So uh, turns out the energy companies are not exactly the most moral and rule abiding entities, and they love to pay off politicians and cut corners. How does one prevent that, as in the case of fission it has rather dire consequences?
Big news worthy accidents are a really good way to ensure strong regulation and oversight. And nuclear is very regulated now so that it has lower death rate than wind power.
Since you can apply that logic to everything, how can you ever build anything? Because all consequences are dire on a myopic scale, that is, if your partner dies because a single electrician cheaped out with the wiring in your building and got someone to sign off, “It’s not as bad as a nuclear disaster” isn’t exactly going to console them much.
At some point, you need to accept that making something illegal and trying to prosecute people has to be enough. For most situations. It’s not perfect. Sure. But nothing ever is. And no solution to energy is ever going to be perfect, either.
Exactly, just like a windmill running and a nuclear power plant running have very different effects on the power grid. Hence why comparing them directly is often such a nonsense act.
That’s why there are lots of regulations for things impacting life safety. With a nuclear power plant, you mitigate the disaster potential by having so many more people involved in the design and inspection processes.
The risk of an electrician installing faulty wiring in your home could be mitigated by having a third party inspector review the work. Now do that 1000x over and your risk of “politicians are paid off” is negligible.
Regulations are actually generally created by regulatory bodies, which are usually non-political. For instance, the underwriter laboratory is the major appliance, building and electrical approval body in the United States.
In most countries, building codes and safety codes are created by industry specialists, people who have been in the industry as professionals for many decades and have practiced and been licensed in the field that they are riding the regulations for.
There’s a big difference between politicians who are passing these laws, and those writing them who are the regulatory bodies. Generally, as a politicians will simply adopt the codes as recommended by the professional licensing and certification bodies.
I suppose it will be the end of modern civilization if politicians decide to politicize electrical or building codes. Then we’ll be fucked for sure. We’ve seen that happen before with the Indiana pi bill.
“The Indiana Pi Bill is the popular name for bill #246 of the 1897 sitting of the Indiana General Assembly, one of the most notorious attempts to establish mathematical truth by legislative fiat.”
That’s why there are lots of regulations for things impacting life safety
Regulations that a lot of pro-nuclear people try to get relaxed because they “artificially inflate the price to more than solar so that we’ll use solar”. I’m not saying all pro-nuclear folks are tin-foilers, but the only argument that puts nuclear cheaper than solar+battery anymore is an argument that uses deregulated facilities.
If solar+wind+battery is cheaper per MWH, faster to build, with less front-loaded costs, then it’s a no-brainer. It only stops being a no-brainer when you stop regulating the nuclear plant. Therein lies the paradox of the argument.
Because the energy industry is historically the one lobbying governments for less regulation. Also, has there ever been a nuclear project in the history of mankind that didnt result in depleted Uranium leeching into local watertables and/or radioactive fallout? Your comment is basically tacit acceptance that people are going to act unethically, which, in regards to nuclear power, is bound to have human consequences.
Easy. Have nuclear power plants operate as government run and backed corporations (what we’d call a “Crown Corporation” here in Canada).
That way you can mandate safety and uptime as metrics over profit. It may be less efficient from an economic standpoint (overall cost might be higher), but you also don’t wind up with the nuclear version of Love Canal.
Or they could just allow everyone to build nuclear reactors in their backyard, everyone is saying that they are safer than a banana so i don’t see any issue
I mean it’s not the companies operating the facilities we put our trust in, but the outside regulators whose job it is to ensure these facilities are safe and meet a certain standard. As well as the engineers and scientists that design these systems.
Nuclear power isn’t 100% safe or risk-free, but it’s hella effective and leaps and bounds better than fossil fuels. We can embrace nuclear, renewables and fossil free methods, or just continue burning the world.
Don’t push nuclear power like it’s the only option though.
Where I live we entirely provide energy from hydro power plants and nuclear energy is banned. We use no fossil fuels. We have a 35 year plan for future growth and it doesn’t include any fossil fuels. Nuclear power is just one of the options and it has many hurdles to implement, maintain and decommission.
Honestly, if you can, hydro is brilliant. Not many places can though — both because of geography and politics. Nuclear is better than a lot of the alternatives and shouldn’t be discounted.
I know it’s a damn lot easier than carbon recapture, if we’re talking waste products. It’s not ideal, but there is no such thing as perfect, and we shouldn’t let that be the enemy of good. Nuclear fission power is part of a large group of methods to help us switch off fossil fuels.
“Easier”? Are you aware of the fact that radioactive waste tombs are meant to stand for millions of years? It requres a lot of territory, construction and servance charges, and lots of prays for nothing destructive happens with it in its “infinite” lifetime.
The problem is its potential for harm. And I don’t mean meltdown. Storage is the problem that doesn’t seem to have strong solutions right now. And the potential for them to make a mistake and store the waste improperly is pretty catastrophic.
“Nuclear waste” sounds super scary, but most of it are things like tools and clothing, that have comparatively tiny amount of radioactivity. Sure it still needs to be stored properly, very little high level waste is actually generated.
You know what else is catastrophic? Fossil fuels and the impact they have on the climate. I’m not arguing that we should put all our eggs in one basket, but getting started and doing something to move away from the BS that is coal, gas, and oil is really something we should’ve prioritised fifty years ago. Instead they have us arguing whether we should go with hydroelectric, or put up with “ugly windmills” or “solar farms” or “dangerous nuclear plants.”
It’s all bullshit. Our world is literally on fire and no one seems to actually give a fuck. We have fantastic tools that could’ve halted the progress had we used them in time, but fifty years later we’re still arguing about this.
