摘要： The present invention relates to a spacer (7) comprising a plurality of cells (9) to retain and mutually fix, at a plurality of spacer levels, parallel, elongated elements (3, 8), extending through the cells, into a bundle in a fuel assembly for a nuclear reactor. A coolant is adapted to flow from below and upwards through the fuel assembly. Between the cells (9) of the spacer (7), secondary channels (10) are formed. The invention is characterized in that at least the majority of the spacer levels in the secondary channels (10) comprise at least two deflection members (14) which are axially spaced-apart in the direction of flow for guiding at least part of the coolant flow towards the fuel rods which are aranged close to the secondary channels (10).
摘要翻译：本发明涉及一种间隔物（7），其包括多个单元（9），以在多个间隔物水平上保持和相互固定平行延伸穿过细胞的细长元件（3,8）用于核反应堆的燃料组件。冷却剂适于从下方和上方流过燃料组件。在间隔件（7）的电池单元（9）之间形成第二通道（10）。本发明的特征在于，次级通道（10）中的至少大部分间隔物级包括至少两个偏转构件（14），其在流动方向上轴向间隔开，以引导冷却剂流的至少一部分朝向靠近次级通道（10）排列的燃料棒。

摘要： The present invention relates to a spacer in a fuel assembly and a fuel assembly. The spacer (7) is intended to retain, at a plurality of levels, longitudinal elements in a nuclear reactor and comprises an orthogonal latticework, surrounded by a sleeve-formed structure (10) arranged to extend both upstream and downstream of the orthogonal latticework. The invention is characterized in that the part of the structure (10) which extends upstream of the orthogonal latticework is arranged substantially at the corner portions of the orthogonal latticework, and in that the part of the structure (10) which extends downstream of the orthogonal latticework is arranged substantially along the sides of the orthogonal latticework.
摘要翻译：本发明涉及燃料组件和燃料组件中的间隔件。间隔件（7）旨在在多个水平面处保持核反应堆中的纵向元件，并且包括被布置成在正交网格的上游和下游延伸的套筒形结构（10）围绕的正交网格。本发明的特征在于，延伸到正交网格的上游的结构（10）的部分基本上布置在正交格子的角部，并且结构（10）的在正交网格的下游延伸的部分基本上沿着正交格子的边缘布置网格。
