FIELD: power industry.
SUBSTANCE: nuclear power station comprises the reactor housing with the central and peripheral parts; the shaft with active zone located in the central part of the housing; the liquid metal heat carrier, the circulation pump, the steam generator placed in peripheral part of the housing; the cavity with protective gas located above the heat carrier, the protective gas injection device. The device is located in the peripheral part of the housing above the upper cut of the steam generator in the zone of suction of the circulation pump containing the intake and working parts. The intake part is located in the named cavity with protective gas and has holes in the upper part, and the working part - under the free level of the liquid metal heat carrier.
EFFECT: formation of stable gas-liquid mix with the required dispersion of gas bubbles.