At this point I honestly hope we do burn. This is a filter mankind does not deserve to pass. We’re too evil to survive.
Yea both are horrible. But we can get off fossil fuels and walk away. We can’t with nuclear. It’ll always be with us and doesn’t solve that we need fossil fuel for other things.
Jets and ships are still going to need fossil fuels.
Which is why I think the best thing we could be doing right now is focusing on improving how energy is store. With the right advancement we could solve a lot of these problems with the right battery.
Mercury will always be with us. Arsenic will always be with us. PFAS will always be with us. Natural radiation will always be with us. Fortunately, nuclear waste is easily detectable, the regulations around it are much stronger, the amount of HLW is miniscule and the storage processes are incredibly advanced
Moreover, most Nuclear waste won’t always be with us. A lot of fission prodcuts have half lives in the decades or centuries
Except that powering the world with nuclear would require thousands of reactors and so much more disasters. This doesn’t even factor the space abandonned to store «normal» toxic materials.
By not picking, you are picking fossil fuels. Because we can’t fully replace everything with solar/wind yet, and fossil fuels are already being burned as we speak.
No, give me an option that doesn’t make a part of the world uninhabitable or increases climate change.
That just a stupid comparison and is there any reason why we can’t also do wind solar thermal hydro also? It’s fossil fuels or nuclear and that’s it huh?
Bet you’d feel* differently if you were a resident of one of the island nations that’s going to drown in the next decade or two. That part of the world’s definitely going to be uninhabitable if we continue to do nothing.
How do you get the uranium or thorium? Generally, it has to be mined. Are we using nuclear powered mining equipment? No. We use fossil fuel powered mining equipment. Then we use fossil fuels to power the trucks that take the depleted nuclear product to the storage depot, which is powered and requires employees who drive there using fossil fuel powered vehicles, using fossil fuel powered warehouse equipment. When does nuclear power phase out the fossil fuel power? Are we going to decommission oil and coal production facilities? Or are we just going to use nuclear to augment the grid?
Don’t forget all the fossil fuels used in machinery that builds nuclear power plants, and the CO2 emissions from all of the concrete used.
Oh, and if you start building a nuclear power plant right now it will be online (maybe) in a decade or two and hopefully for only 150% of the initial cost. There’s a nuclear power plant in Georgia that is $17 BILLION over budget.
And we would be expecting these corrupt Cost cutting types to warehouse nuclear waste for hundreds if not thousands of years while requiring regular inspections and rotation of caskets periodically while also maintaining the facilities. All of that for a product that doesn’t produce any value, it just sits there and accumulates.
And where does it get stored? Right now almost 100% of waste is stored on site above ground because they really have no good solution. People will say things like “its just a little bit of toxic waste” or “its cool because we could use it in process we don’t have yet but might in the future” and all I can think of is how this was the same thinking that got us into our dependence on our first environmental catastrophic energy source. I’m not confident we that scaling up to another one will end well.
Right now almost 100% of waste is stored on site above ground because they really have no good solution.
You mean there’s so little they don’t even need a dedicated facility for it, and it’s safe enough that people are willing to work where it’s stored? Sounds great!
One reason it wasn’t made a priority 50 years ago is because Jimmy Carter - a nuclear submariner who understood the risks and economics - decided it wasn’t a good idea.
This is a man who was present at a minor nuclear accident, who helped create the modern nuclear submarine fleet, acknowledging that nukes weren’t going to help during the height of the Oil Embargo.
Anti-nuclear is like anti-GMO and anti-vax: pure ignorance, and fear of that which they don’t understand.
First of all anti- #GMO stances are often derived from anti-Bayer-Monsanto stances. There is no transparency about whether Monsanto is in the supply chain of any given thing you buy, so boycotting GMO is as accurate as ethical consumers can get to boycotting Monsanto. It would either require pure ignorance or distaste for humanity to support that company with its pernicious history and intent to eventually take control over the world’s food supply.
Then there’s the anti-GMO-tech camp (which is what you had in mind). You have people who are anti-all-GMO and those who are anti-risky-GMO. It’s pure technological ignorance to regard all GMO equally safe or equally unsafe. GMO is an umbrella of many techniques. Some of those techniques are as low risk as cross-breeding in ways that can happens in nature. Other invasive techniques are extremely risky & experimental. You’re wiser if you separate the different GMO techniques and accept the low risk ones while condemning the foolishly risky approaches at the hands of a profit-driven corporation taking every shortcut they can get away with.
So in short:
Boycott all U.S.-sourced GMO if you’re an ethical consumer. (note the EU produces GMO without Monsanto)
Boycott just high-risk GMO techniques if you’re unethical but at least wise about the risks. (note this is somewhat impractical because you don’t have the transparency of knowing what technique was used)
Boycott no GMO at all if you’re ignorant about risks & simultaneously unethical.
The daft thing is that even if another Chernobyl happened (unlikely given superior technology and safety standards) it wouldn’t be anywhere near as damaging as climate change.
The radiation would only affect a small area of the planet not the whole world, and technically radiation doesn’t even cause climate damage. Chernobyl has plenty of trees and plenty of wildlife, it’s just unsuitable for human habitation.
The daft thing is that even if another Chernobyl happened (unlikely given superior technology and safety standards) it wouldn’t be anywhere near as damaging as climate change.
Here’s my favorite way to put it: because of trace radioactive elements found in coal ore, coal-fired power plants produce more radioactivity in normal operation than nuclear power plants have in their entire history, including meltdowns. And with coal, it just gets released straight into the environment without any attempt to contain it!
