ABSTRACT:
An arrangement for the emergency cooling of the steam generator unit is of a pressurized-water nuclear power plant is disclosed. Steam is passed through a blow-off pipe (11) into a closed vessel (14) having a water space (12) and a gas space (13). A nest of heat exchanger tubes (15) extends through the water space (12) in a heat transfer relationship to cool the water space. Steam is dumped under emergency conditions into the vessel via a steam distributor nozzle (18) operatively connected at the end of the blow-off pipe and is condensed in the water space. The steam distributor nozzle is arranged essentially below and to the side of the nest of heat exchanger tubes to enhance mixing heat transfer. The resulting condensate is returned to the steam generator as condensate.
