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 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.

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.
