Zusammenfassung:934,683. Reactors. NORTH AMERICAN AVIATION Inc. Nov. 25, 1960 [Nov. 27, 1959], No. 40552/60. Drawings to Specification. Class 39 (4). In a sodium-cooled graphite moderated reactor, the graphite is contained within a stainless steel vessel immersed in liquid sodium and having fuel element channels passing through it. The sodium is pumped vertically upwards in the channels and flows downwards round the vessel outer surface and over heatexchangers spaced around the vessel. An outer stainless steel tank contains the vessel, the sodium and the shielding surrounding the vessel. The rate of coolant flow through the fuel channels is controlled by a variable orifice and the temperature is increased by a thermocouple. Control rod channels are cooled by natural convection.
