Passive safety device for emergency steam dump and heat removal for steam generators in nuclear power reactors
Creators
Description
This patent describes a pressurized water nuclear power reactor having at least one generator with a main feedwater line, a passive emergency steam dump comprising: a first storage for coolant water, the storage means having a drainage means to prevent excessive build-up of coolant water therein; a steam jet ejector disposed within the first storage means and immersed in the coolant water the steam jet ejector having an inlet and an outlet; means for feeding pressurized steam from the steam generator of a nuclear power reactor into the steam jet ejector; heat exchange means for cooling the hot condensate from the steam jet ejector, the heat exchange means having an inlet and an outlet, the inlet of the heat exchanger means being connected to the outlet of the steam jet ejector, and the outlet of the heat exchange means being connected to the first storage means; and a second storage means for coolant water in which the heat exchange means is immersed
