I feel like this has been absent in many pro-nuclear arguments (I always assumed we had much more)

The other fuel used would be plutonium and thorium, I believe. My understanding (not a nuclear scientist) is that there's a cycle of enrichment and decay that produces more fissile materials than it consumes.
Interestingly, from my perusal of wikipedia, it seems like you effectively can recycle the uranium isotopes indefinitely in such a reactor, as well as generating fissile plutonium and thorium.
Again, the problem is that generating fissile plutonium is how you make a bomb
China is leading the way, both in terms of adding coal capacity right now to address the power outages while also building out nuclear capacity for the future.
The ability to act rationally like this when popular movements turn irrational is one advantage of an authoritarian system. No doubt many in the west are looking somewhat enviously at China.
So, the Chinese are spending way more money than they should on building super duper expensive coal plants that can’t effectively run on the kind of coal that they can get. And they have a coal embargo against Australia, so they can’t import the stuff that they could actually burn effectively.
Meanwhile, solar panels have continued to get progressively less expensive, so that even in China, it is now cheaper to run solar panels than it is to burn coal.
Increased uranium prices will not significantly affect energy cost, as fuel price is very small fraction of nuclear plant operation.
These days there are ways of getting uranium from sea water [1], basically making the supply practically limitless. This way is currently un-economical, but as current reserves are depleting, it will become viable option as well. (Along with researching for more reserves)
So yes, it was totally possible to decarbonise electricity production long ago.

Breeder reactors can make fuel during use.
We only need enough fuel for one reactor.
