85% of used fuel rods can be recycled to new fuel rods. And there's military uses for depleted uranium too. So, essentially every bit of the waste can be recycled. Can't say the same for fossil fuels.

"85% of used fuel rods can be recycled" is like "We can totally capture nearly all the carbon from burning fossil fuels and then remove the rest from the atmosphere by other means".

In theory it's correct. In reality it's bullshit that will never happen because it's completely uneconomical and it's just used as an excuse to not use the affordable technology we already have available and keep burning fossil fuels.

Capturing all the extra carbon from the atmosphere is not as expensive as it sounds like. It can easily be done by a few rich countries in very few decades once we stop adding more there every day.

Recycling nuclear waste is one of those problems that should be easy but nobody knows what the easy way looks like. It's impossible to tell if some breakthrough will make it viable tomorrow or if people will have to work for 200 years to get to it. But yeah, currently it's best described as "impossible".

What?

For starters, carbon capture takes an insane amount of power. And to follow up: we couldn't even build the facilities is "a few decades" even if we free power and infinite money.
