    • A method of storing a chimney assembly of a reactor pressure vessel during a nuclear reactor outage may include detaching a chimney barrel with upper chimney partitions therein from a top guide assembly of the reactor pressure vessel. A height of the upper chimney partitions is less than a height of the chimney barrel so as to leave a plenum region in a top section of the chimney barrel. The top guide assembly includes lower chimney partitions therein. The lower chimney partitions are removed from the top guide assembly and inserted into the plenum region of the chimney barrel so as to be on the upper chimney partitions. As a result, the chimney assembly can be stored in a relatively compact form during a reactor outage. The chimney assembly may be a combination of at least the chimney barrel, the upper chimney partitions, and the lower chimney partitions.
    • 在核反应堆中断期间存储反应堆压力容器的烟囱组件的方法可以包括从反应堆压力容器的顶部引导组件将具有上部烟囱分隔件的烟囱筒分离。 上烟囱隔板的高度小于烟囱筒的高度,以便在烟囱筒的顶部部分中留下增压室。 顶部导向组件包括其中的下部烟囱分隔件。 下部烟囱分隔件从顶部引导组件移除并插入到烟囱筒的增压室区域中,以便在上部烟囱分隔壁上。 结果,烟囱组件可以在反应堆中断期间以相对紧凑的形式存储。 烟囱组件可以是至少烟囱筒,上部烟囱分隔件和下部烟囱分隔件的组合。
