How much more energy efficient are nuclear plants compared with coal-fired plants? How many more MWs of power do nuclear power plants produce than coal-fired plants?
The nuclear power stations make steam from the heat of rector and drive turbines to produce power.It is almost same process except the source of heat.
Capacity of a plant depends upon design.
Since nuclear plant uses steam at lower temperature due to safety factors they may be less efficient most used fuel in power generation is coal...Gas, hydro plants come next.
