Abstract

L'invention a pour objet un dispositif de commande d'une barre de contrôle d'un réacteur nucléaire muni de sécurités contre l'éjection et le chavirement. Ce dispositif du type comportant une enceinte étanche solidaire du couvercle de fermeture du réacteur, un système vis-écrou lié à la barre par l'intermédiaire de l'écrou et un dispositif d'accrochage de la vis apte à libérer cette dernière se caractérisé en ce qu'il comporte un ensemble pour limiter puis bloquer la remontée de la barre lors d'une rupture de ladite enceinte étanche, cet ensemble comprenant des moyens pour limiter le déplacement ascendant de la partie rompue de ladite enceinte sous l'action d'une poussée verticale résultant de ladite rupture, des moyens pour bloquer en rotation ledit rotor et des moyens élastiques tarés agissant sur le rotor à l'encontre de ladite poussée verticale. Application à la réalisation de dispositifs de commande de barres de contrôle.
