Abstract
DECONTAMINATION D'EAUX USEES RADIOACTIVES PAR EVAPORATION ET TRAITEMENT DE LA VAPEUR POUR EN SEPARER LES NUCLIDES RADIOACTIFS. SELON L'INVENTION, ON FAIT PASSER LA VAPEUR PAR DES CHAMPS ELECTRIQUES (FILTRES ELECTROSTATIQUES 30, 30) DANS LESQUELS SONT SEPARES LES COMPOSANTS SOLIDES ET LIQUIDES PRESENTS SOUS FORME D'AEROSOLS. LA VAPEUR EST AMENEE AU-DESSOUS DES FILTRES TANGENTIELLEMENT, EST DEVIEE PERIPHERIQUEMENT VERS LE BAS PUIS REMONTE AXIALEMENT VERS LE HAUT DANS LES FILTRES ELECTROSTATIQUES 30, 30. APPLICATION A LA DECONTAMINATION PAR EVAPORATION DES EAUX USEES RADIOACTIVES.
