Title

(ES) Una pastilla de combustible nuclear sinterizada, una barra de combustible, un conjunto de combustible y un método de fabricación de una pastilla de combustible nuclear sinterizada

Abstract

(ES) Una pastilla de combustible nuclear sinterizada (10), que comprende una matriz (20) de UO2 y unas partículas (21) dispersas en la matriz: en donde las partículas (21) comprenden un material que contiene uranio (22), en donde cada una de las partículas (21) está encapsulada por un recubrimiento metálico (23), en donde el material que contiene uranio (22) tiene una densidad de uranio que es más alta que la densidad de uranio del UO2, caracterizada por que el recubrimiento metálico (23) consta de al menos un metal elegido del grupo de Mo, W, Cr, V y Nb.
