摘要： Disclosed is a fuel element (2) for a pressurized water nuclear reactor, comprising a fuel element base (12) and a support structure for a plurality of fuel rods (4), which is mounted on said fuel element base (12). Cooling water (K) flows between the fuel rods (4) in an axial direction (3), said cooling water (K) flowing into the fuel element base (12) at a non-homogeneous axial speed distribution. A flow-directing structure is provided in the area of the fuel element base (12) for homogenizing the axial speed distribution of the cooling water (K) that enters between the fuel rods (4), thus reducing the risk of the fuel rods being subjected to flow-induced vibrations.

摘要： The core of a pressurized water reactor is assembled in such a way that if the fuel rods on the edge of the core bend, said bending is respectively oriented outwards in a convex manner. When the reactor is in operation, forces arise which increase the size of small gaps between said fuel rods at the expense of greater gaps and counteract the bending effect of said fuel rods.

摘要： The invention relates to a fuel element (4) for a pressurised water nuclear reactor. A plurality of fuel rods (10) extending in an axial direction are guided into a plurality of quadratic spacers (12) which are arranged at a distance from each other and are grid-shaped. The edge thereof is formed, respectively, by four edge web pieces (14a, b). At least one spacer (12) has at least two edge web pieces (14a, b) which are different from each other and which are used to produce a force (F) acting upon flowing cooling water (K) on the fuel element (4) on the plane of said spacer (12) in a transversal manner in relation to the axial direction. As a result, a systematic, predetermined deformation of a core (5), comprising said fuel elements, is produced and is taken into account in the configuration thereof .

摘要： The invention relates to storage racks (37, 39) for fuel elements in which hydraulic damping is achieved by the fact that the entire hydraulic diameter of one or more openings (5) in floor plates (3) of the shafts (1) of the fuel element storage rack has a value which corresponds to the hydraulic diameter of an imaginary opening having a diameter of between 8 % and 35 % of the external dimensions of the floor plate (3). The invention further relates to a fuel element storage rack (37, 39) which by way of a spring element (15) can be supported in a surrounding structure. The spring element (15) is preferably hydraulically damped. The preferably hydraulic damping of the fuel element storage racks (37, 39) provided for by the invention achieves an especially high resistance to an external influence, such as an earthquake or airplane crash. The hydraulically damped spring element (15; 60A, 60B, 60 C, 62A, 62B) can be supported notably vertically against the floor (29) of a fuel element storage pool (34) or horizontally against the wall (57) of the fuel element storage pool (34).
