A lot of comments here are displaying their ignorance of nuclear technology.

Keep eating up the oil company talking points, I guess. "hey guys remember those nuclear meltdowns from outdated reactors that had all kinds of things going wrong because of poor design and decision making, most of which is no longer an issue? Yeah things blow up so better keep chugging away at those fossil fuels while we sabotage any investments into renewables"

I mean goddamn, the "worst" disaster in the USA was a big nothing burger that was sensationalized by newspapers that knew how to sell a headline, and oil companies that knew how to leverage any sort of negative press to their advantage.

When the fallout from nuclear disasters doesn't come close to the amount of radiation out off by burning and refining fossil fuels, there is no argument.

the "worst" disaster in the USA

The 3-Mile Island incident hit two weeks after The China Syndrome hit theaters. (A movie about a runaway nuclear meltdown.)

Otherwise the story would have been, "A tiny poof of radioactive steam got loose, everything was handled quickly and perfectly, no big deal, and back to you Tom (Brokaw).

[–] x00z@lemmy.world 58 points 1 day ago (3 children)

Yeah things blow up

I would stop them right there and ask when the last oil spill was.

It was last month. https://en.wikipedia.org/wiki/List_of_oil_spills

[–] Korhaka@sopuli.xyz 24 points 1 day ago

Even without oil spills. The fossil fuel method of dealing with waste is to vent it into the atmosphere. Nuclear only does that when something goes very wrong, and even then it causes significantly fewer fatalities.

You could have a Chernobyl every single day and still kill fewer people than coal and oil.

Why do you think that those against nuclear energy are for fossil fuels? My building has solar panels, and backup power comes from either wind turbines or the hydraulic dam down the river.

[–] SARGE@startrek.website 8 points 1 day ago (5 children)

The safety aspects alone SHOULD be enough to convince people, yet here we are.

The difference between nuclear-power- related disasters and fossil fuel related disasters is astronomical.

And honestly the amount of radioactive isotopes that get spewed out from burning coal day in day out for decades on end absolutely dwarfs the amount of radioactivity released from nuclear disasters.

Yep. So much of this shit from "environmental activists" that have no fucking clue how any of this works. It's been shown time and time again that nuclear is the answer for base load energy requirements with minimal environmental impact.

You lost me at this:

For this transmutation Transmutex proposes using a particle accelerator, probably because the promoter of the idea is a former engineer at CERN,

Yeah it's definitely not that the only reliable method we have of knocking protons off of atoms involves either a nuclear reactor or particle accelerator, dude is just bringing his old job with him cause he doesn't know any better. Right.

[–] Monument@lemmy.sdf.org 8 points 1 day ago* (last edited 1 day ago) (1 children)

No, as non-experts, we must dismiss the knowledge of experts because their approach is not non-magical pseudoscience bullshit that consists mostly of evocative imagery.

I don’t need no boring particle accelerator! I want an atom smasher that’s been combined with cutting edge AI and the latest in superconducting magnet technology to tame matter down to the subatomic level so it can shoot a laser made of protons into radioactive materials to fundamentally alter its elemental properties so it no longer emits ~(as~ ~much)~ radiation!

[–] Libra@lemmy.ml 5 points 19 hours ago

Indeed, this is like the techbro approach to nuclear reactors, which seems like the worst of all possible worlds: all buzzwords and bullshit hiding barely-concealed scams about shit that can absolutely kill you.

[–] Katzimir@lemmy.dbzer0.com 27 points 1 day ago (1 children)

Transmutation is not new technology. It has always been too expensive to be used on an industrial level. I dont think that has changed. also by no means does it reduce the cost of dismantling and securing npp sites. Dont be fooled :/

[–] sit@lemmy.dbzer0.com 8 points 1 day ago (1 children)

You seem to know stuff.

Why don’t we take “depleted” fuel and use it in a low power atomic power plant? The rest radioactivity can be burned off just like their main radioactivity right?

There should be a solution to burn them further down and generate electricity with it.

Or do they lose the properties to burn them?

Thanks

The reactors we use now can't run on depleted fuel. It's true that like 90% of the uranium is still present in deleted fuel but that's not the problem. The problem is the build up of fission products. The fuel itself is essentially a ceramic pellet in a metal tube. As it gets "burned" some of the atoms in the fuel split into new smaller atoms. Specifically some that are "poisons" and some that are gases. The poisons absorb neutrons much more easily than the fuel atoms, stopping the chain reaction. And the gases create pressure inside the fuel pellet. If enough gases build up this can cause the pellet to crack, releasing them into the metal tube. Now you have one less barrier to releasing radioactive material and your pellet isn't in the shape it's supposed to be anymore making it harder to know how it will react.

So we can't use them in current reactors, what about "low power" reactors? This is a problem of economics. Depleted fuel is hot, but not hot enough to quickly boil water and make steam. It's like asking why don't we power our house off all the free heat coming off a person all the time. The temperature difference and heat output is just too low to be useful in any but the smallest niche application.

So how do we deal with the depleted fuel? We reprocess it. Break down the fuel and dissolve it in acid so you can recover all the useful uranium to make new fuel. The leftover radioactive material can then be turned into glass and safely stored or you could feed it into a different type of reactor that "burns" the waste turning into something that only needs stored for 200 years instead of 20,000 years. All this has been well known and understood since the 80s but politics consistently gets in the way of actually doing anything.

Is there any source with any real information? This one is just bullshit.

[–] richtellyard@lemmy.world 11 points 1 day ago* (last edited 1 day ago)

Here's a more measured take on it, particularly the Update section - though it's written by the company creating the long-term waste repository in Switzerland so there's some obvious bias.

It appears the modeling/simulation code Transmutex developed is heavily based on the open-source Geant4 toolkit.

[–] jagged_circle@feddit.nl -3 points 13 hours ago (1 children)

Yeah, no thanks. Solar panels.

[–] HikingVet@lemmy.ca 1 points 5 hours ago (1 children)

Hope you like lithium mines.

Water is the best battery. Hydro at night, solar and wind at day.
