> "Nuclear waste in canisters has never hurt anyone"

This is an interesting statement, and though true I think it's a bit disingenuous.

I'm no expert on nuclear or nuclear power, but I recently listened to a Canadaland podcast about nuclear waste [0] and did a little extra reading [1][2] on deep geological nuclear disposal. If what I heard/read is to believed, it sounds like although the international science community has agreed on the best and safest way to bury nuclear waste, this hasn't _actually_ ever been done.

It's one thing to say to a community "in theory, we all agree that if everything is done correctly this is the best solution" and another COMPLETELY to trust that 1) The task will be done right, 2) The governing body (NGO, government, etc) will be around for the full lifetime of the nuclear waste being a threat (~150+ years), and 3) Said governing body will be well-funded enough the entire time to do the job right.

I believe that the engineering solutions are sound, but I don't think it's fair to dismiss the concern "often good science isn't executed very well". Until this is addressed, I'm not sure "but the science says!" is going to be a very effective response. For something as high-stakes as this, we need a more comforting guarantee.

We might compare to what happened next to the Farallon islands, off California. At least 47,500 barrels of nuclear waste, weighted with concrete, just dropped in the water. (Those that floated anyway were shot.)

The fate of the barrels was an example in my differential equations course. (tl;dr: They burst when they hit the sea floor.) Wikipedia suggests that "by 1980, most of the radiation had decayed". Excepting what hadn't, of course.

All that observed, the problem with nuke plants is absolutely not the waste. The overwhelming problem is the outrageous cost, and that they don't start displacing fossil fuels for years, if ever. A dollar sunk into a nuke plant instead of renewables is simply sunk, as far as the climate is concerned.

>The overwhelming problem is the outrageous cost,

The cost of consumer rooftop solar is as high or higher than nuclear, do you also think that cost is outrageous and we should abandon it?

>...and that they don't start displacing fossil fuels for years, if ever.

Solar, wind and nuclear have about the same carbon footprints. A few links:

Oddly, my solar projects have not had 5x, 3x, or even 1.5x cost overruns, never mind multi-year unplanned delays. And, they started producing immediately.

Carbon footprint is not in play.

There are some examples I can think of where nuclear waste is being stored underground:

By people: underground nuclear bomb tests Naturally: there are some spots where nuclear fission reactions have happened on their own, leaving the waste where the fissile uranium used to be

These aren't going to be the same contents as what power plant waste looks like, of course, but they certainly provide some evidence on how safe/not safe it is

The nature did this in Oklo 2 millions years ago, it did work quite well tbh, as we only found out recently. It wasn't even that deep.
