The new Korean plants are designed for a lifespan of 60 years.

If governments provide guarantees for the loans, a discount rate of 3% is not unreasonable.

Set it like that, and it spits out a price of €32.6/MWh.

Now, to make it even more reasonable to emerging economies, assume that through mass production and a relaxation of security requirements to less paranoid levels, the overnight cost can be reduced to €1500, you get $21.3/MWh.

This is what the price of electricity SHOULD be, if we want the world to stop depending on hydrocarbons. (Not just a few rich countries.)

When your argument depends on all existing trends reversing, that tells us all we need to know about your conclusion.

You seem to ignore the fact that existing trends were artificially manipulated to suppress the nuclear energy use.

"The fact". I think not.

There is an abundance of data, if one is willing to look. Just first links from DDG:

"Has Russia Been Financing Western Environmentalism?" (2022) [1]

This is a load of conspiracy theoretic BS, starting from the nonsense position that environmental groups are the source of nuclear's failure.

Yeah right, "Independent fact-checkers said the information is false".

The greens in Germany have consistently worked on destroying Germany's nuclear energy generation, and now it is completely dependent on gas import from Russia, funding Putin's war with Ukraine.

I can fully agree that green groups have opposed nuclear.

I call bullshit on the absurd idea that the global failure of nuclear is due to these groups.

I can hardly call nuclear energy to be a 'global failure'. True, 'green' groups had some success with scaremongering people to be afraid of nuclear energy, but it is generating 10% of energy globally (projected to rise to 15% by 2030 [1] ), with much higher shares in developed countries. If anything, the Fukushima effect has finally weared out, and we'll see new plants constructed which were halted because of that scaremongering.

Well, it obviously is a global failure. It exists in places where people can be forced to pay for it. There is not a single competitive energy market where merchant nuclear reactors have been built to compete in that market. That's because it's just too expensive. Sure, reactors have been built to exploit monopolies, and where political considerations trump economic ones. That's nothing to be proud of.

Just because you repeat it again and again, and use the word "obvious", nuclear power does not become a 'global failure'. I fail to see any arguments in your posts, just NUCLEAR BAD slogans.

See, this is why nobody trusts nuke advocates.

Trends and fashions come and go. My daughter is wearing pants that look that the ones my mother wore some years before I was born. At that time, nuclear power was still popular. And now, perhaps, it is becoming so again.

Indeed, the NYT article in the topic is discussing this very question.

Nukes get less competitive with each passing day. But that does not keep shills out of the NYT's pages. Fortunately actual investment does not follow shills.

Tell that to France, those losers still generate 70% of energy with nuclear plants, instead of following the lead of their German colleagues in denuclearizing their energy grid.

Yet, France has no plans to build replacements for the large majority of plants soon to age out. What they will build is purely politically motivated. Those probably will not be completed, as they would be uncompetitive, but ratepayers might be forced to make them profitable by paying way more for power than their neighbors.

Germany elected to build out a great deal of wind generation capacity rather than refurbish a much smaller capacity of aged, ramshackle nukes. That has worked out extremely well, and they continue.

> Germany elected to build out a great deal of wind generation capacity rather than refurbish a much smaller capacity of aged, ramshackle nukes. That has worked out extremely well, and they continue.

Really? It has worked really well?? Thanks to these really well policies, Germany has an unbreakable dependence on Russian has [1] and has paid billions of euros to Putin's murderous regime since the start of the war with Ukraine [2].

If this is 'really well', I'd rather pass.

In conclusion, I suggest you start looking more rationally on energy generation, I sense a lot of anger and unexplained hatred towards nuclear power ('aged, ramshackle nukes' is not a rational sensible argumentation).

Germany was dependent on fossil imports all along. What has changed is they import less, now, than when they ran the nukes. They will import decreasing amounts as they build out more renewables.

It is a fact that the nukes shut down would have needed a great deal of expensive work to continue operating. Germany elected to spend the money on wind, instead, and it bought them more actually delivered wattage than the shut-down nukes had provided.

If nukes were not the most expensive power source going, I would be all for it.

Are you really arguing that they'd import more gas now if they hadn't shut down the nuclear plants?

Everyone including Germans have understood by now that phasing out nuclear was a mistake, but you still repeat that no, gas dependency good, nuclear power independence bad.

