If the abundance of Uranium in the Earth is around 10ppb...
then the total mass of U in Earth is around 3e19g
that's around 1e19 moles (virtually all U-238), corresponding to 3e23 decays / second, which would generate at most 2-3TW of power (attributing the entire 52MeV decay chain energy to each decay of U-238
But U-238 supposedly generates up to 20-30TW of power, up to 10x as much
Moreover, the (continental) Crustal abundance of U is 3mg/kg, and the total bulk Crustal abundance of U is 1mg/kg
Given that the Crust masses around 2-3e25g, that already implies 3e19g of U... i
All of Earth's U resides in the (continental) Crust alone ?
Doesn't that strongly suggest, that there may well be more U on and in earth, than indicated by the abundances of meteors & solar photosphere ?
