Abstract

一种下管座(100)及轻水反应堆燃料组件，该下管座(100)包括围板(10)、连接柱(20)、横向薄条(30)及纵向薄条(40)，围板(10)呈贯穿的中空结构且底部具有向下凸伸的支腿(11)，中空结构形成空腔，横向薄条(30)设置于空腔中，纵向薄条(40)设置于空腔中，横向薄条(30)与纵向薄条(40)均与围板(10)固定连接，横向薄条(30)与纵向薄条(40)在水平面的投影相交并形成交错的网格状，连接柱(20)贯穿横向薄条(30)及纵向薄条(40)并与被所贯穿的横向薄条(30)与纵向薄条(40)固定；由于横向薄条(30)与纵向薄条(40)在水平面的投影相交并形成交错的网格状，使得整个下管座(100)形成立体式的网格状水流通道，从而提高了过滤能力且使水流压降小。