And that’s just radioactivity, not all the other emissions of coal plants.
This is a fun fact but I don’t think it matters, no one is getting radiation sickness from coal smoke. Don’t misunderstand me, I’m not saying coal smoke is healthy, it’s fucking awful and causes way more deaths than nuclear power plants.
Federation of American scientists (FAS) believe that the number is actually calculable:
“The quantity of radioactive material liberated by the burn-
ing of coal is considerable, since on average it contains a few parts per million
of uranium and thorium”
“Per gigawatt-
year (GWe-yr) of electrical energy produced by coal, using the current mix of
technology throughout the world, the population exposure is estimated to be
about 0.8 lethal cancers per plant-year distributed over the affected population.”
“Table 7.2 summarizes these data. With 400 GWe of coal-fired power plants in the world, this amounts to some 320 deaths per year; in the world at large, some plants have better filters and cause less harm, while others have little stack-gas cleanup and cause far more.”
I totally agree that current nuclear power generation should be left running until we have enough green energy to pick up the slack, because it does provide clean and safe energy. However, I totally disagree on the scalability, for two main reasons:
Current nuclear power generation is non-renewable. It is somewhat unclear how much Uranium is available worldwide (for strategic reasons), but even at current production, supply issues have been known to happen. And it goes without saying that waiting to scale up some novel unproven or inexistent sustainable way of nuclear power production is out of the question, for time and safety reasons. Which brings me to point 2.
We need clean, sustainable energy right now if we want to have any chance of fighting climate change. From start of planning of a new nuclear power plant to first power generation can take 15 or 20 years easily. Currently, about 10% of all electricity worldwide is produced by about 400 nuclear reactors, while around 15 new ones are under construction. So, to make any sort of reasonable impact, we would have to build to the tune of 2000 new reactors, pronto. To do that within 30 years, we’d have to increase our construction capacity 5 to 10 fold. Even if that were possible, which I strongly doubt, I would wager the safety and cost impacts would be totally unjustifiable. And we don’t even have 30 years anymore. That is to say nothing of regulatory checks and maintenance that would also have to be increased 5 fold.
So imho nuclear power as a solution to climate change is a non-starter, simply due to logistical and scaling reasons. And that is before we even talk about the very real dangers of nuclear power generation, which are of course not operational, but due to things like proliferation, terrorist attacks, war, and other unforseen disruptions through e.g. climate change, societal or governmental shifts, etc.
It is somewhat unclear how much Uranium is available worldwide (for strategic reasons), but even at current production, supply issues have been known to happen.
Nuclear fission using Uranium is not sustainable. If we expand current nuclear technologies to tackle climate change then we’d likely run out of Uranium by 2100. Nuclear fusion using Thorium might be sustainable, but it’s not yet a proven, scalable technology. And all of this is ignoring the long lead times, high costs, regulatory hurdles and nuclear weapon proliferation concerns that nuclear typically presents. It’d be great if nuclear was the magic bullet for climate change, but it just ain’t.
We’d run of our uranium that’s economical to extract using current technology and at current prices. All known mineral reserves could power the world on exclusively nuclear energy for several thousand years at least.
All known mineral reserves could power the world on exclusively nuclear energy for several thousand years at least.
You got a source for that? Because the one I linked says that we run out of known Uranium deposits by 2100 at current usage rates. Our known Uranium deposits run out mid-century if we use nuclear to follow the IEA Blue Map plan to reduce carbon emissions by 50%, and we run out of even speculated deposits by 2100 under that scenario. Where are you getting “several thousand years” from? Is Thorium part of the mineral reserves to which you’re referring?
The source you linked talks about uranium reserves. Mineral reserves, known and unknown deposits, refer explicitly to the known amount of economically minable supplies of that mineral.
Discussion around them can be misleading, especially for a growing industry, because as a resource becomes more scarce, it becomes more economically viable to mine difficult deposits, this growing the reserve. On top of that, the effort and technology tend to yield new methods of both mining and refining that increase yields.
I don’t know natural disasters and war causing it to screw up also tends to worry people. Last time I checked wind and solar don’t create massive damage to the environment when destroyed.
It has been fifty years that “oh no they take so long to build, better never start” that by today we would have completely decarbonized energy generation if we started actually building them.
8 years to build, not 30. Instead we are building many many more coal and gas plants. What a terrific alternative. Fallacy of renewables without storage is done. It’s never going to happen.
But building new plants uses a shit ton of concrete. So we’re paying the carbon cost up front, and it can take years or even decades to break even.
That’s not remotely on the same scale, carbon-wise. Global output is like 4 billion tons of concrete per year, a nuclear plant uses like 12 tons per megawatt; an all-in nuclear buildout would use a tiny, tiny fraction of global concrete production and the carbon costs aren’t even remotely equivalent.
Hate to be the bearer of bad news, but this simply isn’t true with established nuclear technologies. Expanding our currently nuclear energy production requires us to fully tap all known and speculated Uranium sources, nets us only a 6% CO2 reduction, and we run out of Uranium by 2100. We might be able to use Thorium in fuel cycles to expand our net nuclear capacity, but that technology has to yet to be proven at scale. And all of this ignores the high startup cost, regulatory difficulties, disposal challenges and weapons proliferation risks that nuclear typically presents.
That’s an oversimplification to the point that it is wrong.
Nuclear power is not the only form of clean energy like that at all. It can not be scaled in this situation to save us, because it takes too long to build them.
