A nuclear power plant generates 3000 MW of heat energy
Chapter 21, Problem 21.81(choose chapter or problem)
A nuclear power plant generates 3000 MW of heat energy from nuclear reactions in the reactors core. This energy is used to boil water and produce high-pressure steam at 300C. The steam spins a turbine, which produces 1000 MW of electric power, then the steam is condensed and the water is cooled to 25C before starting the cycle again. a. What is the maximum possible thermal efficiency of the power plant? b. What is the plants actual efficiency? c. Cooling water from a river flows through the condenser (the low-temperature heat exchanger) at the rate of 1.2 * 108 L/h ( 30 million gallons per hour). If the river water enters the condenser at 18C, what is its exit temperature?
