    • The invention falls into the category of light-water reactor's designs, in which thorium is used as the fuel, especially the designs of 17×17 jacketless fuel assembly, from which the cores of water-cooled, water-moderated power reactors are formed, such as reactors of the PWR type (for example, the AP-1000, the EPR, etc.). The light-water reactor fuel assembly has a square shape in the plan view and contains a seed region, a blanket region that encircles it, a upper nozzle, a lower nozzle of seed region, and a lower nozzle of blanket region. The fuel elements' bundle of seed region is arranged in the rows and columns of a square coordinate grid and has a four-lobed profile that forms spiral spacer ribs along the length of a fuel element. The blanket region contains a frame structure within which a bundle of fuel elements made from thorium with the addition of enriched uranium is positioned. The blanket region fuel elements are arranged in the two rows and columns of a square coordinate grid. In the other embodiment of the invention, the light-water reactor fuel assembly has a similar design; here, the blanket region fuel elements are arranged in the three rows and columns of a square coordinate grid.
      The invention also falls into the category of the fuel elements employed in fuel assemblies and light-water reactors of the PWR type (for example, the AP-1000, EPR, etc.) that use fuel assemblies.
    • 本发明属于以钍为燃料的轻水反应堆设计,特别是17×17无夹套燃料组件的设计,其中形成水冷却,水慢化反应堆的核心, 例如PWR型反应堆(例如AP-1000,EPR等)。 轻水反应堆燃料组件在平面图中具有正方形形状,并且包含种子区域,环绕它的毯子区域,上部喷嘴,种子区域的下部喷嘴和毯子区域的下部喷嘴。 种子区域的燃料元件束被布置在正方形坐标网格的行和列中,并且具有沿着燃料元件的长度形成螺旋间隔肋的四叶形轮廓。 橡皮布区域包括框架结构,在该框架结构中,定位由钍制成的燃料元件束,并添加浓缩铀。 橡皮布区域燃料元件布置在正方形坐标网格的两行和列中。 在本发明的另一实施例中,轻水反应堆燃料组件具有相似的设计; 这里,橡皮布区域燃料元件布置在正方形坐标网格的三行和列中。 本发明还属于使用燃料组件的燃料组件和使用燃料组件的PWR型(例如,AP-1000,EPR等)的轻水反应堆的类别。
