Nuclear carriers do take on Fuel despite being nuclear but it is not every day,[nit picking]
they also take on more than just JP-5 for their air wing, this might surprise you but they also act as a tanker for the battle group they sail with. [I am surprised but I see the logic] and do unreps with them for food and fuel.
Modern ships also do not burn Bunker oil, that generates billowing clouds and isn't efficient, modern warships are Gas steam turbine driven, they run on Diesel. [Whatever]
Lark wrote:Saturated means that the steam is at saturation conditions. If it gets a degree cooler and stays at the same pressure, it condenses into liquid water. If it gets any hotter, it becomes superheated. I had to read about it to understand it. When the water is boiled in the steam generator it passes through some moisture separators to ensure the steam is not pushing water droplets down the steam pipe. I was told that if there is too much water in the steam then the water crashes into the turbine blades and erodes them away or can break them off and then it is real trouble because they could shoot out of the turbine and kill someone in the engineroom.
I heard some of the larger land based plants operate at higher temperatures so they have better efficiency. The sub plant is much smaller and simpler than other nuclear power plants. One guy told me that the sub plant is so rugged and simple that most of the heat is lost to the sea in the condensor. Wikipeda says that the 165 MW reactor plant has 26 MW engines pushing the boat. This is like only 15% effeciency. I do not know if this is true, but if it is then they are really wasting lots of power.
