Abstract

Se ha desarrollado un montaje del tubo de desmontaje para una tubería descendente en un sistema de rocío del núcleo de un recipiente a presión del reactor nuclear, el montaje de tubo de desmontaje incluye: un manguito del alojamiento formado alrededor del montaje en la tubería descendente, en donde existe un hueco anular entre una superficie interior del manguito del alojamiento y la tubería descendente; una cuña superior y una cuña inferior que se pueden insertar en el hueco; un perno de cuña extendido a través del hueco y extendido a través de la cuña superior y la cuña inferior, en donde el perno aplica una fuerza que jala la cuña superior e inferior juntas para asegurar el manguito del alojamiento con la tubería descendente; un pasador superior extendido desde el manguito del alojamiento dentro de una abertura de una sección superior de la tubería descendente y un pasador inferior extendido desde el manguito del alojamiento dentro de una abertura de una sección inferior de la tubería descendente.
