All this debate and nobody brings up that, thanks to climate change, cooling nuclear power plants will become a roll of the dice? Same as it already happened in France?

Droughts are really, really bad for nuclear power. Solar and wind don't give a shit.

Doesn't even matter much which technology is better on any other point. If you cannot run it, it's worthless. Especially at times with increased power demand for example due to AC usage spiking thanks to the same heat that just poofed your cooling solution into oblivion.

Thank you. The nuclear fanboyism is crazy here and on reddit. Looking back, almost all nuclear power planta in Germany had to shut down over the last summers, because the cooling water Was either not enough or too hot. That technology has run it's course and every potential investment is better routed towards renewable, battery capacity or green hydrogen.

In addition, the european pricing for power is defined by the most expensive source - and nuclear as well as coal are power sources that are getting more expensive, raising the cost for users. Supporting both sources for energy is madness.

And yes, tearing down windfarms for coal is fucking stupid, as is hoping that russia will keep selling us gas. Europe needs it's own power infrastructure and has enough potential for it.

I've seen another video article instead that basically says sure nuclear is good on paper if:

  • power plans should be 4th gen... which are non-existent at the moment (if not at the prototype stage only) and which construction in case will take decades and which costs are huge and also hard to estimates, even for France who has built a lot of nuclear power plans along the years and has probably the better know-how resources on the matter
  • not everyone should go nuclear at the same time, because if everyone does:
    • fuel material market price will increasingly raise due to its demand making nuclear energy production inherently less convenient as time passes and the fuel stock gets depleted, in turns shrinking the offer
    • all known stock of fuel material at the current usage are estimated to run dry in 120 yrs (so immagine if you wanted to convert today a country to full nuclear power it will probably require 50 yrs and last only 70 at best), but the remaining stock will surely last a lot less if suddenly everyone should convert to nuclear energy production

The article and the video are in Italian, so I'm afraid at best you can only translate the written article to your language of choice

Great post and nice to see those 4th gen plants mentioned including the current project development state. Those plants were always a top comment as 'the solution' in discussions on Reddit. Just build 4th gen or molten salt or fusion - energy problems solved with just a few keystrokes.

Posts explaining the problems or the current state of those projects often ended up in flames.

[–] [email protected] 20 points 1 year ago* (last edited 1 year ago)

Not to mention that building new plants can take a decade and costs a fortune - if you invest that money into renewables and power storages you have working power much faster.

Also OPs graphic is a real problem but it only goes until last year where we just got rid of Merkel. Her party was actively working on making it as hard as possible to work wind turbines while investing into gas from russia so with the new government the speed should finally pick up again

Of course shutting down existing nuclear reactors is a bad idea (which also happened because of Merkel) but that decision was made so long ago that the companies running those plants prepared for them to shut down for a decade and have stopped hiring people, the ones working there are on retirement contracts and they didn't invest into future proofing the plants anymore so they were kind of falling apart

Don’t import Reddit’s extremely ignorant takes on nuclear power here, please. Nuclear power is a huge waste of money.

If you’re about to angrily downvote me (or you already did), or write an angry reply, please read the rest of my comment before you do. This is not my individual opinion, this is the scientific consensus on the issue.

When it comes to generating electricity, nuclear is hugely more expensive than renewables. Every 1000Wh of nuclear power could be 2000-3000 Wh solar or wind.

If you’re about to lecture about “it’s not possible to have all power from renewable sources”, save your keystrokes - the majority of studies show that a global transition to 100% renewable energy across all sectors – power, heat, transport and industry – is feasible and economically viable. Again, this isn’t my opinion, you can look it up and find a dozen sources to back up what I am writing here.

This is all with current, modern day technology, not with some far-off dream of thorium fusion breeding or whatever other potential future tech someone will probably comment about without reading this paragraph.

Again, compared to nuclear, renewables are:

  • Cheaper
  • Lower emissions
  • Faster to provision
  • Less environmentally damaging
  • Not reliant on continuous consumption of fuel
  • Decentralised
  • Much, much safer
  • Much easier to maintain
  • More reliable
  • Much more responsive to changes in energy demands

Nuclear power has promise as a future technology. It is 100% worth researching for future breakthroughs. But at present it is a massive waste of money, resources, effort and political capital.

