Abstract

Perfeccionamientos en los tubos guía de combustible, para reactores nucleares, del tipo que tiene una pluralidad de elementos de combustible y por lo menos un tubo guía que se extiende longitudinalmente en paralelo y separado lateralmente por órganos de rejilla que intersepta definiendo dicha separación lateral unos canales de flujo de refrigerante, caracterizados por la provisión de un saliente integral que proyecta la superficie exterior del tubo guía en un canal contiguo de flujo de refrigerante, de modo que desvía parte del flujo del canal contiguo de flujo de refrigerante hacia una abertura definida por la menor distancia lateral entre un tubo guía y un elemento de combustible contiguo.
