    • A fuel assembly for a pressurized-water reactor includes fuel rods held in cells of spacers, control rod guide tubes, and a headpiece and a foot piece, by which it is fixed to upper and lower core grids, respectively. A spacer having a first part, which lies on a radially outer side with respect to a longitudinal center axis of the fuel assembly, and a second part, which lies on a radially inner side and is completely surrounded by the first part are included to reduce the size of gaps between fuel assemblies. The second part is formed of Zircaloy. The first part is made of a metallic material, and when compared to the Zircaloy of the second part, has a lower growth in the radial direction, caused by neutron radiation and a higher coefficient of thermal expansion.
    • 用于加压水反应器的燃料组件包括保持在间隔件单元中的燃料棒,控制棒导向管以及头盔和脚踏板,分别固定在上部和下部芯网格上。 具有相对于燃料组件的纵向中心轴线位于径向外侧的第一部分和位于径向内侧并被第一部分完全包围的第二部分的间隔件被包括以减少 燃料组件之间的间隙的大小。 第二部分由Zircaloy组成。 第一部分由金属材料制成,与第二部分的Zircaloy相比,由中子辐射和较高的热膨胀系数引起的径向增长较小。

    • Hydraulic shock absorber, at least containing three concentrically arranged cylinder tubes, of which at least the radially exteriorly arranged cylinder tube is provided with an associated passage for receiving at least one module and the module is connected to the exterior cylinder tube via a fastening flange that is provided with a through-hole and that is at least partially supported on the exterior wall of the exterior cylinder tube, whereby provided concentric with the through-hole of the fastening flange is at least one largely cylindrical sleeve that forms a support surface for at least one sealing element that is held sealingly clamped at least between the outer surface area of the sleeve and the inner wall of the through-hole of the fastening flange that is arranged concentric with the surface area.
    • 液压减震器至少包含三个同心布置的气缸管,其至少径向外部布置的气缸管设置有用于接收至少一个模块的相关联的通道,并且该模块经由紧固凸缘连接到外部气缸管 设置有通孔,并且至少部分地支撑在外部气缸管的外壁上,由此与紧固凸缘的通孔同心地设置有至少一个大的圆柱形套筒,其形成用于 至少一个密封件被至少密封地夹紧在套筒的外表面区域和与表面区域同心设置的紧固凸缘的通孔的内壁之间。
