A fast neutron nuclear reactor having a vessel filled with liquid metal and sealed in its upper part by a box slab having a central opening in which is placed a plug-cover-core overhanging the core of the reactor. The central opening is surmounted by a cell containing the handling and storage mechanism for the plug-cover-core and a mechanism for handling the assemblies. The latter can be moved on annular rails and can be collapsed against the wall of the cell, in order to permit the manipulation of the plug-cover-core. A radial passage connects the cell to a transfer station.

Fast neutron nuclear reactor equipped with a central handling cell and a

Apparatus for homogenizing the circumferential temperatures of the vertically axes ferrule of a component passing through the upper slab of a nuclear reactor, wherein it comprises at least one assembly forming a heat pipe describing the entire circumference of said ferrule in order to ensure the homogenization of the temperatures of said ferrule level with the assembly, means for fixing the assembly or assemblies forming the heat pipe on the inner face of the ferrule and means for ensuring a thermal contact between the assembly or assemblies forming the heat pipe and the said ferrule.

Temperature homogenization apparatus

Integrated nuclear reactor cooled by a liquid metal and constituted by a n tank, which contains a central inner tank containing the core and the hot liquid metal, this inner tank being connected to individual cylindrical chambers each containing a heat exchanger wherein the surfaces of the inner tank and of the cylindrical chambers bulge radially outwards at the level of supply orifices for transferring the hot liquid metal from the inner tank to the heat exchangers and wherein the cylindrical chambers are fixed directly onto the inner tank by neck portions interconnecting the two bulges and providing a path for liquid metal flow.
