We have plenty of uranium. For all intents and purposes, we have an infinite supply of uranium that would have minimal environmental impact to mine, at roughly 2x existing prices of ore mined from the ground.
As for wastes, all the truly nasty stuff will be naturally decayed in a hundred years or so. And we have real solutions that we don't use for political reasons.
I’ve seen wildly divergent estimates for how much uranium we have. Personally I’d rather use renewable and storage for the ground, and keep the atomic fuel for spacecraft just in case we can’t make lightweight fusion engines.
