    • PROBLEM TO BE SOLVED: To provide a fuel rod and a fuel assembly capable of making thermal output uniform over an axial direction and elongating operation cycle.SOLUTION: A first fuel rod 41 and a second fuel rod 42 are loaded in a pressurized-water reactor, and contain a nuclear fuel and a burnable poison such as gadolinium which reduces the nuclear reaction of the nuclear fuel. The content rate of gadolinium increases from both sides of the axial direction of the first fuel rod 41 and the second fuel rod 42 toward an axial center. In a fuel assembly, in which the first fuel rod 41 and the second fuel rod 42 are provided, the fuel rods are loaded in such a manner that a rate that the second fuel rods 42 of low-gadolinium are arranged more outside than the first fuel rods 41 of high-gadolinium is high.
    • 要解决的问题:提供一种能够在轴向上使热输出均匀并且延长操作循环的燃料棒和燃料组件。 解决方案:第一燃料棒41和第二燃料棒42装载在加压水反应器中,并含有核燃料和诸如钆的可燃毒物,这减少了核燃料的核反应。 钆的含有率从第一燃料棒41和第二燃料棒42的轴向的两侧向轴向中心增加。 在其中设置有第一燃料棒41和第二燃料棒42的燃料组件中,燃料棒的加载速度使得低钆的第二燃料棒42比第一燃料棒 高钆燃料棒41高。 版权所有(C)2012,JPO&INPIT
