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 :)
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
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.

Ooh a lot of people here seem very pro-nuclear-power. That’s cool!
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.
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?
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
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.
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.
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.

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.

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.
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.

“If you wish to make a nuclear reactor from scratch, you must first invent the universe”
And Apple pie. You need that before you make a nuclear reactor.
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.
It’s pronounced NOOK-YOU-LERRR
I’m all for investing in other forms of energy beyond fossil fuels, this is good news to me.
Just in time for openheimer in IMAX!
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?
It looks like it!
Looks like the only completed Gen 3 nuclear reactors are in Asia, at Kashiwazaki (Japan), Kori (South Korea), Yangjiang, Fangchenggang, Tianwan (China), and Kudankulam (India).
Edit: I missed the Gen III+ part of that Wikipedia page. The other currently operation or under construction Gen 3+ reactors are in Sanmen, Shidao Bay, Taishan (China), Novovoronezh II, Leningrad II, Kursk (Russia), Akkuyu (Turkey), Rooppur (Bangladesh).
Not sure, this isn’t super easy to research, but an identical reactor is being built along side this one, so if it is our only 3+ it hopefully won’t be for long
Good to see industrial self sufficiency coming back to the US
Outstanding!
This is awesome to see, but I wonder if an array of Small Modular Reactors would be the way to do it in the future. Nuclear is a fantastic and safe source of clean energy, so I hope it can compete better on the economic side.
SMR’s are even worse than the big ones. With no breeding and small, lower temperature steam generators they’d be undsr half as efficient as a traditional LWR. The fuel costs (which will only go up as the easy uranium is tapped out) alone would exceed the current all-in cost of renewables (which are still dropping rapidly).
Ah well, it figures they have a tradeoff like that. Maybe they’ll be limited to remote locations then.
Like so many things, it will come down to cost. It’s fortunate that renewables are getting so much cheaper because we pretty much are betting on them by being so reluctant to expand nuclear. Hopefully batteries and other energy storage technologies keep advancing rapidly.
All thermal generation will cause direct global warming via waste heat if used to excess.
Fossil fuels have an order of magnitude or two more thermal forcing via GHG, so it’s largely irrelevant there, but solar can produce a couple orders of magnitude more energy than the world uses now without significant land use. As such fusion (with the exception of p-B or He3 direct conversion with no steam engine which is a bit more scifi) hits thermal limits before solar hits land limits.
Intuitively you can frame this as “a small fraction of the amount of sunlight that hits the planet is the amount of energy that changes the planet’s temperature” which is basically a tautology.
Vogtle was a massive shitshow of corruption and delays, never thought it would actually be finished. Ironically, the price of electricity is set to go up, so that promise of lower bills has gone out the window.
“Nuclear power - too cheap to meter!!”
I’m still waiting for that to happen.
