Nuclear energy key to decarbonising Europe, says EESC

Nuclear Energy is incredibly expensive and has a lot of other issues like long term waste storage. It's arguably better than Coal and Gas but the KEY to decarbonisation is and always will be renewables. The Headline is rather misleading in that regard.

Anyways, solar is also cheaper

belorn•47m ago
As long there is no need to use gas during periods of non-optimal weather, then solar and wind is great.

The lithium battery plant in northern Sweden went bankrupt so its difficult to say how to solve the storage solution by both being cheap and financial viable. New battery solutions are being made, but in the end it need to be cheap enough over the long term. The current use of gas for non-optimal weather means prices jump up by a factor of around 100x of what it is during good weather, and the average price in nordpool (the northen pan-European power exchange) is about 20x than what you get with good weather. That should illustrate how much variability there is in the energy price right now, and how much people are paying for that gas powered electricity in periods of non-optimal weather conditions.

A lot of fossil fuel subsidies goes directly to support the high variability power grid, and they more than doubled during 2022 when the gas prices went up. It is incredibly expensive, likely more than nuclear, to have a grid supported by renewables during optimal weather conditions and fossil fuels during non-optimal weather conditions. It also generate a lot of waste in term of pollution which has a bigger issue both short and long term than nuclear waste.

jltsiren•2m ago
Nordpool prices are not true market prices, as much of the demand does not participate in the market. For example, many residential customers still have fixed-rate contracts, and some power companies sell the power they generate to their owners at cost price.
EricE•1h ago

DarkNova6•1h ago
So you want to create a completely new industry. From the ground. With all existing experts having retired. Demanding high quality, no-fault tolerance production. Dependent on resources not found in Europe.

Look, I love nuclear technology. But the world has moved on. The costs to rebuild this industry is astronomical and means we lose out on key-future technology like batteries.

Edit: But then there are bombs. And especially French love their nukes due national security. This is the only reason to keep pushing for nuclear, since Russia, the US and China are not gonna change direction on this either. But the very least we could do is be honest about it.

nixass•1h ago
> Look, I love nuclear technology. But the world has moved on.

Come again?

iknowstuff•55m ago
We deploy 10x the capacity in renewables and batteries than we do in nuclear and its only accelerating. We are trending towards 1/10th the cost of nuclear per GW. There is no going back just due to the sheer scale of mass manufacturing renewables.

We are below $1B/GW for solar. China just opened a $100/kWh ($100M/GWh) battery storage plant. All deployable within a year.

Contrast this to $16B/GW for recent nuclear plants, and you don’t benefit from starting a build for another 20 years

Ok let's link Germany when the sun is not shining and the wind is not blowing.

lawn•28m ago
You still need electricity when the sun isn't shining and the wind isn't blowing you know?
nixass•21m ago
You can move slider for last 24hrs, there were sunny bits in Germany. CO2 is constantly shit over here. And yeah.. what am I supposed to do when it's not sunny or no wind? Fart into windfarm?
Phil_Latio•13m ago
Then look at the the average and compare with France. Germany causes 6 times more Co2 stemming from energy production.

The energy mix in Germany leads to a situation where electric cars are dirtier than diesel (for the first ~200000 km / 125000 miles driven).

goatlover•52m ago
That's great, but what percentage of decarbonization will it stall at due to lack of energy density and relying on the wind/sun?
iknowstuff•40m ago
How is it stalling anything if it offers a cheaper and faster build than nuclear? If you need to build 1GW and want it anytime in the next 2 decades, you sure as hell don’t choose nuclear. You either do natural gas or renewables these days. Those are the only competitive sources of energy.
mpweiher•30m ago
You actually need energy even when the sun doesn't shine.

And you are incorrect: renewables are not competitive without heavy subsidies and preferential treatment, such as being allowed to shift the cost of their intermittency onto the reliable producers.

DarkNova6•20m ago
The problems lies in the lack of storage. Which is why you need efficient and scalable battery technologies. This is the true key technology that yields much more promise than anything nuclear.
mpweiher•33m ago
Since the capacity factor is so much lower, 10x in capacity just about matches the energy production of nuclear. Never mind the dispatchable power.

