Radioactively contaminated material is cleaned by contacting the material with a decontaminating liquid comprising an aqueous solution of nitric acid containing an NOx generating agent. The NOx generating agent may by a nitrite, for example, sodium nitrite, or a ferrous metal. The material to be cleaned may comprise a plastics material contaminated with uranium or other actinides. Cleaning is effected by placing the material in a rotatable, apertured vessel in which the material is subjected to a leaching cycle by contact with the decontaminating liquid and then a washing cycle in which the material is contacted with a washing liquid.
On nettoie le matériau radioactivement contaminé en le mettant en contact avec un liquide de décontamination comprenant une solution aqueuse d'acide nitrique contenant un agent générant du NOx. Cet agent peut être un nitrite, tel que du nitrite de sodium, ou un métal ferreux. Le matériau à nettoyer est un matériau plastique contaminé par de l'uranium ou d'autres actinides. Pour nettoyer le matériau considéré, on le place dans un récipient rotatif à orifices dans lequel le matériau subit un cycle de lixiviation consistant à mettre le matériau en contact avec le liquide de décontamination, puis un cycle de lavage consistant à mettre le matériau en contact avec le liquide de lavage.
