Abstract
In discarding the used ion exchange resin by the demineralizer provided in the cooling system of an atomic reactor, the radioactivity-rich ion exchange resin and the radioactivity-rich crud can be treated separately by introducing 0.5% by weight of sodium hexamethaphosphate into a slurry of the ion exchange resin, irradiating supersonic of 20 to 60 kHz in frequency to the slurry of the ion exchange resin and removing the radioactive crud from the ion exchange resin.
