Abstract

Perfeccionamientos en distanciadores para elementos combustibles de reactores nucleares, en los que una multiplicidad de barras combustibles, está sujeta mediante elementos de apoyo que transcurren diagonalmente, preferentemente en mallas cuadradas de una rejilla compuesta de almas dispuestas de canto y ensambladas unas con otras, caracterizado porque por lo menos se dota a dos paredes de malla de almas elásticas dispuestas diagonalmente, abombadas penetrando en el espacio de la malla, y por lo menos dos paredes de malla van provistas en cada caso de por lo menos un botón rígido.
