There is no industrial production; it's in the R&D stage. Current costs are estimated at about 6x uranium mining. Thus, it is not currently economically viable. With R&D, costs are expected to go down. If we go in on nuclear long term, uranium shortages in a few thousand years will make uranium more expensive.

We're comparing long term scenarios here: reprocessing vs. seawater extraction. The reprocessing + hot refabrication process has been done and is extraordinarily expensive. If seawater extraction at scale is indeed viable, it's long term prospects in my view are way better than reprocessing.
