After having read Gates’ latest book on climate change, one metaphor that stuck with me was the one on nuclear energy. It’s as if the Wright brothers invented the first airplane, flew off, crashed, lost every passenger, and then we collectively dropped the entire technology and every promise it held. Never to be visited again. Humans are weird.

(and I know the accidents were worse, but we iterated on car and plane safety, so why not energy safety?)

Re:EU experts to say nuclear power qualifies for green inves... by dijit on Saturday March 27, 2021 @02:13PM (#26604181)
It's worse than that.

It's like they succeeded and then many decades later flight MH17 happened and the world collectively lost its mind and declared air travel as inherently unsafe and condemned all research into it as dangerous.

The issue though, is that energy production is mostly quiet unless there's a problem, but people do see personal benefit in air travel.

Add to that: Coal is a silent killer, it's not obvious that it's killing us and in such numbers as it is. Nuclear is a dramatic killer, when we die from radiation it's clear and obvious and horrific.

Re:EU experts to say nuclear power qualifies for green inves... by Haemm0r on Saturday March 27, 2021 @02:26PM (#26604280)
The comparison of a happening with basically no longterm consequences to future generations like MH17 to nuclear fallout / necessary waste treatment is quite lame imho.

Nuclear energy without subsidies is not sustainable at all. Just do the math if you need decades to dismantle and decontaminate an old nuclear power plant alone.

> Nuclear energy without subsidies is not sustainable at all

And yet we seem to be doing just that here in Finland. The for profit companies operating and building the plants have been trying to get permits to build more (and very likely are going to get another one soon). Even with the "failure" of Olkiluoto 3 they seem to find a way to do it in a profitable enough way that they (2 companies TVO and Fennovoima) want to build more.

There are no subsidies for nuclear power at all in Finland.

Also our permanent spent fuel storage site is almost finished and should hold around 100 years of spent fuel. Though there have been now some talks to not really use it for most fuel as it makes more sense to build breeder reactors and just burn that fuel into much smaller amount. If that happens it will fit much more then 100 year of spent fuel.

This reactor?

>This month, the Olkiluoto 3 nuclear power plant in Finland was supposed to start producing power. Instead, the plant is at least three and a half years late and more than 50 percent over-budget. Olkiluoto was to be the “poster child” for the new generation of nuclear power plant designs that would drive the “Nuclear Renaissance” and if any nuclear project was going to go well. Instead, it has become an example of all that can go wrong in economic terms with new reactors. The vendor (Areva NP) and the utility are in bitter dispute over who will bear the cost overruns and there is a real risk now that the utility will default.

There does seem to be another reactor being built in Finland, but it's being built by Russia.

With the contract TVO signed with Siemens and Areva for the plant they will never end up having to pay all the cost overruns. It was basically a fixed price contract.

What ended up happening is Siemens got the fuck out of the deal (it was originally a Siemens and Areva joint project) and French government broke up Areva Group into smaller entities and took a hit on the failed project. From the legal fighting Areva agreed to pay TVO 450 million due to failing to deliver on time with some extra money going one way or another based on if it will deliver in the new revised timelines (ended up Areva having to pay TVO another 450 million).

According to TVO at the end of the day the project cost them 5 billion instead of the original 3.2 billion with Areva saying it cost the 8.5 billion so Areva took a huge hit on making a bad contract and/or failing to deliver.

Re:EU experts to say nuclear power qualifies for green inves... by rhodozelia on Saturday March 27, 2021 @03:58PM (#26605097)
What’s your point other than people generally sell large projects with a low up front number and it ends up being higher. Investors don’t get the 3-4x return they wanted and have to settle for 2x. Or it takes longer to pay itself back.

Solar and wind are expensive too if they are overbuilt 5x or backed up with enough batteries to be a firm source of power.

How can anyone argue against nuclear being part of the solution of reducing carbon emissions just because it takes more imaginary monetary tokens to build?

Who cares who is building the reactor? Russia and China have the skill and the will to make it happen while everyone else is wringing their hands and continuing to pump out co2.

Re:EU experts to say nuclear power qualifies for green inves... by corty on Saturday March 27, 2021 @04:06PM (#26605163)
Finland seems to have gotten the prototype, the same reactor type has been finished in China, twice: https://de.wikipedia.org/wiki/Kernkraftwerk_Taishan

However, also 50% over budget.

