Title: The Innovative Contributions of Alexander Steinke
Introduction
Alexander Steinke is a notable inventor based in Ebermannstadt, Germany. He has made significant contributions to the field of nuclear reactor technology, holding a total of 12 patents. His work focuses on enhancing the efficiency and safety of fuel assemblies in nuclear reactors.
Latest Patents
One of Steinke's latest patents is a spacer with specially fastened springs for fuel assemblies of nuclear reactors. This innovative spacer includes an elongated spring that is held in a mesh, allowing for structural freedom in the selection of the spring's shape while minimizing the amount of spring material required. The design features two lateral rims at the top end of the spring that are bent around the center of a fuel element, protruding through an assembly opening in the web into an adjacent mesh. This configuration enables the rims to approximately form-lockingly encompass the edge of the assembly opening using a profiled section. Additionally, the lower end of the spring is held on the web through profiled sections on its two outward-bent rims, allowing for two springs to protrude into adjacent meshes and be fastened in the same assembly opening.
Another significant patent by Steinke involves a fuel assembly with a grid structure between the rods. In this design, rods are arranged in meshes of a grid, with crossing points distributed in a checker-board-like manner across upstream and downstream crossing planes. The zigzag arrangement of the grid webs reduces flow resistance caused by the webs and mixing vanes, effectively shifting flow turbulences into different axial planes.
