Abstract
An end support system is applied to each end of a container for shipping nuclear fuel assemblies in an inner box within the container. The end support system includes a rectilinear metal end frame, a crosspiece with a reinforcing channel along an inside surface of the crosspiece and four arms projecting in a perpendicular direction from the metal end frame for straddling the sides of the container end. By screwing the metal end support system into the wooden framing elements of the container, the integrity of the container ends is maintained during hypothetical accident conditions specified in licensing regulations.
Claims16
An end support system for a container for shipping nuclear fuel, comprising:
- first and second elongated metal plates generally parallel to and spaced from one another and third and fourth metal plates generally parallel to and spaced from one another, said third plate being secured at opposite ends to ends of said first and second plates and said fourth plate being secured at opposite ends to opposite ends of said first and second plates thereby forming a generally rectilinear metal end frame;
- an elongated metal cross-plate secured at opposite ends to said third and fourth plates, respectively, at locations intermediate ends of said third and fourth plates, said cross-plate extending generally parallel to said first and second plates and lying generally in a plane defined by said metal end frame;
- a metal reinforcing member secured to said cross-plate and projecting from one side thereof and generally out of said plane, said member being located intermediate said opposite ends of said cross-plate and inwardly of said third and fourth plates;
- and
- at least a pair of metal supports connected to said metal end frame and extending generally perpendicular to said end frame along opposite sides of said metal end frame for securement to the sides of said container.

A container for shipping nuclear fuel, comprising:
- an elongated container body having sides, a top and bottom and opposite ends, a discrete metal and frame for reinforcing each of said opposite ends of said container body, each said metal end frame comprising first and second elongated metal plates generally parallel to and spaced from one another and third and fourth metal plates generally parallel to and spaced from one another, said third plate being secured at opposite ends to ends of said first and second plates and said fourth plate being secured at opposite ends to opposite ends of said first and second plates thereby forming said metal end frame in a generally rectilinear configuration;
- an elongated metal cross-plate secured at opposite ends to said third and fourth plates, respectively, and at locations intermediate ends of said third and fourth plates, said cross-plate extending generally parallel to said first and second plates and lying generally in a plane defined by said metal end frame;
- a metal reinforcing member secured to said cross-plate and projecting from one side thereof and generally out of said plane, said member being located intermediate said opposite ends of said cross-plate and inwardly of said third and fourth plates;
- at least a pair of supports connected to said metal end frame and extending generally perpendicular to said end frame along opposite sides of said metal end frame for securement to said container;
- said metal end frames being secured to said container body ends respectively, with said supports straddling opposite sides of said container body ends.

- an elongated container body having sides, a top and bottom and opposite ends;
- a metal end frame for overlying and reinforcing each of said opposite ends of said container body and lying in a plane, said ends and said sides of said container body being formed at least in part of wooden framing elements;
- a reinforcing member secured to said metal end frame and projecting from one side of said metal end frame and generally out of said plane, said member being located intermediate opposite edges of said metal end frame;
- at least a pair of metal supports connected to said metal end frame and extending generally perpendicular to said metal end frame along opposite sides of said metal end frame for securement to said container;
- each said metal end frame and said supports being secured to said wood framing elements along said ends and sides of said container body, respectively, with said supports straddling opposite sides of said container body ends, said reinforcing member engaging at least a portion of said container body to reinforce the container body.
