The discourse on nuclear is still quite chaotic in politics in Switzerland. All left leaning parties and greens parties are strongly against nuclear. I am not expecting informed and civil discussions about this topic.
Switzerland has a summer/winter energy problem. We have lots of potential of producing energy in the spring and summer (when our dams are full from the melting of snow and the sun is shining), and much less so in the winter. We can still improve 10 to 20% our hydro production, but that's it. All the water sheds are already well used and rely on our glaciers to replenish, which will become less predictable with climate change.
We shouldn't completely closing the doors to all forms of nuclear technology. Obviously, we can't build blindy without any considerations. But we may need it on the second half of the century, especially if we are going to electrify all forms of transport. We can't be buying France's nuclear energy all the time.
I’m against a lot of Hydro power in the US because the environmental damage is high. Plus I like to fish and they have huge impacts on the ecosystems. But these are relatively flat places compared to Switzerland.
Finland has given the initial permit for three nuclear reactors in the past 25 years. One was eventually built after massive delays and cost overruns. Another was canceled, because the company chosen to build it first proved to be incompetent and later also politically undesirable. As for the third reactor, the company that got the permit determined that it makes more sense to invest the money in something else.
At this point nuclear is just a dead horse. It hasn't managed to displace fossil fuels in over 70 years - a feat that renewables have done within 20 years. Nuclear is too slow and too expensive.
https://www.reuters.com/sustainability/climate-energy/france...
Your statement about "We can't be buying France's nuclear energy all the time" really stood out to me.
Are Swiss folks maybe acting a bit NIMBY by not allowing nuclear in their own country, but are fine with buying French nuclear power? It seems a tad hypocritical to be against nuclear, while simultaneously using it as long as it's "not in my country".
This is like firefighters opposing using water.
We had a nuclear meltdown in an experimental reactor in Lucens (https://en.wikipedia.org/wiki/Lucens_reactor).
Does discourse from neighboring countries leak in as well? For example, German and Italian media's anti-nuclear sentiment versus French media's neutral to vaguely positive sentiment about nuclear.
But, Germany's decision after Fukushima to close down all nuclear reactors has had a strong impact on the 2017 votation that banned nuclear in Switzerland. So I guess the influence is there.
SMR make as much sense as space datacenters. You can gaslight investors, you can gaslight HN, you can gaslight a national parliament full of lobbyists, but you can't gaslight thermodynamics.
We should focus on extending our hydro power storage capacity instead.
There will be a referendum anyways, so I think it's unlikely the ban will actually be lifted.
Which nuclear inevitably does, both in the form of direct requests for money and by refusing to pay for adequate insurance to compensate everyone who will be damaged in the event of a meltdown externalizing the risks.
That's a helluva prediction.
Thorium reactors would be practically limitless in fuel supply, but we aren't getting them without seriously funded nuclear research. That is far less likely during a band on commercial stations.
The same reactors nuclear powers with decades of experience haven't deployed?
We will get two or three revolutions in solar power and battery technology before a single thorium reactor is viable. You could invest all the R&D budget of thorium reactors in perovskite panels and it would generate more MW per CHF invested.
We still have to deal with the consequences of a referendum hold not so long after che Chernobyl accident which made it illegal to build and operate nuclear power plants.
They are in the process. Last I checked the bill to do so had passed the lower house and how needs to get ratified by the senate.
https://www.world-nuclear-news.org/articles/italian-bill-on-...
Edit: and with the Mediterranean and rivers warming severely - and the latter even suffering from draught - how are you going to cool down your reactors? Nuclear in Italy is a non-starter.
We still need rotating mass to keep the grid stable, which means either building giant flywheels, keep burning gas or bring nuclear into the mix.
One of these can also produce a ton of energy when needed, the other two cant.
We can and should build more renewables, but we can't risk grid stability!
Do you have any trustable source for this?
It's not a cheap source of electricity, it's a way for someone to get money from taxpayers to subsidize their business.
Probably not economically viable in Switzerland though.
Especially nuclear. It is now economically non-viable.
