FIELD: nuclear power engineering. SUBSTANCE: nuclear heating plant is provided with steam-turbine unit that has high-pressure steam generator 18 and low-pressure steam generator 19 series-connected on heating side, steam turbine 20 with electric generator, condenser whose function is performed by heating-system make-up water heaters 11,13. Steam generators are inserted in intermediate loop in parallel to heating-system heat exchanger 3. Additional heating-system heat exchanger 22 is mounted between heating-system heat exchanger 3 and suction end of circulating pump 5 for better reduction of coolant temperature. Power generated by turbogenerator of steam-turbine unit is used for ancillary power supply of nuclear heating plant and for feeding external loads. EFFECT: improved design. 1 dwg
