Nice job providing sources for these numbers!
The real figure [1] is 60,000 years worth of uranium with our current nuclear energy production, which is about 10% of our electrical demand. So 6,000 years for a 100% nuclear grid. Electricity production is about 25% of total energy demand, so call it 1,500 years for all energy converted to nuclear.
Furthermore, moving nuclear seawater extraction - even at it's present costs, without economies of scale - would not significantly impact nuclear's costs [2]:
> Fortunately, the cost of uranium is a small percentage of the cost of nuclear fuel, which is itself a small percentage of the cost of nuclear power. Over the last twenty years, uranium spot prices have varied between $10 and $120/lb of U3O8, mainly from changes in the availability of weapons-grade uranium to blend down to make reactor fuel.
> So as the cost of extracting U from seawater falls to below $100/lb, it will become a commercially viable alternative to mining new uranium ore. But even at $200/lb of U3O8, it doesn’t add more than a small fraction of a cent per kWh to the cost of nuclear power.
