According to Our World In Data (which claims to use the Energy Institute's Statistical Review of World Energy from 2023 as a data source), that waste is from producing around 70 TWh each year:

That only covers around a third of Switzerland's energy consumption over those years. Furthermore, Switzerland is a small mountainous country with decent access to hydropower (making up around a third of its needs over the same years). They are not necessarily representative of the waste that would accumulate from a more agressive switch from fossil fuels to nuclear across the world (which is what we're talking about, if I'm not mistaken).

France is about 10 times larger in surface area and according to the same source, consumed/produced over 1,000 TWh of nuclear energy each year:

And officially has still has no place to put the high-energy waste (source - in french), leaving it up to the plant's owners to deal with it. There is an official project to come up with a "deep" geological storage facility, but no political will seems musterable to make that plan materialize beyond endless promises.

I should mention that I'm not super anti-nuclear, and I would certainly rather we focus on eliminating coal and oil power plants (and ideally natural gas ones as well) before we start dismantling existing nuclear reactors that are still in functioning order.

That being said, there are other problems with nuclear moving forwards besides waste management. The main one that worries me is the use of water for the cooling circuits, pumped from rivers or the sea. Not only do open cooling circuits have adverse affects on their surrounding ecosystems, as the planet gets warmer and the temperature swings during the hotter seasons become more pronounced, the power plants will become less efficient. The water going in will be at a higher temperature than it is today, and thus will absorb less energy from the nuclear reaction itself.

Overall, I don't trust our current collective responsibility as a species to manage our current forms of nuclear production. Russia sent its own troops into the Chernobyl Exclusion Zone to dig trenches in contaminated soil last year, and they allegedly recognized last week that the Zaporizhzhia power plant is now "unsafe to restart" because of the military activity in the region.

The world has not experienced generalized warfare with nuclear power plants dotting the countryside; WW2 ended around a decade before the first nuclear power plants were up and running in the USSR, the UK, and the USA.

Not to mention how few European countries have access to uranium on their own soil/territory. Of course, most of the rare earth metals used in photoelectric panels and windmills aren't found there either, but as least with "renewables" they are used once to make the machinery, not as literal fuel that is indefinitely consumed to produce power.

I don't know enough about thorium-based reactors nor molten salt-based reactors to go to bat for them instead, but they seem like a more promising way for nuclear to remain relevant.

In Germany, we've got a location with 47,000 cubic meters: https://www.bge.de/en/asse/
That requires some pretty tall stacking on that football field. Or I guess, you're saying if you'd unpack it all and compress it?

Also, we really should be getting the nuclear waste out of said location, since there's a known risk of contamination. But even that challenge is too great for us, apparently.
Mainly, because we don't have any locations that are considered safe for permanent storage. It's cool that Switzerland has figured it out. And that some hypothetical football field exists. But it doesn't exist in Germany, and I'm pretty sure, Switzerland doesn't want our nuclear waste either.

That is a horribly naive underselling of what's involved in storing nuclear waste. How do you transport it? What do you do in the event of an accident during transport? Where is it stored now? Is it somewhere we can get good transport in? How do you mark something "do not enter" for tens of thousands of years? Think of what languages existed during the Roman Empire, and then realize that we'll have to store it for orders of magnitude longer than that.

Logistics, logistics, logistics. They are not easy for even the simplest projects.

We do have the recycling technology. It's not a far off thing; been developed for decades. If there's a good reason for a nuclear renaissance, it's in using the waste we already have, and recycling it down to something that's only dangerous for centuries, not millennia.

The two nearest nuclear plants to me both had to do serious cleanup after problems were discovered, it's not just the list of big problems people worry about - especially when the nuclear lobby say things like 'they're safe as long as they're run properly and no one cuts corners, but please don't regulated them properly or they won't be cost effective'

Rich people stand to make a monopoly if we're all dependent on nuclear and they can't have that monopoly with solar and wind - maybe it's time to accept a lot of pro nuclear talking points come financially interested parties too.
