    Bullshit. Nuclear waste (more precisely, spent fuel that can be reprocessed for new fuel or other useful radionuclids) is the only waste we have actual good solutions for. It’s not an engineering problem, we know very well how to safely dispose of the small amount of ultimate nuclear waste.

    All the other waste, including waste from producing new and retiring old solar panels and wind turbines, basically just gets thrown into the landscape with no containment whatsoever. And some of that stuff is toxic, some will never degrade (plastics used in composite materials the wind turbine blades and towers are made of).

    Plus, if you only used nuclear energy throughout you life, the amount of ultimate waste can literally fit into a coke can. That’s how efficient and energy dense it is.

      What’s this amazing waste disposal method you’re convinced exists? Last I checked, the waste will still be around for at least a millennia and the only process we have to deal with it is bury it in a hole with a sign that says ‘BAD’ in a way we hope future generations can still interpret.

          “There would still be waste that would have to be disposed, but the amount of long-lived waste can be significantly reduced,” Gehin said.

          “Significantly less” is not defined. Is it 80% less? 50? 30? 10? The guy they’re quoting, who has a vested interest in selling us this tech, sure doesn’t say and uses the qualifier ‘can be’. In fact, I can’t seem to find that information anywhere, let alone this article.

          Irregardless, there’s still waste that will take hundreds (thousands?) of years to decay. The solution is renewable energy.

            You’re obviously not willing to change your mind, so this will be my last response. Googling “breeder reactor” will show you plenty of peer reviewed papers and findings from past experimental reactors that can answer your questions.

            Apart from that, the point of the technology is obviously not to replace renewables, it’s to

            1. Phase out coal and oil as fast as possible.
            2. Get rid of the nuclear waste we already accumulated (by turning it into energy).

            Especially point 2, you are obviously and rightfully worried about nuclear waste - breeder reactors are the solution, the only one we currently know of. What else do you suggest we should do with that waste? Store it for millennia?

              It’s not that I’m not willing to change my mind, it’s that I’m hugely suspicious of the recent push for Nuclear. Energy companies dumped massive amounts of money into the technology and want to see a return on those failed investments. So I am skeptical that there’s not some astroturfing going on.

              That said, when I was doing the research, I was looking up Fast Fusion, not Breeder Reactors so I’ll look into it.

              Also, your point about using nuclear to phase out of coal and into renewable has merit, but I think there’s a danger that we get stuck on nuclear as it becomes easier/cheaper than coal and so development in green tech, like batteries, languishes for another four decades or whatever.

              Anyways, I’ll look into breeder reactors and, who knows, maybe have a change of heart (maybe).

      We already have more nuclear waste than we have capacity to store. And we arent reusing that nuclear waste. If you wanna become a nuclear engineer and get them to start using it please do, but right now the nuclear waste plan is to bury it for many millenia

            That’s precisely where they go—landfills. They’re made of non-recyclable glass fiber-plastic composites that won’t degrade for millions of years.

              Landfills arent underground, and theyll break down within a millenia. Well the plastic anyway. Then youre left with recyclable glass if it isnt crushed into sand first

                Landfills not being underground is even worse (but normally they are buried under soil when they go unused).

                While the plastics degrade mechanically, being reduced into small particles, chemically they are not. They just turn into microplastics which I’m sure you’re aware is a huge problem.

                With the small amount of ultimate nuclear waste that cannot be reprocessed further, the solution is simple: drill a km deep shaft into the bedrock, place them at the bottom, fill the shaft with rubble and cement. Done. No-one’s going to accidentally dig them up and they pose absolutely no threat to anyone. The finns are doing something like this as we speak.