Keep in mind similar things have been said about solar and wind previously.
There are people which want the best we can do (eg, no Ng, coal, etc) in electricity generation. Sensible reductions, that sort of thing. Then there are those that just want no electricity to be used at all, ever, period.
They'll complain about hydroelectric(carbon in cement production), about things which can happen with nuclear(accidents), about birds in windmills, about the production methods of making solar panels, and so on. To such people, doing anything is bad for the environment, so therefore, every type of power generation is bad.
To listen to such people is, of course, madness, as is listening to all extremists. We should simply ignore them completely, but of course the news exists, fake protestors exist which are paid, and so on and so forth.
Great news, just hoping the people understand this as well.
0: I personally like the look of wind turbines but I understand many don't. The appearance is likely why the Trump administration canceled such projects.
https://www.heidi.news/explorations/black-out-le-talon-d-ach...
Switzerland, unlike the USA, seems capable of safely operating these plants, and with advances in breeder technology new plants doesn't nessecarily mean new mining operations, which often are quite harsh on the surrounding area.
I would have said that about the Japanese as well…
https://pris.iaea.org/PRIS/CountryStatistics/CountryDetails....
Switzerland also studied nuclear weapons production until 1988:
https://en.wikipedia.org/wiki/Switzerland_and_weapons_of_mas...
If the Swiss thought it was in the national interest to exit the Nuclear Non-Proliferation Treaty and crash-develop a nuclear deterrent, I think that they could achieve nuclear breakout quickly.
Nuclear is vastly more expensive per MWh than renewables. It's better than pumping stuff out the ground sure, but that's about it.
It can't cope with peaks. It has to generate the same power 24/7 to be anywhere near economical at two-three times the cost of solar+storage, so it either needs massive storage or massive overprovision
Lets say you have a peak demand of say 40GW but average demand of 600GWh a day (25GW), or 219TWh a year
Lets also say you have to shut down a plant for a week a year for maintenence
You need to build five, 10GW plants to meet your demand.
They provide 5 * 10GW * 24 hours * 7 days * 51 weeks or 428TWh.
If nuclear is $110 per MWh, that means it's going to cost you $47b a year to generate your power requirement, or $215 per MWh
So you're needing to roll out storage, same as you do for wind and solar, or spend twice as much on overproducing.
you are in this thread a lot, so i am guessing you must be very familiar with the industry. maybe you can help me understand:
is the wikipedia on SMRs incorrect/lying when they say that there are commercially operating SMRs since 2020?
and how have so many smart people and companies been duped into seriously considering SMR technology if SMRs apparently break the laws of thermodynamics?
So a whole lot of sense given the entire US Navy uses them and I already have one datacenter operating up in space (small test unit that over 3 months has provided ZERO issues) and a bigger one heading up into orbit next year when it's done being made.
"but you can't gaslight thermodynamics"
No but you can certainly conflate them like you're doing right now.
Nuclear has had its moment. That moment is gone.
"Nuclear has had its moment. That moment is gone."
When CO2 caused climate changed is posed to be civilization altering this is a very very foolish thing to say.
At a certain point, dollars are funny money if you are destroying the environment to save a few now by generating baseload with a carbon-producing tech.
Of course, let’s build the safest and most efficient nuclear that we can, but “its capex is too high” is not a compelling argument to me.
And to be clear: renewables should form as much of the capacity as possible, but a reliable baseload is obviously still needed.
Baseload was a cost optimization. Back in the day it was cheaper to build coal & nuclear plants that took days to power on. Somebody figured out that if a grid was built of a mix of those cheaper plants and more expensive plants that could start up quicker, it would lower costs. The typical grid was baseload coal and gas peakers. But ~20 years ago gas peakers became cheaper than baseload coal and any need or desire for baseload generation went away.
China is building a lot of coal plants to complement their solar buildout. Notably these are not base load plants. Their new coal plants do not run 24/7, they only run at night.
Similarly, many new nuclear plant designs are not base load designs; they are designs that can be safely and quickly turned on and off.
