Beschreibung
Zusammenfassung:	The method and system for bringing a nuclear power plant to a safe state after extreme effect reduce the temperature of the coolant after extreme effect. The system includes inlet and outlet pipelines (3, 9), a steam generator (1), a storage tank (8) and a heat exchanger (11), a separation tank (4) above the steam generator (1) and connected by two pipelines to a storage tank (8), a pump (10), a control unit. The method involves filling the system with coolant, feeding the coolant from the steam generator (1) through the inlet pipeline (3) and the storage tank (8) to the heat exchanger (11), and feeding the coolant through the outlet pipeline (9) back to the steam generator (1), wherein the pump (10) is turned on for feeding the coolant and subsequent operation of the system. The first air valve (7) is used to maintain pressure in the system, ensuring the absence of boiling of the coolant.