It takes 6 years on a fast paced build. If we had started when we knew of the problem, we could have avoided some of the problem. It is the only energy source we can scale up in that way, however. Every other energy source takes longer for less yield with current technology.
It is not the only source like that at all. It is way easier, cheaper, faster and sustainable to build windmills where the is constant wind, solar cells where there is a lot of sun, hydro where there is… Energy sources should be built depending on the locality so they complement each other.
This kind of talking in absolutes like some of you are doing is just plain wrong and it does disservice to advocacy for nuclear power.
The best time to plant a tree is 20 years ago, but the second best time is today. We can’t let what we should have done stop us from doing what should be done.
And for other sources, wind and solar are great sources of energy that should be a supplement, but sometimes the wind doesn’t blow and the sun doesn’t shine, and we don’t currently have the battery technology to store energy on the scale to handle those fluctuations. We need a stable backup, and nuclear is by far the best clean and stable energy source.
Another person with the incredible wisdom to tell me the is no sun during the night.
Thank you sir!
I’ll make it quick:
Reducing carbon emissions is urgent. Building nuclear plants takes time, is expensive. There is no capacity to build enough to offset any carbon, not to mention building them produces carbon emissions. Plus many are even scheduled to be closed.
Building something that will make a difference 20 years from now is smart, but if it comes at the expense of what is urgent today, it is very very dumb.
Energy needs are only going to keep rising. Just build both FFS. Wind and solar is often built by private companies on their own initiative so with the right incentives the market can just go and build them. Government’s can put money towards nuclear so that we don’t need to have this same stupid tired argument in 20 years that we’ve been having for the last 20. It’s completely different industries and technical skills so it’s not as if doing one detracts from the other. Just start fucking building them.
It also doesn’t help that people got brainwashed that solar energy and heat pumps will solve all our problems. I don’t have enough space to install so many solar panels to provide power to heat pump during the Eastern European winter and even if I did, ROI will be longer than their expected lifetime. And we still use lead during production, and no one wants to recycle them. These geniuses here import broken solar panels and dump them into the ground and cover them, call that recycling. FFS, nuclear waste disposal is less scary than this uncontrolled shit.
Don’t you love it when you get heavily downvoted but no-one is brave enough to challenge your point of view?
I mostly agree with you. Solar is good if you own a house, with a roof and have thousands in disposable cash to invest, but that’s not most people.
Heat pumps can’t be run on your solar power alone and if your house isn’t well insulated, they can be extremely inefficient, ending up costing you substantially more than sticking with gas or oil. And that’s not getting in to the other short comings of heat pumps which I believe is a separate debate.
As many people in this thread have said, the best time to invest in nuclear was thirty years ago, but the next best time is now. Give us tonnes of cheap, carbon free electricity to throw in to a heat pump and then they make sense.
Just like assuming a perfectly spherical cow, or a frictionless surface, you can completely ignore the economics, the massive cost and schedule overages to make nuclear work.
Flamanville-3 in France started construction in 2007, was supposed to be operational in 2012 with a project budget of €3.3B. Construction is still ongoing, the in-service date is now sometime in 2024, and the budget has ballooned to €20B.
Olkiluoto-3 is a similar EPR. Construction started in 2005, was supposed to be in-service in 2010, but finally came online late last year. Costs bloated from €3 to €11B.
Hinkley Point C project is two EPRs. Construction started in 2017, it’s already running behind schedule, and the project costs have increased from £16B to somewhere approaching £30B. Start up has been pushed back to 2028 the last I’ve heard.
It’s no different in the US, where the V.C. Summer (2 x AP1000) reactor project was cancelled while under construction after projections put the completed project at somewhere around $23B, up from an estimate of $9B.
A similar set of AP1000s was built at Vogtle in Georgia. Unit 3 only recently came online, with unit 4 expected at the end of the year. Costs went from an initial estimate of $12B to somewhere over $30B.
Note that design, site selection, regulatory approvals, and tendering aren’t included in the above. Those add between 5-10 years to the above schedules.
Gee, I wonder if the cost might go down if we built more of them, as is the case with, y’know, basically every other complicated thing that humans build.
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.
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.
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.
Good!
Anti-nuclear is like anti-GMO and anti-vax: pure ignorance, and fear of that which they don’t understand.
Nuclear power is the ONLY form of clean energy that can be scaled up in time to save us from the worst of climate change.
We’ve had the cure for climate change all along, but fear that we’d do another Chernobyl has scared us away from it.
imagine how much farther ahead we would be in safety and efficiency if it was made priority 50 years ago.
we still have whole swathes of people who think that because its not perfect now, it cant be perfected ever.
So uh, turns out the energy companies are not exactly the most moral and rule abiding entities, and they love to pay off politicians and cut corners. How does one prevent that, as in the case of fission it has rather dire consequences?
Big news worthy accidents are a really good way to ensure strong regulation and oversight. And nuclear is very regulated now so that it has lower death rate than wind power.
Since you can apply that logic to everything, how can you ever build anything? Because all consequences are dire on a myopic scale, that is, if your partner dies because a single electrician cheaped out with the wiring in your building and got someone to sign off, “It’s not as bad as a nuclear disaster” isn’t exactly going to console them much.
At some point, you need to accept that making something illegal and trying to prosecute people has to be enough. For most situations. It’s not perfect. Sure. But nothing ever is. And no solution to energy is ever going to be perfect, either.
a wind mill going down and a nuclear plant blowing up have very different ramifications
Exactly, just like a windmill running and a nuclear power plant running have very different effects on the power grid. Hence why comparing them directly is often such a nonsense act.
The risks are lower in literally everything else…?
