First U.S. nuclear reactor built from scratch in decades enters commercial operation in Georgia::ATLANTA — A new reactor at a nuclear power plant in Georgia has entered commercial operation, becoming the first new American reactor built from scratch in decades.
Good news. Anything but fossil fuels at this point.
The reduced operating emissions take 10+ years to outweigh the enormous construction emissions of nuclear. (Compared to gas.)
Fortunately the nuclear reactor can be operated for >50 years :)
Mean and median lifetime of a nuclear reactor is well under 30 years. Closer to 20 if you count all the ones that produced for 0 years.
Sure. But do you think Nuclear reactors will still be cheaper than renewables + storage in the 2070s? Nuclear is far more expensive per kWh than renewables, and the cost of storage is falling fast.
Good question, that one can only speculate on. IMO it’s a two part question.
First is that newly built nuclear plants are expensive. So the question depends on if we bite the bullet (build the reactor) today or in 2070. One built today will produce cheap power in 50 years.
For example in Finland we have reactors from 1980, that make up the backbone of stable energy production in our country. Those are going to be kept online till the 2050s. I’d argue at that point the cost per kwh will be mostly dependent on maintenance and fuel, so relatively small.
Wind and solar cannot reap the same benefits if you have to replace the plant every 20 years.
Storage is a completely separate question that is not taken into account when new wind farms and such are being built. If one was to account for storage today, the cost of renewables would be much closer to that of other means of production.
Also in the future, if storage costs keep falling due to billions of R&D money, similar effects could be achieved in nuclear via serial production and scale.
EDIT: Just read you have studied this stuff for real. Then ignore most of what I said, as you might know better :D
You can’t amortise your capital if just the variable operating and maintenance is more than replacing the reactor with firmed renewables. This is not the case yet, but betting that renewables won’t halve in price one more time in 30 years is a pretty stupid bet.
I would say it’s not the BEST solution but in areas in the extreme north/south, where solar/hydro aren’t options (and I legit have no idea how well wind would do with freezing weather/snow etc) it would be better to have nuclear there than to try and transmit long distance to those areas. At least until we get some more breakthroughs in energy storage.
It was started a decade ago and finished now, not in the 2070s

I literally studied this exact nuclear design at University - the Westinghouse AP1000. You can look up the WNISR (World Nuclear Industry Status Report) if you don’t want to take my word for it.
Don’t forget, mining and enriching uranium still has a significant carbon footprint, far higher per tonne than any fossil fuel. Yes, it’s lower over time, but we need to be reducing emissions now, not in 50 years time.
Yeah I hate how laxness about fixing this in a timely manner has somehow convinced some people that shit like “carbon nuetral by 2070” is ok and helpful. And I’m just remembering when that study came out that said the climate as we know it is probably gone forever if we aren’t totally carbon nuetral by at least 2030

Why are you comparing fossil fuels and nuclear “per tonne” that makes no sense. You replace tens of tones of nuclear fuel per year any you burn millions of tones in a comparable fosil fuel plant.
And regarding the carbon emissions from enrichment… Just use nuclear to power your enrichment plants. This way your emissions are extremely low because you don’t need much fuel and you use nuclear energy to produce nuclear fuel. French example: https://en.m.wikipedia.org/wiki/Tricastin_Nuclear_Power_Plant
Why compare per ton of fuel when per kWh would be the more meaningful metric?
What are the cradle-to-grave emissions of a nuclear plant, vs a fossil fuel plant, per kWh generated. That is a far more honest question, and I’m inclined to err on the side of nuclear.
Let’s not forget radiation caused by the power plant. Nuclear produces far less radiation than a coal plant.
deleted by creator
So you’re saying the construction effort requires at least a decade of nuclear powered energy to be achieved?
That could be up to 3.652 TWh. That’s more than my entire nation consumes in three years and we’re one of the world’s biggest suppliers of natural resources, including nuclear.
You’re mathing wrong.
