Abstract

Perfeccionamientos en conjuntos de combustible nuclear, que comprenden al menos un haz de agujas de combustible alargadas y envainadas, dispuestas paralelamente las unas a las otras según una red regular y una envoltura en forma de caja prismática de sección recta poligonal que contiene este haz y recorrida por un fluido refrigerante, caracterizados porque unas ranuras cortan los diedros formados por las caras de la caja de la envoltura y porque una camisa, mas delgada que la envoltura, es interpuesta entre éste y el haz de agujas sobre una parte al menos de la longitud de esta envoltura.