Yes. They would be importing more fossil fuels now if they had not built out wind, and had instead spent the money on their reactors.

If they hadn't destroyed their nuclear generation AND created wind&solar, etc, they wouldn't have to import anything from Russia.

For some reason, you (incorrectly) presume that maintaining nuclear energy prevents building wind generators. Also, the money 'spent' on reactors is kinda paid off by customers who pay for the generated electricity.

Money is fungible. Each euro spent on one thing is a euro not spent on a different thing.

Electrical power is also fungible. A kWh delivered is a kWh, whether generated on a nuke or in a wind turbine.

That's overnight cost, not included in model.energy. You also have to add in the financing cost during construction.

If we are talking about Korean export NPPs, the Barakh NPP has four reactors for a total of 24.4B$, producing 5.6GW(e). THis is about $4B/GW. If I plug in 4000 per MW (its euros, not $, but they're not too different right now) for the capital cost of nuclear in model.energy, increase the NPP lifetime to 40 years, and use US 2011 weather data, nuclear optimizes to zero.

I'll add that model.energy is looking at the best case for nuclear: providing baseload. Handling variability will incentivize storage, which means renewables will be at an increased advantage. Dispatchable demand of any kind, even slightly dispatchable (allowed to be off 10% of the time, say) also tilts the game toward renewables.

The 25 year lifespan for nuclear there may reflect economic obsolescence rather than technical lifespan. Energy technology is evolving quickly now, so investors may simply refuse to credit the promise of such long lifespans. Even in the US, there have been existing NPPs that shut down because they could not recoup their operating costs (granted, much of that was due to gas and also renewable subsidies, but with solar having dropped in cost by nearly an order of magnitude in the last decade it's a bold move to assume it won't keep falling.)

Do the same and use German data, and nuclear optimizes to 100%. The US has especially abundant wind and solar.

I would very much like to see a similar model that includes a demand curve. Preferably, customizable demand curves, to allow for modeling of e.g. flatter curves due to electric vehicle charging at night.

Yes, Europe (and particularly eastern Europe) are better places for nuclear, because of higher latitude and (away from coasts) lower winds.

This is all just delaying the crossing point though. Nuclear fans are betting nuclear's costs fall while renewables and storage run into brick walls and stop getting cheaper. It's not clear why one should assume this, or why an investor should bet on that outcome. And it is just a financial bet; in the worst case for renewables they just come in a bit more expensive than nuclear, so it's not like the economy explodes.

Ok, but "I think renewables will get cheaper faster than nuclear" is a very different claim than "renewables are way cheaper than nuclear right now."

It's a different claim. It's looking at trends rather than at a specific point.

Solar historically declines in cost by 24% for each cumulative doubling of production (of the solar hardware). Solar is about 4% of global electricity production now, so scaling it to saturation (just for current electricity demand, which will grow as the world becomes richer and more electrification replaces fossil heat) would drop the cost by another factor of 3.

> Solar historically declines in cost by 24% for each cumulative doubling of production

This only worked while panels were the lion's share of the cost of a solar installation. These days, costs of real estate, installation and grid connection far exceed the cost of panels -- and those costs go up every year with labour costs rather than coming down.

Costs of installation only go up? There has been steady improvement there, particularly at utility scale. No more expensive poured concrete foundations, just screw earth anchors into the ground.

Or are you talking labor-intensive installation onto residential rooftops? Well, stop doing that, it's kind of stupid.

Real estate costs are a tiny fraction of the cost of installed solar in much of the US, and in much of the world. A solar powered global economy will not be putting many panels on the small fraction of the world's surface that's unusually expensive, but will focus those panels on places where it's cheaper. It's the same reason we don't grow wheat in Manhattan.

model.energy assumes a flat, constant energy demand.

Which isn't a ridiculous assumption, given their caveats and default options, unless you're trying to argue for 100% nuclear, in which case it renders any conclusion totally nonsensical.

I would really like to see a model that includes demand curves. Or an academic study that includes nuclear as a possibility, instead of just looking at wind/solar/storage. So far I haven't come across either.

(But if we start charging a lot of electric vehicles at night, the demand curves will flatten out anyway.)
