摘要： Disclosed herein is a guide thimble of a nuclear fuel assembly, which is capable of improving the cooling performance and the stability of a nuclear fuel, preventing a flow split in dual-cooling nuclear fuel rod and guide thimble sub channels for obtaining high combustion degree and high power, and minimizing a neutron absorption section in a reaction degree region. Since the guide thimble having the dual tube type structure is adopted, a flow split in the fuel rod and guide thimble sub channels can be reduced, and the degradation in performance of nuclear fuel due to increase of a neutron absorption section can be prevented. In order for compatibility with an existing control rod, a typical guide tube is used as an inner guide thimble, and an outer guide thimble is provided outside the inner guide thimble. Thus, the guide thimble has the dual tube type structure as a whole, and is coupled to the upper and lower end fittings so that it can prevent a flow unbalance due to the flow split in the fuel rod and guide thimble sub channels.
摘要翻译：本文公开了一种核燃料组件的导向套管，其能够改善核燃料的冷却性能和稳定性，防止双冷核燃料棒和引导套管子通道中的分流以获得高燃烧度，高功率，并使反应程度区域中的中子吸收部分最小化。由于采用具有双管式结构的导向套管，因此可以减少燃料棒和导向套管副通道中的流动分流，并且可以防止由于中子吸收部分的增加而引起的核燃料性能的劣化。为了与现有的控制杆的兼容性，使用典型的导管作为内导向套管，并且外导向套管设置在内引导套管的外部。因此，导向套管作为整体具有双管式结构，并且联接到上端和下端配件，使得其可以防止由于燃料棒和引导套管子通道中的流动分流而导致的流量不平衡。
