What is the maximum portion of energy that can be supplied by nuclear?<2%.Nuclear power has produced only only 2% of our energy demand, uranium is projected by the IAEA to start to run short in just 8 years. Electricity is 20% of energy demand, nuclear is 10% of electricity demand.So for practical purposes the long term maximum nuclear power can produce is zero. Watch how fast nuclear power gets to zero when the uranium starts to run short. Nuclear power is already the most expensive power and losing in the markets even with government help against solar and wind without any government help.While the nuclear industry claims 100’s or thousands of years of fuel to the public, the official uranium resource guide, the Red Book, shows a shortage starting in just 8 years if the pr nuclear people get the build up they want.We would have 2 Fukushima disasters per year as well if we got all our energy from nuclear.Uranium mining is the dirtiest mining there is, and requires 2 million tons of rare earth type toxic mining per reactor per year.We don’t even know what to with the spent fuels wastes we have now.Anonymous's answer to Why do we need nuclear energy?
If an Aircraft Carrier had an emergency and had to sail at close to or at full speed can the fleet escorts keep up?
No. Due to their size and engine power American nuclear-powered aircraft carriers can outrun virtually every surface ship in most sea states. The rougher it is, the more they will be able to outdistance other watercraft. There are watercraft which can go faster than carriers, in good weather. In bad weather carriers will outrun almost everything afloat. An antisubmarine frigate can’t possibly keep up. A destroyer would have a better chance, but still would have problems. Since the old CALIFORNIA class nuclear cruisers were decommissioned, no American cruiser can keep up with a carrier. The Russian KIROV class battlecruisers might be able to stay with a carrier, maybe, but not for long, especially in bad weather.Note that if you look up the official top speed of American carriers, you’ll see mealy-mouthed phrases like “in excess of 30 knots” as the Navy doesn’t want to say. USS KITTY HAWK once made a sprint in which she averaged 42 knots by simple math, and I’m pretty sure that later, nuclear-powered, carriers are faster than that. USS ENTERPRISE (CVN-65) allegedly once hit 50 knots. Allegedly. The Navy refuses to say. CVN-65 is now decommissioned and will be replaced by a GERALD R. FORD class carrier, CVN-80, which is, allegedly, faster than CVN-65.The only surface warships which could sustain speeds close to or superior to those of an American nuclear-powered carrier would be the various fast minelayers of the WWII era, such as the British ABDIEL or MANXMAN, both of which could exceed 44 knots. Very large transatlantic liners such as QUEEN MARY could also go very fast, for much the same reasons as the carriers. QUEEN MARY once rammed and cut in two a cruiser without slowing down.
