It does serve as a wonderful example of exactly what they are talking about, funny enough.

I agree with you that climate change > nuclear waste. It is the poly-crisis that touches everything. And I agree that nuclear stuff can be overblown. Most of the time it is fine. But when it goes wrong, it REALLY goes wrong with long term consequences that stretch into tens of thousands of years. It will be dangerous longer than we have had writing or civilization. We will need to signal its danger beyond the current confines of human speech. I feel similarly about the idea of some forms of pollution which will affect places for thousands of years. The thing that gets me is the timescale.

I was watching a post-apocalyptic show the other day and started wondering: if society suddenly collapsed, what would happen to the nuclear power plants? I mean, I know that there are procedures to ramp them down but what then? How would you decommission a nuclear power plant without electricity? Without expertise? What would happen to all the nuclear weapons? I have always wondered if there are catastrophic scenario SOPs for these things.

Now, I have thought that if society does collapse, it will happen more gradually than suddenly. But this little thought exercise made me think that nuclear waste / nuclear energy is one thing that necessitates a certain level of knowledge, expertise, and energy to maintain. A certain level of civilization or modernization.

Again, I could be wrong and I'm willing to change my mind, but that is where I stand at the moment.