Nuclear is still fossil fuel, just not combustion. But I agree, this is good news because it helps reduce coal and gas usage.
Edit: I get it, I’m wrong. No need to repeat the same comments over and over.
I’m confused by your definition of fossil fuels.
It’s the fossils of stars.
Nuclear is Non-renewable, but it’s not a Fossil fuel:
A hydrocarbon-based fuel, such as petroleum, coal, or natural gas, derived from living matter of a previous geologic time.
We have plenty of nuclear fuel and waste is a drop in an ocean compared to that of fossil fuels.
Yep. This is why I’m annoyed the UK is dumping its money into oil and coal fuel sources. We need more Nuclear plants and we should have started building these yesterday.
The best time to
plant a treebuild a nuclear power plant was 20 years ago. The second best time is now.Tory government investing in nuclear energy?
Nah boris and his lot would rather get bungs from the local lads and keep us in the dark ages.
Labour aren’t exactly gonna do it either with Tory lite candidates atm. We are well and truly proper fucked.
I’d prefer it if my nuclear waste doesn’t drip into the ocean, please /s
I asked for that. In a manner-of-speaking, if you compared by the football field filled in area with barrels of waste. It would be about one for all the annual nuclear waste where turning the byproduct of combustible fossil fuels into just the vapor and ash equivalent would fill thousands. It arguably wouldn’t win from a toxicity perspective. For all the waste in the ocean from Fukushima, the only outcome were that the marine life seemed to have thrived off the low-level radiation.
What’s your favorite dinosaur? Mine is the Plutonidon

Ooh a lot of people here seem very pro-nuclear-power. That’s cool!
Unfortunately, there’s still that one guy in the comments trying to say that hypothetical, largely unproven solutions are better for baseload than something that’s worked for decades.
That or the fear-mongering talking points. That’s what caused our local power plant to be decommissioned, and now those same people are complaining about how much their electrics cost now.
The old soviet legacy. And a bit of actual disasters and from the 2 significant ones (hiroshima and chernobyl) half are beacuse of the soviets.
*Fukushima
Hiroshima was the freedom bombing disaster
on a side notw how people have dies from fukushima in the years since and how many have died from coal? Also you can compare the number of long term health problems
Doesn’t matter. Bad news at the time was enough to scare people for the next 30 years.
Heck, even my college Sociology textbook from OpenStax basically has nuclear fear-mongering baked into one of the later sections.
some people can’t help but cut their nose to spit their face
I think you mean hypothetical technology that hasn’t been invented yet, but he expected will be in widespread use 50 years from now.
The nuclear lobby is alive and well on social media. Never before has the internet apparently agreed on something so controversial with some of the most cookie cutter, copy and paste, AI generated comments on the subject I’ve ever seen.
The talking points seem to gloss over the fact that nuclear storage always fails, meltdowns happen, and you still have to mine uranium out of the ground. It’s far from a clean source of energy.
That the “nuclear lobby” is paying people to post stuff on Lemmy, a social media platform that accounts for a small part of single percent of all social media users, is a hot take I haven’t heard yet. Congrats, you’ve definitely imagined a scenario that nobody else in history has ever thought of. A true original thought.
Pity it’s an absolutely fucking brain dead take masquerading as something more than nonsensical blithering from a total nincompoop, but you should bask in this moment nonetheless.
Nuclear power is something we should be using if you support science. If you don’t support science well you have a lot of other problems. Nuclear and renewable energy both need massive investments at the same time to replace fossil fuels.
It’s not the cleanest, but in term of CO2 and other toxics produced per Giga-Watts, it’s the best compromise.
Fission is hopefully, coming in the next decades. Like the other guy said, anything but coal/petrol.
About damn time! As a Georgia Power ratepayer, I’ve only already been paying extra for it for what, around a decade now?
That’s the downside of nuclear. Cost and build time. Upside is it’s reliable and carbon-clean.
The best time to build a nuclear power plant was thirty years ago. The second best time is now.
