Abstract
Processo per il recupero di metalli utilizzabili senza danni ai sensi delle disposizioni di legge almeno per un, settore di impiego industriale da rottame metallico misto radioattivamente contaminato che si presenta alla chiusura di impianti nucleari e che presenta un notevole contenuto di impurezze non metalliche. La fusione di separazione viene, eseguita con particolari stadi di processo. La radioattività dei componenti metallici dopo la colata è pari ancora solo a circa il 5% della radioattività iniziale. Gli scarti di fusione (scorie, cenerino volatile) vengono smaltiti a misura della radioattività.
