Abstract
Procedimiento para la obtención de polvos de combustible nuclear de composición de isótopos de graduación prácticamente en forma arbitraria dentro del margen de los productos de partida existentes, caracterizado porque los materiales de partida de distinta composición de isótopos, esto es, enriquecimiento, sin mezclar previamente se alimentan en caudal cuantitativo a la primera etapa de procedimiento de los procesos de conversión usuales, que se pueden desarrollar según el principio AUC o bien ADU, y después de éste se siguen elaborando en la forma usual al producto final de grado de enriquecimiento correspondiente.
