A nuclear power plant based an the Rankine cycle aperates with a boiling-water reactor to develop net cycle pawer of 3 MW. Steam exits the reactor core at \( 100 \mathrm{bar}, 520^{\circ} \mathrm{C} \) 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 \( 87 \% \) and \( 78 \% \), respectively. Coaling water enters the condenser at \( 15^{\circ} \mathrm{C} \) with a mass flow rate of \( 114.79 \mathrm{~kg} / \mathrm{s} \). Determine: (a) the percent thermal efficiency. (b) the temperature of the caoling water exiting the condenser, in \( { }^{a} \mathrm{C} \). Part A Determine the percent thermal efficiency. \[ p= \] \( \% \) Attempts: 1 of 3 used Part B Determine the temperature of the cooling water exiting the condenser, in \( { }^{\circ} \mathrm{C} \).
