Abstract

A process for the recovery of metals from radioactively-contaminated mixed metal scrap which arises on the shutdown of nuclear engineering installations and has a significant content of non-metallic constituents is carried out with separate melting stages for the metals present. After casting, the radioactivity of the metallic components still amounts to about 5% of the initial radioactivity. The waste materials from the melt (slag, fly-ash) are disposed of according to their radioactivity.
