A nuclear power plant generates 3000 MW of heat energy from nuclear reactions in the reactor's core. This energy is used to boil water and produce high-pressure steam at 320 ∘C. The steam spins a turbine, which produces 1000 MW of electric power, then the steam is condensed and the water is cooled to 25∘C before starting the cycle again. Part A: What is the maximum possible thermal efficiency of the power plant? Part B: Cooling water from a river...

Question 3 [30 marks] A reheat Rankine cycle is designed for a steam power plant. Steam enters both the high- and low- pressure turbines at 600oC. The maximum and minimum pressures of the cycle are 20 MPa and 20 kPa, respectively. Steam leaves the condenser as a saturated liquid. The moisture content of the steam at the exit of the low-pressure turbine is 4% if the actual expansion process is adiabatic; 8.5% if the ideal expansion process is isentropic. The...
