Safety device for nuclear reactor
Description
This invention relates to a safety device for a nuclear reactor, particularly a liquid metal (generally sodium) cooled fast reactor. This safety device includes an absorbing element with a support head connected by a disconnectable connector formed by the armature of an electromagnet at the end of an axially mobile vertical control rod. This connection is so designed that in the event of it becoming disconnected, the absorbing element gravity slides in a passage through the reactor core into an open container

La presente invention est relative a un dispositif de securite pour reacteur nucleaire, notamment pour reacteur a neutrons rapides, refroidi par circulation d'un metal liquide, generalement du sodium. Ce dispositif de securite comprend un element absorbant comportant une tete de support reunie par une liaison deconnectable constituee par l'armature d'un electroaimant a l'extremite d'une tige de manoeuvre verticale mobile axialement, cette liaison etant agencee de telle sorte qu'en cas de deconnexion, l'element absorbant coulisse par gravite dans un passage delimite a travers le coeur du reacteur dans un boitier ouvertAdditional details
