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.

do not let "perfect" be the enemy of "good enough"
edit: quick addendum, I really cannot stress this enough, everyone who says nuclear is an imperfect solution and just kicks the can down the road -- yes, it does, it kicks it a couple thousand years away as opposed to within the next hundred years. We can use all that time to perfect solar and wind, but unless we get really lucky and get everyone on board with solar and wind right now, the next best thing we can hope for is more time.
I completely agree with everything you said except for ONE little thing:
You are grossly misrepresenting how far that can is kicked down, for the worse. It doesn't kick it down a couple thousand years, it kicks it down for if DOZENS of millennia assuming we stay at the current energy capacity. Even if we doubled or tripled it, it would still be dozens of millennia. First we could use the uranium, then when that is gone, we could use thorium and breed it with plutonium, which would last an incomprehensibly longer time than the uranium did. By that point, we could hopefully have figured out fusion and supplement that with renewable sources of energy.
The only issue that would stem from this would be having TOO much energy, which itself would create a new problem which is heat from electrical usage.
Then you just move the planet slightly further away from the sun! Problem solved!
No man you gotta move the moon closer, since it's cold
I like the cut of your jib, sir.
Some of the biggest blunders of all time come across because too many people let perfect be the Nemesis of good
I really cannot stand that phrase because it’s commonly used as poor rationale for not favoring a superior approach. Both sides of the debate are pushing for what they consider optimum, not “perfection”.
In the case at hand, I’m on the pro-nuclear side of this. But I would hope I could make a better argument than to claim my opponent is advocating an “impossible perfection”.
But that is exactly what's happening. People are pretending like the alternative to investing in nuclear is living off 100% renewables from tomorrow.
Buying time isn't a great argument for nuclear when it takes so much longer than wind or solar to build a plant - median time of 88 months to build a nuclear plant compared to 8-14 for solar.
People will get on board when they see the cost per kwh.
So best time to do it was 88 months ago... What the next best time to do it?
Nuclear is most of the time over budget and planning. That's a fact.
Over budget and over planning is bad.
...but also irrelevant - I gave the average real world delivery times.
Which isn't unusual for large construction projects. Nuclear is biggest cost problem is that each power plant is essentially a mega civil engineering project. They require cooling ponds, cooling towers, huge reactors, turbines, and radiation shields.
All of which are fairly large structures that have to be built to pretty high tolerances and have little room for construction defects which are very common in the industry. I work in construction and I can tell you that the majority of construction projects, whether they are an office building, a highway or a bridge run over budget.
There are always going to be factors outside of the control of the design team and the developer. Contractors may run out of labor, supply chains may have many years to complete some of the equipment and these issues compound the schedule which is already very complicated. Do we have an even discussed the expanded and politicized planning and safety rules and certifications that a new nuclear plant is going to need to follow.
I think the solution for micro reactors is pretty intriguing, except we need lots of power not small amounts of power. But a mass-produced reactor that rules off of an assembly line in a factory is likely to be on time and on budget because they can correct for for the problem of building things in the field. It's really hard for people to fabricate complicated machines when they're being rained on in the middle of winter during a storm.
But this is my argument against those who complain about Solar and Wind -- those won't kill you or destroy a location for hundreds of years if they break down and once they're installed they don't have to be fed by more mining, or anything else. Just wind and sun.
And maintenance, it apparently takes quite some effort to keep those running
Funny you say that. Solar and wind each have more human deaths per kWh than nuclear.
Worth mentioning that fossil fuels blow those numbers completely out of the water, though.
Where are you getting that from?
https://ourworldindata.org/grapher/death-rates-from-energy-production-per-twh
I was mistaken. Nuclear lays in between wind and solar.
The death rate for nuclear was mostly from Fukushima, where about 2,300 elderly people died from the stress of moving from their homes. But their houses were also wiped out from a 35 ft tsunami so...
Chernobyl and Fukushima didn't directly kill very many people. Only 1 person died from radiation at Fukushima.
From the author:
The problem with Nuclear's "good enough" is that Nuclear is currently worse than other technology we have in almost every way.
It is absolutely true that solar and wind are better because more money has gone into their research. But because of that, they are better options in almost all real world power situations.
The problem with focusing on nuclear is... why waste all that political capital just to spend 100x the money or more that you could spend to be 100% renewbles in the short term? The front-loaded TCO is the real issue with that one. If you wanna hit 0 emissions tomorrow with Solar/Wind, you're just paying the up-front costs, knowing there are per-year costs (still cheaper than fossil fuels) to keep it going. If you want to do the same with nuclear, you're paying for almost all of it out of the gate for 50 years worth. Suffice to say, that's a budgeting nightmare.
And what's left is space. Nuclear creates a lot of power in a small area. But wind and solar are both far more easily/efficiently integrated into the space we are already using.
No way. Batteries are expensive as hell. Solar+Battery is at best equal to nuclear in the current numbers. And probably worse overall... forget the actual damages as far as mining all the lithium and other rare metals.
