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.

Why would they be more financially viable now?
Because cost of megawatt-hour via nuclear power plant decreases every year. EVERY YEAR.
https://www.nei.org/CorporateSite/media/filefolder/resources/reports-and-briefs/Nuclear-Costs-in-Context-2021.pdf
The reason the USA shut down old nuclear power plants decades ago was because they were very expensive. Some of those old reactors were recently acquired by Microsoft in the expectation that rising power demand (and therefor price) would make them viable again.
I'm sure the EU is expecting similar shifts in financial viability as the Russian aggression drags on, eliminating natural gas imports availability.
Nothing in that table is dropping every year.
Capital cost spiked a decade ago, and are now still higher than 2002 levels. Fuel spiked at a similar time and is now back to 2004 levels (but not as low as 2007). Similar story for operating costs.
Basically it looks like 2008 sent nuclear cost through the roof, and it's only just recovering to start of the century prices.
At the top it states these are the costs in USD per MWh after adjusting for inflation.
As you can see, the Operating Costs did in fact spike between 2004 and 2012, but then continued to decrease every year from 2015 to 2020. The Total Generating Costs saw the same spike sometime after 2007 but again went back on the trend of decreasing after 2015.
You've made an excellent point of arguing semantics. I concede that "every year" isn't as accurate as saying "most years except for the spike in 2004-2012".
Falling back to the level they were before the 2008 financial crisis isn't indicative of the technology advancing and a general downward trend. It's just the market normalising.
If we had been not investing in nuclear plants only whilst costs were sky high I'd think you'd have an argument, but we've been avoiding nuclear investments for a lot longer than that.
There have been a lot of technological advances, though. Maybe you just never noticed, but we've had advances in fuel assembly and coolants that allow operation at lower temperature ranges and smaller reactors.
In the future, potential new Thorium Reactors, almost all of which currently operational are for research purposes, could provide another huge leap forward as they produce less plutonium than other standard Uranium isotopes.
Plus, our technology for containing and handling plasma has grown in leaps and bounds, although most of that technology seems to be closely guarded in China so I don't have high hopes for it.
yeah maybe because only the most cost effective ones remain? (natural selection)
Are you saying newer facilities aren't more efficient but instead a random chance which coincidentally leads to anual efficiency gains?
If that were true, we wouldn't need to guess. We could just look at the data showing that new plants provide cheaper electricity.
Thats why I linked the data.
It just presents data without going into detail. You're making unsupported assumptions.
Feel free to present counter-data, then.
....and because the older plants are simply written off already. If you already recouped the building costs, you can charge based on just the running cost.
