It's not even the waste, that we still need to learn how to recycle. Or the apparent incapacity of any operator to reliably follow the theoretical safety guidelines...

If we put all our effort into a nuclear boom today, the plants will only arrive a decade or two after the planet has been cooked, it won't be enough to replace anything, and we will have to learn entire new ways to mine the fuel in a few decades before the stuff we can get easily is gone.

Meanwhile we are about half-way done with renewables, and the nuclear fans keep denying that...

Forget it, i tried that argument a bunch of times. Also, you are depended on other countries, big plants are an easy target for a drone with some explosives, cost of nuclear is rising while all others are down, etc. People want to believe in a magic, water heating rock

I can see why people have been scared by the waste, but it's really not a concern. There are long term storage solutions, but they just haven't been implemented in many places. Kyle Hill actually just did a video on one the other day.

The waste just isn't a big enough concern to have put the resources into long term storage yet. The radiation level around the casks is so low that you can be around them and hug them without concern. Flying in a plane is more concerning. This argument is mostly fear mongering so we don't phase out dirty energy. We could have thousands of reactors running, but they've made us scared of the solution so we don't replace them.

Doesn't Sweden or someplace have a giant abandoned salt mine to store a thousand years of nuclear waste somewhere?

Not that I'm in favor of building nuclear anymore, we should've done that in the sixties.

Yes, but you need something with turbines to regulate power flow during off-peak. Hydropower can do that in some places, but not everywhere. That's the gap that nuclear should be aiming for (replace coal plants as minimum power regulator)