They took the average of that and built it 10 years ago
The 1.3th best time to build a nuclear power plant was 10 years ago
This encapsulates the public response to building nuclear. I guess that is why it is the first in decades.
To be clear, my comment isn’t “the public response to building nuclear;” it’s “the public response to corruptly financing nuclear on the backs of ratepayers while guaranteeing zero-risk profit for shareholders, despite incredible incompetence and cost overruns building the thing.”
If you think that bullshit is inherent to building nuclear, I won’t dispute it, but I will say it makes you even more cynical than me!
I would’ve had no problem with it at all if it weren’t a fucking scam to gouge me for somebody else’s profit.
Whoa. Finally a state in the US that isn’t doing something completely ass backwards. We need more of this.
It’s Georgia, though. This is a positive development but it barely begins to make up for how much other ass-backwards stuff there is.
This is the state that elected Marjorie Taylor Greene, keep in mind.
A single congressional district within that state elected Marjorie Taylor Greene lol
Hmm if we had a giant solar array in space that could continuously capture sunlight, we could connect it to the Jewish Space Laser™ and beam it down to Earth, hopefully to a collection panel and not to the California forests to cause wildfires.
Hopefully Georgia steps up and sticks to their guns with prosecuting people who attempt to convince election officials “to find 11,780 votes”.
This is the state that brought you Biden in 2020. And two democratic senators. Granted there’s a lot of back ass districts here, but we’re working on it I promise.
That seems completely forgivable when compared to Florida and the men they keep electing governor of that state.
I highly, highly recommend the Oliver Stone documentary Nuclear Now from earlier this year. Completely changed my perspective. I had no idea that the oil industry was behind so much of the fear mongering around nuclear.
Oh, neat. My state did something not completely stupid. I’ve got some reservations about nuke power as opposed to renewable, but this is definitely better than continuing fossil fuels.
Fission and fusion reactors are really more like in-between renewable and non-renewable. Sure, it relies on materials that are finite, but there is way, way more of that material available in comparison to how much we need.
Making this distinction is necessary to un-spook people who have gone along with the panic induced by bad media and lazy engineering of the past.
Fusion and fission are quite different. A practical fusion reactor does not exist. It’s outside our technological capability right now. Current fusion reactors are only experimental and can not maintain a reaction more than a small fraction of a second. The problem is plasma containment. If that can be solved, it would be possible to build a practical fusion reactor.
The fuel for a working fusion reactor would likely be deuterium/tritium which is in effect unlimited since it can be extracted from seawater. Also the amount of fuel required is small because of the enormous amounts of energy produced in converting mass to energy. Fusion converts about 1% of mass to energy. Output would be that converted mass times the speed of light squared which is a very, very large number, in the neighborhood of consumed fuel mass times 1015.
Fusion is far less toxic to to the environment. With deuterium/tritium fusion the waste product is helium. All of the particle radiation comes from neutrons which only require shielding. Once the kinetic energy of the particles is absorbed, it’s gone. There’s no fissile waste that lingers for some half life.

Here’s something more interesting. A matter-antimatter reactor converts 100% of mass to energy so it’s a hundred times more efficient than fusion. In modern times antimatter has been produced at quantum levels in large accelerators such as the Hadrian collider. So it does in fact exist and can be produced.
However a matter-antimatter reactor has some serious technical problems. For one it’s currently impossible to create antimatter in any practical quantity. Second if antimatter comes in contact with matter, instant boom. Like a sugar cube size of the stuff could level a large city. So containment would be an insurmountable problem.
The interesting part is when you see an antimatter reactor in shows like Star Trek, it’s based on real science. Interestingly in 1968 when they wrote the original Star Trek, nobody knew antimatter was a physically real thing. That’s a case of sci-fi predicting science.
deleted by creator
But antimatter needs energy to create, probably more energy than it can produce. Unless you can find some source of it in the environment. Fusion is much more likely to be feasible.
