ABSTRACT:
A typical embodiment of the invention provides an efficient aid in positioning fuel elements in a nuclear reactor core. The corner edges of the peripheral band that binds the fuel element grid structure together, as well as the ends of the individual grid plates that protrude beyond the last marginal rows of fuel rods in each of the fuel elements are chamfered or bevelled. Thus, when fuel elements are being inserted, relocated or withdrawn from a reactor core the sloping edges of the grid structures in adjacent elements slide past without locking together or otherwise undesirably engaging each other.
