POWER PLANT WITH GAS-COOLED REACTOR Russian patent published in 2000 - IPC

FIELD: heat power engineering. SUBSTANCE: proposed plant which uses nuclear reactors as high-temperature heat sources is designed for self-contained stationary and mobile objects. Heat reactor is removed by means of gaseous coolant (helium) circulating in circuit. Owing to heat exchange with helium, condensate in steam generator evaporates producing the steam and then steam is overheated with provision of pressure rise in heat exchanger-heater. Steam expands in turbine executing useful work converted into electric energy by means of electric generator. Steam from turbine passes into condenser where it is condensed owing to heat exchange with cooling system. Then condensate gets into steam-water pump-heater. Simultaneously with condensate, steam gets along line through regulating valve into steam-water pump-heater in which intensive mixing of steam and condensate takes place with provision of heated condensate of high temperature and pressure. Owing to this pressure. heated condensate is conveyed into steam generator. Check valves are provided to control direction of steam flowing. EFFECT: increased efficiency of plant, reduced mass and dimensional characteristics. 1 dwg
