Question

Part C: What fraction of the max efficiency is the power plant's actual efficiency?

Each second, a nuclear power plant generates 2800 MJ of heat energy from nuclear reactions in the reactor's core. This energy is used to boil water and produce high-pressure steam at 330 °C. The steam spins a turbine, which produces 700 MW of electric power, then the steam is condensed and the water is cooled to 50 ° C before starting the cycle again.

Explanation / Answer

maximum possibel efficency is

e = 1- T2/ T1 = 1- 50 + 273/ 330 + 273 = 0.464 or 46.4 %

(c)

e _act/ e_max = 0.25/ 0.464 = 0.538
