    Abstract: PURPOSE: To obtain a grid having easy industrial production and mechanically isotropic structure irrespective of three sets of plates. CONSTITUTION: The grid 13 for fuel assembly of a nuclear reactor comprises a belt 40 having a hexagonal shape, and three sets of plates 44, 46, 48 having ends fixed to the belt 40. The plates of the sets of the plates are parallel to each other, and disposed so that the plates of the two sets cross at the angle of 120 deg. All the plates of the same set have the same length, have an angle of 120 deg., and further parallel to only the two continuous surfaces of the belt.
