1. A fuel rack for storing spent nuclear fuel comprising:
a baseplate; and
a cellular body coupled to the baseplate and comprising a plurality of open cells, each cell having a hexagonal configuration to receive a fuel assembly therein, each cell being formed by a plurality of angled cell walls and corners formed between adjoining cell walls;
wherein the cells are arranged so that the corners of each cell directly abuttingly engage only the corners of any adjacent cell of the cellular body so as to define a triangular flux trap on each side of the directly abuttingly engaged corners.
