“85% of used fuel rods can be recycled” is like “We can totally capture nearly all the carbon from burning fossil fuels and then remove the rest from the atmosphere by other means”.
In theory it’s correct. In reality it’s bullshit that will never happen because it’s completely uneconomical and it’s just used as an excuse to not use the affordable technology we already have available and keep burning fossil fuels.
While I understand where they’re coming from, it should be noted that they’re likely basing their experience with recyclability on plastic recycling which is totally a shit show. The big difference comes in when you realize that plastic is cheap as shit whereas uranium fuel rods are not.
Fossil fuel lobbyists know very well that their business model is running into a dead end. So now their goal is to extend it as long as possible.
Today’s fossil fuel propaganda isn’t “Climate change from CO₂ isn’t real” anymore. It’s “We can totally fix this with carbon capturing later”, “Renewables are actually bad for the environment” and “Better don’t build renewables now as a much better solution will be available soon™ <insert SMRs or any other fairy tale how new reactor will totally be cheap and not producing waste here>”. Yet it’s not happening. Nuclear is uneconomically expensive and produces toxic waste we actually don’t know how to handle safely for the amounts of time it stays toxic.
Nuclear basically only has a very limited amount of fake arguments constantly used in variations of the same chain:
“Nuclear is perfectly safe!”
“That’s not the problem. The problems are the massive costs and the waste.”
“But we can recycle most of the waste. Also renewables produce so much waste, too.”
“But you actually don’t do it because it’s very expensive and makes nuclear power even less economicallly viable. Also how is recycling wind-turbine blades and solar-panels unrealistic but recycling nuclear waste is not?”
“But nuclear would be economically viable and so much cheaper if it wasn’t so over-regulated. And lithium mining is so toxic to the environment.”
“It’s only perfectly safe because it’s highly regulated. And we don’t actually need lithium for grid storage where energy optimised density is not the biggest concern.”
“<Inserts insults about you being brain-washed to fear nuclear power here>, also nuclear will totally become much cheaper with SMRs any day now…”
In the end it’s always the same story. Nuclear might be safe but it is insanely expensive and produces radioactive waste. No, the fact that you can theoretically recycle the waste doesn’t matter, because you don’t do it. No, it will not become cheap magically soon. And no it is not expensive because it’s highly regulated because without those regulations we can start at the top again and talk about how safe it is.
There are only two reasons to pretend otherwise: you work in nuclear power and need to sell your product or you work in fossil fuels and need to keep the discussion up so people keep talking instead of actually working to get rid of them. And the nuclear industry and lobby is actually not that massive compared to the fossil fuel one. So it’s very clear where the vast majority of nuclear fan boys get their talking points. Have you ever thought about the fact why pro-nuclear is so massively over-represented on social media? 😉
PS: Nice, I only need to scroll ~ one page up and down to find all those fake arguments repeated here. How surprising /s
Capturing all the extra carbon from the atmosphere is not as expensive as it sounds like. It can easily be done by a few rich countries in very few decades once we stop adding more there every day.
Recycling nuclear waste is one of those problems that should be easy but nobody knows what the easy way looks like. It’s impossible to tell if some breakthrough will make it viable tomorrow or if people will have to work for 200 years to get to it. But yeah, currently it’s best described as “impossible”.
Capturing all the extra carbon from the atmosphere is not as expensive as it sounds like. It can easily be done by a few rich countries in very few decades once we stop adding more there every day.
What?
For starters, carbon capture takes an insane amount of power. And to follow up: we couldn’t even build the facilities is “a few decades” even if we free power and infinite money.
If something is Nuclear enough it can generate heat, its just the reactors make use of an actual reaction that nuclear waste can’t do anymore. Yever watch the Martian, he has a generator that’s fuel is lead covered beads of radioactive material, it doesn’t generate as much as reactors but it’s still a usable amount.
If something is Nuclear enough it can generate heat
That’s an extreme oversimplification. RTGs don’t use nuclear waste. Spent reactor fuel still emits a large amount of gamma and neutron radiation, but not with enough intensity to be useful in a reactor. The amount of shielding required makes any kind of non-terrestrial application impossible.
The most common RTG fuel is plutonium (238Pu, usually as PuO2), which emits mostly alpha and beta particles, and can be used with minimal shielding. It can’t be produced by reprocessing spent reactor fuel. In 2024, only Russia is manufacturing it. Polonium (210Po) is also an excellent fuel with a very high energy density, but it has a prohibitively short half-life of just over a hundred days. It also has to be manufactured and can’t be extracted.
90Sr (strontium) can be extracted from nuclear fuel, and was used by early Soviet RTGs, but only terrestrially because the gamma emission requires heavy shielding. Strontium is also a very reactive alkaline metal. It isn’t used as RTG fuel today.
