Title: SPACER FOR A FUEL ASSEMBLY AND A FUEL ASSEMBLY
Abstract:
The present invention relates to a spacer (7) for a fuel assembly (1) and a fuel assembly (1) wherein the spacer (7) is intended to retain elongated elements (3, 8). The spacer (7) comprises a plurality of cells formed from a latticework of crossed first and second strip elements (9a, 9b) standing on edge, wherein those of the cells which are arranged equidistantly from the centre of the spacer (7) form a concentric cell segment of the latticework. The invention is characterized in that at least one of the concentric cell segments is arranged such that at least one part of a cell segment located radially outside is axially displaced in relation to a cell segment positioned inside such that the cell segment of the latticework with an increasing radius is subjected to a substantially continuous displacement in the axial direction of the elongated elements.
