Unformatted text preview: piping and turbines or is consumed by the various pumps. Moreover, the generator converts rotational energy to electrical energy with high efficiency. The principal reason a the efficiency of a BWR or PWR power plant is less than the ideal Carnot efficiency is because of the irreversible nature of how energy is transferred from the hot fuel to the water coolant. To obtain the ideal Carnot efficiency in a closed cycle, all energy transfer must be between elements at infinitesimally different temperatures. In a reactor, the average fuel temperature is much higher than the water/steam coolant so that the energy transfer from the fuel to the coolant is done in a very irreversible manner, thereby reducing the overall thermal efficiency of the water/steam cycle.