You're in the green after about 10-15 years with nuclear. So I'm not sure why you bring this point up repeatedly. https://youtu.be/cbeJIwF1pVY?t=600
TCO shouldn't matter to stop climate change.
There's plenty of decommissioned coal/gas/oil plants that are perfect sites for nuclear. Ironically it costs more to clean up the radioactivity left behind by these plants than the nuclear plant will release in it's whole lifetime.
Batteries+solar runs $77/MWH with current technology. Nuclear runs $175/MWH with current technology (both of these numbers are TCO, not just running costs) 1 and 2. Months back I did a fairly exhaustive analysis on reddit. Wish I'd kept a link of that, but I cut and ran. More importantly, a nuclear plant is usually "locked in" to current efficiency for 50 years or more, where solar farms and battery farms can be traded up. By end-of-life, that nuclear plant will still be a $175/MWH-TCO plant, but could be competing against solar+battery in the order of $50/MWH TCO as large scale battery tech is skyrocketing of late.
I ended up anti-nuclear from a position of knowledge and research, not a position of "omg it's nuclear". I started pro-nuclear until I did the math a LOT.
Per Nuclear Power Economics and Project Structuring, the capital cost accounts as 60% of the total cost of ownership. Yes it's in the green (capital-wise), by year 10-15. But 60% of Every penny that needs to be spent on a nuclear plant is spent before you hit the "on" button. Solar plants go green in 5 years, but more importantly, you amortize the cost (and continue to do so) over the life of the plant. The latter is always more feasible for a large scale project.
Compare that to solar roofs, solar parking shades, windmills that can often be installed in "spare lots", etc.
EDIT: And to be clear, I'm not even saying there may never be an appropriate use for a nuclear plant in going green. There's just very few of them. Going solar in a big city is a custom gig, but dropping a nuclear plant in its outskirts, not so much. Luckily for me in the US, there's a whole hell of a lot of unused or unusable land just begging for solar plants.
According to the EIA.gov, nuclear is between 36 and $88 per megawatt hour for LCOE for advanced nuclear. Your numbers are way off.
https://www.eia.gov/outlooks/aeo/pdf/electricity_generation.pdf
Strange. I must be mis-reading your numbers, because the chart I'm reading on your link shows an LCOS/LCOE between $88 and $98... The numbers I was quoting was probably conventional nuclear, and that's a fair correction. I would really appreciate if you are able to address why my references disagreed with your reference, as I didn't come out with my numbers off-the-cuff. Is it conventional vs advanced nuclear, or is it a different measurement entirely?
Note also, however, that Advanced Nuclear still loses to Solar handily in every single chart presented in that document. In addition, none of that addresses the front-loaded cost of nuclear vs solar, which amounts to an entire order of magnitude.
And yet you made simple mistakes like assuming that nuclear reactors only last 40 years?
https://www.energy.gov/ne/articles/whats-lifespan-nuclear-reactor-much-longer-you-might-think
When your assumption is flawed by literally a possible 50% (or more) of the nuclear reactors lifetime your evaluation is useless. Your numbers are useless without evidence or citation especially when you make easily disprovable assumptions from the get go.
What magic technology have we invented? You realize that lithium ion batteries are 1980's technology right? We haven't made any significant advancements in battery technologies in decades. All we do is repackage it so we can charge/discharge them faster. That's not capacity.
Yes, that's what I said. Remember we're in it for long term solutions. Not bullshit hand-wavy nonsense.
Yes 100,000 little projects vs 1...
And I'm not even Anti-solar... after all it's literally just second-hand nuclear production... But it's just that. Second-hand, and why settle for "Second" when we can harness first hand? I'm just not dumb enough to assume it's the answer to all our problems.
No. No I didn't. I was using the lowest life expectancy for nuclear because it steelmanned nuclear for my other critiques. You want to use longer ages, that means you're prepaying 60% of that longer age at cost. I find it interesting that you called me out on trying to give nuclear more benefit. That said, IAEA holds with 30-40 year life expectancy on a nuclear plant so I think the steel-man I chose is acceptable.
Lithium Ion batteries are being used at large scale now, sure. It's dishonest to say the ones being built today for utility-scale power are 1980's technology, just as it's dishonest to pretend that nuclear power is what it was in the 1950's. But there are also advancements in molten sand batteries, and even utility scale water energy storage is going down in price (though I believe it's still slightly more expensive than nuclear).
So how is $140/MWH total cost of energy over the life of a nuclear plant "the long haul" over $77/MWH total cost of energy over the life of a nuclear farm? Do we need to discuss how that kind of math works? Building solar+battery plants, running them till EOL, rebuilding them from scratch and repeating several times is still **half ** as expensive as producing the same amount of energy with a nuclear plant until it reaches EOL.
And considering that cost is effectively more like $1,000/MWH or more for the first few years, how exactly are we going to get carbon neutral any time soon by literally adding an order of magnitude to our costs?
