Nuclear fuel assembly

A nuclear fuel assembly comprises a cluster of elongated fuel, retained parallel and at the nodal points of a square network by a bottom supporting plate and by spacing grids. The supporting plate is connected to a top end plate via tie-rods which replace fuel pins at certain of the nodal points of the netword. The diameter of the tie-rods is equal to that of the pins and both are slidably received in the grids.
