摘要： A fuel rod or control rod for a nuclear reactor that has a spacer interposed between an upper end plug and a plenum spring which extends between the spacer and the fissile or absorber material. Preferably, the spacer is a relatively thin sleeve with a radially extending lip that sits above the coil spring wound at least in part around the sleeve.
