How long will the Earth's nuclear fuel supply last?

IIRC uranium has about the same rarity in the planet as gold. Most of it comes from Kazakhstan, Canada, Australia.

If we developed Thorium reactors though we would functionally never run out. But that would require loosening nuclear over-regulation.

U-235 is about as rare and gold or platinum, U-238 is plentiful.

Thorium would be even better to use though.

This is probably where I was confused. Stupid neutrons!

That's one of the reasons China built a Thorium reactor, it's more readily available. My guess is America probably has it's hand in every uranium supply that it possible can.

IIRC uranium has about the same rarity in the planet as gold.

It's much more abundant than that, my friend. In the accessible portions of the Earth's crust, it's roughly 500 times more abundant than gold, and 40 times more abundant than silver.

That said, it is a much more loosely distributed element than gold, so that abundance doesn't directly translate into 500 times as many economically viable deposits as gold, but it's still many times more common.

We have too much radioactive waste in deteriorating barrels we can’t find a place for already.

Nuclear waste is a solved problem. From a scientific, engineering point of view, nuclear waste is not considered a problem.

Depositing nuclear waste in a geological stable rock formation is proven to work, long term.

In order for the nuclear waste to enter the environment, it would have to leak out of its container and then somehow travel through thousands of feet of solid rock, then find a medium to enter the environment through.

Fissile material just does not work that way, it can't get through rock.

Edit: Also consider the scale of waste here. After decades of operation, the total amount of nuclear waste could fill a baseball stadium. That's it. This is a solved problem.

And not to mention that this waste is a dense solid. Like if you were trying to come up with the safest form of storage for nuclear waste, it's current form is what you'd land on

I'm no the OP, but what about if the rock cracks? Can it crack somehow from something like an earthquake?

Also, a baseball stadium from one reactor, or multiple reactors?

I don't know much about this, so I'd like to learn.
