Abstract

L'invention concerne un appareil pour réparer à distance des tubes montés sur une plaque tubulaire dans une tête de canalisation d'un générateur à vapeur ayant un passage d'homme disposé dans cette tête. Cet appareil comporte une colonne supportée à pivotement et de façon amovible dans cette tête de canalisation généralement perpendiculaire à la plaque tubulaire, une flèche montée à pivotement sur cette colonne, un dispositif pour faire tourner la colonne et la flèche avec elle ainsi qu'un dispositif pour faire tourner cette flèche d'une position généralement parallèle à la plaque tubulaire à une position généralement en alignement avec l'axe du passage d'homme. Application aux réacteurs nucléaires à eau sous pression.An apparatus for remotely repairing tubes mounted on a tube sheet in a pipe head of a steam generator having a manway disposed therein. This apparatus comprises a column supported pivotally and removably in this pipe head generally perpendicular to the tube plate, a boom pivotally mounted on this column, a device for rotating the column and the boom with it as well as a device to rotate this boom from a position generally parallel to the tube sheet to a position generally in alignment with the axis of the manway. Application to pressurized water nuclear reactors.
