Even if you discard everything else, this section seems particularly relevant:
The long lead times for construction that invalidate nuclear power as a way of mitigating climate change was a point recognized in 2009 by the body whose mission is to promote the use of nuclear power, the International Atomic Energy Agency (IAEA). “Nuclear power is not a near-term solution to the challenge of climate change,” writes Sharon Squassoni in the IAEA bulletin. “The need to immediately and dramatically reduce carbon emissions calls for approaches that can be implemented more quickly than building nuclear reactors.”
Wealer from Berlin’s Technical University, along with numerous other energy experts, sees takes a different view.
“The contribution of nuclear energy is viewed too optimistically,” he said. “In reality, [power plant] construction times are too long and the costs too high to have a noticeable effect on climate change. It takes too long for nuclear energy to become available.”
Mycle Schneider, author of the World Nuclear Industry Status Report, agrees.
“Nuclear power plants are about four times as expensive as wind or solar, and take five times as long to build,” he said. “When you factor it all in, you’re looking at 15-to-20 years of lead time for a new nuclear plant.”
He pointed out that the world needed to get greenhouse gases under control within a decade. “And in the next 10 years, nuclear power won’t be able to make a significant contribution,” added Schneider.
Long lead times against nuclear have bee raised for the last 25 years, if we had just got on with it we would have the capacity by now. Just cause the lead time is in years doesn’t mean it isn’t worth doing.
As others pointed out, to build that many nuclear power plants that quickly would require 10x-ing the world’s construction capacity.
My counterpoint is that if we had “just got on with it” for solar, wind, and battery, we would have the capacity by now and the cost per kwh of that capacity would be approximately half as much as the same in nuclear. And we would have amortized the costs.
No it wouldn’t. China laid more concrete in 5 years than the entire world did in 100 years. I highly doubt that converting the entire world to nuclear is going to use that much more concrete. I mean hell, they laid like 15 or 20,000 miles of high speed rail in just a few years. They built like 300 million apartment units.
Just did a bunch of my own math before realizing those numbers were already out there. We would need to add 3960 nuclear plants to match current energy demand for the world (440 power 10% of the world).
That would require at least 5 years of construction per plant. It takes about 7000 workers to produce a nuclear plant. To produce them concurrently would require about 27.7 million construction workers dedicated to this project for at least 5 years. So on one hand, perhaps you’re right, since there are 100M construction workers in the world. I can’t, however, find numbers about how much heavy equipment exists to facilitate a product requiring 1/4 the world’s construction workers concurrently. You might be right that if all other construction were ground to a halt, we might be able to manage a 5-year plan of nuclear at the cost of about $20T (I had done the math before realizing this reply were about workers, not cost stupidity). I concede it seems “10x increase world construction capacity” was wrong, and the real number is somewhere around 1.5-2x, so long as we stay conservative with nuclear figures and ignore extra costs of building or transporting nuclear energy to countries incapable of building their own plants.
Interestingly, at those construction numbers, you could provide small-project rooftop solar to the world. I can’t find construction numbers for power farm solar, except that it’s dramatically more efficient than rooftop solar. Unlike nuclear, it appears we could easily squeeze full-world solar with our current world construction capacity.
I won’t bore you with the cost math, but since I calculated them I’m still going to summarize them. Going full nuclear would cost us about a $20T down payment. Going full solar (with storage) down payment is about $4T (only about $1T without storage costs factored). And while nuclear would be cheaper than solar per year after that $20T down, solar power and storage would STILL be cheaper in a 100 year outlook, but would also benefit from rolling efficiency increases as we add new solar plants/capacitors and tear down older ones…
Not all 7,000 construction workers would be working on the site concurrently. Different trades come and go depending on the phase of the project. So at first you’ll have the civil engineering earth movers come in, who clears the site and excavates the foundations. Then you’ll have the concrete crews come in who pour the foundations and do all of the concrete work. Obviously on a nuclear power plant there is a lot of foundation work, as well as a lot of above ground concrete so probably a good chunk of the construction workers will fall into this category.
Power plants also have a lot of structural steel work, electrical and special equipment that would likey fall under the piping category but each of these uses a separate set of skilled labor that does not overlap.
If you were going to actually try to build 3,300 nuclear power plants, you would rotate crews from project to project which would increase efficiency rather than hiring 27 million separate workers.
