Perimeter strip for a nuclear reactor fuel assembly support grid
专利汇可以提供Perimeter strip for a nuclear reactor fuel assembly support grid专利检索，专利查询，专利分析的服务。并且A perimeter strip for a nuclear reactor fuel assembly support grid. The perimeter strip forms the outer edge of an egg-cratetype fuel-rod-spacing grid and is rigidly welded to the strips passing intermediate the fuel rods. It comprises a central portion parallel to the fuel rods and spaced therefrom as well as upper and lower portions parallel to the fuel rods at a location inwardly of the central portion. Sloping portions of the strip join the central portion and the upper and lower portions, with the distance between the outer surface of the outer fuel rods and the outer surface of the upper and lower portions being less than the distance between the outer surface of the central portion. The upper and lower portions are arched inwardly slightly to contact alternate fuel rods, while the and portion is formed to make resilient spring contact with the intermediate fuel rods. The sloped portion has holes therethrough adjacent the arches where rigid contact is made with the fuel rods. The egg crate structure is welded to the perimeter strip intermediate the arches and springs only at the upper and lower portions.，下面是Perimeter strip for a nuclear reactor fuel assembly support grid专利的具体信息内容。
