What is the advantage of nuclear power for aircraft carriers?
What is the advantage of nuclear power for aircraft carriers?
High-Power Density. When compared to its conventional counterpart, a nuclear aircraft carrier can carry twice the amount of aircraft fuel, 30 percent more weapons, and 300,000 cubic feet of additional space (which would be taken up by air intakes and exhaust trunks in gas turbine-powered carriers).
Are nuclear powered ships better?
The United States Navy alone has over a hundred nuclear reactors that power 86 submarines and aircraft carriers, producing electricity, heat and propulsion. Besides fuel savings, nuclear powered ships go about 50\% faster than oil-fueled ships of the same size.
Are all US aircraft carriers nuclear powered?
All US aircraft carriers and submarines are nuclear-powered. There were 10 Nimitz-class carriers in service (CVN 68-77), each designed for 50-year service life with one mid-life refuelling and complex overhaul of their two A4W Westinghouse reactors*.
How far can aircraft carriers go?

What are the advantages of nuclear-powered aircraft carriers?
For example, conventionally powered carriers spend less time in maintenance, and as a result, they can provide more forward presence coverage. By the same token, nuclear carriers can store larger quantities of aviation fuel and munitions and, as a result, are less dependent on at-sea replenishment.
What are the disadvantages of using nuclear power to power ships?
There are problems with this technology, with the leading one being the expense, the nuclear powered ships are much more expensive than those with the conventional sources of power (They are petroleum based), especially during the peace times.
Why don’t nuclear-powered ships have stacks?
Since nuclear reactors do not produce the exhaust gases of ships powered by fuel oil-fired boilers, nuclear-powered ships do not require stacks, which does free up a certain amount of room on a carrier’s island.
Are nuclear-powered ships environmentally friendly?
The nuclear ships are environmentally friendly, The nuclear fission releases no greenhouse gasses, the confinement against radioactive leakage is excellent , and the nuclear ships are even recyclable.
