<p>Fuel assembly for a nuclear reactor, preferably of PWR type, with a number of parallel fuel rods (2) which are held together by means of spacers (4, 5) arranged along the fuel rods as well as guide tubes (3) arranged between the fuel rods (2) in parallel therewith, said guide tubes (3) extending through the spacers (4, 5), and with a top nozzle (6) and a bottom nozzle (7) between which the guide tubes (3) are fixed. According to the invention bottom sleeves (8) for the guide tubes (3) are arranged in the spacer (5) nearest the bottom nozzle (7). The bottom sleeves (8) is rigidly fixed to said spacer (5) and rests against the bottom nozzle (7). The bottom sleeves (8) are provided with a first locking member for engaging in such a way with a second locking member, arranged at the end of a guide tube, that the the guide tube (3) is rigidly locked in the direction of rotation. <IMAGE></p> |
