Eccentric support grid for nuclear fuel assembly

A nuclear reactor fuel assembly structured to support at least one non-linear fuel rod, said nuclear reactor fuel assembly comprising:

• a bottom nozzle;
• a plurality of thimbles extending upwardly from said bottom nozzle;
• at least two support grids, a first support grid and a second support grid, coupled to said thimbles, said at least two support grids structured to support said at least one non-linear fuel rod;
• said at least two support grids each comprising a plurality of generally square cells and wherein the cells on said first support grid and said second support grid are generally vertically aligned;
• each said cell having a first side, a second side, a third side, a fourth side, with protrusions extending from each said cell side, and wherein said protrusions are selected from a group including a spring, a dimple or an extended dimple, with a spring always disposed opposite of a dimple or an extended dimple;
• said first support grid includes at least one cell having an extended dimple extending from at least one cell side;
• said second support grid includes at least one cell aligned with said first support grid at least one cell having an extended dimple, wherein said second support grid cell has an extended dimple extending from a cell side not aligned with said cell side having an extended dimple on said first support grid;
• and
• wherein said extended dimples cause said fuel rod to be deformed.
