Abstract
Perfeccionamientos en emparrillados de separación para haces de barras combustibles en reactores nucleares, que comprenden un conjunto de dos familias de chapas delgadas, respectivamente paralelas en cada familia y perpendiculares de una familia a la otra para delimitar alveolos de sección cuadrada atravesados cada uno por una barra combustible del haz, comprendiendo cada chapa sensiblemente en el centro de su extensión en la región que delimita a una y otra parte de esta chapa dos alveolos adyacentes, al menos una lengüeta muelle elástica llevada sobre la chapa y constituida por un material diferente del de la chapa, replegándose cada lengüeta muelle sobre sí misma para presentar un perfil en zigzag tal que comprenda al menos dos resaltes apoyados respectivamente contra las barras que atraviesan los dos alveolos, caracterizados porque las extremidades de la lengüeta están dispuestas en el plano de la chapa y ajustadas en ranuras previstas en ésta a fin de mantener la lengüeta, permitiendoa la vez un desplazamiento de sus extremidades consecutivamente a los esfuerzos ejercidos por las barras sobre sus resaltes.
