Rules:
-
Rule 1: posts have the following requirements:
- Post news articles only
- Video links are NOT articles and will be removed.
- Title must match the article headline
- Not United States Internal News
- Recent (Past 30 Days)
- Screenshots/links to other social media sites (Twitter/X/Facebook/Youtube/reddit, etc.) are explicitly forbidden, as are link shorteners.
-
Rule 2: Do not copy the entire article into your post. The key points in 1-2 paragraphs is allowed (even encouraged!), but large segments of articles posted in the body will result in the post being removed. If you have to stop and think "Is this fair use?", it probably isn't. Archive links, especially the ones created on link submission, are absolutely allowed but those that avoid paywalls are not.
-
Rule 3: Opinions articles, or Articles based on misinformation/propaganda may be removed. Sources that have a Low or Very Low factual reporting rating or MBFC Credibility Rating may be removed.
-
Rule 4: Posts or comments that are homophobic, transphobic, racist, sexist, anti-religious, or ableist will be removed. “Ironic” prejudice is just prejudiced.
-
Posts and comments must abide by the lemmy.world terms of service UPDATED AS OF 10/19
-
Rule 5: Keep it civil. It's OK to say the subject of an article is behaving like a (pejorative, pejorative). It's NOT OK to say another USER is (pejorative). Strong language is fine, just not directed at other members. Engage in good-faith and with respect! This includes accusing another user of being a bot or paid actor. Trolling is uncivil and is grounds for removal and/or a community ban.
Similarly, if you see posts along these lines, do not engage. Report them, block them, and live a happier life than they do. We see too many slapfights that boil down to "Mom! He's bugging me!" and "I'm not touching you!" Going forward, slapfights will result in removed comments and temp bans to cool off.
-
Rule 6: Memes, spam, other low effort posting, reposts, misinformation, advocating violence, off-topic, trolling, offensive, regarding the moderators or meta in content may be removed at any time.
-
Rule 7: We didn't USED to need a rule about how many posts one could make in a day, then someone posted NINETEEN articles in a single day. Not comments, FULL ARTICLES. If you're posting more than say, 10 or so, consider going outside and touching grass. We reserve the right to limit over-posting so a single user does not dominate the front page.
We ask that the users report any comment or post that violate the rules, to use critical thinking when reading, posting or commenting. Users that post off-topic spam, advocate violence, have multiple comments or posts removed, weaponize reports or violate the code of conduct will be banned.
All posts and comments will be reviewed on a case-by-case basis. This means that some content that violates the rules may be allowed, while other content that does not violate the rules may be removed. The moderators retain the right to remove any content and ban users.

Nuclear energy produces the worst toxic waste guaranteed, and can and has a record of leaking a lot of radioactive material.
When wind and solar are ready alternatives it just makes no sense.
To preface, i dont support coal at all, its way worse than nuclear.
If i remember right, the coal thing was measuring radioactivity in the air around coal and power plants. Thats not the nuclear waste im talking about. Spent nuclear fuel is dangerously radioactively for longer than the whole of human civilization. It puts plastic's lifespan to shame. Its no where on the scale of volume as fossil fuel waste, but pound for pound i believe it is the worst substance we can produce.
If you remind me later today ill explain how energy storage is easily solvable, itll take longer than i have now
The air radiation thing is misleading, saying the area around coal plants is more radioactive than nuclear plants isnt saying anything, because the air around nuclear plants isnt radioactive.
Most US nuclear waste isnt buried, because we dont have anywhere ready to. Its stuck in on site storage. It might be safely stored for now, but that waste is gonna accumulate like nothing before because of how crazy long it remains dangerously radioactive. Nuclear waste produced 10000 years from now is still gonna be competing with nuclear waste produced today for room to be safely stored.

The company Moltex Energy claims they can “recycle waste from existing nuclear power stations, and use it to produce more clean energy”. If true it could solve several problems at once.

Inaccurate. To take it back to basics:
Radioactive material radiates, because it decays. The more it radiates, the faster it decays. The highest level radioactive material from nuclear fission reactors has half-life measured in decades (30 years), that is, half of it will decay in that time. It does NOT take thousands of years. Conversely, the long-lived isotopes radiate much less, thus are easier to store and process.

