Abstract

L'invention concerne la technique nucléaire. Le dispositif faisant l'objet de l'invention est caractérisé en ce que l'alésage de la barre creuse 6 a un diamètre qui lui permet de s'engager sur l'élément à extraire 4, et qu'à celle des extrémités de la barre 6 qui est orientée vers l'élément à extraire 4, est monté un grappin supplémentaire 10 destiné à coopérer avec la surface extérieure de l'élément à extraire 4, ladite barre ayant une longueur suffisante pour que le grappin supplémentaire 10 atteigne l'extrémité de l'élément à extraire 4 opposée à la tête de celui-ci, quand le grappin principal 7 est engagé sur ladite tête. L'invention s'applique notamment aux réacteurs à neutrons rapides, refroidi par métal liquide.The invention relates to nuclear technology. The device forming the subject of the invention is characterized in that the bore of the hollow bar 6 has a diameter which allows it to engage on the element to be extracted 4, and that of the ends of the bar 6 which is oriented towards the element to be extracted 4, is mounted an additional grapple 10 intended to cooperate with the outer surface of the element to be extracted 4, said bar having a sufficient length for the additional grapple 10 to reach the end of the element to be extracted 4 opposite the head thereof, when the main gripper 7 is engaged on said head. The invention applies in particular to fast neutron reactors, cooled by liquid metal.
