<p>Fuel assembly for a boiling nuclear reactor with at least one elongated channel, which is connected to a coolant intended to traverse the channel. A bundle of similarly elongated fuel rods, retained by a plurality of spacers (8), is arranged in the channel. The spacer (8) has an outer frame which is provided all around with a plurality of windows (10). According to the invention, deflection fins (9) are placed in said windows and are directed such as to divert cooling water flowing along the walls of the fuel channel in a direction towards the centre of the channel to improve the cooling for those fuel rods located in this region.</p> |
