The invention relates to a spacer of a combustion element for a light water nuclear reactor. The inventive spacer consists of a plurality of intercrossed segments (2) which form a grid. Said segments are consisted of a first and second metal strips (6,8) which are assembled and provided with protruding parts (10, 12, 14, 16) in such a way that the adjacent protruding parts (10, 14 and 12, 16) form respectively a flow subchannel (20). According to said invention, the adjacent protruding parts (10, 14 and 12, 16) are embodied in such a way that a flow component (vy) perpendicular to a vertical central plane (24) which extends between the metal strips (6, 8) is applied to the cold water running out from the flow subchannel. |
