Abstract
UNA PASTILLA DE COMBUSTIBLE NUCLEAR SE FABRICA MEDIANTE UN PROCESO DE MEZCLA EN SECO, DE POLVO DE DIOXIDO DE URANIO, EL CUAL CONTIENE ENRIQUECEDORES Y OTROS ADITIVOS, CON DISTEARATO DE ALUMINIO. EN UNA CANTIDAD DE 0.1 A 0.4 EN PESO DE POLVO DE URANIO PARA OBTENER UNA BUENA MEZCLA, LA CUAL SE PRENSA EN PASTILLAS VERDES QUE SE CALAIENTAN DENTRO DE LAS PASTILLAS DE AGLOMERADO CONSTITUYENTE RESIDUAL DEL DISTERATO DE ALUMINIO, EL CUAL SIRVE COMO LUBRICANTE EN EL PROCESO DE PRESURIZACION, MIENTRAS EL OXIDO DE ALUMINIO RESIDUAL SIRVE COMO AGENTE DE CONTROL DEL TAMAÑO DEL GRANO DURANTE LA AGLOMERACION.
