Which currency is the best heat source? I think some of the newer ones might give you cancer.

Fossil fuel heat generation is an order of magnitude cheaper per unit than electric in many geographic areas.

> We have enough uranium to last for millions of years at current consumption levels

this is because we don't use very much nuclear power. There is currently enough known uranium reserves to provide 2 years of global energy production at current rates.

See "closed nuclear cycle" and breeder reactors.

That's one to two hundred years depening on if you include inferred resource, and for supplying under 3% of the energy. Meeting net zero targets with PWRs would run out in well under a decade, perhaps not even a single fuel load.

Well, PWRs are dead end, we need breeders.

So if we just do this thing that doesn't work and would be more expensive as the other thing that's too expensive and release many EBq of Kr-85, H3 and probably various other fission products we can avoid doing the thing that's currently working and is dirt cheap.
