摘要： A storage-transport system includes a storage container and a transport container for respectively storing and transporting weak to intermediate level active nuclear waste. The storage-transport system has different containers for the functions of storage and transport, namely the storage container and the transport container. The storage container only meets the requirements for temporary storage which are less strict than the requirements for the transport container, thereby allowing for a simple and therefore less expensive construction of the storage container. A method for storing and for transporting radioactive waste is also provided.

摘要： A control rod drive contains a drive housing, in which a control rod carrying element is moveable between a basic position and an end position. The control rod carrying element is guided over a portion in a throttle bush. Formed across the throttle bush is a free flow cross section for a pressure fluid which varies in dependence on a position of the control rod carrying element. During an emergency shutdown, in which the control rod carrying element is moved hydraulically via a pressure fluid, the flow resistance for the pressure fluid is reduced, when the control rod carrying element reaches the end position. Therefore, a braking of the control rod carrying element takes place before it reaches the end position, thus reducing mechanical loads during braking. A flow resistance change takes place via a variable outside diameter of the control rod carrying element and/or by a bypass orifice.

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 assembly for a boiling water reactor has a plurality of fuel rods which are mounted in a plurality of spacers disposed at a spacing distance from each other in the axial direction of the fuel element. At least one of the fuel rods has a reduced length. Deflection elements are arranged at least in the upper region of the fuel element in order to improve the dry-out behavior of the assembly. The fuel assembly further includes measures that reduce a loss of pressure caused in the upper region by the deflecting elements so as to improve thermo-hydraulic stability and the shutdown behavior.

摘要： In a computer modeling method for the core of a nuclear reactor the core is divided into a plurality of primary grids in the form of coarse mesh cells. A sub-section of the core relating to at least one grid is assigned to that grid. The sub-section includes that grid and a buffer zone that surrounds the grid horizontally and contains at least the grid that lies immediately adjacent to the first grid. The sub-section is sub-divided into a plurality of secondary grids—fine mesh cells—that are smaller than the primary grids. In a first computing step, a model of the core is calculated using a nodal calculation method, based on a respective dataset that is assigned to each primary grid. In a second computing step, a respective second dataset is assigned to each secondary grid of a sub-section and a model is then calculated for the sub-section, based on the dataset and the flows on the border of the sub-section that have been calculated in the first computing step.