And since nuclear power plants last about 4x longer than renewables, you actually have to install 4x the production to have an equivalent fleet over time.

So by your numbers, the world is shifting towards a nuclear fleet.

iknowstuff•27m ago
Ugh. One of us is living in an alternate reality. If the share of energy produced is not growing increasingly more renewable, then it’s me.
solarengineer•10m ago
[delayed]
jandrewrogers•8m ago
That cost is a property of the regulatory environment, it isn't intrinsic.

You can buy a floating nuclear power plant in the form of an aircraft carrier for a lot less than $16B. The US Navy builds these things as a matter of course in a few years using standard designs they crank out by the dozens.

DarkNova6•21m ago
Look at the boom of nuclear in the 70s. The industry wide and deep expertise from production, to planning, to logistics. Particularly the french did this par excellence. But nuclear has first languished and is now almost non-existent in Europe.

Contrary to capitalist believe you cannot solve all issues fast by throwing unreasonable amounts of money at it. You must built industries that synergies with each other, have deep institutional knowledge and capable workers that can deliver the tiny tolerances required to make nuclear safe and effective.

We simply do not have the (intellectual) capacity for this anymore and the effort is better spent on battery technology if Europe actually wants to have any stake in future of EV and renewables. It is significantly less capital intense too.

goatlover•53m ago
But that means it's not a completely new industry since the French already have nuclear power plants and working experts.
DarkNova6•18m ago
Oh yeah, the EPR is going super great. Delay after delay after delay.

The Finnish EPR only took 18 years of construction. What a marvel of engineering and planning.

mpweiher•36m ago
Er...what?

There is a massive nuclear renaissance in-progress.

According to the following tracker:

https://globalenergymonitor.github.io/maps/trackers/nuclear/

There are currently 419 reactors in operation, 76 in construction, 140 in pre-construction and 290 planned/announced. I have a slightly older version of that chart, where those numbers were 69, 92 and 178, respectively.

Note that both the numbers are pretty large compared to the installed base (more than doubling the installed base), that they are increasing for the earlier stages (indicating more is in the pipeline than is currently being built), and that all the pipeline stages are increasing over time.

Which is of course consistent with the fact that 34 countries have now signed the international pledge to triple nuclear output that was first agreed at COP28. These countries include: France, the United States, China, Japan, Poland, Sweden, etc. India has plans and is on track to triple by 2032, but hasn't signed the pledge.

I am also not sure why you think that "all existing experts" have retired and there is no nuclear industry. The World Nuclear Exhibition in Paris November 4-6 of this year had over 1000 exhibitors, and more than half of those were from Europe.

https://www.framatome.com/en/evenements-clients/world-nuclea...

Even phase-out-Germany still has substantial nuclear engineering capacity, there's even a nuclear fuel factory in Lingen. And of course the actual nuclear component of a nuclear power plant is only around 20%. About the same effort/cost goes into the steam turbines, of which Siemens is a major worldwide supplier.

And of course civil nuclear programs have next to nothing to do with military nuclear programs. There are many more users of civil nuclear power than there are military nuclear powers, and the military nuclear powers invariably got the bomb first, and added a civil program later, with some like Israel only having a military nuclear program, not a civilian one.

In fact, there's a fun anecdote from the beginnings of the French nuclear program, since you mention France: when the Messmer plan got started, the military wanted to deploy an indigenous type of reactor for the civilian program that was more suitable for military uses, but in the end the government decided to standardize on a US Westinghouse pressurized water reactors that was not useful for military purposes.

sailingparrot•31m ago
> So you want to create a completely new industry. From the ground. With all existing experts having retired.

This is an article about Europe. Do you really believe France alone is operating 57 nuclear reactors, and producing 70% of its energy via fission, without the industry, the knowledge, and with no experts left? Is chatgpt running everything?

DarkNova6•25m ago
If you are so smug about this, answer me:

1: How man reactors were built in the 1970s and are nearing end-of-life?

2: How many reactors has Europe built since 2005?

3: What's the overrun time of reactors in Europe, compared to China?