Re:EU experts to say nuclear power qualifies for green inves... by Haemm0r on Saturday March 27, 2021 @03:23PM (#26604768)
Where is the money coming from for the mentioned reactor? According to the wikipedia page a lot of French money is involved of a company connected to the French state.. edit: A breeder would for sure be a good way to reduce waste as you said..
Re:EU experts to say nuclear power qualifies for green inves... by doikor on Saturday March 27, 2021 @03:43PM (#26604969)
For Olkiluoto 3 TVO got the original 3.2 billion from its owners and some loans. And it was a fixed price contract but TVO has given into Areva a bit and is now projecting that it will cost them 5 billion. Areva at the moment projects the total price to be 8.5 billion so they will be taking a loss on it (who is going to pay what part of the overruns was in some courts at one point haven't really followed up if there was some verdict and what it was)

Funnily enough most of these loans are from German banks and various export agencies backed by the French government. Even still all these loans were given at market rates so EU would not kill the project (Greenpeace etc did make a complaint to EU and a investigation was done)

This kind of seller arranging some part of the loans is very normal in large infrastructure projects like these.

The other new project I mentioned is Hanhiviki in which Rosatom won the bidding. Areva and Toshiba also left their bids but as I understand it Areva was thrown out due to their failure to deliver Olkiluoto 3 in time/budget and Toshibas bid was not competetive. Though this Hanhikivi plant is still waiting for permits and there has been some obvious issues with it being built by Rosatom and the Russian sanctions going around. It also has some American and UK interests as Rosatom contracted the turbines to some GE subsidiary and Rolls Royce.

In British Columbia Canada we are building a 1000 MW hydro plant called site C for 10-12 billion. We have been doing studies on the site for 30+ years and it will be 10 years construction time by the time it is finished.

Nuclear looks pretty good in comparison.

FYI, oil & gas industry receives a lot of subsidies (just google it). On top of that, nuclear is extremely regulated compared to oil & gas. For instance, we have to capture and store nuclear waste. That's not the case for oil & gas CO2 waste.

> Nuclear energy without subsidies is not sustainable at all.

This is nonsense. We are basically using 60s technology that has some of these problems.

A modern reactor facility could be 10-50x smaller for the same output and that makes think like decontamination cheaper as well. Also, these facilities can run 100 years potentially, so the amount of money required for decommissioning is amortized of gigantic amounts of energy.

There is nothing inherent in nuclear that make it super expensive or unsustainable.

Interesting historical perspective since bomb planes transformed human warfare and was critical in the development of first ww1 and then more so during ww2. While not fully unique, the idea of killing the morale of the citizens rather than confronting the military was an insight many leader found from the bomb planes, and the idea of nuclear bombs are almost impossible without the idea of air travel.

As far as I know there are also economic problems with nuclear. Nuclear power plants are enormous investments, then take decades to build and eventually decomission. If renewable energy gets efficient enough, nuclear is not worth the effort.
Re:EU experts to say nuclear power qualifies for green inves... by lokimedes on Saturday March 27, 2021 @02:30PM (#26604314)
It’s actually pretty easy to build a nuclear reactor, but is as expensive to make it safe today as it is to maintain a Windows NT 4.0 server in 2021 when it comes to making it regulatory compliant.

Also when comparing nuclear to “renewable” energy, you are really comparing distributed low density investments with monolithic ones. Nuclear is 1e6 the energy density of chemical reactions. And wind/solar is basically heat exchangers positioned 8 light minutes from the nuclear reactor. The Sun incidentally, is just as renewable as that Uranium we are discussing.

What really boggles my physicist brain is how we expect a bunch of volatile solar and wind stitched together with fragile infrastructure and lithium piles to ever become a stable base load alternative. I put my hope on the Engineers knowing better than me :)

> What really boggles my physicist brain is how we expect a bunch of volatile solar and wind stitched together with fragile infrastructure and lithium piles to ever become a stable base load alternative. I put my hope on the Engineers knowing better than me :)

I don't work in this field, but I'd have a bunch of basic assumption you could dismantle:

1. We need a solid power grid, anyway, you know, for transporting electricity where it's needed. So shouldn't that stitching be quite solid anyway? Also, at a national level, I'd imagine solar and wind probably have rather solid statistical patterns, and those random factors can be abstracted away to a degree (the whole "what happens when the wind is not blowing?" - kind of hard to have the wind stop blowing all over 300k sqkm, all at once :-) ).

