ABSTRACT OF THE DISCLOSURE An arrangement for the emergency cooling of the steam generator unit of a pressurized-water nuclear power plant is disclosed. Steam 18 passed through a blow-off pipe (ll) 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 18 condensed in the water space. The steam distributor nozzle 18 arranged essentially below and to the side of the nest of heat exchanger tubes to enhance mixing heat transfer. The resulting condensate 18 returned to the steam gen- erator as condensate.
