Abstract
A storage rack for spent nuclear fuel rods is provided having multiple parallel tubes of polygon cross-section with their confronting surfaces having embossed buttons in engagement and having at least one pad of neutron poison material interposed between the confronting surfaces. The tube cells are secured together such that the neutron poison material effectively establishes each individual cell as a neutron isolation chamber and further functions to dampen mechanical vibrations which may be applied to the assembled storage rack.
