HYBRID NUCLEAR POWER PLANT Russian patent published in 2025 - IPC G21D5/14 

FIELD: nuclear power plant.

SUBSTANCE: invention relates to development of hybrid nuclear power plants with high operational manoeuvrability. Hybrid nuclear power plant comprises a steam generator, valves, a high-pressure cylinder (HPC) of a wet-steam turbine, a separator, a steam-steam superheater, low-pressure cylinder of a wet-steam turbine, an electric generator of a wet-steam turbine, a condenser, a condensate pump, a chemical water treatment system, low pressure regenerative heater system, deaerator, feed pump, feed pump turbo drive, system of regenerative high-pressure heaters, remote superheater, HPC of high-temperature turbine with back pressure, electric generator of high-temperature turbine with back pressure. Design of the hybrid nuclear power plant provides for the presence of a built-up high-temperature circuit, where a portion of fresh steam of the steam generator is directed for overheating on organic fuel and subsequent operation in a high-temperature turbine and mixing with steam after the separator-superheater. At that NPP is made with possibility of operation at partial load modes due to change of steam flow rate to high-temperature path by means of control valve opening degree change.

EFFECT: enlarging the range of variation of the generated power of the nuclear power plant and increasing the net efficiency of the power unit.
