    摘要: This describes a spacer for resiliently retaining the elongated fuel rods of a nuclear reactor in spaced relation. The spacer comprises a peripheral support band and dividers therein forming an "egg-crate" configuration of fuel rod passage from a corner thereof. The spacer is designed to minimize the contact area of the fuel rod with the spacer, to minimize distortion and restriction of coolant flow and to minimize the amount of spacer and retainer spring material. One embodiment is especially designed for fabrication from low neutron absorption material, such as Zirconium alloys and for the automated production thereof.
