In a nuclear power plant heat is transferred in the reactor to liquid sodium. The liquid sodium is then pumped to a heat exchanger where heat is transferred to steam. The steam leaves this heat exchanger as saturated vapor at 5 MPa, and is then superheated in an external gas fired superheater to 600°C . The steam then enters the turbine, which has one extaction point at 0.4 MPa, where steam flows to an open feedwater heater. The turbine efficiency is 75% and the condenser pressure is 7.5 kPa. Determine the heat transfer in the reactor and in the superheater to produce a power output of 80,000 kW. Draw a sketch of this cycle and a T–S diagram.