Nuclear energy should be funded only to conduct new research into potential future improvements and to construct experimental power stations. Any money that would be spent on nuclear power should be spent on renewables instead.

Wow I'm surprised to see people are actually downvoting you and arguing about this. It's common knowledge that the cost, impact, and build-time of new nuclear plants makes them a poor choice for energy. Not only is wind/ solar cheaper, it's faster to build.

[–] [email protected] 19 points 1 year ago

Redditors are unbelievably brainwashed in this topic, and a lot of Redditors moved over to Lemmy. I have dragged this metaphor to water countless times before, and when I suggest that they could consider drinking, they just arrogantly declare that I don't understand the facts around liquids, that I don't have any basis for my claims that they should drink it, and that by arguing that people should drink more water, I somehow supporting Coca-Cola.

You can have this copy/paste from like 5 minutes of googling. You can also run your own study yourself by just googling "average kwh price nuclear" and "average kwh price wind" and see how it looks. You can also google "average co2 eq emissions total lifetime nuclear" and likewise for wind/solar PV. This is extremely simple stuff, guys. I am basically saying, "lentils are cheaper than steak" and you're asking for citations.

Wow look isn't it crazy how nuclear is the most expensive one?

Mycle Schneider, author of the World Nuclear Industry Status Report: "Nuclear power plants are about four times as expensive as wind or solar, and take five times as long to build. When you factor it all in, you're looking at 15-to-20 years of lead time for a new nuclear plant."

Differences in carbon emissions reduction between countries pursuing renewable electricity versus nuclear power, published in nature energy: "We find that larger-scale national nuclear attachments do not tend to associate with significantly lower carbon emissions while renewables do. "

I hate when people say “stop importing it from Reddit” like half of us didn’t migrate from there.

What the fuck did you expect to happen? Reddit didn’t believe that. The users that participated in the site did.

Although I agree with this comment, this is exactly what the covidiots said. "Just google it". If you want us to believe your controversial opinion, you're going to want to take the time to add the most credible sources you can find to back you up.

not with some far-off dream of thorium fusion breeding

Thorium reactors were made those in the 60s, they weren't pursued because thorium can't make nuclear bombs.

I agree with you on nuclear being more expensive as all facts point that way and future nuclear technology, but i dont understand how we could transition to a 100% renewable energy sector, It would be good if you could give a citation or explanation for that. Diverse and distributed source is how we get an energy secure grid, renewables could help with the distributed source part, but when it comes to diversity the popular renewable technologies wind and solar are very limited, both of these source cant power a base load without batteries (this applies mostly to solar, but wind too has low output at night). Also there is this issue witj managing generation and demand (Nuclear too have issue with this as its not possible to quickly adjust nuclear power generation like other conventional spurce). A full renewable energy grid would depend on batteries, currently we have much limitation with batteries. Mature technologists of acid based batteries require huge areas, and lithium based ones would require rare lithium which its mining alone would cause alot of pollution, and relying on other alt battery technology itself would be a long stretch as its development and commercialisation to usable form would take years to achieve as the same case afforable future nuclear technology.

Other alt renewable energy like geothermal could help with base load (not sure, someone could correct me if this is not the case), but itsnt possible everywhere. The same goes for tidal plant as it depends on geography and specific time of day. With this scenarios if we were to move to a 100% renewable grid then, the price for energy will increase at night time in a way that i think could reach nuclear energy rate.

A 100% renewable grid would need a lot of batteries and that too could drive the price up and possibly contribute to climate change. Also solar panel manufacturing is a very intense process with a lot of carbon impact, i read this on a text during my academics (havent checked the source for this other than that).

Yes, what you are missing is reality.

