Abstract
A fast reactor of the sodium-cooled type comprises a vertical main vessel for supporting the reactor core and an internal primary vessel for separating the hot sodium discharged from the reactor core from the cold sodium discharged from the heat exchangers. The primary vessel essentially has a shape of revolution about the vertical axis of the main vessel and is provided with a lateral skew section traversed by the heat exchangers and the sodium pumps. A turned-down edge located at the exterior of the primary vessel and forming an extension of the skew section is joined to the main vessel at the lower end.
Claims5
A fast reactor cooled by liquid sodium comprising a main reactor vessel having a vertical axis a reactor core supported by said main vessel, a primary vessel within said main vessel and containing said reactor core, said primary vessel separating hot liquid sodium discharged from said reactor core and cold liquid sodium, heat exchangers within said main reactor vessel, pumps circulating the cold liquid sodium discharged from said heat exchangers to said reactor core, an annular lateral skew section for said primary vessel, openings through said section receiving said heat exchangers and said pumps, said primary vessel having a shape of revolution about the vertical axis of said main vessel, a turned down edge for said skew section at the exterior of said primary vessel and means joining said turned down edge to said main vessel at a lower extremity of said edge, outlets of said heat exchangers being adjacent the lower surface of said skew section.
A fast reactor cooled by liquid sodium comprising a main reactor vessel having a vertical axis, a reactor core supported by said main vessel, a primary vessel within said main vessel and containing said reactor core, said primary vessel separating hot liquid sodium discharged from said reactor core and cold liquid sodium, heat exchangers within said main reactor vessel, pumps circulating the cold liquid sodium discharged from said heat exchangers to said reactor core, an annular lateral skew section for said primary vessel, openings through said section receiving said heat exchangers and said pumps, said primary vessel having a shape of revolution about the vertical axis of said main vessel, a turned down edge for said skew section at the exterior of said primary vessel, at least one baffle-plate element and one counter-baffle-plate element for said main vessel which define with said vessel wall an annular space for circulating a flow of cold liquid sodium, and means joining said turned down edge of said skew section of said primary vessel to said counter-baffle-plate element.
