ABSTRACT:
Installation for handling the assemblies of a fast neutron nuclear reactor comprising a core located in a vertically axed vessel and constituted by a group of assemblies positioned in a supporting grid, a horizontal slab over the vessel, a large rotary plug in the slab, a small rotary plug in the large rotary plug and off-centered with respect to the latter, and a handling pot or container making it possible to remove the fuel elements from the vessel, wherein the small rotary plug has a handling poker and the large rotary plug positioned coaxially with respect to the core has a handling arm, the poker making it possible to reach a fraction of assemblies, particularly those in the central part of the core and to transfer them into a take-up station of the supporting grid, the assemblies placed in the take-up station, as well as those in the peripheral area downwardly accessible to the handling arm being deposited by the latter in the handling pot or container.
