A high-density fuel rack and system for wet storage of radioactive fuel, assemblies, such as spent nuclear fuel. The fuel rack includes a grid array of elongated cells each con figured for holding a fuel assembly, in one aspect, the cells are formed by a plurality of longitudinally- extending tubes having a rectilinear polygonal cross-sectional configuration. In one embodiment, the cells may have a cross-sectional shape of unequal width and length. The tubes may be variously arranged in contiguous or spaced apart configurations for non-flux trap and flux trap type racks, respectively. |
