Abstract

La présente invention concerne un plot de centrage d'un cœur de centrale nucléaire dans une cuve de réacteur, caractérisé par le fait qu'il comprend un profil hydrodynamique (120, 130) sur l'une au moins des faces avant ou aval du plot (110) pour réduire les instabilités lorsque du fluide de refroidissement circule autour du plot (110).
