Abstract

Pompe de circulation, notamment pour le métal liquide de refroidissement du coeur d'un réacteur nucléaire à neutrons rapides, comportant un ensemble non démontable disposé à demeure dans la cuve contenant le métal liquide, constitué d'un canal d'aspiration, d'un diffuseur et d'au moins un conduit de refoulement. Selon l'invention, l'ensemble non démontable est suspendu à une structure de support, immobilisée par rapport au coeur. La disposition prévue permet notamment de placer la roue centrifuge en position très basse dans la cuve, en limitant ainsi considérablement les risques de cavitation au niveau de son aspiration.
