摘要： A radioactive debris trap to be installed in a steam generator for removing debris in the primary flow of a nuclear power plant's primary heat transport system. The debris trap includes an outer cylinder and a coaxial inner cylinder both having a top end and a bottom end. A top plate connects the top ends of the outer and inner cylinders. A bottom plate which encloses the trap is connected to the bottom end of the outer cylinder. There is a gap between the bottom end of the inner cylinder and the bottom plate through which primary flow enters a settling chamber located in an annular gap between the outer and inner cylinders. Several small holes are located at the top end of the outer cylinder through which liquid exits the debris trap. A means for fixedly connecting the debris trap to the steam generator is provided on the outer surface of the outer cylinder. Also included is a means for removing the radioactive debris trap from the steam generator without exposing personnel to excessive radiation.

摘要翻译： 要安装在蒸汽发生器中的放射性碎片陷阱，用于清除核电厂主要热交换系统主流中的碎屑。 碎片捕集器包括外筒和同轴的内筒，两者都具有顶端和底端。 顶板连接外筒和内筒的顶端。 封闭收集器的底板连接到外筒的底端。 在内筒的底端和底板之间存在间隙，主流通过该间隙进入位于外筒和内筒之间的环形间隙中的沉降室。 外筒的顶端有几个小孔，液体通过该小孔离开碎屑陷阱。 在外筒的外表面上设置有用于将碎屑捕获器固定地连接到蒸汽发生器的装置。 还包括用于从蒸汽发生器中除去放射性碎片捕集器的手段，而不会使人员过度辐射。
