If I recall correctly (its been a few months sinces I've read up) the Navy did a cost of operation analysis on Nuclear power and it really is more costly in terms of the manufacturing, maintainance, and personel cost to have nuclear power. Even with the saving on fuel, the overall cost over the lifetime of the ship is much higher for nukes. Only after fuel cost reach 4-5 times the dollar per barrel that they do atm do the cost equalize. And with the navy budget strapped for cash as it is its really not worth it until in a few decades oil prices are much higher than they are right now.
