Section: claims

1. A fuel assembly, comprising: a bundle of fuel rods;  approximately mutually parallel upright webs extending between said fuel rods in a plane approximately perpendicular to said fuel rods;  said webs having upper edges and tabs on said upper edges, each of said tabs having an end, and each of said tabs being twisted toward said end about an axis approximately parallel to said fuel rods; and  said tabs tapering continuously up to a twisting of 45.degree. relative to said webs.  a bundle of fuel rods;  approximately mutually parallel upright webs extending between said fuel rods in a plane approximately perpendicular to said fuel rods;  said webs having upper edges and tabs on said upper edges, each of said tabs having an end, and each of said tabs being twisted toward said end about an axis approximately parallel to said fuel rods; and  crosswise webs joining said ends of said tabs of adjacent webs to one another, said tabs having tab parts being twisted by 90.degree. relative to said webs, and said tab parts merging with said crosswise webs.  a bundle of fuel rods;  approximately mutually parallel upright webs extending between said fuel rods in a plane approximately perpendicular to said fuel rods;  said webs having upper edges and tabs on said upper edges, each of said tabs having an end, and each of said tabs being twisted toward said end about an axis approximately parallel to said fuel rods;  one of said webs having a part extending between two of said fuel rods with two protrusions formed from said web, one of said two fuel rods being supported on said protrusions; and  a spring on which the other of said two fuel rods is supported. 2. The fuel assembly according to claim 1, including crosswise webs joining said ends of said tabs of adjacent webs of one another, said tabs having tab parts being twisted by 90.degree. relative to said webs, and said tab parts merging with said crosswise webs. 3. The fuel assembly according to claim 1, wherein said tab parts of said tabs of adjacent webs have formed-on web parts, and said crosswise webs are formed by welding said web parts together. 4. The fuel assembly according to claim 1, wherein one of said webs has a part extending between two of said fuel rods with two protrusions formed from said web, one of said two fuel rods is supported on said protrusions, and including a spring on which the other of said two fuel rods is supported. 5. The fuel assembly according to claim 1, wherein said fuel rods are disposed in square holes in a grid having intersections, said tabs are disposed at least at some of the intersections, and said tabs at two adjacent intersections carrying said tabs are twisted in mirror fashion relative to one another. 6. The fuel assembly according to claim 1, wherein said tabs have a width being dependent on a spacing from said upper edges of said tabs. 7. A fuel assembly, comprising: 8. The fuel assembly according to claim 7, wherein said tab parts of said tabs of adjacent webs have formed-on web parts, and said crosswise webs are formed by welding said web parts together. 9. A fuel assembly, comprising:
