Abstract
Dispositivo para anular circunstancialmente los tubos defectuosos de un generador de vapor de carga nuclear, con la posibilidad de ponerlos en servicio más adelante, caracterizado por comprender un tapón hueco que se introduce por el extremo de un tubo; el mencionado tapón tiene un diestra exterior esencialmente invariable por la mayor parte de su longitud que se encuentra dispuesta en el interior del tubo, con un diámetro ligeramente más pequeño que el diámetro del tubo; el tapón posee un primer extremo cerrado, que entra en el tubo, y un segundo extremo abierto, adaptado para estar enrasado con el extrema del tubo, así como una cinta de metal dúctil dispuesta en una parte del diámetro exterior del tapan, de tal modo que cuando el tapón es expandido para entrar en estrecho contacto con los tubos, el metal dúctil es extrusionado hacia el interior de cualquier rendija constituída por las irregularidades en la superficie de la pared interior del tubo.
