  • Spacer
    Patent number: 7418072
    Abstract: A spacer for a fuel assembly for a light water nuclear reactor contains a plurality of intercrossed segments, which form a grid. The segments are formed from first and second metal strips which are assembled and provided with protruding parts or corrugations in such a way that the adjacent protruding parts are embodied in such a way that a flow component perpendicular to a vertical central plane which extends between the metal strips is applied to cold water running out from the flow sub-channel.
    Type: Grant
    Filed: May 12, 2005
    Date of Patent: August 26, 2008
    Assignee: Areva NP GmbH
    Inventors: Hans Kemner, Günter Bruch

  • Fuel assembly with a grid structure between the rods
    Patent number: 5402457
    Abstract: In a fuel assembly, rods are disposed in meshes of a grid. Crossing points of the grid are distributed in a checker-board-like manner, partly in an upstream crossing plane and partly in a downstream crossing plane. Webs of the grid run in zigzag form between the two planes. As a result, flow resistance which is produced by the webs and/or by mixing vanes disposed thereon and by flow turbulences is shifted into different axial planes and is considerably reduced.
