Abstract
A spacer for a nuclear reactor fuel assembly includes sheet metal webs which intersect one another on edge and form grid meshes. A leaf spring projects from a sheet metal web in a grid mesh and is assigned to a bearing boss for the force-locking holding of a rod in the grid mesh. The leaf spring is attached to the sheet metal web at a leaf edge extending in the longitudinal direction of the rod. In order to avoid fretting in a nuclear reactor, a perforation is formed in the leaf spring and has a contour that narrows toward the sheet metal web to which the leaf spring is attached.
