In the first place, our Purchase Department lists a series of good practices aiming at ensuring the quality of supplies, including the requirement of a specific certificate, where necessary and depending on the sector. In any case, we regularly check compliance with these requirements by means of a laboratory analysis of the purchased raw materials’ chemical composition. At the same time, we rely on a specific procedure to ensure the quality of the purchased scrap, which consists in sorting the material We take care of raw materials according to its format and composition, among many other criteria. We also verify that the materials we purchase, whether supplies or scrap, are free of radioactivity.
