Liquid metal cooled nuclear reactors with passive cooling system
This patent describes a passive cooling system for liquid metal cooled nuclear reactors. It consists of the combination of a reactor vessel enclosing a heat generating core and assembly containing fissionable fuel surrounded by a spaced apart encircling fuel core assembly support cylinder provided with an upper and a lower inward projecting flange for securing the fuel core assembly within the reactor vessel, a primary heat exchanger cylinder positioned concentrically intermediate the fuel core assembly support cylinder and the fuel core assembly in spaced apart relation with each the support cylinder and the fuel core assembly, the reactor vessel being substantially filled with liquid metal coolant whereby the fuel core assembly is submerged therein, the fuel core assembly having a multiplicity of vertical coolant passages extending through the axial length thereof providing for a primary heat exchanging convection circuit for the liquid metal coolant passing upward through the heat producing fuel core to an area above the fuel core assembly and returning around down through a space between the fuel core assembly and the primary heat exchanger cylinder for recycling around and up through the fuel core assembly.
