1. Radioactive waste gets less toxic over time unlike many toxins like mercury, lead, and cyanide. People seem to emphasize the duration of toxicity for radiation while apparently giving 'forever toxins' a total pass.
2. Short-lived radiation is what's really dangerous. When atoms are decaying fast, they're shooting out energy that can cause real damage fast. Longer-lived radioactive stuff with billion-year half-lives like natural uranium can be held in a gloved hand, no problem. In the extreme, and infinite half life means something is stable and totally safe (radiologically at least).
Yet people still want to emphasize that radioactive byproducts of nuclear power have long half lives. I don't really get it.
The question that matters for both industries is what bad things happen when their stewardship inevitably lapses and the happy path dead-ends.
I don't like either answer, so that heightens the urgency of pursuing alternatives with fewer long-lived hazardous byproducts. Neither coal nor nuclear is an acceptable long term solution.

This is fearmongering. Casing waste in big concrete casks is enough. It's so incredibly overblown that we're willing to burn coal and kill people over it.
Will it actually get encased successfully, will it be stored onsite in environmentally sensitive areas because it’s too much trouble to move, will your children’s children uphold the commitments you foisted on them through the political and economic turbulence in their lifetimes, and if not what happens comparatively when those coal ash heaps and nuclear fuel dumps are left to rot…
The externalities of concentrated radioactive material are not something that our socio-economic institutions are capable of handling at scale. Tragedies of the commons are the rule and eventually all of that waste will be go through periods of mishandling at one time or another.
Nuclear power plants have been extremely safe for many decades! Fuck, even the worst disasters related to nuclear power plants have killed less people than coal or oil disasters, even including Chernobyl which was a fuck up beyond comparison.
> Will it actually get encased successfully
Yes, this is literally done and has been done for many decades.
> will it be stored onsite in environmentally sensitive areas because it’s too much trouble to move
What does that mean? You can live 1 feet away from a cask and receive less radiation than you do from the sun.
> will your children’s children uphold the commitments you foisted on them through the political and economic turbulence in their lifetimes, and if not what happens comparatively when those coal ash heaps and nuclear fuel dumps are left to rot…
This is a bad argument because all of society relies on our grandchildren upholding present commitments. What happens if our grandchildren stop upholding the electricity grid? They die. What happens if they stop large scale agriculture? They die. And on and on and on.
> The externalities of concentrated radioactive material are not something that our socio-economic institutions are capable of handling at scale.
It's quite literally something society has been doing very successfully for 50+ years.
Rectang explained it very well, and all their points stand imo.
When I was a student I met a Chernobyl liquidator in his 30s on a local train. He said he was dying of leukaemia and looked like it. As a thought experiment, how would you argue to him that his death is unrelated?
Western part of USSR had also an explosion of thyroid cancers and tumors among children. Fortunately it was very treatabe. Because it was screened as a known consequence of the fallout my brother in law had an intervention early.
> Worrying about expanding nuclear and ending up putting the waste in a hole deep in the ground is such a nonissue to me.
Blithe minimization of the problem of storing nuclear waste over millenia feels like "Peak HN". :)
("Peak HN" jabs are a cheap shot, though — so let me engage more seriously...)
First, "coal vs nuclear" is a false dichotomy. Everybody I see advocating for nuclear power in this thread is advocating for it as a permanent solution rather than an interim solution — in which case there are other competitors.
Second, if nuclear waste is too dangerous for less-than-ideal storage conditions, that speaks negatively to the viability of nuclear power — because over the long term less-than-ideal storage is guaranteed by our inability to design incentive structures for responsible stewardship that persist over centuries.
Simply untrue. Finland‘s Onkalo is exactly that-a storage solution engineered to require zero stewardship. It is possible and now we know we can do it right. Storage is the weakest argument against nuclear.
By the way, Solar panels and wind turbines contain heavy metals with no decay path, e.g. Cadmium. Nuclear waste at least decays after apprx. 1000 years with spent fuel roughly as radioactive as the uranium ore originally mined for it.
The fearmongering against nuclear was always crazy to me. Especially since nuclear and renewables actually complement each other really well. We can use nuclear for baseload and renewables filling in on top when sun and wind are available.
> The fearmongering against nuclear was always crazy to me.
I sometimes feel similarly about pro-nuclear cheer mongering.
Similarly, while coal ash is nasty stuff that kills lots of people, it lacks many of the qualities that make spent nuclear fuel especially difficult to manage even in small amounts.
For example, a “dirty bomb” made by packing coal ash around conventional explosives would be far less effective than one made from spent nuclear fuel.