Antimatter might make a good compact way to store energy for a starship, if it was created in a large fixed facility with access to huge power sources. But it’s not a way to generate energy by itself.

Your info is a little out of date - some fusion experiments have been able to maintain fusion for almost a minute. However, your point still stands. We are decades away at a minimum untill a viable fusion reactor.
My guess is that fusion will be too expensive for commercial use unless they can get a super compact stellarator design to produce huge amounts of energy, and make them cheap to build (HA!).
Or we will see them in spaceships. :P
LWR fuel is incredibly limited without a massive fleet of breeders (and no breeder has ever run a full fuel cycle, nor has second generation MOX ever been used. First generation MOX is also incredibly polluting and expensive to produce).
The industry is already on to tapping uranium ore sources that are less energy dense than coal, and this is to provide a few % of world energy for a handful of decades.
Sure, it relies on materials that are finite, but there is way, way more of that material available in comparison to how much we need.
Not trying to be “difficult,” but isn’t that what people thought about coal/oil at first? I understand that the scale is different, but it still needs to be a stop gap as opposed to a long term plan.
Spent Nuclear Fuel, unlike coal or oil, can be recycled to a certain extent (this is done in places like France but not the US). If we recycled all of the spent fuel, we’d potentially have a thousand years (give or take) of fissionable fuel. Plenty of time for us to get fusion running so we can completely wean ourselves off petroleum energy generation.
billions if we start using thorium
So far the problem, if I understand correctly, is all thorium reactors are molten salt reactors. The issue there is, we still haven’t solved the metallurgy problems of dealing with the corrosive salt. It destroys all the pipes. We have slowed it down, but not enough to go production with.
How fast are talking. Like replace the pipes evety year or they breakbdown in months
I don’t have an answer for that question unfortunately
By that time I’m hoping we’d be using Deuterium-Tritium fusion for all our needs. Or go full scale megaengineering and Dyson Sphere some star somewhere.
You’re conflating leftover dregs of Pu-239 (about a 10-15% boost in energy per fuel input) with non-fissile material like U238. Breeder reactors required to use the second have never been used commercially in breeding mode.
You’ve either fallen for or are intentionally spreading a lie.
What lie am I spreading? Conventional Light Water Reactor Nuclear Fuel (5-6% U-235 w/t%) can be recycled. This can be done even without using breeder reactors which operate through fast fission of U-235
Yes the plutonium can be stripped out along with the other transuranics, and it does pose a proliferation risk (separate issue), but it definitely can be recycled. France reprocesses their fuel.
Edit: typo correction
Ah. So intentional then. You’re trying to pretend extracting the <0.7% left over U235 and Pu239 (for a 10-15% increase in U235 fuel economy) is somehow fissioning U238.
I don’t understand what you’re trying to say here. Reprocessed fuel does not imply that we’re now fissioning U-238. That takes place in a completely different energy regime (fast fission vs. thermal). Light Water Reactors and fast reactors operate differently, with different fuels. LWRs in commercial operation use slightly enriched U-235. There is no fissioning of U-238 other than the very small amount of spontaneous fission which is negligible compared to contributions from thermal fission in an LWR. The Six Factor formula governs criticality reactions, and these terms differ for both reactor types. The nuclear cross sections are fundamentally different between these energy regimes.
Reprocessed fuel is what it implies, recycled processed LWR fuel, stripped of the fission products that built up as the fuel underwent burnup in the core. If this were some sort of pretend activity then I guess the entire reprocessing back end of the nuclear fuel industry is fake.
I don’t appreciate the personal attacks, so if you have nothing constructive to say, good day to you sir slash madam.
U-238 is largely stable and has the consistency of metal, making it easy to store or sequester away. Most natural deposits of Uranium are U-238.
Additionally you can make a breeder reactor that bombards U-238 to make U-239 which has a half life of 23+ minutes and decays into Plutonium-239 which can be used in nuclear power generation.
