摘要： A spacer grid for holding against lateral displacement a plurality of nuclear reactor fuel rods of heat exchange tubes includes means defining a plurality of side-by-side parallel compartments, each compartment being provided with a specially shaped arched spring plate which engages the fuel element or heat exchanger tube. The spring plates are so contoured and apertured as to provide passages for the flow of heat exchange fluid to thereby avoid stagnation of the fluid.