Sure. Being able to plop it down at a massively high price does have its uses. Note I said there CAN be appropriate uses for nuclear. Just not many of them. The price is just unreasonable. And very often, space isn't really an issue. Those 100,000 little projects are still cheaper than that 1 project nuclear for the amount of energy created.
For several reasons. First, the sun is in a state of nuclear fusion which is at least 4x more efficient than can be achieved with fission. Second, the sun is gonna burn whether we harvest that energy or not. Third, the most expensive part of a any nuclear power prospect is causing and containing it. We get to skip that step with solar.
I guess I am "dumb enough". Between the power created from the sunlight itself, and wind and hydroelectric power created indirectly by it. The numbers all work out.
How much of that $140 is labour?
Seems an odd question. Since I'm not sure what you're getting at, my answer might or might not be of value.
The only thing I know offhand about the breakdown is 60% of the total lifetime cost of electricity is in construction costs, a number that is disgustingly through the roof and why using nuclear power for the whole world is unfeasible. It's that bad.
The rest is "day to day costs" which are far lower with nuclear than other forms of energy. Which would be great if it didn't cost so much to build a nuclear plant.
Countries with a lower PPP would get the lifetime cost closer to parity, if a handful of project experts etc are brought in at Western rates and local labour is used for the build and operation. If the federal system of government for that country streamlines the registration process while mandating key critical compliance steps (for instance, full test and verification on the containment system but not the light switch in the control room toilets, which I have read is an issue with the US regs) it would seem that non-us countries would be able to do nuclear cheaper per MWh.
Cheaper than $140, or cheaper than Solar? Someone just got back to me with claims of lower Nuclear numbers... and even in those claims, Nuclear simply could not get anywhere close to Solar.
Probably a third of that cost is tied up in NRA certification with 32 different federal and state licensing bodies, planning, EIS statements which average 6 years to write, and the political approval process.
While you're waiting those six to 10 years to get your project started, you're going to see a construction cost inflation rate of what, 25 to 30%?
Care to substantiate that the red tape amounts to more than 100 years worth of the same MWH of solar? Or is that just your gut feeling?
Also note, even if the construction cost were 30% inflated, nuclear is still losing handily to solar by the figures I cited.
I was half joking, although cost escalation would actually account for a major portion of the cost increase.
We did a new building project. Started during 2021, and by the time we received the final bids costs had increased 50%. All within 6 months. We're at 10% cost escalation this year alone.
Imagine 6 years of that.
However, it also sounded like these companies had no clue what they were doing. Similar to California High Speed Rail.
Of course. That happens. Luckily, we have countries like China with less red tape to use to measure. They've been building a lot of nuclear and solar. Their end-to-end solar looks like around $750M per GW (possibly including storage? Not sure. About $2.2B for a 3.3GW plant). Looks like they're spending about $5B per GW of nuclear.
Sorry I don't have the solar reference anymore. I was building a math equation for another comment and realized they weren't talking price, so scrapped it without thinking.
Since those numbers seem to match US figures, I think people in the Western World forget that a lot of bid cost increases or "escalations" are due to the fact that companies try to low-bid to win the contract, knowing every little inconvenience will require a cost increase. It evens out more than people want to admit.
Yeah I hate dealing with that. Then they send back every design decision to be reopened, resulting in literally years the meetings to decide which source for which equipment, all the while the Costco up to the point where if we just built a damn thing 5 years ago then it would have been cheaper than trying to go with a low bid now. Not to mention years of delays.
Agreed. It doesn't end up saving a penny, but it definitely leads to greased wheels along the way and richer politicians.
This attitude is about a decade out of date. It made sense around 2010 when wind and solar weren't widely deployed and cost more than nuclear per megawatt hour. Now we have more wind and solar deployed than nuclear, and they're significantly cheaper and faster to construct and make better economic sense than nuclear.
There are plenty of safer, quicker technologies available. Repairing the US grid would give us 20% more power.
There are no available technologies safer than nuclear, unless you're talking about the construction. You're literally more likely to fall and hit your head on a solar panel. Which can be serious electrical hazards for firefighters if you're ever unlucky enough to get caught in a house fire.
Well it's a good thing this is only an issue in the states then...
Is the USA doing anything to block other countries from going nuclear?
Not what I'm implying
I fail to understand how managing wastes remotely toxic to all forms of life for 500K years would be economicaly viable. This just calls for increasingly more power demand. It is hard to sell when there are alternatives that are cheaper, cleaner, more scalable, easier to build (eg offshore wind).
Well you see we store this nuclear waste in what we call breeder reactors and continue generating power
Last time I checked, they were actually spending energy to cool wastes during several years.
By realising that what we now call waste will be the fuel source of the future. And also understanding that the renewables require a lot more area, material and energy to build than nuclear: https://robertbryce.substack.com/p/the-iron-law-of-power-density-part
Look up the Finland deep geologic repository, it's meant to be as passive as possible. Also nuclear waste isn't nearly as dangerous as most people imagine it to be.
It's only economically viable if we use the same thinking that got us here in the first place. Fuck the future.
