Abstract
Safety device for a fast neutron nuclear reactor, comprising an absorbent element provided with a support head, connected by a disconnectable link to the lower end of an axially mobile vertical maneuvering rod, this absorbent element being capable, after breaking the disconnectable link, falling by gravity from a high position to a low position, in a delimited passage through the reactor core by a box open at its upper end, and arranged in the core between other boxes containing a nuclear fuel, and delimiting in the core cooled by upward circulation of a liquid metal, a central fuel area and a peripheral cover area, which completely surrounds the central area, characterized in that the disconnectable link between the head of the absorbent element and the end of the maneuvering rod is arranged, in the high position of the element, in the upper part, and at least partially in n the interior of the open box, the absorbent element extending in this box in the peripheral cover area outside the central area.
