@sickburnbro I found an estimate from the World Nuclear Association that the average grade is 0.1% of uranium in a mined ton.
Orano Group (Uranium mining company) says 0.7% of Uranium ore are U-235.

So for a mined ton, you get 0,000007 tons of U-235, equivalent to 168 MWh

Following the same calculation that puts nuclear at 5952 mined tons plus about a 1000 tons of reactor material
so 6952 vs the "terrible" 16,000 tons of solar. Not that far apart, but nuclear still comes out on top in this comparison.
