OSTI ID:4095215
A fuel-element assembly was designed for gas-cooled graphite-moderated reactors. The assembly consists of a finned fuel element seated in a sleeve with a space in between for coolant flow. The advantages of this elementsleeve design are avoidance of element damage during handling, avoidance of major contamination of the reactor moderator in case of element rupture, simplified element support problems. and flexibility of element design. The internal diameter of the sleeves is tapered from bottom to top so that coolant flow increases going upward, resulting in operation of the fuel elements in one channel at the same temperature. The taper is aiso varied with the channel position in the core so that greater cooling occurs in the core center. (D.L.C.)