P.S. the correct term for generation is "non-dispatchable", not "baseload"
Baseload won't be price competitive with renewables in average or shiny/windy conditions ever
In the meantime in Switzerland:
"Our cheapest electricity product is nuclear electricity."
New nuclear power plants would be much more expensive at $180 / MWh or more, due to strict modern regulations. Even with these regulations, there is no nuclear plant that is safe against a terrorist crashing an airplane into it.
The unsolved permanent repository problem is left to future generations.
Finally, building a new nuclear power plant will easily take a decade or more.
Fact of the matter is it takes a large upfront investment to build a nuclear reactor and it has a longer time horizon before it becomes profitable in comparison to something like a gas or coal power plant.
It comes down to whether or not the country, government, citizens and country have the ability to think beyond a 4 year horizon or not.
France tried it. Now their nuclear operator is €50 billion in the negatives, makes about €3 billion per year in profits and has to invest about €150 billion in new reactors, upgrades, refits and infrastructure.
Nuclear is just not worth the hassle.
Switzerland has no uranium and no strong relationship with an uranium-producing country. They also regularly antagonise the EU (especially the far-right isolationisz SVP/UDC, which is... pro-nuclear, of course) which controls every way fission products could be brought inside Switzerland.
The same far-right country is also the one who wanted to cap the population because "there isn't room anymore", but I guess there is now room for massive nuclear plants and the storage of fuel and spent fuel shrugs
Nuclear will also boil over Swiss rivers and shallow lakes.
Note that it’s similar with eoliens wind turbines, they are heavily subsidized
So this is fixing nothing short term.
...or the externality-free fossil fuel industry?
50% of all energy in the swiss economy is oil / gas. Of the remaining 50% (electricity), 2/3 are generated by hydro. The remaining ~1/3 by nuclear fission.
Swiss electricity prices are sky-high, and the demand for electricity is going to continue to rise.
To remain a competitive industrial economy, to transition away from oil/gas, and to offset any potential losses of hydro power as glaciers melt, nuclear + solar is the only real path for switzerland.
I can understand people objecting to plastering the south facing unshaded Alps with panels, but .. it would certainly generate a lot.
I'm a lftr enthusiast, but everyone needs to keep in mind that fission is just fundamentally economically non-competitive compared to solar and wind.
And all those stories about fusion being right around the corner? Yeah, that won't be economically competitive either.
I personally am not in favor of closing down existing fission nuclear plants. By the construction of new fission plants is an economic boondoggle: big, long time, cost overruns, more expensive.
I had hopes for smrs to fundamentally change the economic game but they aren't. I just don't think that solid fuel rod nuclear can ever be economically competitive.
I think I'm back to my original lifter enthusiasm, where lifter is able to use 90% plus of the core nuclear fuel and breed more of it from ultra cheap thorium, and is safer and can be scaled by design....
I think nuclear industry should spend another 10 to 20 years engineering developing a fundamentally economically competitive nuclear plant that will also give time for the price improvement, curves of solar wind and storage to stabilize.
Because solar wind and storage still have a lot of runway for improvement between sodium ion batteries perovskites and just general improvements to wind rotors and general economies of scale
In fact, if the AMOC weakens/stops then there will be a drastic drop in precipitation across Europe and funnily enough maybe the temperature drop so much that the little snow there will be won't melt in big enough quantities.
Of course this is just a ban lift, meaning that there are no concrete plans to build one or more, but if there is a need to move "fast" (nuclear is not, I know) at least there is one less hurdle. I sincerily hope we invest in other technologies, especially now that Sodium batteries seem on their way to solve grid level storage, but I don't necessarily see this as a bad move per se.
Edit: Not Norway - Doh!
- We have a lot of hydro, that are very cheap to produces and for some of the power plants we fill up water by using solar and wind when that is very cheap and generate power back when it's demand for it (meaning selling it expensive)
-Norway export more then we are importing. But that could shift in the coming years.