The only reasonable conclusion to draw is that the industry has existed. It was world class, but the institutional knowledge to bring it back to this quality does not exist and would need to be rebuilt for the new generation of reactors. And we are not even talking Generation 4 here.

nine_k•7m ago
France in particular connected a new nuclear power station to the grid as late as 2024 [1]. But the previous reactor was put online in 1999 or so.

Three more were built in EU since 2000: one in Finland (Swedish/Finnish design) and two in Slovakia (Soviet/Russian design).

[1]: https://en.wikipedia.org/wiki/Flamanville_Nuclear_Power_Plan...

sailingparrot•1m ago
Yes, very few new NPP have been built in Europe recently. Quite a few have been built by Europe however. The french company Framatome alone, with 18k employees, is actively building 2 EPR reactors in the UK (+ preliminary studies for 8 more), multiple in China, India, Russia (although I guess that might be canceled).

Its also already operating the 57 french reactors as well as operating reactors in South Africa, China, Korea, Belgium, Finland.

Sure, the industry will need to grow, but claiming it basically has to start from 0 is ludicrous.

I think Fukushima rather than Chernobyl looms over us as a more realistic disaster that could happen again.

When you look at the data though, its political fallout was much worse than the actual toll on human life, etc. Fukushima released a small about of radiation into the environment. But modern reactors don’t have the same runaway reactivity flaws that Chernobyl did.

Not zero risk. But not the level of risk resulting in half a continent potentially being uninhabitable.

goatlover•50m ago
Would Chernobyl have realistically made half a continent uninhabitable had the Soviets not taken all measures to contain it? Or is it more worse case fear mongering nuclear has always had, while oil tankers s[ill into oceans, pipelines leak into national parks, people die from polluted air, and climate change continues to grow worse?
mandevil•13m ago
I mean, the basic problem at Chernobyl was the lack of a big heavy containment vessel that essentially all other reactor designs have. That containment vessel (and a couple of other design features, e.g. negative void coefficient in a PWR) has, so far, largely prevented Chernobyl like issues at other, better designed reactors. So far a TMI/Fukushima Dai Ichi/Chalk River is about the worst that has been observed in a reactor with a containment vessel.

And as for how realistic it was that it would make large areas unlivable, the threat was of a melt-down going far enough down to hit the water table and contaminating the groundwater. That would make large areas only livable if you brought your own water, even for bathing, basically making the area impracticable. Obviously it didn't happen, but I'm not clear whether it was a 0.5% chance, a 5% chance or a 50% chance.

BurningFrog•40m ago
Fukushima was the result of the biggest earthquake in 1000+ years of Japanese history occurring where the resulting tsunami knocked out the backup generators at the plant.

Such an extreme set of outlier events could happen again, of course, but it's not very realistic.

Here in Ontario, residentially we pay about 0.09 USD per kWh at night and 0.18 USD with demand peak pricing on weekday afternoons. Or if you have flat rate it's about 0.13 USD per kWh. This is considered very expensive by Canadian standards and it's due to our nuclear power program where about 55% of electricity is from nuclear, the rest from a mix of wind/hydro/solar/biofuel and gas. The increased price during the day is due to the need to burn a bit of gas at peak demand. The grid is otherwise nearly carbon neutral, and the long-term plan is to phase out the gas with a mix of wind, nuclear and pumped storage.

We pay less in practice than the rates given above for power, because the government also subsidizes it. But even without that I understand such rates would be relatively cheap in most European countries.

Is that the commercial price to the end customer with tax and connection fees, or is it the gross price at the power exchange?
nine_k•14m ago
End customer tariffs, I suppose. IDK if they include delivery.

Bulk prices at exchanges are way lower, like 2.2¢ per kWh: https://www.ieso.ca/Power-Data/Price-Overview/Ontario-Market...

retrac•11m ago
Consumer price of the energy. Doesn't include connection fees, but those are a minority of the cost. Includes special energy taxes. But not sales tax.

For a real example, I'm on flat rate and if I use 1000 kWh my monthly bill will be 211 CAD (effective rate 0.21 CAD / 0.13 EUR per kWh) including taxes, connection, delivery, everything, but without subsidy. The amount I pay after the subsidy is applied would be less at 165 CAD.

mrweasel•45m ago
Modern energi consumption confuses me. There has never been more wind and solar, coal fired plants are almost a thing of the past. Everything is becoming increasingly energy efficient, yet we produce more CO2?

