TEST III THERMO I 4/25/04 1) (33%) An engineering firm wants to design a nuclear power plant to provide heat transfer to a Carnot engine to provide power to electrical generators. The outlet temperature from the reactor (inlet to the Carnot engine) is 527°C, and heat transfer from the Carnot engine to the plant cooling water takes place at 27°C. The design power output of the Carnot engine is 1100 MW. a) How much power (MW) must be generated by the nuclear reactor to provide the required output from the Carnot engine? so = 1760 MW b) If river water is used as the thermal reservoir for the heat transfer from the Carnot engine, and EPA restrictions limit the temperature rise of the river to a maximum of 3.60°C at any time, what is the minimum mass flow rate required in the river, assuming that all river water is available for cooling? (Take c P for river water to be 4.177 kJ/kg . K) Heat transfer rate to river = = 1760-1100 = 660 MW First law on river, So = 43890 kg/s 2.) (34%) A Rankine cycle operates at a boiler pressure of 600 kPa, and the superheater
