1. Fuel assembly for a nuclear reactor with a plurality of parallel fuel rods (1), which are retained by means of spacers (2) arranged along the vertical extension of the fuel rods (1), with guide tubes (3) arranged between the fuel rods (1), the guide tubes (3) being fixed to the spacers (2), and with a top nozzle (4) and a bottom nozzle (5) between which the guide tubes (3) with the associated fuel rods (1) are fixed. According to the invention the guide tubes (3), at least at the spacers (2), are provided with external threads (7) adapted to engage with corresponding threads provided at the spacers (2) to fix these to the guide tubes (3). <IMAGE> |
