Abstract

Perfeccionamientos en un conjunto combustible fácilmente desmontable para reactor nuclear, que comprende un haz de barras combustibles paralelas, cuya separación es mantenida por distanciadores, transversales respecto a las barras, y sustituyendo tubos de sostén del conjunto a ciertas barras combustibles, siendo estos tubos de sostén de longitud superior a las barras, y asegurando, en cooperación con placas de extremo transversales, el acoplamiento rígido del conjunto, garantizando asimismo las placas el mantenimiento longitudinal de las barras.
