactive nuclide and impurities can be removed by the electroosmosis and the electromigration.