An electrician installing faulty wiring doesn’t render your home uninhabitable for a few thousand years.
So there’s one difference.
That’s why there are lots of regulations for things impacting life safety. With a nuclear power plant, you mitigate the disaster potential by having so many more people involved in the design and inspection processes.
The risk of an electrician installing faulty wiring in your home could be mitigated by having a third party inspector review the work. Now do that 1000x over and your risk of “politicians are paid off” is negligible.
You are saying, regulations will fix this? Politicians create the regulations, the fines, and enforcement.
Political parties are running on platforms of deregulation right now.
Regulations are actually generally created by regulatory bodies, which are usually non-political. For instance, the underwriter laboratory is the major appliance, building and electrical approval body in the United States.
In most countries, building codes and safety codes are created by industry specialists, people who have been in the industry as professionals for many decades and have practiced and been licensed in the field that they are riding the regulations for.
There’s a big difference between politicians who are passing these laws, and those writing them who are the regulatory bodies. Generally, as a politicians will simply adopt the codes as recommended by the professional licensing and certification bodies.
I suppose it will be the end of modern civilization if politicians decide to politicize electrical or building codes. Then we’ll be fucked for sure. We’ve seen that happen before with the Indiana pi bill.
https://en.m.wikipedia.org/wiki/Indiana_Pi_Bill
“The Indiana Pi Bill is the popular name for bill #246 of the 1897 sitting of the Indiana General Assembly, one of the most notorious attempts to establish mathematical truth by legislative fiat.”
Regulations that a lot of pro-nuclear people try to get relaxed because they “artificially inflate the price to more than solar so that we’ll use solar”. I’m not saying all pro-nuclear folks are tin-foilers, but the only argument that puts nuclear cheaper than solar+battery anymore is an argument that uses deregulated facilities.
If solar+wind+battery is cheaper per MWH, faster to build, with less front-loaded costs, then it’s a no-brainer. It only stops being a no-brainer when you stop regulating the nuclear plant. Therein lies the paradox of the argument.
Okay, so we’ve got a safe nuclear power plant that’s a decade behind schedule and 100% over budget.
Because the energy industry is historically the one lobbying governments for less regulation. Also, has there ever been a nuclear project in the history of mankind that didnt result in depleted Uranium leeching into local watertables and/or radioactive fallout? Your comment is basically tacit acceptance that people are going to act unethically, which, in regards to nuclear power, is bound to have human consequences.
Easy. Have nuclear power plants operate as government run and backed corporations (what we’d call a “Crown Corporation” here in Canada).
That way you can mandate safety and uptime as metrics over profit. It may be less efficient from an economic standpoint (overall cost might be higher), but you also don’t wind up with the nuclear version of Love Canal.
Much much tighter regulations. Our cars aren’t aluminum cans waiting to crush everybody inside them because of strict safety regulations.
Nationalise energy production.
Or they could just allow everyone to build nuclear reactors in their backyard, everyone is saying that they are safer than a banana so i don’t see any issue
I mean it’s not the companies operating the facilities we put our trust in, but the outside regulators whose job it is to ensure these facilities are safe and meet a certain standard. As well as the engineers and scientists that design these systems.
Nuclear power isn’t 100% safe or risk-free, but it’s hella effective and leaps and bounds better than fossil fuels. We can embrace nuclear, renewables and fossil free methods, or just continue burning the world.
Don’t push nuclear power like it’s the only option though.
Where I live we entirely provide energy from hydro power plants and nuclear energy is banned. We use no fossil fuels. We have a 35 year plan for future growth and it doesn’t include any fossil fuels. Nuclear power is just one of the options and it has many hurdles to implement, maintain and decommission.
My country, Sweden, also gets a decent chunk of power from hydro. Back in 2021, about 43% was hydroelectric, and 31% was nuclear.
Honestly, if you can, hydro is brilliant. Not many places can though — both because of geography and politics. Nuclear is better than a lot of the alternatives and shouldn’t be discounted.
And what do YOU know about radioactive waste disposal?
I know it’s a damn lot easier than carbon recapture, if we’re talking waste products. It’s not ideal, but there is no such thing as perfect, and we shouldn’t let that be the enemy of good. Nuclear fission power is part of a large group of methods to help us switch off fossil fuels.
“Easier”? Are you aware of the fact that radioactive waste tombs are meant to stand for millions of years? It requres a lot of territory, construction and servance charges, and lots of prays for nothing destructive happens with it in its “infinite” lifetime.
Launch it into the sun or Florida
Launching radioactive waste into space is a terrible idea, because rockets on occasion crash. Once that happens it becomes a nuclear disaster.
Instead we can safely store it in depleted mines.
The problem is its potential for harm. And I don’t mean meltdown. Storage is the problem that doesn’t seem to have strong solutions right now. And the potential for them to make a mistake and store the waste improperly is pretty catastrophic.
“Nuclear waste” sounds super scary, but most of it are things like tools and clothing, that have comparatively tiny amount of radioactivity. Sure it still needs to be stored properly, very little high level waste is actually generated.
You know what else is catastrophic? Fossil fuels and the impact they have on the climate. I’m not arguing that we should put all our eggs in one basket, but getting started and doing something to move away from the BS that is coal, gas, and oil is really something we should’ve prioritised fifty years ago. Instead they have us arguing whether we should go with hydroelectric, or put up with “ugly windmills” or “solar farms” or “dangerous nuclear plants.”
It’s all bullshit. Our world is literally on fire and no one seems to actually give a fuck. We have fantastic tools that could’ve halted the progress had we used them in time, but fifty years later we’re still arguing about this.