You can either build renewables to replace fossil fuels in the next years (and if the build-up doesn't work as fast as you want to then it will takes a a few years more to reach zero), getting less and less every day. Or you can build new nuclear reactors and just keep burning coal full steam for 5 years, 10, 15, probably 20. And then you reactors are finally online, but electricity demand has increased by +100% (and further increasing...) so you burn more coal for another 5, 10, 15, or 20 years...

The exact same thing happens btw right now in basically every single European country that promotes nuclear. Because nobody is building enough capacities to actually cover the minimal required base load in 2-3 decades (electricity demand until 2050 will raise by a factor of 2,5 at least - because most countries today only cover 20-25% of their primary energy demand with electricity but will need to raise that to close to 100% to decarbonize other sectors; so we are talking about about a factor of 4-5, minus savings because electricity can be more efficient). They just build some and pretend to do something construtive, while in reality this is for show and they have basically given up on finding a solution that isn't let's hope the bigger countries in Europe save us.

For reference: France -so the country with optimal conditions given their laws and regulations favoring nuclear power and having a domestic production of nuclear reactors- announced 6 new reactors with an option for up to 8 additional ones and that they would also build up some renewables as a short-term solution to bridge the time until those reactors are ready. That's a lie. They need the full set of 14 just for covering their base load for their projected electricity demand in 2050 and that's just ~35% of ther production with the remaining 65% being massive amounts of renewables (see RTE -France' grid provider- study in 2021). Is this doable? Sure. It will be hard work and cost a lot of money but might be viable... But already today the country with good pre-conditions and in-house production of nuclear reactors and with a population highly supportive of nuclear can't tell it's own people the truth about the actually needed investments into nuclear (and renewables!), because it's just that expensive. (Another fun fact: The only reason why their models of nuclear power vs. full renewables are economically viable is because they also planned to integrate huge amounts of hydrogen production for industry, time-independent export (all other countries will have lower production and higher demand at the same time by then) and as storage. So the exact same thing the usual nuclear cult here categorically declares as unviable when it's about renewables.)

is it true that in reality we can only build renewables OR nuclear? i feel like that's not reality.

I'm reality, the world is burning and both techs will mitigate. instead of resisting nuclear, renewable advocates ought to go after fossil fuel subsidies

Nothing you said other than expenses is an argument against nuclear. If anything, the take from you argument is that we should construct even more nuclear, not less.

[–] snake 14 points 1 year ago

Yes, nuclear taking too long to build is not argument, it just means we should have started building them already.

Ontario Canada constructed 20 reactor units between 1965 and 1994. While the CANDU units are no doubt different from the designs used by France, 14 in 26 years is certainly achievable. This does not mean renewables should be disregarded, but both options should be pursued.

Tbf it's starting to be too late, even if they were pro nuclear it's going to take like 20 years

[–] [email protected] 16 points 1 year ago (1 children)

Better start now than wait then.

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

Yes pouring down money on a technology, that at best can help us mitigate emissions in 20 years, instead of investing it in a scaleable and cheaper technology now (wind, solar) is a great and reasonable strategy...

And that is entirely ignoring the debate abou the safety and waste issue of nuclear power.

Scholz is right that nuclear is dead in German. Nuclear is always political and there's no stable political majority pro nuclear. This has nothing to do with the technology. It just won't happen.

Most entreprises, energy or else, are privately run and financed. Capitalism. Nuclear is private on paper, but no one is going to build reactors without governent support. Many industries are regulated, like banking, but they are still driven by profit motives, private interest. At least in Germany, there's no entrepreneurial mindset behind nuclear. Rent seeking business people and lobbyists, sure. But not risk takers. The businesses lobbying pro nuclear are lead by ex-politicians and similar types who secretly want a safe government job.

Nuclear is dead and it's not the biggest problem. The much bigger elephant in the room is that we mostly talk about renewables. Sure, renewals grow, but nowhere near the rate needed. Everyone can see this, the data is available, and we just don't give a shit.

And don't get me started on hydrogen. Doesn't make sense to even consider hydrogen unless you have a huge surplus on (preferably renewable) energy.

Are you intentionally omitting the amount of wind being added by other countirss around Germany? There is massive increase of renewables being added to the North Sea, for example
