Abstract

Procédé de décontamination de mitraille de fer et/ou d'acier qui a été contaminée par radioactivité, en faisant fondre la mitraille en présence d'agents de scorification du bain de fusion de fer/acier. Pour réduire la radioactivité résiduelle, on ajoute en plus des isotopes inactifs des éléments radioactifs se trouvant dans le bain et on les soumet au processus de fusion pour que les isotopes radioactifs des éléments soient chassés du bain et transférés dans le laitier qui est séparé du bain, celui-ci possédant une radioactivité suffisamment faible pour la réutilisation du fer ou de l'acier.Process for decontaminating scrap iron and / or steel which has been contaminated by radioactivity, by melting the scrap in the presence of slagging agents from the iron / steel melting bath. To reduce residual radioactivity, radioactive elements in the bath are added in addition to the inactive isotopes and subjected to the fusion process so that the radioactive isotopes of the elements are removed from the bath and transferred to the slag which is separated from the bath. , the latter having a radioactivity low enough for the reuse of iron or steel.
