We learn something new every day. This is a community dedicated to informing each other and helping to spread knowledge.
The rules for posting and commenting, besides the rules defined here for lemmy.world, are as follows:
Rules (interactive)
Rule 1- All posts must begin with TIL. Linking to a source of info is optional, but highly recommended as it helps to spark discussion.
** Posts must be about an actual fact that you have learned, but it doesn't matter if you learned it today. See Rule 6 for all exceptions.**
Rule 2- Your post subject cannot be illegal or NSFW material.
Your post subject cannot be illegal or NSFW material. You will be warned first, banned second.
Rule 3- Do not seek mental, medical and professional help here.
Do not seek mental, medical and professional help here. Breaking this rule will not get you or your post removed, but it will put you at risk, and possibly in danger.
Rule 4- No self promotion or upvote-farming of any kind.
That's it.
Rule 5- No baiting or sealioning or promoting an agenda.
Posts and comments which, instead of being of an innocuous nature, are specifically intended (based on reports and in the opinion of our crack moderation team) to bait users into ideological wars on charged political topics will be removed and the authors warned - or banned - depending on severity.
Rule 6- Regarding non-TIL posts.
Provided it is about the community itself, you may post non-TIL posts using the [META] tag on your post title.
Rule 7- You can't harass or disturb other members.
If you vocally harass or discriminate against any individual member, you will be removed.
Likewise, if you are a member, sympathiser or a resemblant of a movement that is known to largely hate, mock, discriminate against, and/or want to take lives of a group of people, and you were provably vocal about your hate, then you will be banned on sight.
For further explanation, clarification and feedback about this rule, you may follow this link.
Rule 8- All comments should try to stay relevant to their parent content.
Rule 9- Reposts from other platforms are not allowed.
Let everyone have their own content.
Rule 10- Majority of bots aren't allowed to participate here.
Unless included in our Whitelist for Bots, your bot will not be allowed to participate in this community. To have your bot whitelisted, please contact the moderators for a short review.

And the amount of uranium available would only get us through to the end of the century.
Some countries successfully dismantle the remnants of the rods. Residues are extracted from spent nuclear fuel and rods are made not on uranium but on plutonium. The remmans of this rods is even more enriched than before reaktor starting work. as a result, it is possible to burn unenriched uranium and other heavy nuclei, so that the fuel will definitely last for a long time.
"[Nuclear] is costly, potentially dangerous, that there are problems dealing with and siting waste, and that future generations are left with a legacy they will not appreciate. ...uranium is itself a non-renewable resource, due to run out well before the end of this century. So even if it were to be cost-effective, safe, and harmless to future generations, nuclear energy is not a long-term solution to humanity’s energy problems."
Dobson, Andrew, (2000) GREEN POLITICAL THOUGHT, United Kingdom: Taylor and Francis (Books) Limited, pp.56
Standard green party retoric, they don't see the forest for the trees.
If we had built nuclear power plants and closed coal, oil and gas power plants back in 2000 we would have several nations with a carbon free grid these days.
I don't think Dobson is out to mislead people from an academic point-of-view, so I take the uranium comment as being true. If it is the case, then I'm not sure how you had better insight into the future of nuclear power.
Read their arguments above. Also, is it this Andrew Dobson? An academic but hardly an expert on the nuclear physics.
He is quoting another source (I haven't got the rest of the book to hand).
Oh, if only the reactors worked exclusively on uranium. Of course, I can quote Rosatom's articles, but unfortunately they are only in Russian. A closed fuel cycle was developed there back in 2015. If you want you can use Google translate: https://habr.com/ru/articles/388533/
P.S. It is very specific to get scientific knowledge from a book called GREEN POLITICAL THOUGHT
Thanks, I'll check it out, Google Translate usually works well on links.
Edit: tried reading it, got about half of it. How long is this closed-loop supposed to last until it is all spent? I didn't see mentions of that, just about uranium no longer being an issue.
I quoted that as I'm currently reading through it as part of my master's and it seemed particularly relevant. Dobson looks at different aspects from different perspectives, not taking particular sides. The quote above is from the 'greens' perspective; Dobson mentions the possibility of future technological advances.
At the beginning of the article, it is mentioned that only the use of uranium-238, which is now not used, will expand the reserves of nuclear fuel by about 200 times.
UPD: also in another article I read that not all uranium is completely destroyed in the reactor cycle, the rest turns into radioactive waste, which in a few years can be cooled and recycled into new rods for the reactor. in France, for example, they have been doing this for a long time.
