Superheated vapor enters the first-stage turbine at 16 MPa, 560°C, and the condenser pressure is 8 kPa. The mass flow rate of steam entering the first-stage turbine is 310 kg/s.

Steam and ammonia are the working fluids in a binary vapor power cycle consisting of two ideal Rankine cycles. The heat rejected from the steam cycle is provided to the ammonia cycle. In steam cycle, steam at 6 MPa, 650C enters the turbine and exits at 60C. Saturated liquid at 60C enters the pump and is pumped to the steam generator pressure.
