Abstract
A gridlike spacer for fuel assemblies having rods in a bundle, includes polygonal grid meshes having ribs intersecting at corners and extending transversely to the rod bundle between the rods of the rod bundle. The ribs have lateral surfaces facing the rods penetrating the meshes. Springs each protrude diagonally into at least one corner of a respective one of at least a majority of the grid meshes. Each of the springs has a middle part for laterally supporting a given rod penetrating the respective mesh. The middle part is a cylinder segment curved convexly about an axis of curvature at right angles to the rod bundle. Each of the springs has two spring ends adjoining one another in the direction of the rod bundle. The middle part changes over at the spring ends with a convex curvature into two legs being approximately parallel to the rod bundle. The legs are supported at least on the lateral surface of one of the ribs facing toward the given rod.
