World reserves are estimated to be 8M tons.
That does not count uranium in seawater. While we currently can’t mine it at the same cost from seawater as we can mine it elsewhere, we can mine from seawater.
https://cen.acs.org/materials/Fishing-uranium-ocean-spider-silk/97/web/2019/07 suggests that currently, the price for uranium from seawater is six times as expensive as other sources. The price of uranium is not very important for the price of nuclear energy and paying six times as much for it wouldn’t be a problem.
