For additional context, one of the reason for the delay and cost increase was the absurdly complex design due to French and German companies trying to collaborate on a new design as Germany was turning anti-nuclear, which culminated with Germany deciding to stop nuclear energy after the Fukushima Daiichi event.
Another big reason is the knowledge loss due to almost one generation without any reactor built in between.

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.

Now do Georgia's Vogtle reactors 3 and 4, which came in at 34 billion for 2 x 1200mw plants, 21 billion over the original 14 billion estimate, and took over 14 years to build, 8 years behind schedule.
Im glad these powerplants finally got built. They will help, but nuclear is just not reasonable anymore. Its a slow, expensive tech, especially when we are making such leaps and bonds with solar/battery.
Even if wind and solar make huge progress, they will likely never be as efficient regarding raw materials efficiency and land use. Land use is the main contributor to biodiversity loss.
I don't think peremptory opinions about technologies are going to help. We should use what ever technology is the most reasonable and sustainable for each specific location.
Total land used for all power to be supplied by solar would be a hilariously tiny percentage of land, so this just reads like a solar version of "its killing birds" to me.
Agrivoltaics also side steps this non issue, as interlacing solar panels into farm land increases yields for many crops while making efficent use of space that's already spoiled any biodiversity. Can you do that with a nuclear reactor?

Olkiluoto unit 3 took 18 years: https://en.wikipedia.org/wiki/Olkiluoto_Nuclear_Power_Plant?wprov=sfti1
It’s the same French EPR tech and the whole project was plagued with mistakes because the French wanted to cut corners and just get it built as fast as possible.
Sounds like pretty much every software project I've ever worked on
The difference here was that STUK (the Finnish Radiation and Nuclear safety org) isn’t a backwater shop like the French kinda assumed. It’s a world-class setup that consults around the world.
They caught so many mistakes that the project went ridiculously over time and budget. The French crew had kids born and go to school in Finland before it was over - it was supposed to be a few years of expat experience 😆

They better retool their power plants to use something other than uranium. Last I read, we had about a century's worth at the current rate of mining.
Is that including all known deposits? Or just the amount in current mines?
It's based on what can actually be used.
The world's present measured resources of uranium (6.1 Mt) in the cost category less than three times present spot prices and used only in conventional reactors, are enough to last for about 90 years.

(Note this is a *pro-*nuclear power organization.)
New technology may change that. We were once told that the oil in the Canadian tar sands was not economical enough to extract and now they're extracting it. The paper also discusses the possibility of thorium as a fuel source, although it has yet to see commercial viability.
As-is, and with current reactors, we don't have much we can use. Relying on new technology to change that could be a poor gamble.
When I was at school in the early 90s I was told oil would run out in 30 years, yet here we are, 30 years later and not only did it not run out, but people aren't even talking about it running out.
100 years is a long time, and I suspect that nuclear will seem very old fashioned by then, and today's power stations will have been long since decommissioned. If we're not getting close to 100% of our power from wind and solar and tidal by then, we'll be shafted anyway.

No you weren't. If you were, then you had a terrible teacher.

Don't worry, the consultants are already on the task and invoicing hundreds of millions for their hard work.
No ETA but will keep you posted... in about 12 years.
