A nuclear reactor fuel assembly for accommodating mutually parallel rods disposed side by side therein includes a spacer formed of two mutually parallel grid sections having sides, each of the grid sections including outer straps flatly facing the rods at which the grid sections are interconnected, each of the grid sections including main sleeves being positioned like positions of the same color in rows and columns disposed at right angles to each other on a chess board leaving a free intermediate position between each two occupied positions, the main sleeves dividing the grid sections into grid mesh openings at the positions each able to receive a respective rod therein, each main sleeve in one of the grid sections having edges and being aligned with a main sleeve in the other grid section forming pairs of main sleeves, connecting straps each interconnecting the main sleeves of a pair of main sleeves forming contact springs for rods, each of the connecting straps having a width being smaller than the circumference of one of the main sleeves, and spacer sleeves each being disposed between two of the main sleeves in one of the grid sections, each of the spacer sleeves including two spacer sleeve parts disposed at corresponding sides of the grid sections, and each of the spacer sleeve parts being disposed at a respective edge of two of the main sleeves.