Where is the fossile fuel being burnt?

iknowstuff•36m ago
Roughly, greenhouse gases are, a quarter from (animal) agriculture, quarter from energy, quarter from industry (cement/steel etc), and a quarter from transport.
mandevil•27m ago
Mostly, what you are seeing is that the half of the world living in the India-SEA-China circle [1] are living much better lives, which requires far more energy then living as subsistence farmers did. In the G7, CO2 emissions have declined (but not as fast as they need to stay below the 2C target) but the rest of the world is emitting more: during the negotiations for the Kyoto Accords in 1998 G7 countries produced about half of the world's CO2 and now they produce about a quarter. That's mostly because the rest of the world started emitting more and only a little because of drops in the amount produced by G7 countries.

There is obviously major ethical issues here. The rich, already developed world- having emitted enormous quantities of CO2 to get there- telling poor, undeveloped people living as subsistence farmers that they can't use any more energy because of all the CO2 already in the atmosphere is a really hard argument to make, locking them into being poor forever while the developed world benefits from all that CO2 consumption. But on the other hand, by skipping right to large scale solar, maybe those inside the circle can do a better job?

For some reason it took this long to hit me.

If you take as axioms:

1) Countries have major political interest in whether other countries have nuclear reactors

2) Countries are already, at large scale, manipulating discourse across the internet to achieve their political goals

Then of course it follows that any comment thread on a semi-popular or higher site about whether a country should build more nuclear reactors is going to be heavily manipulated by said countries. That's where (most) of the insane people in such threads are probably coming from.

How are we supposed to survive as a civilization with such corrupted channels of communication?

solarengineer•23m ago
I am a former nuclear opponent. I used to think that nuclear waste was glowing green like they show in the Simpsons and in the Doom 1 game. Once I had access to the Internet in this century, I learned better.

Here are some sources of information that helped me understand the two oft-cited nuclear disasters better.

The World Nuclear Energy write up on the Fukushima incident: https://world-nuclear.org/information-library/safety-and-sec...

Some information on the Chernobyl incident: The infographics show: https://www.youtube.com/watch?v=2uJhjqBz5Tk

https://world-nuclear.org/information-library/safety-and-sec...

A lecture in the MIT Courseware on the incident: https://www.youtube.com/watch?v=Ijst4g5KFN0

This lecture is way more informative where the professor explains how the workers took the system beyond the rated capacity as part of a test.

There have been many lessons learned, and the World Nuclear article linked above shares some of these.

Here is a writeup of the Three Mile Island incident: https://world-nuclear.org/Information-Library/Safety-and-Sec...

One regular complaint is the costs of nuclear energy. This is likely true in the US due to regulations that have not been revised for newer technology, but such high costs are cited around the world.

Likewise, the amount of waste and the danger of the waste is not well understood either, and certainly lots of education is needed here. For e.g., most people do not know that the volume of waste is limited and that the same waste can be reused in reactors of other designs.

I do believe that national ego issues get in the way of fixes. I believe that such ego issues got in the way of honest repairs (Fukushima) and timely action (Chernobyl). Certainly, nuclear inspections are still treated with suspicion and hostility, but in fact full transparency and integrity should be the norm.

Corruption and profit-centric thinking are two other problems that plague the nuclear industry. South Korea has had lots of corruption and shortcuts (https://www.technologyreview.com/2019/04/22/136020/how-greed...). One of the accusations in India against France was that France licenses outdated nuclear reactor technology despite having newer technology. I am unable to locate a link supporting this accusation.

With thorium reactors and Small Module Reactors, there are many modern solutions to safety.

ThorCon's Thorium Converter Reactor - Lars Jorgensen in Bali https://www.youtube.com/watch?v=oB1IrzDDI9g

Here is the full training by Thorcon on their reactors: https://www.youtube.com/watch?v=kkvEXm-rMW4&list=PLuGiwaUJYE...

We need to stop citing and quoting US-based costs and problems that are linked to outdated US regulations. There are other countries that have more modern regulations and modern technologies.