If we can pull off hydrogen fusion without crazy radioactive isotopes I reckon we can go on for a little while without having to worry about running out of hydrogen in the solar system / galaxy
Instead we only have to worry about immediately running out of beryllium for breeding blankets just on the demo reactors.
We don’t even know if fusion will ever be functionally able to produce more energy than it consumes, and on top of that it will need to be less expensive than natural gas or solar in order to compete. Which it will never do. Do you have any idea how much ITER has cost?
$22 billion, or $16 billion “over budget.” And this is a test reactor that will never produce commercial power. They still have 2 years of construction left so… it could hit $30 billion. At least at Vogtle they are getting two reactors.
We can still categorize a concept, even if the technology doesn’t exist in a useful state yet.
redacted
I’m spooked by the fact that you have no idea how the US enriches uranium, or the difference between a power pressurized water reactor and a fast “breeder” reactor (if you were thinking of plutonium) or a centrifuge.
The US enriches uranium using a gas-centrifuge. The US also no longer recycles spent nuclear fuel, but France does.
redacted
Nuclear plants don’t enrich. Enrichment would happen without power plants. Bomb fuel and power fuel are not the same.
Too bad the energy companies essentially never dispose of the waste properly, because it’s too expensive if they want to give the huge bonuses to their CEOs and buyback thie stock. Even when doing it “properly” it’s basically just making it the problem of future generations once the concrete cracks.
And to reprocess the waste and make it actually safe energy would mean no profit at all plus the tech doesn’t exist yet to actually build the reactors to reprocess the waste. I mean we understand the theory, but it would take at least a decade to engineer and build a prototype.
Compare that to investing in battery tech which would have far reaching benefits. And combining that with renewables is much more profitable.
Too bad the energy companies essentially never dispose of the waste properly
To be fair, nuclear waste tends to be disposed of much more properly than coal waste.
There’s also orders of magnitudes less.
True, but still not anywhere near “clean” as it’s always marketed as.
This is a stupid take.
Coal power puts out more radioactive waste than nuclear does, and coal sends it right into the air where we can’t manage it.
Nuclear waste is kept solid, and contained. We know exactly where it goes and as long as the rules are followed it’s not at risk of polluting anything.
Sure solar and wind don’t have any by product once they are setup, but they also don’t fit the baseline power need that nuclear does.
Problem is it’s not profitable to follow the rules, and conservatives have blocked building a national “permanent” storage site for decades. The IS has no where to put it. It’s just sitting in storage facilities, above ground and in many states in places where an earthquake could cause it to leak into ground water and make the area unlivable for centuries, or cost trillions to clean up.

Quite a large number of Republicans, including Trump himself, spend decades trying to ram Yucca mountain through. It faced heavy resistance from both the Clinton and Obama Administrations, the State of Nevada, and myriad of environmental organizations. Trying to blame it on “Conservatives” is pretty ridiculous.
https://www.ktnv.com/news/history-of-yucca-mountain-1982-2018
Yucca Mountain was killed by decades of persistent interference by opponents of nuclear power.
Yucca Mountain was a bad site. Once they started digging they found that the ground was too loose. It wouldn’t be able to support the weight without sinking. Have you ever seen the foundation of a house that sank on one side? The concrete buckles as the weight of the house slowly compacts the soil. The same thing will happen with millions of tons of waste, steel, and concrete. It’s why missile silos were built in bedrock, not loose soil. Not to mention the technology wasn’t going to allow digging deep enough to store all that much. It would mostly be used for waste from nuclear weapons, ship reactors, and other military projects. Not really that much space would have been available for commercial power generator use.
The conservatives who pushed for it did it because the contractors paid them to. It was blocked because the waste would leak not in thousands of years but in maybe decades. Not to mention the land was stolen from Native Americans and they didn’t want nuclear waste in their stollen land. Among many other issues.
Edit: besides the Clintons have always been conservatives, too. So they’re in that bucket. They’re just moderates.
What makes you say that. Nuclear waste has the consistency of glass or sand depending on how it’s processed. And if we reprocessed that waste like the French we could effectively remove the danger of it.