2. Once that power grid is solid, does it matter how small and distributed those solar and wind patches are?

3. I don't think Lithium-Ion is the only/main energy storage tech being investigated/invested in for grid purposes. And why couldn't it become a solid alternative for base load? Are base load-capacity energy storage facilities not competitive with gas/nuclear/coal power plants, factoring in pollution or other risks?

Re:EU experts to say nuclear power qualifies for green inves... by rhodozelia on Saturday March 27, 2021 @04:03PM (#26605132)
Imagine how overbuilt and under utilized a communications network would have to be in order for it to work the same way people imagine solar and wind power can be transported across the country.

Networks offer the best return on investment when they are fully utilized not sitting idle.

Re:EU experts to say nuclear power qualifies for green inves... by oblio on Monday March 29, 2021 @04:04AM (#26618748)
Aren't communication networks also overbuilt and underutilized ? After all that's why retail ISPs oversubscribe so much, and why we had issues at the start of the lockdowns.

If anything, communication networks are even spikier, which means that they need to be more overprovisioned than a power grid.

Re:EU experts to say nuclear power qualifies for green inves... by pitaj on Saturday March 27, 2021 @02:23PM (#26604258)
The economic problems are tied directly to policy problems, like the broken regulatory structure. For instance, as I understand it, a nuclear plant that began construction 10 years ago and is ready to go online by the standards when it began construction has to comply with all regulations created since. This makes creating new plants very expensive.

Doubt it. https://www.greentechmedia.com/articles/read/mit-study-lays-...

> It turns out that the main reason for spiraling nuclear plant construction bills is soft costs, the indirect expenses related to activities such as engineering design, purchasing, planning, scheduling and — ironically — estimating and cost control.

> These indirect expenses accounted for 72 percent of the increase seen in reactor construction costs between 1976 and 1987, a period in which the amount of money needed for containment buildings rose by almost 118 percent.

Re:EU experts to say nuclear power qualifies for green inves... by gcheong on Saturday March 27, 2021 @02:29PM (#26604301)
It would depend heavily on the reactor design. Smaller more modularized reactors can probably be built much cheaper with economies of scale by widespread installation. Renewables have hard limits as to how efficient they can ever be and they started out expensive too and heavily subsidized by government.
Re:EU experts to say nuclear power qualifies for green inves... by pydry on Saturday March 27, 2021 @02:22PM (#26604246)
This is the real issue. It's 3x as expensive as other renewables. Every dollar of subsidy producing 1 MWh of nuclear could provide 3 MWh of solar or wind.

Added to which, being a baseload power source is not nearly as useful as being dispatchable (like hydro and natural gas are), and it's insanely capital intensive (which leads to cost overruns - see hinkley point c, corruption & fat profit margins).

It's got real lobbying muscle though, especially from defense and military.

Re:EU experts to say nuclear power qualifies for green inves... by VBprogrammer on Saturday March 27, 2021 @03:14PM (#26604674)

Re:EU experts to say nuclear power qualifies for green inves... by pydry on Saturday March 27, 2021 @03:27PM (#26604812)
Do you disagree with Wikipedia's definition?

"Dispatchable plants have varying startup times. The fastest plants to dispatch are hydroelectric power plants and natural gas power plants. For example, the 1,728 MW Dinorwig pumped storage power plant can reach full output in 16 seconds.[4] Although theoretically dispatchable, coal and nuclear thermal plants are designed to run as base load power plants and may take hours or sometimes days to cycle off and then back on again."

https://en.wikipedia.org/wiki/Dispatchable_generation

Re:EU experts to say nuclear power qualifies for green inves... by VBprogrammer on Saturday March 27, 2021 @04:32PM (#26605383)
From the same article:

"Dispatchable generation refers to sources of electricity that can be dispatched on demand at the request of power grid operators, according to market needs. Dispatchable generators can adjust their power output according to an order.[1] Non-dispatchable renewable energy sources such as wind power and solar photovoltaic (PV) power cannot be controlled by operators."

https://www.nmppenergy.org/feature/dispatchable%20resources

"Dispatchable fuel resources include nuclear, coal and natural gas. These fuel sources are highly reliable because each fuel is a constant supply. These are known as baseload resources."

https://world-nuclear-news.org/Articles/Nuclear-stands-out-a...

