If we needed more nuclear fuel we would be producing more of it. Comparing current production to a world where we use a thousand times more of it is ridiculous. Uranium is not that rare, and spent fuel rods still have well over 90% of their potency so they can be recycled.
Nuclear energy could easily power the entire planet for thousands of years.
Sure, we could produce more. It would have to be from much lower grade ores, and so would be much more expensive and disruptive. This is why breeding would be needed, so the cost of the uranium would not make nuclear even more unaffordable than it already is.