See earlier in the thread. The waste is highly radioactive, of course, and very hot for some time. First it is dumped in pools. If the pool floods or cracks, you end up with the Fukushima issue. Fortunately that went to the ocean primarily and so was diluted. But in the US, much of the country is landlocked and it would instead enter ground water.
Second, once the material is cooled enough to transport, it is supposed to be moved to a secure location, dropped deep into the ground, and encased in concrete. At this point if there are no earthquakes and water doesn’t enter and damage the concrete, this will stay put for a thousand years or so, but eventually it will get out long before it’s safe considering some of it takes around 250,000 years for it to decay enough to be safe.
As for what France does, as I mentioned, the US has not developed or built that tech because there is ultimately no profit in it and the US is unwilling to spend tax money on it. So it would fall to increased energy cost for the consumer in places where nuclear is used, and no one is going to like that. The cost of building the reprocessing facilities and doing the actual processing outweighs the value of the produced product. And building the first one is going to be the most expensive, and no modern energy company is likely to want to take the hit to short term stock prices in order to take it on. And conservatives won’t approve tax increases at all in the current political climate. And progressive places have already started moving to renewables instead since it’s cheaper.
Not a single power source we have is clean
How is solar, wind, or hydro not “clean”? The generating of the power, not the building of the facilities, building anything is never clean.
People count material, fuel and ecological with nuclear as well, so why not count it with hydro, wind and solar? Concrete is concrete.
Because all technology will require that. If we want energy, we have to build stuff. But there’s no fuel to buy, generally much less ecological impact due to limited waste products since no fuel is being “burned”. And the building cost is one time and generally subsidized, and maintenance is considerably lower, not to mention labor since you don’t need nuclear specialists to run the day to day.

Oh wow really? Hope it kicks off some good news for other plants in the future.
The good news - it’s online, generating clean power, and hopefully demonstrating the safety and benefits of modern nuclear plants.
The bad news - it’s $17B over budget (+120%) and 7 years behind schedule (+100%). Those kind of overages aren’t super promising for investors, but perhaps there are enough lessons learned on this one that will help the next one sail a little smoother.
Either way, good to see it can still be done in the US.
What’s the normal amount of over budget and behind schedule?
Ideally zero? But given this is the first US reactor in decades, it is by definition normal I suppose.
That would be ideal, but people always underestimate the cost and difficulty of things.
Those amounts there. For comparison for example another recent plant Olkiluoto 3 in Finland was 13 years late on a 5 year original construction timeline (18 years total construction time) and
108 billion euros over budget on original budget of 3 billion euros. (Final estimate it cost constructor13-1411 billion euros to build. Technically its fixed price contract so customer price is still 3 billion. However it did bankrupt the builder Areva and litigations are ongoing about, if the French can extract more money from he customer TVO)So doubling the price budget and doubling the build time is not at all unreasonable first estimate on the announced numbers of the builder and customers at start of project.
Also, according to the story, power costs will go up as a result of this reactor coming online.
True, BUT the cost increase was relatively small (~$3.50/mo) - can’t speak for everyone as I know people’s budgets can be quite tight right now, but that’s a price I’d be willing to pay for more nuclear on my grid.
I wouldn’t call it “clean power”. We still don’t have a good solution for the nuclear waste.
Edit: Downvotes because I am not religiously defending a technology and pointing out that there are downsides (EVERYTHING HAS DOWNSIDES!). Too many people from reddit here already.
In finland we have this big hole that goes half a kilometer into stable bedrock. The storage solution is engineered to withstand the next ice age.
It’s Finland, haven’t you been in an ice age for the last 1000 years?
I guess this is a joke, but regardless. The current climate is quite different from having an ice sheet 3km thick on the ground. This summer we were nearing 30°C/85°F on some days.
Compared to the downsides of virtually every alternative energy source, the downsides of nuclear are peanuts.
