FIELD: nuclear energy.
SUBSTANCE: invention is related to a double-circuit nuclear energy system with hydrogen-containing working fluids in each circuit. In reactor core 1, the released nuclear fission energy is transferred to the hydrogen-containing working fluid of liquid circuit 2, diathermic oil, circulating through liquid circuit 2 due to the operation of circulation pump 3. The hot diathermic oil of liquid circuit 2 transfers thermal energy to the working fluid of steam circuit 5 with the working fluid pentane. From steam generator 6 of steam circuit 5, superheated pentane steam under high pressure enters steam turbine 7 with electric generator 8 on the same shaft. Due to rotation of turbine 7 in electric generator 8, electrical energy is generated. Passing steam turbine 7, pentane vapor reduces the pressure and enters condenser 9, where it is condensed due to cooling by the cooling medium of cooling system 11. Then liquid pentane is supplied again to steam generator 6 using liquid supply pump 10. Unified cooling system 11 with control valves 12 and 13 provides an independent supply of cooling medium through condenser 9 of steam circuit 5 and heat exchanger-cooler 4 of liquid circuit 2 of the nuclear power system.
EFFECT: increase of efficiency and reliability of the nuclear energy system, reduction of the accident rate of the nuclear reactor, the weight and size characteristics of the nuclear reactor and the pipelines of the liquid circuit of the nuclear energy system.
