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.
14 years and 35 billion (combined with #4 which has not been finished) and didn’t generate a single kWh in anger until now. Put the same investment into renewables and it would generate similar or greater energy and would start doing so within a year.
The argument against nuclear now is not about safety. It is about money. Nuclear simply cannot compete without massive subsidies.
Renewables and nuclear are in the same team. It’s true that nuclear requires a greater investment of money and time but the returns are greater than renewables. I recommend checking this video about the economics of nuclear energy.
That video completely ignores decommissioning costs for nuclear power plants and long-term nuclear waste storage costs in its calculation. Only in the levelized cost of electricity comparison does it show that nuclear is by far the most expensive way of generating electricity, and that it simply can’t compete with renewables on cost.
People love to look at nuclear power plants that are up and running and calculate electricity generation costs based just on operating costs - while ignoring construction costs, decommissioning costs, and waste disposal costs.
The cost of storing nuclear waste for a running plant is only a few hundred thousand a year; basically just just salary for a few people to transport it to a big hole in the ground.
Decommissioning costs a few hundred million, which sounds like a lot, but for a project that lasts for decades it’s basically nothing.
You could probably fit all of the nuclear waste America produces in few trucks. It’s not as much as people think.
Or even less if we – gasp, shock, horror! – reprocessed it.
(We don’t do that because of overblown fears about nuclear weapons proliferation.)
Those must be some big fucking trucks. And as far as I know, only Finland has actually developed any long-term storage which could be considered safe.
Nuclear is fine, but nuclear fanboi takes are similar to weed fanbois, it’s not a perfect solution.
You seem to think a big number means a big pile of green goo. But actually…
Estimated total cost of decommissioning in the UK is £120bn. But it’s going to take 100 years to do it… so yay lots of rotting radioactive buildings for the next century.
The nuclear waste storage facility cost 53bn to build, let alone run… so way off your ‘few hundred thousand a year’.
That’s for way more than just one plant, and there’s a lot more going on that resulted in such a high price tag. That isn’t normal.
It’s a reinforced hole in the ground, designed to last a long, long time after humans forget it exists. Of course it cost money to build, but now it’s just there. It doesn’t cost anything for it to continue to exist. Maybe there’s a little security or staff for some purpose, but I don’t know what they would even do.
Does that video talk about how wind turbine blades aren’t recyclable at all so they end up in landfills? Solar panels are 75% recyclable which is excellent but that still means 25% is going into the ground. Nuclear is the only way forward.
That sound like addressable design challenges

Renewables and nuclear play different sports.
Renewables are better for most of our needs but there is a backbone need of base power. Nuclear is an expensive but clean way to provide that.
By my very very very rough calculations, you could build a large scale solar farm with 3x power output and have enough money left over to build a 33GWh battery. That would more than cover a continuous supply of 1GW.
Absolutely, and we should. We should have both. Nuclear has a very long lifespan and very consistent power. Ideal battery setups do to buy long term lithium battery storage is less of a thing, but it’s growing. There are some other battery techs that use other chemistries which are also attractive.
Multiple eggs in multiple baskets.
Not the guy you responded to but I totally agree. Plus I think countries like Canada, with lots of snow and less direct sunlight, would appreciate an energy source they can rely on in the winter
Unless there are a few cloudy days in a row… My panels produce a lot less than normal during cloudy days.
Remember that blanketing the world with solar panels isn’t exactly great for the environment. Rooftops makes a lot of sense, but the cost goes way up, an maintenance becomes a nightmare. The footprint of nuclear is much smaller
The footprint of solar is significant, but still nothing compared to agriculture. E.g. The area used to grow corn to make ethanol in the US is ~ 3x what you’d need to fully power the US on solar.
~96000000 acres used for corn, ~40% of that is used for ethanol. That makes 38.3e6 acres. First estimate I found for area of solar panels to fully power the US on solar alone was 14.08e6. That makes corn for ethanol 2.7 times the area of solar panels if all that was used was solar.
