Transcribed Image Text:A nuclear power plant based on the Rankine cycle operates with a boiling-water reactor to
develop net cycle power of 3 MW. Steam exits the reactor core at 100 bar, 520°C and expands
through the turbine to the condenser pressure of 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°C with a mass flow rate of
114.79 kg/s. Determine
(a) the thermal efficiency.
(b) the temperature of the cooling water exiting the condenser, in "C.
