Nuclear fuel assembly spacer grid and corresponding nuclear fuel assembly

A nuclear fuel assembly spacer grid defining cells for receiving fuel rods, the spacer grid comprising:

• a peripheral band composed of at least one peripheral strip delimiting a portion of the peripheral contour of the spacer grid, and at least one spacer grid positioning spring elastically deformable and formed in the peripheral band;
• and
• interlaced intermediate strips distributed within the peripheral contour,
• the at least one spacer grid positioning spring protruding outwardly relative to the at least one peripheral strip,
• the at least one spacer grid positioning spring being cantilevered by extending in a cantilever fashion horizontally away from or towards a corner of the spacer grid,
• the at least one spacer grid positioning spring including a flexible cantilever tab and a contact portion protruding outwardly from the flexible cantilever tab,
• the at least one spacer grid positioning spring being located vertically between an upper plane and a lower plane of the spacer grid, the upper plane being defined respectively by upper edges of the interlaced intermediate strips, the lower plane being defined by lower edges of the interlaced intermediate strips of the spacer grid.
