Loads of people love to pretend an NPP is just a hut with a magic gem inside delivering an endless amount of power for free. In reality they are huge, highly complex, high-security facilities that take decades and billions to build and need to be operated and maintained by loads of highly trained staff in 24/7 shift operations. This isn’t to downplay their merit of providing CO2 emission free power, but for the love of god please appreciate the enormous effort and expense this is achieved with, especially when comparing it to renewables.
From what I understand, the costs and time needed to build a reactor would be far less if the constructions crews actually had experience building them.
Things that don’t exist yet aren’t a solution for problems we have now.
It’s not like we could now just build a thorium reactor that makes economic sense without decades of serious prototyping. And by that time we might have found that there are more pbolems with it than we thought.
I mean, China is doing it right now, and we’ll have answers in a lot less than decades.

If the TMSR-LF1 proves successful, China plans to build a reactor with a capacity of 373 MWt by 2030.
Not sure which unit MWt is. Anyway, let’s see how far they are in 7 years.
Strange source aside I’ve been hearing were on the edge of a breakthrough for thorium reactors and cold fusion for 40 years now.
If China had it working already then we would have heard it a lot louder from them.
Don’t forget about the environment cost of extracting unprocessed uranium ore.
Unfortunately renewables have nasty costs like this of their own.
Solar panels require a specific grade of silicone as a rare(ish) raw material input that requires extraction and heavy processing. Wind turbines don’t really use anything that is not readily available (steel, aluminum, fiber glass, etc.)
The technology to recycle solar panels still needs to be developed. The technology to recycle solar panel blades exists, but has not scaled up yet.
I’m not saying solar/wind have no material cost. I am saying the process for refining uranium requires extracting a lot of uranium ore.
You don’t actually need that much uranium though. Yeah it’s a big operation, but that stuff goes a long way.
Even wind power needs rare earth elements like neodymium and dysprosium, which pretty much only come from China and the mining operations there are kind of horror shows.
Hell yeah they bring high quality jobs as well as clean power
Sighs in thorium LFTR reactor noises.
That technology is nowhere near mature enough to provide a solution to the mentioned problems in the next decade or two.
Well of course not, now. I never said it would fix the now problems we face. Had we started in the 1950s, or even the 70s, the impact of climate change would have been negligible and likely mitigated entirely by changes to society that we can’t possibly speculate given our current world. Unfortunately, money and greed played yet another part in destroying our futures by those who won’t be around to see what they’ve done or simply don’t care.
It’s almost like many things operate exactly like that but don’t have people spreading disinformation or fearmongering to the point where people are so pants shittingly terrified of them they won’t even consider it.
Yeah, fossil fuel companies have spent the last 70 years propagandizing against nuclear because it’s their largest threat.
Sure, but hopefully you have no trouble believing that simultaneously, nuclear power companies and governments wanting to use nuclear, despite the risks, have been propagandizing for nuclear.
Pro-nuclear folks are often completely unaccepting of there being risks and externalized costs, which feels to me like they’re subject to propaganda (notwithstanding that I’m likely subject to different propaganda).
Sure, let’s pay private corporation billions in subsidies by handling their waste and have more centralisied and expensive energy production. Oh and trade dependencies due to uranium
The most recent nuclear reactor built in the US bankrupted Westinghouse and is set to raise utility rates. Oh, and it’s $17 billion over budget and 7 years late.
Yep. Yet, Climate scientists still believe that we need to rely on a combination of nuclear and renewable energy in order to combat climate change. This tells me we’re bad at it, and we need to get better at building and maintaining nuclear plants.
Nuclear solves one of the biggest issues with renewables because the energy output can be adjusted.
This in turn means that you need less energy storage capacity in order to supplant existing technologies.
Honestly I’m just happy we’re moving away from fossil fuels.
Nuclear is a great supplement to wind and solar PV.
Especially when the share of renewables get close to 100%.
Going from 85-90% to 100% imply to almost double the capacity of renewables energy available, even with batteries and thermal power stations as a backup.
On the other hand having 10-15% of nuclear really helps to stabilize the grid and lower the need to oversize the renewables power production.
Some of the smartest people in the world have been working for over half a century to get better. And yet it’s still getting more expensive to build them.
Maybe it’s just hard and a dead end. Like the paddlewheel or dirigibles. At the time they felt like the future but there were unforeseen problems in scaling them up to meet expectations, and we found better, safer ways of doing the same thing.
Small nuclear reactors seem to work pretty well. Using them for deep space or disaster response would make sense. Just park a Seawolf off the coast and hook it up to support the grid.
It is not hard due to lack of knowledge, it is hard due to politics, and the fact that they require trained / skilled builders and operators.
So it’s a cold start problem. As we aren’t making many, we don’t have much trained staff.
Haven’t we been building reactors for decades though? Are all those guys dead along with the COBOL programmers?
We have documentation, but you.need to have construction crews working to keep the specific routines and needs sharp.
Sure they have people “ready” to work on such projects but it takes significant time to tool and train up, even for the “ready” folks because they don’t do these jobs often.
Are they significantly different from normal specialized plumbing/electrical/heavy construction work? Weird, complex things get built all the time these days and I’m curious how much different pouring concrete for a reactor is compared to, say, a bridge.
If we were talking about naval reactors you’d have a point.
But this is what I was talking about in another post: Maybe big reactors are a bad idea? Maybe there are issues with getting them to utility-scale that, like blimps, makes them the less ideal solution for most applications?

