Science

...probably here - although I don't remember - and on other websites to which I was invited. The longest was on Barry Brook's website, "Is Uranium Exhaustible?" in which I discussed the geological uranium cycle through the mantle, to the crust, and ultimately the oceans, from which it can be recovered, albeit at a price higher than domestic ores. I'm not sure it's still available; I wrote in 2015. I note that the same technology can be used to remove uranium from groundwater that percolates through uranium ores (NORM - Naturally Occurring Radioactive Materials). Theoretically the uranium could be recovered for use.

I have a rather long list of papers on the topic in my electronic library.

I also wrote a piece on Rod Adams' website Atomic Insights: On Plutonium, Nuclear War, and Nuclear Peace

I believe it would be impossible for humanity to consume all of the uranium cycling through the crust, through rivers and ultimately into the oceans, with the possible caveat that the rate of consumption would matter. It does not seem unreasonable to assume that enough uranium leaches out of the crust to continuously supply the world's energy demand at say, 1000 EJ/year indefinitely, albeit with the requirement that ²³⁸U is converted in the fast neutron spectrum to ²³⁹Pu and beyond.

I believe you may be the first person with whom I have communicated to have actually worked on these materials.

Thanks for your comment.
