I have an encyclopedia Brittanica, early eighties. In the article on
fossil fuels, where it discusses oil shales.

"It was estimated by Victor Goldschmidt in 1933 that the quantity of
sedimentary rocks in the Earth's crust amounts to 300,000,000 cubic
kilometers. The oil-shale and asphaltite reserve is about 10**13
tonnes, and their uranium concentration has been estimated as 0.01
percent."

According to wikipedia, currently economically minable ores start at
0.05 percent.

This is a massive resource of uranium in such vast quantities that
issues about waste disposal seem trite.

I don't think there is that much U in any but very unusual shales,
but energy breakeven seems easy enough even for once-through
burner reactors powering rock crushers crushing "country rock" --
0.00025 percent U. No-one believes uranium is going to be a limiting
factor for nuclear power expansion in this millennium.

Precisely.

But certain fraudulent propagandists certainly are pretending
to believe even this. This shows up the fanaticism, on the
part of some small but powerful cliques in the world,
behind the anti-nuclear-energy campaign.
