Sorry I somehow just saw your response. Here's mine:

• Nuclear waste being trucked through my area is completely fine because not only has it already been contained and simply being trucked to it's longterm storage site, it's not some glowing ooze that's super hard to keep from seeping into places. It's a solid. Have the trucks stay away from running water and don't drive on days that it's raining, and even if there's a crash it's not gonna get into the ecosystem. Add to that, the alternative for baseload power has been fossil fuels, which are shown to not only be more hazardous to the immediate area and people, but more hazardous to the planet. So the options for the past several decades has been between a verifiably bad thing, and a verifiably not bad thing. This is just more either uninformed or alarmist rhetoric.
• A similar question can be turned around on solar, what with the huge amount of material that needs to be mined in toxic processes for the rare earth metals that are needed for photovoltaics + battery banks. And you're complaining about needing tires for moving nuclear waste? Really? The addition would be negligible compared to what's already on the roads. This is just grasping at straws.
• We don't have that kind of time because people like you have been preventing us from building safe plants for decades. This is the same kind of energy as when republicans defund government agencies and then use the now lower productivity of the agency as an example of governments being bad at jobs. We've lost time because you've been holding our head underwater.
• Realistic nuclear disarmament is a pipe dream that gets obliterated with 5 seconds of thought. The countries we truly want disarmed will never do such, and better countries disarming would just lead to those first countries becoming emboldened to use their arsenal. The only realistic result of nuclear disarmament is a nuclear war perpetrated by dictators.
• If human civilization breaks down to the point that top security assets are unmanageable, there's far worse issues going on than nuclear waste getting into the ground water in a couple specific locations. Not to mention a scenario like you bring up would have to have humans falling back to the stone age, at which point the change in quality and length of life from the nuclear radiation a leak would bring wouldn't be very substantial compared to their stone-age alternative.
