Abstract

Un mazo perfeccionado de combustible para reactor nuclear que comprende: (a) una placa de amarre inferior; (b) un pluralidad de barras de amarre que tienen cada una un extremo superior y un extremo inferior, estando fijado dicho extremo inferior de cada una de dichas barras de amarre a dicha placa extrema inferior; (c) una placa de amarre superior que tiene una abertura que incluye una ranura de guía radialmente hacia fuera que se extiende a través de dicha placa de amarre superior; (d) un miembro de apoyo de placa en dicho extremo superior fijado a cada una de dichas barras de amarre para apoyar dicha placa de amarre superior; (e) un manguito de bloqueo que tiene una patilla de bloqueo que se extiende radialmente hacia fuera, estando fijado dicho manguito de bloqueo para funcionamiento a dicho extremo superior de cada una de dichas barras de amarre y siendo de una forma tal que pase a través de dicha abertura y ranura de guía en dicha placa de amarre superior, movible dicho manguito de bloqueo giratoriamente entre una posición de sujeción y una posición de suelta, de tal modo que en dicha posición de sujeción dicha patilla de bloqueo se aplique a dicha placa de amarre superior y sujeta dicha placa de amarre superior a dicha barra de amarre; y (f) medios en dicho extremo superior de dichas barras de amarre para retener dicho manguito de bloqueo en dicha posición de sujeción con dicha placa de amarre superior.
