ABSTRACT:
A loose parts collection weir that is a nearly cylindrical structure that is integrally attached to the lower deck plate or sludge collector top plate of a steam generator to retain loose parts along the feedwater and recirculation water transit path to the tube bundle. The weir is a near vertical structure built into the upper drum of the steam generator, near the periphery of the lower deck plate or sludge collector top plate in the vicinity of the downcomer annulus. The weir may contain a radially inwardly projecting lip which forms a pocket for loose parts to collect. As the feedwater flows toward the downcomer annulus, loose parts will tend to deposit onto the lower deck plate aided by gravity and be trapped by the loose parts collection weir.
