We have basically unlimited uranium. There’s no risk of shortage. The average cubic meter of crust has more breedable fuel energy in it than a cubic meter of coal.
Fission is effectively as unlimited as renewable energy is, about a billion years’ worth of crust. Even if we stick with typical U235 reactors, sufficient uranium ore exists for hundreds of years, although no one will bother to formally “prove” the reserves for a constraint 100 years in the future.
What’s limited is the atmosphere’s capacity for CO2. Not much else matters in the mid/near-term, except perhaps for ensuring we have enough energy for civilization to function.
