1. 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. 2. A system according to  claim 1  wherein said reinforcing member and said supports project in the same direction from the plane of said metal end frame. claim 1 3. A system according to  claim 1  wherein said reinforcing member is elongated and extends along a central region of said crosspiece, terminating at opposite ends short of the ends of said crosspiece. claim 1 4. A system according to  claim 3  wherein said reinforcing member comprises a channel. claim 3 5. A system according to  claim 1  wherein said metal supports comprise a pair thereof secured to each of opposite sides of said metal end frame. claim 1 6. A system according to  claim 1  wherein said metal supports comprise four arms secured to said end frame adjacent corners thereof. claim 1 7. 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. 8. A container according to  claim 7  wherein said ends and said sides of said container body are formed at least in part of wooden framing elements, each said metal end frame and said supports thereof being secured to said wooden framing elements along said ends and said sides, respectively, of said container body. claim 7 9. A container according to  claim 7  wherein each said container body end includes wooden framing elements underlying said metal plates, respectively, and in a plane parallel to said plane of said end frames, said reinforcing member extending between a pair of said wooden frame elements. claim 7 10. A container according to  claim 7  wherein each said container body end includes wooden end framing elements forming a wooden end frame underlying said metal end plates, respectively, and in a plane parallel to said plane of said metal end frame, an end panel on each said container body end secured to a side of said wooden end framing elements opposite said metal end frame, said reinforcing member projecting from the plane of said metal end frame to reinforce said end panel. claim 7 11. A container according to  claim 10  wherein said reinforcing member extends between a pair of said wooden frame elements of said wooden end frame and comprises a channel. claim 10 12. A container according to  claim 7  wherein said metal supports comprise four arms secured to said end frame adjacent corners thereof. claim 7 13. A container for shipping nuclear fuel, comprising: 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. 14. A container according to  claim 13  wherein said metal end of frames are discrete and spaced from one another at said opposite ends of said container body, said container body including wooden end framing elements forming wooden end frames underlying said metal end plates, respectively, said wooden end frames lying in planes parallel to planes containing said metal end frames, an end panel on each said container body end secured to a side of said wooden end framing elements opposite said metal end frame, said reinforcing member projecting form the plane of said metal end frame to reinforce said end panel. claim 13 15. A container according to  claim 14  wherein said reinforcing member extends between a pair of said wooden end frame elements and comprises a channel. claim 14 16. A container according to  claim 15  wherein said metal supports comprise four arms secured to said end frame adjacent corners thereof. claim 15
