France's most powerful nuclear reactor connected to grid after 17-year build (www.lemonde.fr)

Summary

France’s Flamanville 3 nuclear reactor, its most powerful at 1,600 MW, was connected to the grid on December 21 after 17 years of construction plagued by delays and budget overruns.

The European Pressurized Reactor (EPR), designed to boost nuclear energy post-Chernobyl, is 12 years behind schedule and cost €13.2 billion, quadruple initial estimates.

President Macron hailed the launch as a key step for low-carbon energy and energy security.

Nuclear power, which supplies 60% of France’s electricity, is central to Macron’s plan for a “nuclear renaissance.”

This is a poor argument. You just did what you explicitly should not do with Life Cycle Assessment (LCA) results.

The ISO 14044 specifically requires life cycle assessment to include all relevant impact categories. In particular in comparative analysis it is crucial to not single out any one category, but look at the impact on the endpoints, e.g. ecosystems or human health.

See page 37 onwards.

Here is the full LCA study, that you drew only one category from

https://unece.org/sites/default/files/2022-04/LCA_3_FINAL%20March%202022.pdf

Look at the Endpoint indicators, like "Lifecycle impact on ecosystems, per MWh, in pointes", "Life cycle impacts on ecosystems, no climate change,per MWh, in pointes", "Life cycle impacts on human health,per MWh, in pointes" etc.

Nuclear power does fare well in these categories, but often only marginally different to Wind Power and Solar Power. It certainly does not offset the cost difference, when you also have to include the opportunity costs of running coal or gas plants longer.

This is a poor argument. You just did what you explicitly should not do when engaging in a discussion: building a straw man argument and cherry picking a part of an answer.

I highlighted two rarely mentioned and non-intuitive points about nuclear vs renewables, I bet a few readers learned about it. But, I didn't say renewables shouldn't be used. My conclusion says the opposite, don't have blocked opinions about technologies, use whatever is most adapted to the location, if it's renewable, that's great.

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.
