    • A spacer grid used for placing and supporting fuel rods in nuclear reactor fuel assemblies is disclosed. The spacer grid of this invention has a plurality of grid springs designed to have an optimal shape of their vertical support parts, thus reducing fretting wear of the fuel rods caused by contact of the fuel rods with the grid springs. The grid spring has a vertical support part and a fuel rod support part. The vertical support part includes upper and lower base parts extending downward and upward from the central portions of the top and bottom edges of an opening formed at the central portion of a unit strip, and two bridge parts branched from the upper base part and extending symmetrically downward until they are united at the lower base part. The fuel rod support part includes a conformal support part brought into surface contact with the external surface of a fuel rod. Two transverse connection parts extend outward from the opposite outside edges of the conformal support part while being specifically bent, and are integrated with the central portions of the inside edges of the two bridge parts into a single structure, thus connecting the fuel rod support part to the vertical support part.
    • 公开了用于在核反应堆燃料组件中放置和支撑燃料棒的隔离栅。 本发明的定位格栅具有多个格栅弹簧,其被设计成具有其竖直支撑部件的最佳形状,因此减少了燃料棒与格栅弹簧接触引起的燃料棒的微动磨损。 栅格弹簧具有垂直支撑部分和燃料棒支撑部分。 垂直支撑部分包括:上部和下部基部,从形成在单元条的中心部分处的开口的顶部边缘和底部边缘的中央部分向下和向上延伸;以及两个桥部,从上部基部分支并对称地延伸 向下,直到它们在下底部结合为止。 燃料棒支撑部件包括与燃料棒的外表面表面接触的共形支撑部件。 两个横向连接部分从共形支撑部分的相对外侧边缘向外延伸,同时特别弯曲,并且与两个桥接部分的内边缘的中央部分成一体结构,从而将燃料棒支撑部分连接到 垂直支撑部分。

    • PURPOSE: A double cooling cyclic type fuel rod and a manufacturing method thereof are provided to control compressive stress giving rise to the damage of an inner side zirconium alloy cladding tube by applying tensile stress to the inner side zirconium alloy cladding tube to an axial direction. CONSTITUTION: An inner side zirconium alloy cladding tube(1) is arranged on the same axel with an outer side zirconium alloy cladding tube(2). The diameter of the inner side zirconium alloy cladding tube is larger than the diameter of the outer side zirconium alloy cladding tube. A cyclic type UO2 sinter body(3) is offered between the inner side zirconium alloy cladding tube and the outer side zirconium alloy cladding tube. A cyclic type rod edge stopper(4) seals both ends of the inner side zirconium alloy cladding tube and the outer side zirconium alloy cladding tube. The inner side zirconium alloy cladding tube is composed of a complete recrystallization metal tissue. The outer side zirconium alloy cladding tube composed of one metal tissue selected from a group consisting of complete recrystallization, part recrystallization, and stress relaxation.
