2) All posts must end with a '?'
This is sort of like Jeopardy. Please phrase all post titles in the form of a proper question ending with ?
3) No spam
Please do not flood the community with nonsense. Actual suspected spammers will be banned on site. No astroturfing.
4) NSFW is okay, within reason
Just remember to tag posts with either a content warning or a [NSFW] tag. Overtly sexual posts are not allowed, please direct them to either !asklemmyafterdark@lemmy.world or !asklemmynsfw@lemmynsfw.com.
NSFW comments should be restricted to posts tagged [NSFW].
5) This is not a support community.
It is not a place for 'how do I?', type questions.
If you have any questions regarding the site itself or would like to report a community, please direct them to Lemmy.world Support or email info@lemmy.world. For other questions check our partnered communities list, or use the search function.
6) No US Politics.
Please don't post about current US Politics. If you need to do this, try !politicaldiscussion@lemmy.world or !uspolitics@lemmy.world
7) No Hit-and-Run questions.
Please don't delete your post for no apparent reason. If you plan on deleting a question later, say so in the post, or if you feel that you have a good reason to remove it, message a mod beforehand. It's not fair to the ones who took their time to answer, and it's not in the spirit of the community.

It's great and we should have more of it.
Unjustified fears of it blowing up and destroying the world are ridiculous and overblown, especially given modern advances in reactor design and safety. Nuclear waste isn't really an issue, so much as it is an issue of bad policy based on fear mongering about waste being stolen and turned into nuclear weapons/dirty bombs. Which has never happened... it's utterly stupid that due to these stupid fears we don't re-process fuel, which would reduce it's volume by 80%.
There are 431 reactors, and 360 of them are based on 1960s technology, designed and built mostly in the 1970s. They are 50+ years old. Thanks to Chernobyl, reactors are basically stuck in time. Esp when you realize that non-nuclear plants only last about 30 years before they are replaced
There are only 4 Gen 3 reactors in service, and 2 gen 4. Why we don't have 200+ gen 3/4 reactors is... insane. We just keep re-fueling the less safe Gen 2 reactors.
But this is generally just a problem with all our infrastructure in the developed world in general... we don't renew or upgrade it... we just keep patching it and then we wonder why everything is so shitty and inefficient... because we refuse to actually upgrade things in a real way
There is no point in using a technology that is only as profitable as it is due to subsidies and that generates tons of dangerous waste that we have no proper storage strategy for, when we could just use regenerative energy sources with basically no side effects and build a much more resilient power grid in the process.
It takes 10 years minimum from design to build out for a nuclear project, so that lines up pretty well with the end of the cold war once the US didn't need more nuclear material.
How is the waste not an issue? I have never heard the argument of it being stolen to be honest. Here in germany the problem with the waste is, that there is no good place to put it (though this is partly a political problem)
in the USA they won't re-process fuel because of fears it will be stolen and turned into weapons. so we have 5x the waste volume than other countries where fuel is re-processed.
also we won't use breeder reactors because of this, which are more efficient and produce way less waste than normal reactors.
yes, it's all political problems. people are ignorant and angry and fearful and won't let nuclear power problems be resolved because they don't understand solutions exist and if you try to educate them they refuse to learn because they want to cling to their fears and emotions about it. a lot of political problems are like this. we have active solutions for many social problems, but people refuse to allow them to be implemented because of fear and delusional belief.
Only ~3% of nuclear waste is really dangerous, that's the spent fuel rods. The majority of "nuclear waste" is stuff that was in proximity and contains intermediate to low levels of radioactivity. It's obviously not great to injest or spend all your time around, but it can be safely stored almost anywhere as it's mostly only emitting alpha and beta particles.
So what about the dangerous stuff like fuel rods? Well, if you took all the dangerous waste nuclear power ever created and piled it in one place, it would cover a football field and be stacked 3 meters high. That sounds like a lot, but remember, that's is ALL the dangerous waste nuclear power has EVER produced. Compare that to literally any other form of energy production, including solar and wind, and the footprint from nuclear is laughably, almost unimaginably, small.
I think you have no clue how dangerous that waste is. There is literally no way to store it in a volume like you described because of all the heat it generates. If it gets distributed for some reason, it could contaminate the entire planet.
Also, other nuclear waste is not not dangerous. You have to store it in a way that it doesn't pollute water, for example. That is a much harder problem than you might think. Here is an interesting read for you:
https://en.wikipedia.org/wiki/Asse_II_mine
eh, i'm 50% talking out of my ass here, but the waste is actually not a problem. if we wanted to, we could use it again to extract even more energy out of it ... problem is that that's currently not economical.
"using it again" would require special reactor designs that can stimulate the material to do extra-decay. which causes the extra cost.
That is more like 99% out of your ass.
Because the amount of waste we've created is really quite small. Per the US DoE:
There are ways we can repurpose or reuse spent nuclear fuel. I don't know a lot about this so I won't get into it, but even if we chose to do nothing with it and just bury it, we know enough about geology that we could stick it into some bedrock that will be stable for the next 500 million years.
But long term storage also isn't easy. Maybe it's less of a problem in the US (you've got a lot more free space where no one lives) but it has to be made sure that it does not contaminate the surroundings, even in thousands of years and more. Another (as of yet unsolved) problem is far more human. How do we mark those places, if at all. See this article https://en.wikipedia.org/wiki/Long-term_nuclear_waste_warning_messages
Just hollow out a mountain, like the US did with Yucca mountain, plenty of storage (if you're politicians let it be used for its purpose) that is pretty easy to secure for centuries (and after that probably pretty easy as well). Assuming you close it up well when full, even future historians probably will have an idea that it's dangerous by the level of difficulty to just get into it.
Not trying to discount the issue, just point out that there generally are solutions to the issues around nuclear waste, just that politicians have mucked it up quite a bit in the past (especially in the US).
Until Harry Reid does everything in his power to shut it down like an asshole
The idea in germany are old mines, we already have some "temporary" solution (an old saltmine) but there are some problems with it. Understandably there is a lot of nimbyism around the permanent storage, which makes finding a good spot a lot harder
which, as we all know, implies that it will never happen ...
actually, after reading through your whole comment, it has a few issues:
Yes, you're right, nuclear power plants are safe as long as nobody in engineering royally fucks up. But, as we all know, engineers never fuck up and forget an important detail ... (/s)
This sounds like a popular thing to me ... people think that replacing old things will make them better / more efficient. When that is simply not true. Banks, for example, still use programming language from the 1960s. Why? because actually it turns out that that stuff just works. Meanwhile newer languages each introduce their own new kind of problem. The same phenomenon happens in many cases. I was told that airplanes do the same, using flight control software from 20th century ... for the same reasons. "newer" does not imply better.
