GP's claim is that seawater uranium is replenished from natural processes, not from reactor waste. That claim is true, and their link describes why. Here's another article: https://cna.ca/2016/07/27/theres-uranium-seawater-renewable/ https://cna.ca/2016/07/27/theres-uranium-seawater-renewable/ There is of course a finite amount of uranium on the planet. But there's also a finite amount of fusion fuel in the sun. Neither will run out before the sun boils the oceans. If we keep using fission long-term, it will likely be in the form of fast reactors, which get a hundred times as much energy from natural uranium because they don't just fission U235, but also U238 and transuranics. (Because of that, the waste from fast reactors only has to be securely stored for 300 years.)
