摘要： A fuel assembly for a pressurized water nuclear reactor includes a multiplicity of fuel rods which extend in a longitudinal direction and are guided in a plurality of spacers that are spaced apart from one another axially. The spacers of an upper region have a lower flow resistance in a transverse direction perpendicular to the longitudinal direction, than the spacers of a lower region.

摘要： A fuel assembly for a pressurized-water nuclear reactor contains a plurality of grid-shaped, square spacers spaced apart from one another. Each of the grid-shaped, square spacers has four edge webs. At least one of the spacers has at least two differently configured edge webs for generating a force which acts from a flowing cooling water on the fuel assembly in a plane of the spacer transversely with respect to an axial direction. A multiplicity of fuel rods extend in the axial direction and are guided in the plurality of grid-shaped, square spacers.

摘要： A fuel assembly for a pressurized water reactor has a plurality of fuel rods that are guided inside a plurality of axially spaced-apart spacers that are composed of grid webs. Each grid web forms a grid with a multitude of grid cells disposed in rows and columns. The grid webs are provided with flow guides for generating a cooling water current encompassing a transversal flow component that is oriented parallel to the spacer plane. At least one spacer is formed of a multitude of sub-regions, each of which is greater than one grid cell. The flow guides are configured and distributed within the spacer in such a way that in the wake above each sub-region, a transverse flow distribution is created which causes cooling water to be exchanged at least almost exclusively between secondary flow ducts located within the sub-region.

摘要： A fuel element for a pressurized water reactor has fuel rods guided through a number of axially spaced spacers. The spacers form a square grid with a multitude of mesh openings arranged in rows and columns. Support tubes that do not contain fuel are passed through a number of the mesh holes and are joined with a material bond to the meshes inside the spacer. The support tubes are spread out in positions within the grid in such a manner that, with a predetermined number of support tubes and a distribution thereof within the grid, which is rotationally symmetric about 90° with regard to a rotation about the central axis of the spacer, said central axis being perpendicular to the grid plane, the number of rows and columns that do not contain any support tubes is minimal. In addition, it is ensured that optionally remaining inner rows and columns that do not contain any support tubes are not situated next to one another.

摘要： A fuel assembly for a pressurized water nuclear reactor contains a multiplicity of fuel rods which are guided in a plurality of axially spaced spacers which in each case form a square grid, composed of grid webs, with a multiplicity of cells arranged in rows and columns. In each case one control rod guide tube is guided through a number of these cells. At least one spacer is configured to be mechanically stronger in a first partial region than in a second partial region. In this second partial region, the spacer is provided with at least one resisting element which protrudes into a flow sub-channel formed between the fuel rods and increases the flow resistance. The resisting element counteracts a reduction associated with the mechanically weaker configuration, in the flow resistance in the second partial region and in this manner effects a homogenization of the hydraulic behavior of a spacer which is mechanically inhomogeneous on account of the varying mechanical configuration.

摘要： A fuel assembly for a compressed water nuclear reactor contains a plurality of fuel rods that are guided into a plurality of axially interspaced spacers respectively forming a quadratic grid formed of connecting elements and containing a plurality of holes that are disposed in rows and columns. A control rod guiding tube is respectively guided through a number of the holes, and the spacer is structurally embodied in such a way that when a limiting force acting laterally on the spacer is exceeded, a deformation is triggered exclusively in a region of the spacer located outside an inner region containing the control rod guiding tubes.
