ABSTRACT OF THE DISCLOSURE The invention provides a fuel assembly spacer for a nuclear reactor; the spacer having a plurality of springs with uniform spring strength and arranged symmetrically around the outer periphery of the spacer so that the fuel assembly can be coaxially disposed with respect to a coolant duct. This spacer serves to maintain uniform a gap as possible between the inner wall of the coolant duct and each outermost fuel rod in the fuel assembly so that the flow of the coolant keeps its symmetry in the section of the coolant duct, thereby improving the thermal performance of the fuel assembly.
