Abstract
In APWR reactor coolant pump is both directly attached to steam generator channel head and elbow is eliminated. And nozzle dams are mounted on steam generator channel head outlet chamber. So the flow vector within steam generator channel head outlet nozzle is quite complex. Flow characteristics experimental study within connection between steam generator channel head and pump suction has been done by air test without nozzle dams and water loop test with them respectively. It is shown that axial vortex is eliminated and velocity is uniform in outlet section of outlet nozzle of steam generator channel head.