At this point I honestly hope we do burn. This is a filter mankind does not deserve to pass. We’re too evil to survive.
Yea both are horrible. But we can get off fossil fuels and walk away. We can’t with nuclear. It’ll always be with us and doesn’t solve that we need fossil fuel for other things.
Jets and ships are still going to need fossil fuels.
Which is why I think the best thing we could be doing right now is focusing on improving how energy is store. With the right advancement we could solve a lot of these problems with the right battery.
Mercury will always be with us. Arsenic will always be with us. PFAS will always be with us. Natural radiation will always be with us. Fortunately, nuclear waste is easily detectable, the regulations around it are much stronger, the amount of HLW is miniscule and the storage processes are incredibly advanced
Moreover, most Nuclear waste won’t always be with us. A lot of fission prodcuts have half lives in the decades or centuries
Jets and ships can be nuclear powered. It’s just not a very good idea for jets at least.
Sure, but doesn’t that just increase the nuclear waste storage issue if we turn all these vehicles nuclear powered
The worst nuclear disaster has led to 1,000sq miles of land being unsafe for human inhabitants.
Using fossil fuels for power is destroying of the entire planet.
It’s really not that complicated.
Except that nuclear isn’t the only, or even the cheapest, alternative to fossil fuels.
Except that powering the world with nuclear would require thousands of reactors and so much more disasters. This doesn’t even factor the space abandonned to store «normal» toxic materials.
You mean under ground from where it was dug out?
The plant itself, water inevitably getting in contact with wastes and leaking also.
You mean water under ground? It was in contact million years before any of us was born.
Both sound terrible.
I don’t really want to pick the lessor of two evils when it comes to the energy.
By not picking, you are picking fossil fuels. Because we can’t fully replace everything with solar/wind yet, and fossil fuels are already being burned as we speak.
No, give me an option that doesn’t make a part of the world uninhabitable or increases climate change.
That just a stupid comparison and is there any reason why we can’t also do wind solar thermal hydro also? It’s fossil fuels or nuclear and that’s it?
No, give me an option that doesn’t make a part of the world uninhabitable or increases climate change.
That just a stupid comparison and is there any reason why we can’t also do wind solar thermal hydro also? It’s fossil fuels or nuclear and that’s it huh?
We are on a time limit thanks to climate change. We can’t afford to complain about picking the lessor of two evils.
The option proposed is that making a small area of the planet inhabitable or worsening climate change. Sorry but that’s a shitty comparison.
Bet you’d feel* differently if you were a resident of one of the island nations that’s going to drown in the next decade or two. That part of the world’s definitely going to be uninhabitable if we continue to do nothing.
How do you get the uranium or thorium? Generally, it has to be mined. Are we using nuclear powered mining equipment? No. We use fossil fuel powered mining equipment. Then we use fossil fuels to power the trucks that take the depleted nuclear product to the storage depot, which is powered and requires employees who drive there using fossil fuel powered vehicles, using fossil fuel powered warehouse equipment. When does nuclear power phase out the fossil fuel power? Are we going to decommission oil and coal production facilities? Or are we just going to use nuclear to augment the grid?
Don’t forget all the fossil fuels used in machinery that builds nuclear power plants, and the CO2 emissions from all of the concrete used.
Oh, and if you start building a nuclear power plant right now it will be online (maybe) in a decade or two and hopefully for only 150% of the initial cost. There’s a nuclear power plant in Georgia that is $17 BILLION over budget.
So basically saving the planet is mega super important, but somehow 17 billions is suddenly too much?
That $17 billion could be spent on renewables that produce cheaper electricity and be online in less than 20 years.
How much renewables do you get for $17B?
And we would be expecting these corrupt Cost cutting types to warehouse nuclear waste for hundreds if not thousands of years while requiring regular inspections and rotation of caskets periodically while also maintaining the facilities. All of that for a product that doesn’t produce any value, it just sits there and accumulates.
And where does it get stored? Right now almost 100% of waste is stored on site above ground because they really have no good solution. People will say things like “its just a little bit of toxic waste” or “its cool because we could use it in process we don’t have yet but might in the future” and all I can think of is how this was the same thinking that got us into our dependence on our first environmental catastrophic energy source. I’m not confident we that scaling up to another one will end well.
You mean there’s so little they don’t even need a dedicated facility for it, and it’s safe enough that people are willing to work where it’s stored? Sounds great!
Is it quote from 60-ies? We have. At least Russia has. US had too.
If the Soviets hadn’t cut corners and Chernobyl hadn’t happened in this first place, this is likely where we would already be.
One reason it wasn’t made a priority 50 years ago is because Jimmy Carter - a nuclear submariner who understood the risks and economics - decided it wasn’t a good idea.
This is a man who was present at a minor nuclear accident, who helped create the modern nuclear submarine fleet, acknowledging that nukes weren’t going to help during the height of the Oil Embargo.
emphasis mine:
First of all anti- #GMO stances are often derived from anti-Bayer-Monsanto stances. There is no transparency about whether Monsanto is in the supply chain of any given thing you buy, so boycotting GMO is as accurate as ethical consumers can get to boycotting Monsanto. It would either require pure ignorance or distaste for humanity to support that company with its pernicious history and intent to eventually take control over the world’s food supply.
Then there’s the anti-GMO-tech camp (which is what you had in mind). You have people who are anti-all-GMO and those who are anti-risky-GMO. It’s pure technological ignorance to regard all GMO equally safe or equally unsafe. GMO is an umbrella of many techniques. Some of those techniques are as low risk as cross-breeding in ways that can happens in nature. Other invasive techniques are extremely risky & experimental. You’re wiser if you separate the different GMO techniques and accept the low risk ones while condemning the foolishly risky approaches at the hands of a profit-driven corporation taking every shortcut they can get away with.
