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.

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.”

Nuclear plant construction delayed? Budget overrun? Even in one of the most nuclear developed countries in the world? Wooooow, what a surprise!!

Renewables are far cheaper and can be built faster and if they malfunction, no one is in danger.

France already has enough Nuclear to deal with no-sun and no-wind phases (if they work properly, which is the other problem with nuclear energy in France)...

So, there is literally no reason to waste tax payer money and time like this and to force yourself to import material from Russia. Just build renewables until we get fusion energy...

Renewables cant produce an on-demand baseload supply without the addition of significant storage capacity.

[–] [email protected] 8 points 2 weeks ago

Baseload is by definition not on-demand, baseload is always there.

its most powerful at 1,600 MW,

Fuck, that's 100 more MW than VVER-1500(project). Or 400 more than VVER-1200(working).

post-Chernobyl

???

is 12 years behind schedule

VVER-1500 is still project for 40 years. Most modern we have now is VVER-TOI (1300 MW).

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.

[–] [email protected] 6 points 2 weeks ago (1 children)

Is that including all known deposits? Or just the amount in current mines?

[–] [email protected] 11 points 2 weeks ago (1 children)

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.

What you're probably thinking about "peak oil." https://en.m.wikipedia.org/wiki/Peak_oil

Nah man. I also heard this back when I was a kid in the 90s. It came from our news channels, not teachers in school.