Yeah agriculture isn’t great for the environment either, but that doesn’t actually make solar any better
or we could do both
Also I would like to see the enviromental impact of building your 33GWh battery.
What price per kw generation are you using?
France was able to output 2 reactors per year at 1,5 billion of euros per 1000MW for more than 2 decades during the 70’s to 90’s. The whole French nuclear industry has cost around 130-150 billions between 1960 and 2010, including researches, build and maintenance of France’s whole nuclear fleet.
A 1000MW reactor, at current French electricity price and for a 80% capacity factor, generates 1,4 billion of euros worth of electricity per year, for a minimum of 60 years.
Nuclear is not costly, and can absolutely compete by itself, if you don’t sabotage it and plan it right.
Except those reactors are off 30-50% of the time due to shoddy construction, €1.5/W in 2023 money is pure fiction, and overnight costs with free capital aren’t real costs once you adjust for inflation and stop cherry picking the first reactors before negative learning rates kicked in.
I would be very interested to know why the trend has moved away from building reactors in time and within a reasonable budget. It seems that most projects after the turn of the millennium haven’t been cost effective.
Why did we manage to build reactors well before but not now?
Base load my friend. We also need steady, reliable, clean power when it’s dark and calm. Until we can accomplish seasonal grid storage of renewables, this is the less expensive option.
There are plenty of firming options (battery, pumped hydro, flywheels etc) which deliver reliability for a fraction of the price of this boondoggle. Not to mention a diverse portfolio of renewable technologies spread over a large geographical area is actually quite stable. When the sun isn’t shining in one area, the wind may be blowing or the sun shining in another area.
Those can only hold enough power for minutes or hours.
We need to be able to store power from the summer until the winter. Months. We need to store energy from when the sun is shining in July until it’s not in December.
The only possible way to do that now is to store it as hydrogen or hydrocarbons. That infrastructure is currently very lossy, expensive, and only hypothetical.
This idea they can only hold for minutes or hours is simply not true not to mention the entire premise is false. Only the cloudiest of days the solar panels produce 20% what they do on the sunniest days that means you only need to build out 5 times the expected output to always be able to produce what you need during sunny hourse. That means you only need to have battery backup for 16 hours. Something that’s completely feasible. The idea batteries can’t hold power for months isn’t true it’s that it’s not currently economical. How long do you think your electronics take to get from the plant to the store till you buy it and turn it on. If we’re talking about cost then let’s look at this plant. 1.1GW nuclear reactor costs 35 billion and 15 years. A solar farm built out to 5 times capacity would cost roughly 6 billion. Now triple that for battery costs if you want 24/7 electricity were on the order of 18 billion. That’s nearly half the cost and this is being very conservative assuming you want this to be a baseload supplier but will output way more most of the time. Now you will have nearly free electricity during most of the year that other industries could take advantage of like aluminum processing or something like that.
You are simply incorrect. I don’t know why you think that there are any actual technologies that can store terawatt hours of electricity for months at a time. You can’t pump storage the entirety of lake Mead. You can’t have flywheels that have such low friction at such high mass and speed. And the batteries…you can’t be serious.
You are also under the incredible misapprehension that the market is going to build excess capacity such that they will need to give away “nearly free” electricity. The need to be able to store it to sell when the price is better or be funded for some kind of (as yet hypothetical) carbon sequestration project.
Being generous with a 16h battery you already spend half overnight. What would happen in your scenario if it’s cloudy for longer than 8 hours? If it wouldn’t even last for a day it’s not a realistic plan that accounts for normal weather
You don’t need power storage for months, if you combine different renewable sources and have power lines connecting different areas. Wind and solar complement each other usually.
You need to be able to bridge a few weeks though, because there will be gaps, but you don’t need to store solar power for half a year to make it. It is still a big issue, but no need to exaggerate.
There’s also a reliability element too. Nuclear can reliably output a given amount of energy, at the cost of being slow to alter. Many renewable sources have sporadic amounts of power throughout each day. Either is better than fossil fuels at least.
