THERMAL SYSTEM OF GAS-COOLED REACTOR OF NUCLEAR POWER PLANT Russian patent published in 2018 - IPC G21C15/00 

FIELD: power industry.

SUBSTANCE: heat system includes a gas turbine and steam turbine heat recovery cycle, using helium as the working fluid of the gas turbine cycle and steam as the working fluid of the steam turbine cycle. The gas turbine cycle comprises a gas turbine whose shaft is connected to an electric generator and a compressor, the input of the cooling system of the reactor is communicated with the compressor high pressure cavity and its outlet is communicated with the input of the gas turbine. The output of the gas turbine is communicated with the steam generating unit which comprises a first superheater, an evaporator, a second superheater and an economizer-evaporator that sequentially communicated. At that, a steam-water drum is included in the steam turbine cycle.

EFFECT: increased efficiency of the nuclear power plant of combined cycle, significant reduction of weight and dimensions of heat exchangers by applying the steam turbine cycle that contains the turbine of high and low pressure, and steam intermediate reheat.
