A nuclear power plant based on the Rankine cycle operates with aboiling-water reactor to develop net cycle power of 3 MW. Steamexits the reactor core at 100 bar, 620°C and expands through theturbine to the condenser pressure of 1 bar. Saturated liquid exitsthe 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°C with amass flow rate of 114.79 kg/s.
Determine:
(a) the percent thermal efficiency.
(b) the temperature of the cooling water exiting the condenser, in°C.
