This patent describes a nonfuel burnable poison rod for use in a nuclear reactor, the nonfuel burnable poison rod comprising: (a) a tubular metallic cladding having upper and lower closure means. The lower closure means sealing the lower portion of the tubular cladding; (b) a neutron absorber in the form of an outer tube positioned concentrically within the tubular metallic cladding; (c) a neutron moderating spacing means for positioning the outer neutron absorber tube in spaced relation to the lower closure means. The neutron moderating spacing means being in the form of a solid cylindrical mass of a neutron moderating material; and (d) support means in the form of an inner metallic tube concentrically disposed within the outer neutron absorber tube and resting on the solid cylindrical mass of neutron moderating material.