Sure we do, put it in the holes we took the other stuff out of. Soon our whole planet will be nuclear powered.
Nuclear power plant waste doesn’t significantly contribute to climate change or pollution? So it’s “clean” by most metrics.
Nuclear waste can generally be stored on-site without issue. Reprocessing would be nice, but not even necessary. Just because you don’t understand the problem, doesn’t mean others are “religiously defending a technology.”
Coal was also considered clean in the beginning because they didn’t have to sacrifice forests anymore.
We may not consider the waste a problem now, but that may very well look differently in 50 or 100 years.
Again: I am completely fine considering nuclear power as one of the best options we have. I am not so fine pretending it’s without tradeoffs, because that would ignore how any other form of energy generation in the past/ever finally turned out.
Coal was also considered clean in the beginning because they didn’t have to sacrifice forests anymore.
False analogy fallacy
We may not consider the waste a problem now, but that may very well look differently in 50 or 100 years.
Argument from ignorance fallacy
I am not so fine pretending it’s without tradeoffs
No one is saying it’s free energy or perfect energy. I myself would argue it’s clean and solves some of our current energy problems, while renewables still can’t. Unfortunately it suffers from a bad reputation and misinformation.

The plan, called Cigéo, would involve placing the waste 500 metres (1,640 ft) below ground in a clay formation in eastern France.
Construction is expected in 2027 if it gets approval. Among those opposed to it are residents of the nearby village of Bure and anti-nuclear campaigners.
Burrying waste is not exactly clean. Yes, they reduce the waste. But they are also hitting limits and have challenges in increasing capacities.
In spite of the war in Ukraine, which has made many in the West avoid doing business with Russia, EDF is expected to resume sending uranium to Russia this year as the only country able to process it. It declined to confirm to Reuters it would do so.
That is also not really cool. I also find it a bit shady that something is only doable in Russia. That sounds a bit like it’s only possible there, because they ignore safety rules any other country would have in place and we don’t care because “now it’s their problem”.

But we don’t have that solution yet (see above). That’s like hanging on the idea of having nuclear fusion available. Yes, theoretically nice, but until they are practical, we shouldn’t count on it.
Yes, theoretically the “waste” of current reactors still has energy to be harvested. But practically we can’t use them to a degree where there is no waste afterwards.
For the past decades and sitll ongoing, fission reactors are not clean (also decomissioning them leaves a lot of unusable waste; and they have to be decomissioned at some point).
Also from what I know, extracting the nuclear material from the earth and preparing it for use in a fission reactor is not very environmentally friendly either.
Is nuclear better than coal? Very likely. But it’s not clean.
Reprocessing already exists and it’s been done for decades. I can’t imagine reprocessing fuel for recycling the usable components is that compelling in the US and it would be more geared to waste reduction. 99% of spent fuel by mass could be reused or otherwise treated differently for disposal as it’s radioactivity is much much smaller than the portion that has been transmuted during power production.
Every atom has energy in it, regardless of whether it is radioactive or not. Radioactiveness just makes it relatively easy to extract that energy. But even then, it’s not that simple, not every radioactive material is good for a nuclear reactor. If the fuel absorbs too many neutrons without fission, or produces elements that do, then it can become poison for the reactor. And if it, or the elements it produces, emit very few delayed neutrons and very quickly then it makes it harder to keep the reactor in a sub-critical state (i.e. it makes it harder to not make it explore). Often for these reasons you can’t fully use reprocessed fuel, and instead you have to mix it in low percentages with normal fuel. Reprocessed fuel is also harder (thus cost more) to produce since you have to work with highly radioactive materials.
Yes, we do. Burying it works just fine.
That’s not a solution. That’s a workaround.
And why is that exactly? Decay means the problem will solve itself, all we need to do is keep the waste away from the outside world until then.
This would be a great solution if nuclear waste was a one-time non-reoccurring problem. More waste will be produced continually, and if more nuclear power plants are built to match energy demand, a lot more waste, multiple times more. Eventually we will run out of places to put it, and then of course also deal with the fact that every abandoned old mine or cave in the world is full of radioactive material.
