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...

Consider a coal-fired steam power plant that produces 175 MW of electric power. The power plant operates on a simple ideal Rankine cycle with turbine inlet conditions of 8 MPa and 560°C and a condenser pressure of 8 kPa. The coal has a heating value (energy released when the coal is burned) of 29,300 kJ/kg and a CO2 emission value of 0.093 kg CO2/MJ. Assuming that 85% of this energy is transferred to heat in the boiler and that the...
