The presentresearchconcentrates on the energy and exergy analysis of the S-CO2recompression Brayton cycle and the individual components irreversibilities by varying the different operating parameters.Results show thatthecycle efficiencies and LTR effectiveness reduce by increasing minimum cycle temperature, but HTR increases.The effect of minimum cycle temperature is more critical on cycle performance than maximum cycle temperature.The reactor hasthe highest irreversibility followed by recuperators and pre-cooler. Exergy efficiency shows a downward trend as environment temperature enhances. However, the effect of turbine inlet temperature is very low on-cycle efficiency and optimum pressure ratio for lower compressor outlet pressure values, which is more significant by increasing this parameter
