在一些实施例中，第一管1包括第一段和第二段，第一段的在储球罐5宽度上的横截面积小于第二段在储球罐5宽度上的横截面积。
具体地，第一段的下端与第二段的上端相连，第一段在左右方向上的横截面小于第二段在左右方向上的横截面，通过第一段在左右方向上的横截面小于第二段在左右方向上的横截面，可以降低核反应堆运行时通过第二管2传递的核辐射，或者，降低核辐射物质通过第二管2逸散，进而提高吸收球停堆装置的稳定性和安全性。可选地，第一段可以为实心管，第二段可以为中空管，第一段与第二段一体成型。
可选地，第一管1和第二管2之间设有预设间隙，即第一管1与第二管2之间具有间隙，预设间隙大小小于吸收球的直径以避免吸收球落入预设间隙，且预设间隙还降低核辐射及核辐射物质扩散的风险，进而提高吸收球停堆装置的稳定性和安全性。
