Title
(EN) TURBINE-DRIVEN CONTROL ROD DRIVE
(FR) DISPOSITIF D'ENTRAINEMENT DE BARRES DE COMMANDE MU PAR UNE TURBINE
Abstract
(EN) A drive (10) for positioning a control rod (12) in nuclear reactor core (104) is disclosed. The drive includes a turbine rotor (34) joined to hollow spindle (26) in a housing. The spindle has a piston (82) disposed therein and a piston rod (82b) extending therefrom and through a bottom end of the spindle for being joined to the rod. A pressurized fluid is provided into the spindle (26) for exerting a pressure force against the piston (82) for moving the piston for selectively gripping the control rod (12). Interruption of the pressurized fluid to the spindle causes ungripping of the control rod.
(FR) Dispositif d'entraînement (10) servant à positionner une barre de commande (12) dans le c÷ur (104) d'un réacteur nucléaire. Le dispositif d'entraînement comprend un disque de turbine (34) raccordé à un arbre creux (26) dans un carter. L'arbre comprend un piston (82) disposé en son intérieur et une tige de piston (82b) qui s'étend depuis là et passe à travers le fond de l'arbre pour être raccordée à la barre de commande. Un fluide pressurisé est introduit dans l'arbre (26) pour exercer une force de pression contre le piston (82) et pour déplacer le piston de manière à assurer la préhension sélective de la barre de commande (12). L'interruption de l'arrivée du fluide pressurisé dans l'arbre provoque le relâchement de la barre de commande.
