Abstract: The invention relates to nuclear technology and can be applied for decontamination of metallic surfaces of equipment in nuclear power plants. The material, with metallic surface contamination, is placed in a container; Movable electrode, with gap according to the contaminated surface, is installed; Connect the material and the electrode to the terminals of pulse generator. Then water is poured into the gap and the electric arc is ignited. The high temperature, caused by the arc, melts the metallic surface. Under the force of the electro-shock, occurs a quenching of the discharge, wherein the molten metal is ejected out of the hole and granulated in cold water.
