Abstract
An exergy and exergoeconomic analysis program is improved for the supercritical CO2 (sCO2) cycle with Sodium-cooled Fast Reactor (SFR). The recompression cycle is calculated with sensitivity analyses. And the optimized results with the highest of exergy cycle efficiency are presented. The recompression cycle is well worked with SFR. Based on the sensitivity analysis, with the setting ranges of parameters in this paper, the cycle exergy and energy efficiencies and the cycle total cost rate could affect significantly by the compressor pressure ratio, inlet temperature of main compressor and inlet temperature of turbine. Via the optimization, the exergy cycle efficiency could reach 66.58% outputting 32.50 MW net power. The minimum cycle total cost rate is 2088.88 $/h with the exergy efficiency of 64.72%.
