Anuclear 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.
