Question

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, 52O degree 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 l00 bar. Isentropic efficiencies of the turbine and pump are 81% and 78%, respectively. Cooling water enters the condenser at 15 degree 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 condensor in degree C.