But it’s not done well. Just look at the new built plants, which are way over budget and take way longer to build then expected. Like the two units in Georgia that went from estimated 14bn to finally 34bn $. In France who are really experienced with nuclear, they began building their latest plant in 2007 and it’s still not operational, also it went from 3.3bn to 13.2bn €. Or look at the way Hinkley Point C in the UK is getting developed. What a shit show: from estimated 18bn£ to now 47bn£ and a day where it starts producing energy not in sight.
That’s for the nuclear industry to figure out. But the fact that companies from different companies originating in entirely different countries suggest that it’s a problem with the tech itself.
The hard truth many just don’t want to admit is that there are some technologies that simply aren’t practical, regardless of how objectively cool they might be. The truth is that the nuclear industry just has a very poor track record with being financially viable. It’s only ever really been scaled through massive state-run enterprises that can operate unprofitably. Before solar and wind really took off, the case could be made that we should switch to fission, even if it is more expensive, due to climate concerns. But now that solar + batteries are massively cheaper than nuclear? It’s ridiculous to spend state money building these giant white elephants when we could just slap up some more solar panels instead. We ain’t running out of space to put them any time soon.
Sometimes it’s documented but often I’d say it’s a selling technique that works for any big infrastructure project. You give a rather low first cost projection, governments decide let’s do this and after a while you correct the price up. First, people say: well that is to be expected the project shouldn’t fail because of a little price hike. Then the price gets corrected again and then the sunken cost fallacy kicks in. now we are to deep in and we have to pull through. And so on. And you probably can’t get price guarantees for such big projects cause no one would make a bid. It’s a very flawed system. I’d like to know how often solar or windpark projects get price adjusted?
The same problems faced the oil industry too, with their drilling rigs & refineries (over budget and over schedule, with gov money grants and subsidies), it’s just less in the media & more spread out (more projects).
Also 10s of billions is still insignificant for any power, transport, or healthcare infrastructure in the scheme of things - we have the money, we just don’t tax profit enough. And we don’t talk about how the whole budget gets spent (private or public), where all the money actually goes, instead we get the highlighted cases everyone talks about. But not about the shielded industries when they fuck up.
Also 10s of billions is still insignificant for any power, transport, or healthcare infrastructure in the scheme of things -
Bullshit. If you can get the same amount of reliable power by just slapping up some solar panels, wind turbines, and batteries, then obviously the cost is not insignificant.
That sentence shows that you really aren’t thinking about this as a practical means of power generation. I’ve found that most fission boosters don’t so much like actual nuclear power, but the idea of nuclear power. It appeals to a certain kind of nerd who admires it from a physics and engineering perspective. And while it is cool technically, this tends to blind people to the actual cold realities of fission power.
There’s also a lot of conspiratorial thinking among the pro-nuclear crowd. They’ll blame nuclear’s failures on the superstitious fear of the unwashed ignorant masses or the evil machinations of groups like Greenpeace. Then, at the same time, they’ll ignore the most bone-headedly obvious cause of nuclear’s failure: it’s just too fucking expensive.
Bullshit. If you can get the same amount of reliable power by just slapping up some solar panels, wind turbines, and batteries, then obviously the cost is not insignificant.
I’m thinking in practical terms how that still doesn’t happen that often, humans allocate assets, humans don’t behave logically (behavioural economics).
Nothing ever is going to be perfect and efficient, solar panels might get through vast price volatilities as well, installation costs hand already soared.
Then, at the same time, they’ll ignore the most bone-headedly obvious cause of nuclear’s failure: it’s just too fucking expensive.
So why did we subsidised so much expensive oil infrastructure. And at higher cost of life.
Oil rigs can go into billions of dollars (and thats not even the total cost), nuclear plants tend to have the total running cost up-front (with decommission costs after the planned decades).
Well if we had no alternative I would agree with you and I would be okay if we had to subsidize nuclear (which isn’t emissions free due to the mining and refining of uranium bye the way). But if a country like France, which has a pretty high rate of acceptance regarding nuclear, can’t get it to work, who will? Apart from maybe authoritarian countries. Just think about the amount of plants we have to build to create a significant impact, if hardly any plant has been built in a relative short timeframe. I’d say put money in research yeah but focus on renewable, network, storage and efficiency optimization for now.
only antimatter could provide more energy density, it’s insanely powerful.
Nuclear energy indeed has very high energy per mass of fuel. But so what? Solar and wind power doesn’t even use fuel. So the energy density thing is a bit of a distraction.
What are you trying to say here? Are we still talking about fuel types here?
