NUCLEAR FUEL ASSEMBLY SPACER GRID AND CORRESPONDING NUCLEAR FUEL ASSEMBLY

摘要

The nuclear fuel assembly spacer grid (8) defines a lattice of cells (16) for receiving fuel rods (4). The spacer grid (8) comprises a peripheral band (11) composed of at least one peripheral strip (12) delimiting a portion of the peripheral contour of the spacer grid (8), and at least one spacer grid positioning spring (22) elastically deformable and formed in the peripheral band (11).