Good point but that is not insurmountable. There are many ways to achieve predictability (batteries, hydro, tidal) that also come on stream much quicker than any nuclear plant.
Ah I’d not consider these! That gives some hope too then :) I hope we get the battery advances we need asap, the urgency from the climate crisis is strong lately.
Nuclear isn’t entirely reliable though. During the big heatwave last year at least 1 and iirc at leat a few French reactors had to be shut down because the water levels in the rivers they were on were not high enough to get sufficient water to cool them. Which is a problem that’s only going to get worse as climate change progresses.
That’s a limitation of the secondary power conversion side and is true for any power generation methodology that relies on steam generation. That said, there’s alternatives to the traditional Rankine cycle that could be deployed without modifying the nuclear side of the plant.
I don’t recall them being shut down (that would be a drastic step). They were forced to reduce output, though (making the energy more expensive).
there are a bunch of new reactor designs that don’t use water.
The issue is that right now renewables energy don’t reduce CO2 emissions by much. (Except for hydro)
Sure if we look at the energy produced it’s very clean. The issue is intermittence. As a society we decided to continue using electrical equipment even when the sun is not shining and the wind is not blowing. So we use fossil fuel to compensate and overall the electricity production still enjoy a lot of CO2. We could use batteries, but utility scale battery are not very developed yet.
Same issue with the price. Sure solar energy is very cheap, when it’s sunny. But what if I want to turn on the light at night ? The solar panel are not producing, the wind is not blowing, price is irrelevant if I can’t get power when I need it.
Nuclear can produce a reliable amount of energy all the time.
I hope we will see the development of utility scale energy storage because this is what we really need for the development of renewable energy.
We don’t necessarily have to use batteries. In mountainous regions we already have stations that use surplus power to pump water up a mountain and then drop it down to generate energy when needed. Its basically a potential energy battery. But this is usually location limited and more expensive to set up.
Yes, Pump Storage Hydroelectricity is a great option for storage. It’s not the most efficient but it allows to store massive amount of energy.
I think today it’s the main utility scale storage solution in the world.
There’s also compressed air and flywheels for energy storage.
You’re describing dams, and basically all the good locations are taken already.
No, he’s describing a pumped storage facility.
Tbf that would be two dams and they did use the plural of dams, technically ‘dams’ could be a pumped storage facility.
To be even fairer, his central point that “all the good locations are taken already” only applies specifically to the regular type of dams that don’t use pumped storage. For traditional hydroelectricity you need an easily-dammed-off hilly basin containing a large/high hydraulic head river, but for pumped-storage you just need the hilly basin.
To be even fairerer, the body of water that gets pumped doesn’t need to be dammed; if you have a steady enough river, you can suck the water right out of the side of it. Also, the basin isn’t a prerequisite, you could build holding tanks at the top of a hill.
Hell, you could enclose the whole thing to control evaporation and use the same water over and over, no natural body of water necessary. Better yet, use a denser fluid to achieve the same result in a smaller space. You could probably fit the whole thing in a single building.
And a lot of that can simply be solved with a larger grid.
Yes, in a small geographic area, you might run into a situation where the sun isn’t shining and the wind isn’t blowing. On the other hand, on a global scale, the sun is always shining and the wind is always blowing.
A realistic solution right now are therefore continent-wide grids that combine hydro, solar, wind and pumped hydro storage.
Copied my comment above, sorry for the double wall of text:
Let’s play around with the thought of powering all of America with renewables. America’s coal, gas, petroleum and nuclear plants generate a combined baseload power of 405 GWavg, or “gigawatts average.” (Remember, a gigawatt is a thousand megawatts.) Let’s replace all of them with a 50 / 50 mix of onshore wind and CSP (solar), and since our energy needs are constantly growing, let’s round up the total to 500 GWs, which is likely what we’ll need by the time we finish. Some folks say that we should level off or reduce our consumption by conserving and using more efficient devices, which is true in principle. But in practice, human nature is such that whatever energy we save, we just gobble up with more gadgets. So we’d better figure on 500 GWs.
