A nuclear power plant based on the Rankine cycle operates with a boiling water reactor to develop net cycle power al 3 MW Steam exits the reactor core at 100 bar, 520 C and expands through the turbine to the condenser pressure 1 bar. Saturated liquid exits the condenser and is pumped to the reactor pressure of 100 bar. Isentropic efficiencies of the turbine and pump are 81% and 78% respectively. Cooling water enters the condenser at 15 with a mas flowrate of 114.79 kg/s.
