<p>In a method of treating zirconium of a zirconium waste composed of zirconium or zirconium alloy or a spent fuel through an oxidation treatment with electrolysis, a nitric acid solution is used as an electrolytic solution and the electrolytic solution is heated at a temperature of preferably more than 60{C so as to improve an electrolytic rate. The electrolytic solution is agitated by an ultrasonic generator to recover an oxide generated by an electrolytic treatment without hindering electrolysis and to make uniform an electrolytic state. In modifications a zirconium oxide film formed on the surface of the zirconium is continuously exfoliated while electrolysing and irradiating with ultrasonic waves. Alternatively the zirconium waste may be impacted, or agitated.</p> |