In any case, I don’t think converting the world’s total electrical power generation to 100% nuclear is by any stretch of the imagination a good idea. Personally I think maybe 15 to 25% nuclear power generation would be a more realistic mix, similar to the US electrical power generation. The rest of the power should be solar, wind, hydro, wave and geothermal as they are absolutely cheaper to build.
I’m not sure I agree with how you’d be able to execute on that level or organized construction safely, but I think we’re also reaching the “impossible-to-be-sure hypothetical” territory, so I’ll concede the point for now.
I think my problems of cost and time still stand. It looks like adding rooftop solar with batteries to every building is still cheaper (on startup, and likely per MW) than nuclear plants. Regions that cannot support solar, onland wind, geo, or hydro can justify nuclear (at least unless shipping batteries or hydrogen conversion becomes cheap enough to compete), but I don’t think they amount to nearly 15% of the power needs in the world since they represent fairly distinctive regions with low energy demand.
We do it all the time in the construction industry.
For instance, Bechtel has 55,000 people in the US.
“Since the 1950s, Bechtel has designed, serviced, or delivered 80% of all nuclear plants in the U.S… Bechtel has provided engineering and construction services for 88 of the 104 operating nuclear plants in the United States.”
So just hire them. Too bad they lost almost all of their institutional knowledge about nuclear construction compared to what they used to have.
Long lead times, cost overruns, producing power at a higher price point than renewables, long run time needed to break even, even longer dismantling times and a still unsolved waste problem. Compared to renewables that we can build right now.
Did you read the quote? 15-20 years, as in decades before 1 nuke plant is built. I agree in that politicians of the past should have led us to a more sustainable and resilient energy future, but we’re here now.
Advanced nuclear should still be 100% pursued to try to get those lead times down and to incorporate things like waste recycling, modularity, etc., but the lead time in decades absolutely means nuclear power might not be something worth doing.
The IPCC puts the next 10-20 years as the most important and perilous for getting a hold on climate change. If we wait for that long by not rolling out emission-free power sources, transit modes, or even carbon-free concrete, etc., then we might cross planetary boundaries that we can’t come back from.
Nuclear is a safe bet and bet worth pursuing. I would argue that, along with that source from the IAEA, old nuclear is note worth it.
How much concrete does it take to build a nuclear plant? Concrete production is currently 8% of global emissions, so if you have to scale up construction capacity 10x for the next decade, don’t you end up destroying the environment with concrete before they are even operational?
Great point. You need concrete for wind, solar, and li-ion battery storage too (including pumped hydro), but out of those I’d say pumped hydro is the only one that remotely compares in the amount of concrete needed for construction.
So purely looking at the emissions from materials needed to build these power sources, renewables have the edge due to less concrete. These emissions might show up elsewhere in raw material extraction like with silicon for solar, and then the rare earth metals needed for generators in wind, all the lithium/nickel/cobalt needed for batteries, etc., but I want to say that the Life Cycle Assessments (LCAs) from places like the National Renewable Energy Laboratory (NREL) in the US or the International Energy Agency (IEA) worldwide have taken that into account and still show that renewables + storage are cheaper on a carbon basis compared to fossil fuels and nuclear.
The cool thing about concrete for renewables (excluding hydro dam) is only the very base pad needs to be virgin. You can make a lot of the rest of the base and fill material with down cycled concrete. So tearing down part of an old factory on land near the solar panels are? Crush it up and only move it a few miles over to where you need it. Rather than hauling that to a landfill where it sits forever, costing energy use to haul, and more energy use to bring the fill and other bade materials from a further destination.
Sorry. How does wind power kill anyone? Okay, every once in a while you hear about a technician falling off a windmill, but are there any fatalities in regard to the effects of wind power?
“in 2011 coal produced about 180 billion kWhrs in England with about 3,000 related deaths. Nuclear energy produced over 90 billion kWhrs in England with no deaths. In that same year, America produced about 800 billion kWhrs from nuclear with no deaths.”
The only two major nuclear-related death incidents were Chernobyl and Fukushima. But Fukushima only killed one person, the rest were killed by the tsunami and being relocated from the exclusion zone. But many people blame the Japanese government for fucking up the evacuations, while other people criticize the government for actually evacuating people.
In any case, those 2,300 Japanese people were not killed by the actual nuclear incident, they were killed because they were very old and could not adapt to moving into a new apartment that’s a government provided them. Chernobyl is believed to have killed about 500 people.
I should also mention that the Fukushima exclusion zone has largely been lifted, and many people have moved back home.