The closest “bury it in a hole” can come to a permanent solution is if the hole is on the moon or something. Even then there are downsides. Do you know how expensive it is to dig giant holes?
You are vastly overestimating the amount of waste a reactor produces. Look up some figures on the internet. There is no way we will ever run out of space to put it.
Yeah, this is one of those topics where any mention of the downside of storing spent fuel safely for 50-100,000 years gets you bombed on. Just like reddit.
Let it run 5 months and the money is back in.
Not really. All costs considered, nuclear is one of the most expensive energy sources.
Darn all those superfluous safety regulations. If only we could make them cheap and fast and not worry about radioactive contamination like the coal industry.
Seriously though, start enforcing adequate regulation on the other sources of life threatening power generation and watch the costs even out.
Yes nuclear power plants are very expensive. But the energy density is phenomenal.
Energetic armortisation is far quicker on a nuclear plant than on solar panels.
And the argument of subsidies is usually a fake one, since governments also pour millions into renewable energies.
Broken down to lifetime cost to the cost of comparable technologies, nuclear is still on the same level as solar and wind.
Since I am from Germany, and German sources might not be ideal to share, let me explain it this way: People are not stupid. They will never choose the financially unwise option, if the other one would seriously be the better one.
People are not stupid. They will never choose the financially unwise option
I see you’ve never been to the U.S.
Ok. Valid argument.
But while Germany quit nuclear power, the rest reinforced their standpoint.
Thousands of scientists from different countries all agreed upon nuclear power to be a reasonable source of energy. Even a Japan is still going forward with nuclear power. It is only Germany, which made an emotional choice, Merkel wanted to please the masses. And here we are now. Burning coal, as if we were thrown back into the industrial time, forced to use primitive methods to produce energy.
People do often act stupid, but you are seeing it from what I consider to be an incomplete perspective. Nuclear could be financially unwise overall, but someone would still get a payday. That 17B over budget wasn’t burned and unmade, it went into the pockets of the people organizing and building the power plant.
All this to say, the huge majority of the people involved in making the power plant a reality weren’t motivated by the efficiency of the power production on a cost basis. Most of them were probably making more money while it was still being subsidized, planned, and built. And while I think subsidies are generally useful and good, they can be a vector of financial abuse when it comes to unprofitable industries.
Lastly “lifetime cost” is a bit of a useless metric when the majority of that lifetime comes too late. No point to a power source that will cleanly produce power after it has meaningfully contributed to pushing us over the edge and past the breaking point for a climate that can support agriculture as we know it. There isn’t enough time or margin for error in emissions left available to build all the nuclear plants needed to meet energy demands.
Yeah, after literally bankrupting Westinghouse and costing us Georgians billions of dollars. I’m all for more nuclear power but this project was a colossal shitshow.
Georgia also has some shiny new solar factories so I’m interested to see how deep into renewables we can get in the next decade.
“If you wish to make a nuclear reactor from scratch, you must first invent the universe”
Inventing the universe is only a small part of it, you have to get regulatory permission first!
(Joking aside, I support regulated nuclear power plants.)
And Apple pie. You need that before you make a nuclear reactor.
Just in time for openheimer in IMAX!
Very good news. Nuclear power simply has way more benefits over fossil fuels. Not to mention it’s statistically safer, despite what decades of anti-nuclear sentiment has taught the public.
I’m all for investing in other forms of energy beyond fossil fuels, this is good news to me.
what does built “from scratch” mean? Just a more emphatic way of saying “built?” Or that it wasn’t repurposed out of some already built building?
Hey wow, it’s great to see we are still persuing this avenue for energy, I hate how stigmatized nuclear became (with some good reasons). Like any technology, we just rushed to using it without understanding the full consequences when shit goes wrong. Hopefully we’re better prepared now.
Wait… is this the USA’s first Gen III+ reactor?