So in short:
The daft thing is that even if another Chernobyl happened (unlikely given superior technology and safety standards) it wouldn’t be anywhere near as damaging as climate change.
The radiation would only affect a small area of the planet not the whole world, and technically radiation doesn’t even cause climate damage. Chernobyl has plenty of trees and plenty of wildlife, it’s just unsuitable for human habitation.
Here’s my favorite way to put it: because of trace radioactive elements found in coal ore, coal-fired power plants produce more radioactivity in normal operation than nuclear power plants have in their entire history, including meltdowns. And with coal, it just gets released straight into the environment without any attempt to contain it!
And that’s just radioactivity, not all the other emissions of coal plants.
This is a fun fact but I don’t think it matters, no one is getting radiation sickness from coal smoke. Don’t misunderstand me, I’m not saying coal smoke is healthy, it’s fucking awful and causes way more deaths than nuclear power plants.
Federation of American scientists (FAS) believe that the number is actually calculable:
https://rlg.fas.org/mwmt-p233.pdf
That’s about the number of people who died from Chernobyl, every year. From the radiation from coal power plants.
I totally agree that current nuclear power generation should be left running until we have enough green energy to pick up the slack, because it does provide clean and safe energy. However, I totally disagree on the scalability, for two main reasons:
Current nuclear power generation is non-renewable. It is somewhat unclear how much Uranium is available worldwide (for strategic reasons), but even at current production, supply issues have been known to happen. And it goes without saying that waiting to scale up some novel unproven or inexistent sustainable way of nuclear power production is out of the question, for time and safety reasons. Which brings me to point 2.
We need clean, sustainable energy right now if we want to have any chance of fighting climate change. From start of planning of a new nuclear power plant to first power generation can take 15 or 20 years easily. Currently, about 10% of all electricity worldwide is produced by about 400 nuclear reactors, while around 15 new ones are under construction. So, to make any sort of reasonable impact, we would have to build to the tune of 2000 new reactors, pronto. To do that within 30 years, we’d have to increase our construction capacity 5 to 10 fold. Even if that were possible, which I strongly doubt, I would wager the safety and cost impacts would be totally unjustifiable. And we don’t even have 30 years anymore. That is to say nothing of regulatory checks and maintenance that would also have to be increased 5 fold.
So imho nuclear power as a solution to climate change is a non-starter, simply due to logistical and scaling reasons. And that is before we even talk about the very real dangers of nuclear power generation, which are of course not operational, but due to things like proliferation, terrorist attacks, war, and other unforseen disruptions through e.g. climate change, societal or governmental shifts, etc.
Nuclear fission using Uranium is not sustainable. If we expand current nuclear technologies to tackle climate change then we’d likely run out of Uranium by 2100. Nuclear fusion using Thorium might be sustainable, but it’s not yet a proven, scalable technology. And all of this is ignoring the long lead times, high costs, regulatory hurdles and nuclear weapon proliferation concerns that nuclear typically presents. It’d be great if nuclear was the magic bullet for climate change, but it just ain’t.
We’d run of our uranium that’s economical to extract using current technology and at current prices. All known mineral reserves could power the world on exclusively nuclear energy for several thousand years at least.
You got a source for that? Because the one I linked says that we run out of known Uranium deposits by 2100 at current usage rates. Our known Uranium deposits run out mid-century if we use nuclear to follow the IEA Blue Map plan to reduce carbon emissions by 50%, and we run out of even speculated deposits by 2100 under that scenario. Where are you getting “several thousand years” from? Is Thorium part of the mineral reserves to which you’re referring?
The source you linked talks about uranium reserves. Mineral reserves, known and unknown deposits, refer explicitly to the known amount of economically minable supplies of that mineral.
Discussion around them can be misleading, especially for a growing industry, because as a resource becomes more scarce, it becomes more economically viable to mine difficult deposits, this growing the reserve. On top of that, the effort and technology tend to yield new methods of both mining and refining that increase yields.
I don’t know natural disasters and war causing it to screw up also tends to worry people. Last time I checked wind and solar don’t create massive damage to the environment when destroyed.
Ahh… no. New solar and wind generation can be spun up much faster than nuclear.
Except the plants take so long to build they won’t be ready until we’re at 2°C
It has been fifty years that “oh no they take so long to build, better never start” that by today we would have completely decarbonized energy generation if we started actually building them.
We could have also built solar collectors in orbit and beamed carbon-free electricity to Earth if we started 50 years ago.
Heck, if we funded fusion research properly there’s a good chance we’d have had that by the mid 90s
Long term nuclear is great…
But building new plants uses a shit ton of concrete. So we’re paying the carbon cost up front, and it can take years or even decades to break even.
So we can’t just spam build nuke plants right now to fix everything.
30 years ago that would have worked.
8 years to build, not 30. Instead we are building many many more coal and gas plants. What a terrific alternative. Fallacy of renewables without storage is done. It’s never going to happen.
That’s not remotely on the same scale, carbon-wise. Global output is like 4 billion tons of concrete per year, a nuclear plant uses like 12 tons per megawatt; an all-in nuclear buildout would use a tiny, tiny fraction of global concrete production and the carbon costs aren’t even remotely equivalent.
