填充支承体位于主筒体内,其上端与主筒体径向配合,下端与重水箱下封头底座通过螺栓轴向固定,在反应堆寿期内,填充支承体为可更换部件。填充支承体为整体内多边形结构(图1),对燃料组件起定位支承。
The filling support body is located in the main cylinder body, the upper end of the filling support body is radially matched with the main cylinder body, the lower end of the filling support body is axially fixed with the lower sealing head base of the heavy water tank through bolts, and the filling support body is a replaceable component during the reactor life. The filling support is an overall inner polygon structure (FIG. 1) for positioning and supporting the fuel assembly.