-Nuclear power are expensive, so with the current prices it do not make sense to have nuclear in Norway. Thought that could change (see point 2)
- not sure what you mean by "little land usable", you can absolutely be correct. in terms of size we are bigger then Germany. But I'm not sure how much usable land there is vs other countries. We do not have that big population but it's spread out and no one wants a wind park in their neighborhood
https://www.nuklearforum.ch/de/news/neues-kernkraftwerk-im-a...
(I wouldn't assume the Swiss are there yet, but I've only visited a couple times for a few weeks. Their politics seemed healthier than I've seen elsewhere, fwiw.)
https://en.wikipedia.org/wiki/Inverter-based_resource#Grid-f...
This competes with the traditional giant flywheel option ( https://en.wikipedia.org/wiki/Synchronous_condenser ), which has the advantage of being a simple and proven technology, and handling brief overload better, but the disadvantage of having moving parts. It's not clear which option is currently best. Both are in current use.
China probably fits in the "politically undesirable" category these days.
Solar and wind is still vastly cheaper for them and still much cheaper when paired with storage.
Second is that nuclear reactor efficiency tends to improve with size. The ratio of thermal watts to electric watts tends to be better with large reactors. I'm not super well versed on the engineering tradeoffs here by my rough understanding is that waste heat scales with surface area while useful energy extraction scales with volume.
Russia actually does have a smallish SMR but it wasn't terribly cheap to build nor operate. IIRC it is in the form of a ship and used to power a city somewhere in the north.
SMR has a place for sure but no one has demonstrated the unit costs savings of making a lot of them yet.
You can actually get some, if not most, of the economy of scale by doing a fleet build of one specific design. The US seems to be working on that and picked the Westinghouse AP-1000. I think that initiative has a decent chance of succeeding. The first few will be slow and expensive to build (even China has had delays with their nuclear roll out) but the subsequent ones will get cheaper and faster to build. This is how some countries did it during the first nuclear power expansion era.
That’s baseload! Baseload is load you can’t turn off: the minimum load that’s required in a 24 hour period. It can be fulfilled with non-dispatchable sources, but it need not be. In this case, China is building coal plants to address the baseload that doesn’t go away at night when the solar isn’t producing.
Is the business of the US Navy to sell electrity on the market?
You are the one conflating things that have absolutely no connections.
Obviously Norway has massive amounts of offshore wind potential too
And that price will only get cheaper, as both the US and China continue ramping up production.
Nuclear? It would need to reduce its costs by 70% to get where solar is now. And then do it again to be competitive with where solar+storage will be in 10 years.
Nuclear is economically a dead technology.
The reality is that solar and wind anticorrelate more than you think, demand shifting (e.g. charging the car when it's sunny) is easier than you think, batteries and pumped storage and power2gas are cheaper than you think and nuclear power is way, way, way, way more expensive than you think.
despite 70 years of tinkering and trying it hasn't managed to make a noticeable dent in fossil fuel
Except for France which came up with the clever strategy of "not banning it", but that was apparently a mistake and they should have just used fossil fuels?
Now their nuclear operator is €50 billion in the negatives
€50 billion for several decades of clean energy seems like a pretty good deal.
It's probably too expensive, because the best way to make nuclear cheap is to build it 'at scale', and here I mean, continuously. You need a company that will get a reactor out of the ground every year or so, continuously, to avoid loosing knowledge and build upon failures or success.
I know three persons who work or used to work directly with nuke plants, one my age who is currently working in getting the newest french reactors off the ground, and two who are friends of my father, one who finished his career in China, and the other became a submarine welder. From the discussion I've listened to, and especially from the welder, the technical requirements are very high, knowledge and techniques have been lost and making nuke plants correctly nowadays on the first try would be a miracle (he is also very skeptical of the first wave of french reactors), you need to iterate and build knowledge, which isn't cheap.
France is not "struggling", they are once again the #1 electricity exporter in Europe, with low-electricity prices, reliable supply, huge profits, and world-beating CO₂ emissions.
Their newest energy roadmap has drastically reduced renewables build-out, while at the same including first 6 and then 8 new EPR2 reactors.