"Nuclear stands out as clean, dispatchable firm power, says Kwarteng"

You are confusing dispatchable with flexible.

>Dispatchable generation refers to sources of electricity that can be dispatched on demand at the request of power grid operators

Precisely. It's not "on demand" if it takes a day to ramp up production and another day to ramp it down. It's on yesterday's demand, which is f***ing useless.

This contrasts with gas peaker plants which can scale up in seconds. These are known as "dispatchable".

>Nuclear stands out as clean, dispatchable firm power, says Kwarteng

Quoting an offhand comment from an idiotic energy minister trying to justify a boondoggle plant on a nuclear propaganda website isn't as convincing as you seem to think it is.

>You are confusing dispatchable with flexible.

You are confusing baseload with dispatchable.

Re:EU experts to say nuclear power qualifies for green inves... by VBprogrammer on Saturday March 27, 2021 @07:54PM (#26606753)
On demand doesn't mean instantly. Even gas peaker plants aren't instant, they can take 15 minutes to warm up and connect to the grid.

If the sun is down no amount of calling up a solar farm will increase output, if the wind isn't blowing or if it's blowing too strongly no amount of pleading will increase the output of an off-shore wind farm. This is because they aren't dispatchable. This is not the case with Nuclear.

Nuclear can do load following, they do it in France. How else do you think they balance a grid which has 70% Nuclear? They use reactors with grey rods which can reduce the reactivity in the reactor without distorting the shape of the reaction.

Actually many countries have developed nuclear technology in various forms over decades. The current latest generation of nuclear power plants (like the French EPR) is simply not cost effective. The Russian technology is nothing which would ever have a change to be deployed in a western country, due to its lower technical standards... Russia can't actually clean up its own nuclear installations.

Considering that the Hindenberg was destroyed by a bomb sneaked on board, the analogy is pretty good. The flames seen in the film were kerosene fuel ignited by the bomb. Humans have a way of causing their own disasters, when technical risks fail to deliver.

And, more than 2/3 aboard at the time survived. Hard to say where this fits into any proposed analogy.

Re:EU experts to say nuclear power qualifies for green inves... by makomk on Saturday March 27, 2021 @02:40PM (#26604398)
The actual answer is that we did improve on nuclear safety, and that all the regulations required to - for example - make sure that power plant designers didn't route all the redundant monitoring and control wiring down the same cableways and stuff them full of highly flammable foam are part of the reason nuclear power has become increasingly unaffordable. This is not some hypothetical example I'm making up, nuclear power plants in the US really did do that with predictable results and apparently the fire safety regulations really are a major cost. The Trump administration tried to fix this by giving more flexibility to designers, but of course that just made it proportionally harder to show the designs were safe and achieved nothing.

Because of this, one common refrain from nuclear proponents on HN is that we should just get rid of all those safety regulations and go back to 70s-era levels of nuclear safety because it's safe enough, which would be like if we'd just accepted planes were unsafe back when accidents were more common and not tried to fix it. It also misses one of the key lessons of airplane safety: this kind of normalization of deviance is a major cause of serious accidents. For every major disaster, there is a chain of less serious incidents where things just didn't happen to align right to cause lots of deaths, until one day they did... and nuclear power has the potential for some really impressive disasters. It also probably wouldn't be enough to make nuclear power viable again; it has a lot of cost problems.

It's an emotional response though, like how there are still more people with a parallizing fear of flight that don't have a problem hopping into a car.

Like I said, I'm not justifying being against Nuclear, but explaining the challenge with Nuclear's general acceptance, there is a fear response from people, and it'll need to be curbed and addressed. That fear response is due to the grandiose nature of a Nuclear failure which fossil fuel don't have, even if they kill you slowly and might lead to world ending catastrophies.
