New Material Can Soak Up Uranium From Seawater (acs.org)
A new adsorbent material "soaks up uranium from seawater, leaving interfering ions behind," reports the ACS's Chemical & Engineering News, in an article shared by webofslime:
The world's oceans contain some 4 billion metric tons of dissolved uranium. That's roughly 1,000 times as much as all known terrestrial sources combined, and enough to fuel the global nuclear power industry for centuries. But the oceans are so vast, and uranium's concentration in seawater is so low -- roughly 3 ppb -- that extracting it remains a formidable challenge... Researchers have been looking for ways to extract uranium from seawater for more than 50 years...
Nearly 20 years ago, the Japan Atomic Energy Agency (JAEA) confirmed that amidoxime-functionalized polymers could soak up uranium reliably even under harsh marine conditions. But that type of adsorbent has not been implemented on a large scale because it has a higher affinity for vanadium than uranium. Separating the two ions raises production costs. Alexander S. Ivanov of Oak Ridge National Laboratory, together with colleagues there and at Lawrence Berkeley National Laboratory and other institutions, may have come up with a solution. Using computational methods, the team identified a highly selective triazine chelator known as H2BHT that resembles iron-sequestering compounds found in bacteria and fungi.... H2BHT exhibits little attraction for vanadium but has roughly the same affinity for uranyl ions as amidoxime-based adsorbents do.

Then go on about how renewable energy makes more economic sense than nuclear power.
That's an article about not reducing carbon emissions as much as expected, not about the choices not making economic sense. They also didn't build storage, because it wasn't economically workable at the time, either. Now it is.
There's a name for doing the same thing over and over again while expecting a different result.
You mean your constantly promoting nuclear power and then being slapped down with the same arguments, or do you mean my constantly trying to appeal to your ability to reason when it appears to be vestigial at best?
"You're right," Fisheye says. "I should have set it on 'whip' or 'chop.'"
