Abstract

Procédé et appareillage de commande et de régulation du flux de neutrons d'un réacteur nucléaire. L'appareillage comprend une barre de commande qui comporte une surface d'étanchéité. La barre passe par un orifice d'une plaque de séparation qui comprend une surface d'étanchéité portant contre une surface d'étanchéité de cette barre. La différence de pression produite par la circulation d'un fluide de redroidissement dans le reacteur a pour résultat d'appliquer la barre contre la plaque de séparation. En cas de réduction du débit de ce fluide, la réduction de la différence de pression qui en résulte provoque une séparation desdites surfaces d'étanchéité et la chute de la barre de commande Application à la commande des réacteurs.