Huh, it’s true. sauce
Great article, the one time a corporation actually loses money from cutting corners, and it’s because government inspectors kept catching them in the act. Hilarious!
Canada and Australia are notoriously unreliable trade partners. (/s)
Sure. And by the time we have one reactor finished in 20 years and 200% over budget we’ll be completely powered by renewables in that time.
This is the real problem. We shouldn’t shut down existing nuclear plants, but adding more in a period when renewables are advancing at a tremendous pace is just… not sensible.
Especially as the cost per megawatt of renewables is dropping precipitously and the cost of nuclear is actually going up
Nuclear powered wind farms, to combat natural cyclones with counter spinning cyclones intensively farmed
I find it refreshing to see a bunch of realistic cost comparisons here whereas on Reddit, anti-nuclear voices get downvoted for being “outdated”.
Thorium is abundant and a byproduct of rare earth mining. It’s also what the moon is mostly made up of, so our energy requirements on the moon could use locally mined sources for power generation making moon bases much cheaper to operate.
A Liquid Fluoride Thorium Reactor, or LFTR, not only can’t melt down, it can be smaller and require less staff to manage, requires no external cooling so it can be built anywhere, and cannot be used to make bombs. It’s also not radioactive by itself.
In the 1940s, both uranium and thorium were looked at as potential fuels for nuclear energy, but you can’t make bombs with thorium, so the US went with uranium. LFTRs create no nuclear waste, can be used to burn existing nuclear waste created by other nuclear energy processes, extracting more energy from our giant stockpile of unusable nuclear waste, and if the plant loses power, which is only needed to keep a frozen plug frozen, excess fuel melts and the empties into a reserve tank. Most rare earth mining companies don’t even know what to do with the thorium they mine, so they store/stockpile it in hopes of future uses.
It simply baffles my mind that this isn’t even on the table for potential, near limitless energy generation in addition to, or in replacement of, wind and solar green energy. The nuclear fearmongering has tainted the idea of safe nuclear power generation to the point that I suspect many of you have never heard of it. We literally have the answer to energy needs for the entire world, using greener production, but since it’s new and would require billions to fund and start, it hasn’t been considered until recently.
If billionaires really wanted to help humanity, rather than simply saying so for PR and launching their cars into space or creating flamethrowers, this is an investment that, while not as quick to return gains, would be lucrative, forward thinking, and beneficial enough to help all of humanity and this planet. And they could have started in the 50s when the government played around with a test reactor for proof of concept and proved it worked. Imagine a timeline where capitalism and greed weren’t a thing and climate change wasn’t even an utterance outside of explaining why Venus is so fucking hot!
and cannot be used to make bombs
That is not true. Scientist even argue if LFTRs are a powerful way to create Uranium233.
LFTRs create no nuclear waste
Also not correct. Where did you get your facts from?
That is not true. Scientist even argue if LFTRs are a powerful way to create Uranium233.
I cannot find information online about scientists saying anything of the sort, but I don’t feel like logging into my work VPN to access the pay-walled articles that might have that info. The amount of time required to get enough material for any significant bomb, at least with the information I can find, makes it impractical for that purpose so I stand by my statement.
Also not correct. Where did you get your facts from?
I thought about including little to no waste in there, but opted to put none, because yes, while it still creates some waste, it’s significantly less waste, that becomes safe after a few hundred years compared to the several thousands of years that current nuclear waste takes to become safe.
My message is still correct, which I suspect is why you only selected two sections from the entire thing – where I over-generalized a statement of fact – as arguments to negate the entirety of my reply.
Current NPP are extremely, almost comically inefficient and wasteful. The material is harder to get, harder to handle, less fuel-dense, and the waste produced creates a hazard that spans hundreds of human lifetimes. We’ve known about thorium for power generation for decades, but greed and “national security” prevented us from acting on it. Coupled with the confusion and misrepresentation of nuclear power as “dangerous” in the eyes of the general public, and we’re now on a collision course with a potential wasteland of a planet.
But hey, don’t let a little mistype or over-generalization stop us from knowing options that have largely been withheld or lumped in with more dangerous forms of the same power generation.

I see you everywhere. I’m your secret friend. Ok, not so much a “secret” friend… stalker! That’s the word!
Anyway, can you crosspost this to one (or more) of
I haint giffured out xposting on Lemmy, or if it’s even a thing.
They’d probably appreciate it.
With the effort you put into this post, you could have just done that posting yourself.
What, and steal their glory‽ Also, I don’t know if there’s no ability to crosspost in Lemmy, or my client just doesn’t support it. E.g., I recently discovered that there’s an “edited” icon in some clients that I don’t see in Voyager.
Anyhoo, OP said they don’t play Factorio, so I just might. I juuuust might.
Plus you should be using that time in other ways, that factory isn’t going to grow itself
Hey, so that was you hiding behind the bushes!
I haven’t played Factorio and wouldn’t want to be a poser, but you’re welcome to repost or cross post wherever! I didn’t make this one.
I vote we blow radioactive material around with giant fans. That should solve some of our energy problems.
Nuclear power isn’t renewable. Joule for joule, our reserves of nuclear fuel and petroleum are comparable. It’s a decent bandaid, but between the finite fuel supply and the nuclear waste problem it’s hardly the future and should be used as sparingly as needed to get us off of oil and onto renewables.
How about not polluting the ground water for millenias?
that is like 100 nuclear power plants worth
