A gas cooled nuclear reactor drives a closed cycle turbine 3

A gas cooled nuclear reactor drives a closed cycle turbine, 3, 300 kg/s of CO_3 enters the gas turbine at 677 degree C, 40 bar and exits at 187 degree C, 10 bar. What is true work output of this turbine?

Solution

true work output = m*C_p*(T₁-T₂)

here, T₁ = 677 C = 950 K & T₂ = 187 C = 460 K taking C_p = 0.844 KJ/Kg K assuming as standard value (not given)

= 3300*0.844*(950-460) = 1364.784 MW
