> Uranium is incredibly cheap. Prospecting is not worth it as there are enough reserves to exploit in the foreseeable future.

A huge uranium bubble between 2004 and 2008, which triggered massive investments for prospection... and a ridiculous result (15%). The cause is known: the quest for atomic weapons triggered during the 1950's and 1960's massive prospection, and there is no decisive way to better prospect and few not yet prospected zones.

> Seawater extraction is starting to be competitive with mining

This is periodically announced since the 1970's, and no-one could industrialize. Bottomline: "pumping the seawater to extract this uranium would need more energy than what could be produced with the recuperated uranium" Source: http://large.stanford.edu/courses/2017/ph241/jones-j2/docs/e...

It would be sound if a ready-for-deployment model of industrial breeder reactor. There is none.

> And then there's Thorium

Indeed, but not industrial reactor. Next.

LOL. An overview article that was obsolete even in 2016 when it was published. You need to get with the times.

"... the amount of uranium in seawater is truly renewable as well as inexhaustible."

"New technological breakthroughs from DOE's Pacific Northwest (PNNL) and Oak Ridge (ORNL) national laboratories have made removing uranium from seawater economically possible."

A speculative bubble is not the same as serious serious demand, and the actual demand never materialized. The vast majority of the "prospecting" was just speculators, not serious mining companies. And for serious prospecting, the 4 year time-frame was way too short, you just barely get done with the early stages of

- land acquisition and permitting

- Geological surveys (airborne radiometrics, mapping, geochemistry)

- Target generation

- Initial drilling programs

- Preliminary resource estimates (if successful)

You don't have enough to get to actual serious exploration and feasibility studies:

- Infill drilling

- Metallurgical testing

- Environmental baseline studies

- Scoping and feasibility studies

- More permitting

- Community consultation

Breeder reactors exist, they face the same problem as recycling: mined uranium is still way too cheap to make investment in those technologies economically attractive.

Should Uranium get more scarce and thus more expensive, the economic incentives change very quickly and then we can pull those technologies off the shelf.

Same for Thorium reactors: currently not necessary, as we have plenty of Uranium for the existing Uranium based designs. Doesn't stop companies like Copenhagen Atomics from investing, as they see other advantages in addition to very readily available fuel.
