In the end it seems the pro nuclear, and indirectly anti-renewables, argument seems to boil to renewables being a socialist conspiracy to sabotage the Western economy and society or something like that.
> I don't know any pro-nuclear that is anti-renewables. We see nuclear as an alternative to burning coal, gas or oil, not to renewables.
We have a ton of these people in Germany. "Technologieoffen" they call themselves - the reality is that they want to keep the old structure of big utilities and massive profits for shareholders alive.
> Renewables are great. We all love them. It's just that they are not here just yet, not 24h/day 265days/year anyway. They need a complement.
That's what a grid is for. Build a national grid with serious transfer capacities (China can do it over 1000s of km's, so the US can just as well if it wanted), and suddenly you can use East Coast solar to power the West Coast. Or here in Europe, with French and Portuguese offshore wind and solar from Northern Africa. On top of that, incentivise large consumers (data centers, heavy industry) to upgrade their processes to be able to handle dynamic load shedding, and invest into powerful gas and hydrogen fuel cell based peaker plants to cover for the very small amount in a year where neither solar, wind nor dammed hydro is enough to supply the entire country.
The serious issue with nuclear is that they cost billions of dollars to build. At the moment, in Germany 44% of the total power is generated using renewables [1], in peak times (i.e. summer) renewables account for up to 70% of the month's load [2]. The investment for NPPs can't ever be recouped at that point, which is why even small scale projects such as NuScale got the boot [3]. No matter what the pro-nuclear crowd hopes, the free market has decided against it.
Nuclear is expensive because of overregulation. Hence no free market when it comes to building nuclear power plants, unfortunately. Otherwise we’d have a glut of safe electricity at amazingly low prices. Of course safety was the pretext for that overregulation but when such a complex technology has the lowest deaths per megawatt (except solar) [0] - maybe we can relax the rules a little.
I know about your suggestions and while they are all good ideas I just don’t see them widely implemented in reality for some reason. Maybe because they all require government intervention which is slow, expensive and prone to corruption from the fossil fuel lobby.
Meanwhile the non-renewable part of energy generation is made burning coal, gas and oil and spewing pollution and even radioactive particles in the air, pollution that kills millions every year. Also spewing CO2 causing climate change, e civilization-ending danger getting closer and harder to avoid.
No free market for nuclear? Interesting, but not true. Simoly kWh prices show that wind and solar were cheaper than Hinkley C already, what, 5 years ago? Since then, solar is getting cheaper every year.
On electricity markets, which in Europe only take variable coats into account, the ranking, cheapest to most expensive, is: wind and solar, hydro, coal, nuclear and oil followed by gas. So even there, in hard cold numbers, nuclear looses. Even without taking the huge fix costs of nuclear plants into account, or the long term coats like waste storage.
Why do you think even small, and potentially cheaper, reactor projects get axed?
> Nuclear is expensive because of overregulation. There is no free market when it comes to nuclear, unfortunately.
And for good reason. There is no power generation that has a potential for serious damage compared to nuclear. The cost of Chernobyl was at least 235 billion dollars [1], Fukushima is estimated to end up at around 200 billion dollars [2]. The only other kind of power generation that can destroy entire swaths of land in a single strike is dammed hydro, but even the largest catastrophe to date, the Kakhovka dam destruction in Ukraine, cost only 14 billion dollars [3] - and it didn't render the affected land permanently uninhabitable and only cost the lives of about 50 people, compared to Chernobyl's death toll.
It's utter madness to risk this much money and this much destruction when there are so many different ways of getting power. Nuclear power may be the cheapest per kWh on paper, but that is only because the worst-case risk is implicitly assumed by the government without accounting for it in insurance premiums - at least the major Western countries limit operator exposure to liability claims to a fraction of the potential cost [4]. This is beyond unsustainable, it's financial russian roulette.
We will not be able to live entirely without NPPs, I agree on that one, as we need them to create Co-60 for radiotherapy sources and the nuclear weapon powers to get new feedstock to maintain the warheads, but we should try as a species to get rid of nuclear weapons anyway and only keep the minimum we need for radiotherapy and fundamental research.
> There is no power generation that has a potential for serious damage compared to nuclear
Of course there is. Good old oil, coal and gas burning. Since we’re fear-mongering on potentials here, would you like to estimate the cost of a runaway green house effect that turns the whole Earth into Venus? Climate scientists are warning we may already be beyond that point of no return. And we are still putting CO2 into the atmosphere while arguing the “potential” dangers of nuclear!
> And we are still putting CO2 into the atmosphere while arguing the “potential” dangers of nuclear!
We're building renewable generation capacity at a far greater speed (as said, Germany alone > 1GW a month...) than we ever could using nuclear power. This in turn enables us to shift residential and commercial heating to heat pumps - even assuming a gas power plant, 1 kWh of electric power replaces 4 kWh of heat power.
I totally forgot that now insurance, or re-insurance company is willing to insure against that risk. I am sure that is because those companies a anti-nuclear environmentalists and it has nothing to do with their risk models showing nuclear power plants to be uninsurable from a risk / profit perspective.
