摘要： A spacer grid with an unsymmetrical dimple for filtering a debris is provided to minimize a cross section in a horizontal direction and to reduce a maximum diameter for inflow of the debris through an effective cross section structure of the dimple. A spacer grid with an unsymmetrical dimple for filtering a debris(D) includes a spacer grid(20) and a dimple(21). The spacer grid divides a plurality of unit grid cells by crossing strips with slots horizontally and vertically and reciprocally inserting the slots. The dimple is formed by asymmetrically bending the strips to be divided into a short piece(212) and a long piece(211), projected from centers of grid surfaces of the spacer grids in a perpendicular direction, and installed on the grid surface in a direction to have a minimum cross section for an axial direction of the spacer grid to support a lower rod short stopper(14) of a fuel rod through a line contact between the long piece of the dimple and the lower rod short stopper.

摘要： A top nozzle assembly having a volute spring in a nuclear fuel assembly is provided to secure rigidity against an external stress and endure load by a hydraulic uplift force of the nuclear fuel assembly when reducing a close adhesion length of the spring. A top nozzle assembly for a nuclear fuel assembly includes a press plate(25), a passage plate(24), a volute spring, and a peripheral guide pillar(22). The press plate includes a circular press plate central penetration hole(251) and four circular press plate peripheral penetration holes(252) and is supported by an insertion pipe of a nuclear reactor. The passage plate includes a circular passage plate penetration hole(241) and four passage plate peripheral penetration holes(242). A guide pipe and a measurement pipe of the nuclear fuel assembly are connected to the passage plate peripheral penetration holes and the passage plate central penetration hole respectively. The volute spring is supported by being connected to the press plate peripheral penetration holes and limits the motion of the nuclear fuel assembly in an axial direction transmitted to the passage plate by being connected to the passage plate peripheral through holes. The peripheral guide pillar is formed in a hollow cylinder shape, includes a peripheral suspension unit(221) which is formed on an upper part and has a greater diameter than that of a body, and limits the motion of the passage plate in a horizontal direction by being fixed to the passage plate peripheral penetration holes through the press plate peripheral penetration holes and a center of the volute spring.

摘要： A top nozzle assembly having a double hold down spring in a nuclear fuel assembly is provided to stably fix a position of the nuclear fuel assembly and prevent the nuclear fuel assembly from being bent by providing a proper pushing force for a length change of the nuclear fuel assembly. A top nozzle assembly having a double hold down spring in a nuclear fuel assembly includes a pushing plate(11), an outer guide post(12), a supporting unit(10), a central guide post(14), and an elastic body(20). The elastic body has a spring which provides an elastic force to the nuclear fuel assembly. The outer guide post is vertically connected between the pushing plate and a flow field plate. The central guide post is vertically protruded to the flow field plate in parallel with the outer guide post in the pushing plate direction. The elastic body has first and second springs which have different elastic coefficient and are penetrated by the outer guide post. The first and second springs are connected to each other in series. A plate is installed between the first spring and the second spring of the elastic body.
