System Performance Analyses of Supercritical CO2 Brayton Cycle for Sodium-Cooled Fast Reactor

The system performance of the supercritical CO2 Brayton cycle for Sodium Fast Reactor with a partial-cooling layout was studied, and an economic analysis carried out. energetic, exergetic, exergoeconomic analyses are presented, optimized results were compared recompression cycle. sensitivity conducted by considering variations in pressure ratios inlet temperatures main compressor turbine. exergy efficiency reached 63.65% net power output 34.39 MW via optimization. obtained minimum total cost rate 2230.36 USD/h when ratio equal to 3.50. temperature 35 °C, turbine 480 °C. recuperators decreased increase compressor. In addition, recuperator could be reduced increasing outlet change from loss destruction substantially larger than or Manipulating is essential method guarantee good economy system. Moreover, capital investment, operation, maintenance costs normally accounted large proportions rate, being almost double occurring each condition.