Lacking safety standards specific to the use case of wind turbines. For example, there was a fire during installation and someone jumped to their deaths to get away. They had quick decent harnesses but couldn’t use them because of the location of the fire.
And? Those safety standards for constructing and maintaining wind turbines can be increased just as much as the safety standards for any other type of heavy labor. For example by mandating that wind turbines must have fire suppression systems installed or that wworkers must be able to rapel on the outside of the wind turbine.
Those aren’t arguments against nuclear power; those are arguments against the incompetence of entities like Southern Company and Westinghouse, as well as the Public Service Commission that fails to impose the burden of cost overruns on the shareholders where they belong.
I should know; I’m a Georgia Power ratepayer who’s on the hook paying for the fuck-ups and cost overruns of Plant Vogtle 3 and 4.
It would’ve been way better if they’d been built back in the '70s, since all indications are that the folks who built units 1 and 2 actually had a fucking clue what they were doing!
“We should just go nuclear, renewables aren’t viable” is just the next step in the ever-retreating arguments of climate change denial. First climate change wasn’t real. Then it was real but not man-made. One of the popular tactics today is to push nuclear, because they know how effective it can be at winning over progressives to help with their delaying tactics.
So… climate change deniers want to delay action on climate change. So they push for nuclear because it has long lead times and that forestalls action?
Come on man. That’s a pretty ridiculous theory. Climate change deniers are out there yelling “drill baby drill” not going undercover as nuclear advocates.
He’s completely right, and I don’t get why more people don’t see that. As an example, here in Denmark, the leader of the far right populist party is both the one saying climate change would be a good thing since it means warmer summer weather as well as constantly bringing up nuclear energy any single time someone starts talking about climate change. It’s honestly so transparent. I used to see the same thing all the time on Reddit, and now I guess it’s Lemmy’s turn for this shit.
because it has long lead times and that forestalls action
I won’t profess to know for sure what their reasoning is. I suspect it’s a bit of that, and also a bit of hope/expectation that the fossil fuel industry will be well-situated to pivot into nuclear in a way that they can’t as easily do with renewables. The more centralised nature and heavy reliance on large-scale resource extraction is very similar. But they actual explanation isn’t what’s important.
What’s important is the simple fact that the biggest climate change deniers are now trying to promote nuclear. If you want to refute the claim, you need to explain that better than I can.
I’m not very familiar with Australian politics or leaders so I can only go with what I see in those articles. First, I don’t see any climate change denial. I see a debate about renewables and nuclear
Why are conservatives against renewables:
They can’t meet our total energy needs.
Wind and solar products are predominantly made in China and conservatives don’t want to feed the Chinese economy or increase dependence (one thing I do know about AU is that Chinese influence is quite heavy and a cause of great concern there).
Why are conservatives pro-nuclear:
It provides baseload capacity that supports wind/solar where they are weak.
It has military applications.
It creates large infrastructure spending within AU and supports mining industry.
They believe it will rankle liberals.
Maybe you have a point that conservatives who are dead-set against renewables will throw nuclear into the conversation as a distraction which they know will not go anywhere. But as an outside observer who doesn’t have built up associations with these characters, I honestly just see rational inclusion of nuclear in the energy mix. This all seems healthy to me.
That is factually false information. There are solid arguments to be made against nuclear energy.

Surely the second best time would have been 29 years ago

the largest fission plant was literally working 5 years after construction started
fission plants are just more expensive now because we don’t make enough of them.
I guess safety standards changed but even wind power kills more people per watt than fission so ¯\_(ツ)_/¯
Nuclear could’ve easily worked if people didn’t go full nimby in the past few decades
Sorry. How does wind power kill anyone? Okay, every once in a while you hear about a technician falling off a windmill, but are there any fatalities in regard to the effects of wind power?
Fewer people die to nuclear than wind power.
Nuclear is scary because you hear about it, not because it is actually deadly.
To be fair, Frank falling to his death from the top of wind turbine 45 has much shorter consequences.
It won’t have distant descendants dying after not working out symbols meant to not play with the glowing stuff left by the ancients.
Like tragic Glowing Peril tale: https://timharford.com/2023/11/cautionary-tales-the-lethal-fallout-of-a-stolen-treasure/
probably technicians falling off is the biggest thing

So it isn’t wind at all, but lacking safety standards.

Okay, so increase those safety standards on wind then get back to us with price per kilowatt and project lead times.
