The fuel rods (11), which are combined to form a bundle, have longitudinally finned sheaths (12) which contain the fuel. The continuous or interrupted fins of these rods are brazed either with fins of adjacent rods or directly to these rods (or both). The unit of rods soldered together can be used to fulfil the thermal and hydraulic requirements of a fuel unit whose moderator to fuel atomic ratios produce high conversion and breeding ratios. <IMAGE> |
