https://12ft.io/proxy?q=https%3A%2F%2Fwww.scientificamerican.com%2Farticle%2Furanium-extraction-from-seawater-takes-a-major-step-forward%2FThere are a lot of sources you can find that talk about the idea of extracting uranium from seawater, but that one is nice because it gives you some concrete numbers to play with in a spreadsheet.
Once you do all the calculations you find the process described can supply nuclear power at an implied rate of 1450 watts per kg of filter material. That's fairly decent, especially if the filter material can be reused.
On the other hand if you used a more efficient molten salt reactor design that includes online reprocessing so that you can use all the uranium instead of throwing most of it away the 27,000 kilograms / gigawatt-year mentioned at the bottom of the page drops to about 1,000 kilograms per gigawatt-year.
Rerunning the numbers with that now your extraction process is worth 39100 watts per kg of filter.
Those are the kinds of numbers you need to build a viable settlement out in the middle of the ocean. 26 tons of filter active continually will keep a 1 GW molten salt reactor fueled. Now you have plenty of energy to not just keep yourself alive but also power manufacturing and agriculture so that you have products worth selling.