Again, let me point out that solar power does not consume any fuel. The materials used to construct the solar panels are not having any power extracted from them. And secondly, nuclear power plants require construction materials too. … So I really don’t know what kind of comparison you are asking for here.
yes it does, but indirectly : making solar panels comes with the cost of dumping them after they’ve been used, because they’re not fully recyclable. (which comes after 15/20 years if not earlier). plus they use vast amounts of land when much power is needed.
so yeah, energy density is relevant when comparing technologies. otherwise, why aren’t we all cycling to power our toasters / ovens / refrigerators ? because the energy yield is bad.
so no, you shouldn’t dismiss nuclear, because it’s insanity powerful for its cost.
solar and wind are great, but insufficient on their own.
The cost of constructing and decommissioning power plants is important for sure; but it has nothing to do with energy density - which is what we were talking about before. It’s true that building solar panels takes energy and resources, and the panels don’t last indefinitely. So there is a lifecycle cost to using them. But the same is true for all forms of power generation.
A common way to compare these costs is to look at the ‘payback time’ of each form of power generation. The payback time is the amount of time it would take for the power plant to produce enough energy to pay back the lifecycle costs required to build, operate, and decommission that type of plant. It’s basically how long it takes for the construction to have been ‘worth it’.
In terms of payback time, wind power is by far the best; typically taking less than 1 year to pay itself off. Solar is pretty good too, but is highly dependent on where it is used. And nuclear… is not good on this measure. It takes decades for a nuclear power plant to pay itself off, because the plants are very expensive to build and decommission.
Obviously there are other things to consider in terms of the strengths and weaknesses of different forms of power generation. But you’ve been talking about the cost of materials and construction as though it is a weakness of renewables, and it really really isn’t. That’s in fact one of their strengths, and a major weakness of nuclear. Its strange that you say nuclear is ‘insanity powerful for its cost’, because its cost is the greatest weakness of nuclear power. Its much cleaner than coal, but much more expensive, even though it uses so little fuel. And it is not cleaner than solar or wind, but it is still more expensive.
Your point about land usage is a stronger point in favour of nuclear power… except that depending on what country you are talking about, that could easily swing the other way. Solar and wind do take up more space than nuclear, that’s for sure. But nuclear requires certain geological conditions for the safe operation of the plant, and the storage of waste. So depending on where you live, finding unused land suitable for renewables can be much easier than finding a suitable location for a nuclear power plant and waste containment facility.
Who cares? We use economics to sort out the relative value of radically different power sources, not cherry-picked criteria. Fission boosters can say that nuclear has a small footprint. Solar boosters can say that solar has no moving parts and is thus more mechanically reliable. Fission boosters can say fission gets more power from the same mass. Solar boosters can point to the mass of the entire fission plant, including the giant concrete dome that needs to be strong enough to survive a jumbo jet flying into it.
In the end, none of this shit matters. We have a way of sorting out these complex multi-variable problems. Both fission and solar have their own relatives strengths and weaknesses that their proponents can cherry pick. But ultimately, all that matters in choosing what to deploy is cost.
And today, in the real world, in the year 2024, if you want to get low-carbon power on the grid, the most cost-effective way, by far, is solar. And you can add batteries as needed for intermittency, and you’re still way ahead of nuclear cost-wise. And as our use of solar continues to climb, we can deploy seasonal storage, which we have many, many options to deploy.
The ultimate problem fission has is that it just can’t survive in a capitalist economy. It can survive in planned economies like the Soviet Union or modern China, or it can run as a state-backed enterprise like modern Russia. But it simply isn’t cost effective enough for fission companies to be able to survive on their own in a capitalist economy.
And frankly, if we’re going to have the government subsidize things, I would much rather the money be spent on healthcare, housing, or education. A lot of fission boosters like fission simply because they think the tech is cool, not necessarily because it actually makes economic sense. I say that if fission boosters want to fund their hobby and subsidize fission plants, let them. But otherwise I am adamantly opposed to any form of subsidies for the fission industry.
Energy density is a useless bullshit metric for stationary power.
Produces more waste than almost all of the renewables.
Reliable compared to… … … ok, I’m out of ideas, they need shutdowns all the time. Seems to me it’s less reliable than anything that isn’t considered “experimental”.
And it can’t work with renewables unless you add lots and lots of batteries. Any amount of renewables you build just makes nuclear more expensive.
They are an interesting technology, and I’m sure they have more uses than making nuclear weapons. It’s just that everybody focus on that one use, and whatever other uses they have, mainstream grid-electricity generation is not it.
Who gives a fuck about energy density beyond some physics nerds? Unless you’re planning on building a flying nuclear-powered airplane, energy density is irrelevant. This is why solar is eating fission’s lunch.
only antimatter could provide more energy density, it’s insanely powerful.
produces amounts of waste orders of magnitude lower than any other means of energy production
reliable when done well
it shouldn’t be replaced with renewables, but work with them
Yes, but energy density doesn’t matter for most applications and the waste it produces is highly problematic.
