description: In this study, the selection of carbon dioxide as working fluid of a supercritical Brayton cycle between alternative supercritical fluids was justified. A nuclear reactor rated as having 600MWth has been used in conjunction with a simple sCO2 Brayton cycle. The inlet parameters of inlet temperature of compressor and turbine have been chosen as 32Â°C and 550Â°C respectively. High pressure side of the cycle was kept constant at 20MPa while the effect of pressure ratio was studied as a sensitivity study. Pressure ratio of 2,6 was selected as it was economically and thermally optimal between the pressure ratio values of 2 and 2,7. The efficiency of the cycle was found to be as high as 70% due to the back work ratio of the system being only 16%. Increases in turbine inlet temperature and different cooling solutions such as hybrid cooling were found to be promising areas of improvement in economical, thermal and environmental areas.
