Fast neutron reactor
Fast neutron nuclear reactor cooled by a liquid metal comprises a main vessel sealed by an upper slab and within said main vessel at least one heat exchanger between the said liquid metal and a second fluid, at least one pump for circulating the liquid metal. A cylindrical inner vessel with a vertical axis is placed on flooring resting on the bottom of the main vessel, the inner vessel containing the reactor core which rests on a support bearing against the bottom of the main vessel by means of the said flooring. The liquid metal circulates from bottom to top through the reactor core, wherein the said inner vessel incorporates an internal baffle which revolves about the vertical axis of the inner vessel, said baffle comprising an upper cylindrical part adjacent to the inner vessel and arranged above the core, and a lower cylindrical part surrounding the core and having a smaller diameter than the upper part, said lower part being connected to the upper part by a frustum-shaped part, whereby the baffle confines the ''hot'' liquid metal leaving the core. At least one pipe is arranged between the frustum-shaped part of the baffle and at least one heat exchanger connects the intake of the latter to the inner volume defined by the baffle.
