Abstract
Conjunto de combustible nuclear mejorado, del tipo que comprende una pluralidad de elementos de combustible que se extienden verticalmente y tubos de guía mantenidos en una agrupación en la que quedan separados lateralmente por lo menos por un conjunto de rejilla separador celular que se compone de una pluralidad de placas de rejilla ranuradas que se entrecruzan; y dispositivos de acoplamiento extremos inferior y superior que están unidos a los respectivos extremos de los tubos de guía, caracterizado porque comprende una pluralidad de salientes formados en una misma pieza en los tubos de guía y separados longitudinalmente de manera que tales salientes se acoplan al conjunto de rejilla separadora y limitan los movimientos longitudinales del mismo.