I dont think you read your source quite right. The classification for high level waste is the most radioactive spent fuel, but it is absolutely not safe after a few decades, it decays into still dangerously radioactive isotopes. Maybe you read the part about the dry casques being rated for 40 years but keep reading. They are a temporary solution, and the waste still needs to be buried for tens of thousands of years. Which is a big problem right now because, from your source
@blazera
I did not say it was safe, I said after a few decades is far easier to process. It does not remain "crazy" high radioactive for thousands of years - that is pure hyperbole. The chart attached illustrates radiotoxicity if ingested - and no one advises anyone to eat nuclear waste.
Ps. There is a country which has solved long term storage. Guess where I live.

@dilmandila
And what you said was still wrong, it still remains dangerously radioactive, and must be stored for tens of thousands of years. Like, youre not gonna find me a source saying this shit doesnt need to be stored for tens of thousands of years.
Alright its later today so heres how renewable energy as a baseline supply works. We actually already have a working example of it, hydro electric. Renewable energy thats used as baseline. When you think energy storage i think most people think of batteries, but theyre mostly suited for mobile energy storage, like cars and handheld devices. For utility power we have much more scalable, and simpler energy storage. For hydroelectric, they take excess electricity generated, and power pumps to pump the water back uphill, to use for later demand. Its physical energy storage. You can power a motor to lift a weight and pulley system with excess energy, then run it in reverse as a generator for demand. This is basic engineering, and its as scalable as you need it.
Right, pumped storage hydro electric was an example of renewable electricity being baseline load. I gave a different suggestion for wind and solar storage if you dont have a good location for pumped storage.
Oh god lifting and dropping a weight near impossible to implement? You cant mean that, you cant be that simple minded that you cant imagine an electric motor winding a chain hooked up to a pulley lifting a stone block. What part of this process is unfathomable for you?
It is already implemented, i gave you an example of it being implemented, its an everyday fact of life that we use electricity to lift enough weight uphill to cover times of demand surpassing immediate supply for massive regions.
I will reiterate, that it is an amount of weight lifted that we already achieve, everyday to power entire utility areas. And Im tired of these strawmen. You know what would be an even more impressive feat? Building a nuclear plant to power your own house alone. Building one power plant to power the entire nation, from any source. We're not building to power one home, we're not building to power the entire nation at once.
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.
Last you checked? When was that?

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
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?

Way ahead of you this time, bot. Keep fighting the good fight.
Can't you chuck it back into a reactor and reuse it that way, to help reduce the radioactivity, and get more power back out of it?
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
Please don't down vote just because you don't agree. Please please don't let this be reddit again
I'm not downvoting because I don't agree, I'm downvoting because the statement is factually inaccurate - coal power produces more radioactive waste than nuclear power does.
But isn't the whole point to have a discussion, instead of hiding (related) opinions?
I'm not here to discuss oil and gas industry funded propaganda and disinfo.
what's wrong with downvoting because I don't agree? Isn't that the whole point of downvotes?
Not really. Ideally people should only downvote when something isn't contributing to the conversation, and if you disagree you reply to it and voice your disagreement.
But people are going to be people, so it eventually always turns into a "disagree" button, cause it's much easier than commenting.
Who decided that's how downvoting should be used? There is no official rulebook (especially on the fediverse), and etiquette is decided as a group, but there isn't clear consensus on this.
The technical function of the downvote is to push the comment down far enough that people won't see it. And so people will continue to use it as a way to communicate that they do not approve of the comment. And telling people to stop downvoting comments they don't like is trying to enforce a rule they never agreed to.
I was adding context to the "downvote button is a disagree button". We're in complete agreement.
how do you determine if something is not contributing to the conversation though?
For example, if I made a pro vaxx post and someone posted some anti vaxx propaganda, would you downvote it?
Isn't that just a soft 'rule' established via Reddiquette?
It’s not a question of nuclear vs wind/solar. It’s a question of running baseline power from nuclear or coal/gas, which kill people every single day. It just doesn’t make the news.
Wind and solar are not magic bullets. Better than fossil fuels, yes. But they come with their own "the ocean is too big to pollute" type quagmires that we overlook when deployed on the small scale. The most basic example: solar panels are dark in colour -- deploying a few of them is trivial, but deploying a lot of them over time will cause the average albedo of the earth to change, heating it. This won't be a problem today, but would be in a century. Etc. Still better than greenhouse gasses though.
Nuclear likewise has issues. You're just straight up adding heat to the system. And depending on the reactor design, you have waste. But it's a huge improvement over fossil fuels.
Solar panels arent typical light surfaces, they dont convert all the light absorbed into heat, their whole point is they convert some light absorbed into electricity.
Add onto the fact black is already a popular roof color.