The reason there is so little wind power: Probably the same reason the western, alpine parts of Austria have basically zero wind power - and why neighbouring Carinthia recently voted in a referendum to ban it completely.
People who live in the Alps generally don't like seeing the mountains altered. It is treated almost as sacrilege. And since these areas are heavily dependent on tourism, where the appeal rests on a romantic, Disney-fied fantasy of wild, untamed nature, locals worry that turbines would make the region less attractive to tourists. Of course, this "untouched" landscape is largely a fiction in the first place: most of it looks the way it does precisely because people have lived in it and shaped it for centuries.

Given how my grandmother said every ailment under the sun was due to the Föhn, putting a windmill up would probably be seen as tempting the fates. /s
I'm joking wrt to wind energy, but the cultural associations with wind are real.
The fact that we haven't seen more widespread use of SMRs suggests that you're right. But it's important to point out that there are cost saving opportunities that could potentially reduce the net price per watt despite worse thermodynamic efficiency.
And the link between thermodynamics and the price of electricity is what?
And struggling, propped up by taylor-made laws and public money.
>how have so many smart people and companies been duped into seriously considering SMR technology if SMRs apparently break the laws of thermodynamics?
Never said they break the laws of thermodynamics. They are just inefficient and will never be more efficient than alternatives such as... Bigger nuclear reactors.
Or solar.
And how long have you been out there? Have you never seen investors dumping and wasting billions in dead-ends? Never seen a mania before?
Nuclear attracts clever people, but it isn't smart nor wise.
Nuclear power plants are eye watering levels of expensive. The require massive scale and cost with lengthy approvals and requirements, the fundamental idea of SMRs is to move that cost and approvals into a smaller scale so that multiple standard units can be produced and deployed in a turnkey situation, they still will be expensive but the time to deploy and cost will be significantly reduced.
We also know SMRs work very well, considering the majority of the US Navy is powered entirely with SMRs and have been for a very long time. Off the top of my head ship power has been exported to local areas for disaster relief
Solar is absolutely fantastic and your average person should not be hawking at solar for your home to offset your power bill. The problem with solar is that you need power 24/7 and solar will not make power in the night.
I don't think the likes of Westinghouse, Siemens, Rolls Royce and GE are duped. They are trying to solve a very hard problem!
Ok, question: for the cost of one nuclear power plant, how many batteries can you have?
For the cost of the R&D of one next generation nuclear reactor design, how many next generation battery and solar panels technologies can you develop?
true, you said "gaslight thermodynamics", which i have no idea what that means, so i took a guess at what you were implying.
>never be more efficient than alternatives such as... Bigger nuclear reactors.
is efficiency really the only metric to be considered? i feel like available space, availability of alternatives, time to complete construction, etc. are worthwhile to consider.
>And how long have you been out there? Have you never seen investors dumping and wasting billions in dead-ends? Never seen a mania before?
considering the length of time and sheer number of people, companies, and governments worldwide considering/investing in SMR tech it seems unlikely to be a mania. but i am not an expert. you are talking like you are one, which is why i am asking questions.
All of these favor again bigger reactors.
>considering the length of time and sheer number of people, companies, and governments considering/investing in SMR tech it seems unlikely to be a mania.
All of the Swiss energy companies are asking to be bailed out in advance of the investment in nuclear.
It is reasonable to have a many-year strategic reserve of uranium for what you need. A modern reactor is going to go through 20 tonnes of enriched fuel a year and they refuel every 18-24 months. 5-10 years of security and stability is much, much better than oil and gas.
> The same far-right country is also the one who wanted to cap the population because "there isn't room anymore", but I guess there is now room for massive nuclear plants and the storage of fuel and spent fuel shrugs
There isn't enough room in my house for anymore people but there's enough room for a new couch. How can these things both be true? Probably because the two have entirely different requirements and "there isn't room" is shorthand for many, many things.
Not saying they're right, this is just a bad counter-argument, especially since the alternatives all have the same problem.
> Nuclear will also boil over Swiss rivers and shallow lakes.
