ABSTRACT:
A ventilating system for an enclosure in a nuclear power plant is provided. The enclosure houses an emergency feedwater pump and its driver steam turbine. An eductor mounted in the enclosure is supplied with steam exhausting from the driver steam turbine. The steam jet formed by the eductor draw hot air out of the enclosure, thereby preventing the excessive build-up of heat in the enclousre. An air inlet formed in another wall of the enclosure supplies the enclosure with cool ambient air. The eductor and air inlet are situated to ensure the incoming air flows over the pump, thereby cooling it. A duct transports the steam/air mixture discharged by the eductor to the atmosphere.
