摘要： An apparatus in a steam generator that employs tube support plates within a shroud that is in turn disposed within a shell. The tube support plates are made of a material having a coefficient of thermal expansion lower than that of the shroud. The tube support plates are aligned during fabrication with minimal clearances between components. Using a tube support displacement system, a controlled misalignment is imposed on one or more tube support plates as the steam generator heats up. The tube support plate displacement system has only two parts, a spring bar and a push rod, that are internal to the steam generator shell and threadably engaged, thereby minimizing the potential of loose parts. The tube support plate displacement system can be used to provide controlled misalignments on one or more tube support plates, with one or more apparatus being provided for any individual tube support plate.

摘要： A self-supporting system for positioning and restraining the U-bend tubes in the U-bend region of a nuclear steam generator includes arrays incorporating unique support bars having nubs projecting in the out-of-plane direction of the tube planes. The system also includes assemblies for spacing the arrays, tie bars to prevent the arrays from splaying and saddle bar assemblies to support the outermost tube layers. The system provides positive restraint to nub engaged tubes in both the in-plane direction of the tube planes and the out-of-plane direction.

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.