Yes, you need water capacity for cooling, about 2x as much as a gas plant for the same output. Definitely a trade-off. I don't know or care enough about Swiss water access to argue here.
The uranium-producing countries are Kazakhstan, Canada, and Namibia. There is zero chance that you cannot get one of those to sell to you.
> Nuclear will also boil over Swiss rivers and shallow lakes.
Wut?
What on earth are you talking about?
https://www.swissinfo.ch/eng/climate-adaptation/beznau-nucle...
It is far from boiling, but these limits are there to avoid killing all life in the rivers.
People aren't really partisan like that in Switzerland. They'll happily elect people from one party then vote against the party on specific issues in referendums or initiatives.
For something like nuclear, people who vote for green party might be mostly aligned with the party because it's a key issue for them while people who vote for center or right parties won't really care what the party recommends.
Unless you personally agree with whatever your preferred party's line is on everything and generalize that sentiment, I'm not sure how to get to that conclusion.
I don’t know why we put people in political buckets. It’s good to disagree. I am probably the weird guy but so be it.
I'd expect the strong anti movement from Germany to have some impact.
Of course people make jokes and remarks about "those people" who speak a different language. But "those people" are probably 1h away by train, are probably coworkers, and their language was taught in your school (even if some didn't bother to learn).
We also have a few language specific medias (German: NZZ, Tagesanzeiger, Blick, ..., French: Le Temps, 24 heures, La Liberté, ...), but I think most people consume Swiss media, especially when Swiss politics and local afairs are absolutely not covered by French and German medias.
We can't grow hydro at the required scale, and the usual problem with solar and wind (that we should develop nonetheless, don't get me wrong) apply: we can't produce enough power with those all year (winter nights need power too for heat pumps etc...)
The really awesome wind spots are more the coastal or offshore farms, which... well... we can't have (no access to the sea does that to you).
Solar is really really booming right now however, many houses take themselves off grid completely. Mine is a net producer for example.
Opposing nuclear & renewables is stupid. You need both. You need as many power sources as you can, as quick as you can while the resources are available. Energy is not something you leave up to the invisible hand of the market hoping that price competitiveness means that it works well. Lives are at play.
Go fully renewable. Add batteries, like Google is doing. Just one example: https://pv-magazine-usa.com/2026/02/24/google-to-deploy-worl...
Why do you need both? It's possible to get 99.99% reliability with wind & solar & batteries & weather modelling. There are multiple ways to handle a week long dankelflaute without nuclear: overbuilding, continental scale distribution, lots of batteries, etc. All are cheaper than nuclear.
It's also virtually impossible to get more than 99.99% reliability out of any grid, even a nuclear dominated one. Local distribution has many single points of failure.
Not to mention the environmental damage from producing and disposing of batteries.
It gives the strange feeling that although they decided to create a country together they don't want to interact with each others unless absolutely necessary.
how does having less available space favor a bigger reactor?
and how is constructing a bigger reactor faster than constructing a smaller one?
For small quantities, the former is usually more effective -- making things bigger lets you make fewer of them, reducing costs.
For large quantities, a factory can enable insane economies of scale.
SMR proponents are talking about building dozens of reactors. That fits very firmly in the "small quantity" column where economies of scale almost always favor building things bigger.
If a big nuclear reactor takes 10x more space but has 20x more capacity, then it means not having much space favors the big nuclear reactor rather than building 10 small ones that will take twice more space.
(and same for the time)
just picking random numbers:
i have 1 square mile available. a big reactor takes 4 square miles. i cannot fit a big reactor, despite the bigger reactor being more efficient.
As for speed, a 100 MW reactor is not commissioned in 1/5 of the time a 500 MW reactor is.
If the whole developed world had nuclearized the way France did, our discussions about climate change would be entirely different. We would have decades more runway to avoid 2C+ scenarios. We would have already electrified vast swaths of the economy, like home heating. We’d have extremely mature technology to give to developing countries that need massive baseload for industrial production. Today, we’d be discussing how many older nukes we could retire and replace with wind and solar plants.
So, where is the free market shitting out nuclear power? Anywhere?
