Abstract
METODO PARA DESCONTAMINAR PRODUCTOS DE CORROSION CONTAMINADOS CON RADIONUCLIDOS, QUE SON DIFICILMENTE SOLUBLES EN ACIDOS, DE SUPERFICIES DE SISTEMAS PRIMARIOS EN REACTORES DEL TIPO DE REACTOR DE AGUA A PRESION Y DEL TIPO DE REACTOR DE CALDERA CON DOSIFICACION DE HIDROGENO Y SIMILARES, POR OXIDACION Y DISOLUCION SIMULTANEA, EN UNA SOLUCION ACIDA DE DESCONTAMINACION, DE LOS PRODUCTOS DE CORROSION SOLUBLES EN ACIDOS OBTENIDOS POR MEDIO DE DICHA OXIDACION. LA PROPIEDAD CARACTERISTICA DEL METODO ES QUE DICHA OXIDACION SE EFECTUA CON IONES CEBS4+, OZONO Y ACIDO CROMICO EN PRESENCIA DE ACIDO PERHALOGENICO, PREFERIBLEMENTE ACIDO PERCLORICO, A UN PH INFERIOR A 3.
