STEAM TURBINE NPP Russian patent published in 2016 - IPC F01K23/10 

FIELD: energy.

SUBSTANCE: invention relates to power engineering. Steam turbine nuclear power plant includes reactor plant steam generator connected to turbine consisting of high and low pressure cylinders installed on same shaft with electric generator, cylinders are connected to each other via steam pipeline, at which separator and two-staged steam-to-steam superheater are installed in steam flow direction, low-pressure cylinder is connected via steam pipeline with main condenser, which in its turn is connected by condensate line to deaerator, where condensate pumps are arranged in condensate flow direction, modular demineralizing plant, ejectors cooler and group of low pressure heaters. Deaerator is connected with reactor plant steam generator by makeup water pipeline, where makeup pump and group of high pressure heaters are installed in direction of water flow. Group of high pressure heaters is connected with high-pressure cylinder by steam extraction pipelines, and with two-staged steam-to-steam superheater is by steam superheater stages condensate lines. Deaerator is connected with high-pressure cylinder via steam extraction pipeline, to separator is by separator drain pipeline, with group of high pressure heaters is by high-pressure heater drain pipeline. Group of low pressure heaters is connected with low-pressure cylinder by steam extraction pipelines. Plant also includes satellite turbine connected with satellite turbine condenser and satellite turbine electric generator and start-up and redundant boiler room with pumps and control valves, which at inlet is connected with main condenser and with satellite turbine condenser, and at outlet is with low-pressure cylinder, with group of high pressure heaters and satellite turbine located on same shaft with satellite turbine electric generator.

EFFECT: invention enables to obtain additional power and maneuverability due to generation of additional steam and its supply to main turbine, due to creation of additional circuit containing satellite turbine with condenser and electric generator, also generating additional electric energy in peak period.
