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.

No it wouldn't. China laid more concrete in 5 years than the entire world did in 100 years. I highly doubt that converting the entire world to nuclear is going to use that much more concrete. I mean hell, they laid like 15 or 20,000 miles of high speed rail in just a few years. They built like 300 million apartment units.
Just did a bunch of my own math before realizing those numbers were already out there. We would need to add 3960 nuclear plants to match current energy demand for the world (440 power 10% of the world).
That would require at least 5 years of construction per plant. It takes about 7000 workers to produce a nuclear plant. To produce them concurrently would require about 27.7 million construction workers dedicated to this project for at least 5 years. So on one hand, perhaps you're right, since there are 100M construction workers in the world. I can't, however, find numbers about how much heavy equipment exists to facilitate a product requiring 1/4 the world's construction workers concurrently. You might be right that if all other construction were ground to a halt, we might be able to manage a 5-year plan of nuclear at the cost of about $20T (I had done the math before realizing this reply were about workers, not cost stupidity). I concede it seems "10x increase world construction capacity" was wrong, and the real number is somewhere around 1.5-2x, so long as we stay conservative with nuclear figures and ignore extra costs of building or transporting nuclear energy to countries incapable of building their own plants.
Interestingly, at those construction numbers, you could provide small-project rooftop solar to the world. I can't find construction numbers for power farm solar, except that it's dramatically more efficient than rooftop solar. Unlike nuclear, it appears we could easily squeeze full-world solar with our current world construction capacity.
I won't bore you with the cost math, but since I calculated them I'm still going to summarize them. Going full nuclear would cost us about a $20T down payment. Going full solar (with storage) down payment is about $4T (only about $1T without storage costs factored). And while nuclear would be cheaper than solar per year after that $20T down, solar power and storage would STILL be cheaper in a 100 year outlook, but would also benefit from rolling efficiency increases as we add new solar plants/capacitors and tear down older ones..
Not all 7,000 construction workers would be working on the site concurrently. Different trades come and go depending on the phase of the project. So at first you'll have the civil engineering earth movers come in, who clears the site and excavates the foundations. Then you'll have the concrete crews come in who pour the foundations and do all of the concrete work. Obviously on a nuclear power plant there is a lot of foundation work, as well as a lot of above ground concrete so probably a good chunk of the construction workers will fall into this category.
Power plants also have a lot of structural steel work, electrical and special equipment that would likey fall under the piping category but each of these uses a separate set of skilled labor that does not overlap.
If you were going to actually try to build 3,300 nuclear power plants, you would rotate crews from project to project which would increase efficiency rather than hiring 27 million separate workers.
In any case, I don't think converting the world's total electrical power generation to 100% nuclear is by any stretch of the imagination a good idea. Personally I think maybe 15 to 25% nuclear power generation would be a more realistic mix, similar to the US electrical power generation. The rest of the power should be solar, wind, hydro, wave and geothermal as they are absolutely cheaper to build.
I'm not sure I agree with how you'd be able to execute on that level or organized construction safely, but I think we're also reaching the "impossible-to-be-sure hypothetical" territory, so I'll concede the point for now.
I think my problems of cost and time still stand. It looks like adding rooftop solar with batteries to every building is still cheaper (on startup, and likely per MW) than nuclear plants. Regions that cannot support solar, onland wind, geo, or hydro can justify nuclear (at least unless shipping batteries or hydrogen conversion becomes cheap enough to compete), but I don't think they amount to nearly 15% of the power needs in the world since they represent fairly distinctive regions with low energy demand.
We do it all the time in the construction industry.
For instance, Bechtel has 55,000 people in the US.
So just hire them. Too bad they lost almost all of their institutional knowledge about nuclear construction compared to what they used to have.
