    • A fuel assembly (1) for a boiling water nuclear reactor comprising a plurality of vertical fuel rods (3) which are arranged in spaced relationship between a bottom tie plate (6) and a top tie plate (5). The bottom tie plate (6) is provided with through-holes (6a) for the passage of a coolant (F). Further, the fuel assembly (1) comprises a bottom support (10) which is formed substantially from a downstream and an upstream flat surface (12, 13) and four side surfaces (14). The flat surfaces (12, 13) and the side surfaces (14) form a parallelepiped which surrounds a cavity. A filtering member is arranged in the upstream flat surface (13) and comprises a plurality of through-holes (11).
    • 一种用于沸水核反应堆的燃料组件(1),包括多个垂直燃料棒(3),它们在底板(6)和顶板(5)之间间隔设置。 底板(6)设置有用于冷却剂(F)通过的通孔(6a)。 此外,燃料组件(1)包括基本上由下游侧和上游平坦表面(12,13)和四个侧表面(14)形成的底部支撑件(10)。 平坦表面(12,13)和侧表面(14)形成围绕空腔的平行六面体。 过滤构件设置在上游平坦表面(13)中并且包括多个通孔(11)。

    • The invention refers to a filter (1) for separating particle from cooling water in a nuclear plant, and a fuel assembly with such a filter. The filter has an inlet end (2) and an outlet end (3) and permits through-flow of the cooling water in a main flow direction (x). The filter includes a number of sheets (4) extending in the flow direction from the inlet end to the outlet end. The sheets are arranged beside each other and form passages for the cooling water. The sheets include a first portion (4′) extending from the inlet end (2), a second portion (4″) extending from the outlet end (3), and a third portion (4′″) extending between the first portion (4′) and the second portion (4″). The sheets (4) have along the first portion continuous wave-shape extending in a direction (y) transversally to the flow direction (x) and along the third portion a continuous wave-shape extending in the flow direction (x).
    • 本发明涉及一种用于从核设备中的冷却水中分离颗粒的过滤器(1)和具有这种过滤器的燃料组件。 过滤器具有入口端(2)和出口端(3),并允许冷却水在主流动方向(x)上流过。 过滤器包括从入口端到出口端在流动方向上延伸的多个片材(4)。 这些片彼此相邻布置并形成冷却水的通道。 片材包括从入口端(2)延伸的第一部分(4'),从出口端(3)延伸的第二部分(4“)和在第一部分(4”)之间延伸的第三部分 部分(4')和第二部分(4“)。 片材(4)具有沿着沿流动方向(x)横向方向(y)延伸的第一部分连续波形,并沿着第三部分沿着流动方向(x)延伸的连续波形。