(also, wind power uses way, way more concrete)
Hate to be the bearer of bad news, but this simply isn’t true with established nuclear technologies. Expanding our currently nuclear energy production requires us to fully tap all known and speculated Uranium sources, nets us only a 6% CO2 reduction, and we run out of Uranium by 2100. We might be able to use Thorium in fuel cycles to expand our net nuclear capacity, but that technology has to yet to be proven at scale. And all of this ignores the high startup cost, regulatory difficulties, disposal challenges and weapons proliferation risks that nuclear typically presents.
That’s an oversimplification to the point that it is wrong. Nuclear power is not the only form of clean energy like that at all. It can not be scaled in this situation to save us, because it takes too long to build them.
It takes 6 years on a fast paced build. If we had started when we knew of the problem, we could have avoided some of the problem. It is the only energy source we can scale up in that way, however. Every other energy source takes longer for less yield with current technology.
Sadly, humanity had other things to do :(
Yep. Fuck Putin.
If we had started, but we didn’t.
It is not the only source like that at all. It is way easier, cheaper, faster and sustainable to build windmills where the is constant wind, solar cells where there is a lot of sun, hydro where there is… Energy sources should be built depending on the locality so they complement each other.
This kind of talking in absolutes like some of you are doing is just plain wrong and it does disservice to advocacy for nuclear power.
The best time to plant a tree is 20 years ago, but the second best time is today. We can’t let what we should have done stop us from doing what should be done.
And for other sources, wind and solar are great sources of energy that should be a supplement, but sometimes the wind doesn’t blow and the sun doesn’t shine, and we don’t currently have the battery technology to store energy on the scale to handle those fluctuations. We need a stable backup, and nuclear is by far the best clean and stable energy source.
Another person with the incredible wisdom to tell me the is no sun during the night. Thank you sir!
I’ll make it quick: Reducing carbon emissions is urgent. Building nuclear plants takes time, is expensive. There is no capacity to build enough to offset any carbon, not to mention building them produces carbon emissions. Plus many are even scheduled to be closed.
Building something that will make a difference 20 years from now is smart, but if it comes at the expense of what is urgent today, it is very very dumb.
Energy needs are only going to keep rising. Just build both FFS. Wind and solar is often built by private companies on their own initiative so with the right incentives the market can just go and build them. Government’s can put money towards nuclear so that we don’t need to have this same stupid tired argument in 20 years that we’ve been having for the last 20. It’s completely different industries and technical skills so it’s not as if doing one detracts from the other. Just start fucking building them.
It also doesn’t help that people got brainwashed that solar energy and heat pumps will solve all our problems. I don’t have enough space to install so many solar panels to provide power to heat pump during the Eastern European winter and even if I did, ROI will be longer than their expected lifetime. And we still use lead during production, and no one wants to recycle them. These geniuses here import broken solar panels and dump them into the ground and cover them, call that recycling. FFS, nuclear waste disposal is less scary than this uncontrolled shit.
Don’t you love it when you get heavily downvoted but no-one is brave enough to challenge your point of view?
I mostly agree with you. Solar is good if you own a house, with a roof and have thousands in disposable cash to invest, but that’s not most people.
Heat pumps can’t be run on your solar power alone and if your house isn’t well insulated, they can be extremely inefficient, ending up costing you substantially more than sticking with gas or oil. And that’s not getting in to the other short comings of heat pumps which I believe is a separate debate.
As many people in this thread have said, the best time to invest in nuclear was thirty years ago, but the next best time is now. Give us tonnes of cheap, carbon free electricity to throw in to a heat pump and then they make sense.
Just like assuming a perfectly spherical cow, or a frictionless surface, you can completely ignore the economics, the massive cost and schedule overages to make nuclear work.
Flamanville-3 in France started construction in 2007, was supposed to be operational in 2012 with a project budget of €3.3B. Construction is still ongoing, the in-service date is now sometime in 2024, and the budget has ballooned to €20B.
Olkiluoto-3 is a similar EPR. Construction started in 2005, was supposed to be in-service in 2010, but finally came online late last year. Costs bloated from €3 to €11B.
Hinkley Point C project is two EPRs. Construction started in 2017, it’s already running behind schedule, and the project costs have increased from £16B to somewhere approaching £30B. Start up has been pushed back to 2028 the last I’ve heard.
It’s no different in the US, where the V.C. Summer (2 x AP1000) reactor project was cancelled while under construction after projections put the completed project at somewhere around $23B, up from an estimate of $9B.
A similar set of AP1000s was built at Vogtle in Georgia. Unit 3 only recently came online, with unit 4 expected at the end of the year. Costs went from an initial estimate of $12B to somewhere over $30B.
Note that design, site selection, regulatory approvals, and tendering aren’t included in the above. Those add between 5-10 years to the above schedules.
Gee, I wonder if the cost might go down if we built more of them, as is the case with, y’know, basically every other complicated thing that humans build.
That is factually false information. There are solid arguments to be made against nuclear energy.
https://isreview.org/issue/77/case-against-nuclear-power/index.html
Even if you discard everything else, this section seems particularly relevant:
https://www.dw.com/en/fact-check-is-nuclear-energy-good-for-the-climate/a-59853315
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.
when is the best time to plant a tree? 30 years ago. When is the second best time? now.
Surely the second best time would have been 29 years ago
Don’t fuck this up for me bro
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.
So just hire them. Too bad they lost almost all of their institutional knowledge about nuclear construction compared to what they used to have.
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.

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?
probably technicians falling off is the biggest thing

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.
Your not counting the indirect deaths.

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.

Thank you. The pro-nuclear bullshit from Reddit seems to be spilling over.
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.
