ABSTRACT:
An improved pressure control system for a pressurized water nuclear reactor plant contains a novel, two stage sparger in the pressurizer relief tank. The two stage sparger has a primary conduit and secondary conduit, both of which have orifices through the walls thereof, and an interconnecting valve that is responsive to a pressure differential between the two conduits. The secondary conduit is preferably of a diameter less, but with a larger area of flow therefrom, than the primary conduit and is bifurcated, with two leg sections extending back towards the primary conduit.
