Yes I am aware of those. My question is: what makes you think that this poses a superior threat than other issues we face?
When I think about the future and its risks I never think about nuclear waste. I think primarily about global warming and all its consequences: massive migrations, droughts, fires etc.
To me these are way more important because
1) the likelihood is MUCH higher
2) the impact is MUCH higher
We are not talking about risk of disaster, we are talking about economic costs. And are are not comparing the cost to other disasters, we are comparing the cost of generating power using nuclear to other methods.
They need to be security because they can be stolen and the waste within can be used as a weapon.
