"properly sequestered" is the key word. There is no such thing.

Here in Germany, we still have not found where to put nuclear waste long-term, and there is no solution in sight.

Even if one day we find one, how do we communicate the potential dangers of nuclear waste to a civilization that is supposed to understand what we're communicating in 30000, 50000 years? With a fancy unicode symbol, like U+2622?

We have no idea what people 3000 years ago were trying to tell us with their fancy symbols.

Nuclear energy is the analogy of tech debt that can never be paid back, ever.

The reason why the "waste" is dangerous is that there's a lot of energy in it - energy that can still be extracted at a later date. It might very easily be very valuable in the future.

Germany is really sad case, where they stopped using nuclear and replaced it with "clean coal". Terrible thing for the planet.

The Greens talk about nuclear waste and Fukushima, and meanwhile German green-washed coal plants and cheating diesel engines put crazy things in the air.

With advanced reprocessing as well as waste-burning containers, the question is about communicating it for ~200 years, not 50000 years. And it would also increase our efficiency in using the fuel to boot.

Vitrify it, clad it with concrete, clad that with steel and dump it in a subduction trench where it’ll eventually join the magma under the mantle.

Let's see. Deepest hole drilling: 12km - Thickness of continental lithosphere: at least 100km. How will you get your nuclear waste there?

That does not mean the solution does not exist or that it is hard. Germany government chose to reject nuclear, I am not expecting that it would then work towards making nuclear more popular.
