Abstract

Perfeccionamientos en estructuras de elementos combustibles para reactores nucleares con unión por forma sin holgura, entre sus grupos de componentes que constan en cada caso de materiales de diferente dilatación térmica, tales como barras de unión y tubos guía de las barras de mando por una parte, así como rejillas distanciadoras y placas de cabeza o bien placas base por otra parte, caracterizados porque en las barras de unión o bien los tubos guía de las barras de mando, se fijan mediante soldadura puntual, por encima y por debajo del otro grupo de componentes casquillos dotados de salientes o partes de chapa bombeadas del mismo material, hallándose los salientes diametralmente opuestos entre sí y extendiéndose hasta un plano imaginario común entre los casquillos o bien partes de chapa, perpendicular a su eje longitudinal, y porque el otro grupo de componentes se dota de caras de tope situadas en este plano, en las que sientan los salientes.
