FIELD: atomic power engineering.
SUBSTANCE: invention relates to nuclear power engineering. System of passive heat removal of nuclear reactor includes heat exchanger arranged in air flow in air exhaust channel and connected to source of excessive heat energy of object, for example steam generator of NPP. In addition, there is a heat drive sensor with a retracting power rod, a cylinder with high pressure gas, a reservoir with liquid and two-phase nozzles. Heat drive sensor is arranged on heat exchanger. Drive rod is connected to valve of gas cylinder. Outlets from the gas cylinder and from the liquid reservoir are connected through pipelines and valves to the inputs of two-phase nozzles, at that the nozzles are installed with the direction of their output flow to the heat exchanger.
EFFECT: invention allows simplifying the system design and improving efficiency of heat energy removal from the heat exchanger located in the air flow, the exhaust channel of the object.
