Abstract
EL INVENTO DESCUBIERTO ES UNA MEJORA EN LA EXTRACCION DE SOLVENTE "PUREX", Y EL PROCESO DE SEPARACION PARA RECUPERAR URANIO DE MATERIAL DE DESHECHO O FUEL PASADO, COMPRENDIENDO TRATAR EL URANIO QUE CONTIENE EL DESHECHO O FUEL PASADO CON ACIDO NITRICO PARA CONVERTIR EL URANIO A NITRATO DE URANIO SOLUBLE, EN UN MEDIO ACUOSO, SEPARANDO EL URANIO DEL MEDIO ACUOSO CON UN MEDIO ORGANICO QUE CONTIENE FOSFATO TRIBUTIL; ENTONCES LIBERAR EL URANIO SEPARADO DEL MEDIO ORGANICO CON AGUA. LA MEJORA COMPRENDE CONTROLAR LA DENSIDAD DEL MEDIO ORGANICO Y CONTROLAR LA PROPORCION DE ALIMENTACION DEL URANIO EN EL MEDIO ACUOSO EN RESPUESTA A LAS MEDICIONES DE LA DENSIDAD