Nuclear has never been financially viable and to the degree there has been “environmental” opposition it’s been NIMBY opposition to either the siting of the reactors or the siting of the disposal.
But again, the primary reason no one is building nuclear is because it’s incredibly expensive.
We stopped building nuclear reactors in the early 1970ies[0], long before there was any large organized civil movement organizing against it - because with the required additional complexity to make them safe, the technology was just too expensive.
(As always - it's the capitalists that messed things up, not civil society.)
Despite having 70 years of progress, nuclear today is more expensive than ever. It just doesn't scale.
France's nuclear operator EDF is €50 billion in debt. They make about €3 billion per year - and have between €150 - €200 billion investments on the table for the next 10 years. Go figure.

Who are we to begrudge a man his decade-long windmills-tilting: https://hn.algolia.com/?dateRange=all&page=0&prefix=true&que...
Those regulations you despise were written in blood.
Moreover, Nuclear power enjoys free catastrophe insurance. If a Fukushima style meltdown happens, the taxpayer is always on the hook for 95%+ of the cleanup costs.
So yeah, all you have to do is let them keep their freebie insurance, lavish them with subsidies and water down the regulations which make it vastly more likely that they'll need to use it.
Or just build some solar, some wind and some storage, save a mountain of cash and have new generation projects take under five years to finish instead of more than 20.
An apt reference. In both India and China it was the Fukushima disaster that spurred protests and stalled nuclear power growth. Organized environmental activism in both countries is basically nonexistent.
I would rank US-led nonproliferation policies above environmental activism as a cause for slow nuclear adoption as well. (Nonproliferation was primarily a military objective, by the way, not an environmentalist one.) Many countries only have nuclear power programs because France decided to occasionally proliferate them, many times over US objections.
They’ve been amazing for us, despite the fact that some of them was recklessly shutdown prematurely by an ignorant political class.
We stopped building nuclear reactors in the 1970ies[0] because with the additional complexity to make them safe, the systems were just too expensive.
It has nothing to do with "relentless irrational opposition".

For the renewables "Fast and cheap" turns out to mean you get the paperwork in the winter and you build a solar farm that summer, it's not quite sowing wheat - teams of competent people building the farm isn't the same thing as just chucking the seeds into the dirt with a machine, but the timeframe isn't so different.
Sweden's nuclear plants seem to have taken maybe 6+ years from breaking ground (not paperwork) to first power, so if you begin today you might have a plant in 2032 at the earliest. I can't see any prices, not even a CfD strike price for Sweden's new proposed plants.
The UK agreed £92.50 strike price (2012 prices) for the new nukes it may never actually receive, but unlike Sweden the UK has never pledged to relinquish nuclear weapons so to some extent having a native "nuclear" capability is relevant to national security.
2. Nuclear was built at a time when governments were much more likely to directly invest in energy projects. It didn’t have to compete with Labubus for private dollars.
3. Its current competition didn’t exist, given how much cheaper solar and wind have gotten, and how much cheaper battery tech has gotten with signs all of them will only get even cheaper. And on the non renewable side, natural gas has become incredibly cheaper as well.
2. Once the vote is there(Switzerland is a direct democracy), the public funds will be there. Sweden has recently chosen to invest ~40B Euro.
3. Solar, really? In Switzerland? Many parts of the industrialised world receive very little sun, especially in winter, where coincidentally, energy usage peaks.
And intermittent power generation like wind is no competition to nuclear.
These are very weak arguments. Good luck replacing Oskarshamn with solar panels…
It is a hard sell when you have to front a good chunk of money, without a track record of successful build ups. It applies to other infrastructure stuff like HSR.
Let’s hope Switzerland takes the lead here, Sweden are already building.
The political will is there. Let’s do it?
Most non nuclear powers have a few for the same reason Iran does: having some nuclear scientists and a developed nuclear industry around is handy in case of a, uh, geopolitical "emergency". This is why Poland suddenly became interested in 2023 specifically.
Most countries do not want a lot though - it's too expensive.