There we agree. There is only one problem: nobody wants to build new nuclear reactors in the West, they are not competetive with renewables anymore. So every dollar invested in new nuclear reactors is a wasted dollar. The fossil fuel lobby benegits largely from that, because every dollar going into nuclear projects, which will be completed at least a decade later if not more, is a dollar not going into renewables going online in the next year. And it is the latter that posses a problem for fossil fuel plants, not the former.
Anyway, as with EVs, capitalism has decided: wind and solar it is, that's where the money goes and not nuclear. For mostly the same reasons come 2030 you wont be able to buy ICE cars anymore. Profits and money.
I'm expecting the automotive industry will just start producing vehicles that aren't effected by that requirement and those will be marketed in much the same way as SUVs have become pretty much the only vehicle type available because they're permitted to emmit more CO2.
Yes, free markets have fuelled a technological boom that delivered us renewables - an incredible, completely unexpected feat. But it may be a case of too little too late.
The problem is we spent last 100 years spewing CO2 into the atmosphere instead of switching to nuclear due to the nuclear fear-mongering from environmentalists. Now we are facing Climate Change, a civilization-ending danger. And I am not sure the renewable build-up is fast enough to replace hydrocarbon burning, especially since it also has an availability problem.
The rational strategy would thus be a (slow, controlled, careful) cost-reducing deregulation and nuclear buildup in parallel with renewables and closing down of legacy plants.
But we are facing the same resistance and fear mongering from the exact same politicians and ideologues that got us into this predicament in the first place. I am pretty sure no solution can come from the same people and way of thinking that created the problem.
Fun fact: Free markets have not a lot to do with the technological leap of solar, that was mostly German subsidies for PV. In the end only Chinese companies benegited from that, but that is a different topic.
Nobody, I repeat nobody, is financing new nuclear reactors in the developed world (except specialized and military applications). The money goes, for quote a while now, into renewables and, sadly, some coal plants (which is mainly due to CO2 certificates being too dirt cheap, and making coal plants financially viable). The free market and financials decided against nuclear, as did politics in a lot of countries.
One thing you do ignore so, getting new nuclear reactors up and running takes decades in Europe, there is no such thing as a fast built out. Not even if the public and political will would be there, which it isn't. All we do achieve with argueing for new nuclear capacity is slowing the build out of wind and solar down and slow development of grid scale storage tech.
>The free market and financials decided against nuclear
I'm just trying to fully understand the position here. How do you mean "free market"? Because it seems a disproportionate amount of nuclear cost is driven by regulation. I'm not even saying that unwarranted, but it certainly seems to be very different from the colloquial definition of a "free market".
"It seems" is usually not true. Sure, nuclear is regulated. As are all other forms of electricity generation. As usual, regulation is written in blood, or in the case of nuclear three figure billions of clean-up costs after Chernobyl and Fukushima.
Regulation, I might remind you, that was written by staunchly pro-nuclear organizations.
Also, just necause you have regulations doesn't mean you don't have a free market. Hence, there is a free market for nuclear electricity. Thing is, nobody wants to finance new projects (with the exception of developing countries, but those have a lot of catching up to do).
One cost nuclear power plants do not have to carry is insurance against large accidents. No insurance comoany would take on said risk, hence the state is carrying that risk. Soubds to me like a huge cost factor is taken off from nuclear power plant operators here (just to pick one example).
As said elsewhere, I'm all for keeping existing NPPs running as long as safely possible (which was the reason Germany had to shut down a couple), and shut down coal plants instead. Building new NPPs takes too long to be a viable solution, and is too expensive (and hence the lack of fubding for new ones).
> Free markets have not a lot to do with the technological leap of solar, that was mostly German subsidies
The technology used to make solar panels is the same used for semiconductors. It evolved al Moore's law speed thanks to an unregulated free market for the tech industry. Same reason we enjoy a cheap supercomputer in every pocket in 2023 instead of the city’s Eniac. That’s what lack of regulation does.
What German guvernamental subsidies did was to build a lot of Solar capacity in a country with relatively little sun. I hope it works out for them, but I remember earlier this year importing nuclear electricity from France.
> And I am not sure the renewable build-up is fast enough to replace hydrocarbon burning, especially since it also has an availability problem.
It absolutely is. Germany is building about 1.5GW a month of solar and wind combined, so over a year the equivalent of a dozen average large scale NPPs.
Even accounting for the availability problem, aka capacity factor (wind ~0.3-0.5, solar .25), that's the equivalent of four NPPs a year. The rest? Can easily be covered with a combination of hydro, geothermal, massive grids and dynamic load management (both on the demand side aka load shedding and on the source side aka powerwalls with feedback capability).
> Germany is building about 1.5GW a month of solar and wind
I root for them to succeed. I do love renewables. But I know that in my country at least the waiting time today for panel purchase, installation and grid connection is over a year. However they are subsidized by the state so that adds time and bureaucracy.
The rest… I have my doubts: it’s all ideas but little reality. We’ll see in about 5 years time, I guess.
Meh, a lot of heavy industry is still running on machines from the 60s. Incentivising them to upgrade their old crap to modern times would cost them billions (which is why they've been dragging their arses so long), but it would bring a lot of consumption savings and flexibility to the grid.
Renewables are great. We all love them. It's just that they are not here just yet, not 24h/day 265days/year anyway. They need a complement.