To generate this much energy with 1,000 of our 500 MW renewables farms, we’ll put 500 wind farms in the Midwest (and hope the wind patterns don’t change…) and we’ll put 500 CSP farms in the southwest deserts—all of it on free federal land and hooked into the grid. Aside from whatever branch transmission lines we’ll need (which will be chump change), here’s the lowdown:
Powering the U.S. with 500 wind and 500 CSP farms, at 500 MWavg apiece.
35,135 sq. miles (169 mi / side)
(the size of Indiana)
60-year cost ……… $29.25 Trillion
That’s 29 times the 2014 discretionary federal budget.
If we can convince the wind lobby that they’re outclassed by CSP, we could do the entire project for a lot less, and put the whole enchilada in the desert:
Powering the U.S. with 1,000 CSP farms, producing 500 MWavg apiece.
24,234 sq. miles (105.8 mi / side)
(the size of West Virginia)
60-year cost ……. $18.45 Trillion
#That’s to 18 times the 2014 federal budget.
Or, we could power the U.S. with 500 AP-1000 reactors.
Rated at 1,117 MWp, and with a reactor’s typical uptime of 90%, an AP-1000 will deliver 1,005 MWav. Five hundred APs will produce 502.5 GWav, replacing all existing U.S. electrical power plants, including our aging fleet of reactors.
The AP-1000 uses 5,800 tonnes of steel, 90,000 tonnes of concrete, with a combined carbon karma of 115,000 t of CO2 that can be paid down in less than 5 days. The entire plant requires 0.04km2, a patch of land just 200 meters on a side, next to an ample body of water for cooling. (Remember, it’s a Gen-3+ reactor. Most Gen-4 reactors won’t need external cooling.) Here’s the digits:
1.95 sq. miles (1.39 miles / side)
(1.5 times the size of Central Park)
60-year cost ……… $2.94 Trillion
#That’s 2.9 times the 2014 federal budget.
Small Modular Reactors may cost a quarter or half again as much, but the buy-in is significantly less, the build-out is much faster (picture jetliners rolling off the assembly line), the resources and CO2 are just as minuscule, and they can be more widely distributed, ensuring the resiliency of the grid with multiple nodes.
And this is without even mentioning MSRs.
Was this project a complete shitshow of sheldon before seen-proportions?
Yes.
Does this mean that we should make the move towards powering the US from 100% renewables instead?
Well if you hate math and logic enough to even consider it, sure. Go ahead.
Yea you’re right.
People make stupid arguments about base load (nuclear doesn’t match supply demand so it’s meaningless argument) or renewables only being built out for maximum output = highest demand (in reality you need to build minimum output as a function of highest demand. Highest total power will far exceed highest demand and still be cheaper than fossil or nuclear. But people can’t grasp that).
Finally. Huge interconnectors like what China and Europe are doing/ done never come up.
It’s just the same old. We built 10% of renewables we need yet we are still using gas. Proof renewables don’t work!
That’s not really accurate. There are endless lawsuits when it comes to getting windfarms going because people claim it will ruin their view or the rare redheaded blue-eyed pigeon will be hurt or some other bogus nonsense. These lawsuits can go on and on for ages.

Wind and Solar struggle greatly with “not in my backyard”. Of course, so too with Nuclear, and even more extreme with Nuclear, but you are correct that solar and wind have challenges with getting going.
These days EVERYTHING has like 10 lawsuits attached to it before anything can happen. Then we wonder why everything is always at a stand-still. We had a local brwery and pub in a perfect location get sued because the restuarant next door (which is kind of run down) was afraid of the competition. Now the Brewery is actually considering pulling out. Such BS especially the influx of people coming to the area would probably end up helping both businesses.
The nuclear lobby kids never seem to accept going renewable over nuclear as a possible reality. They refused to acknowledge it in the online circles of the mid to late 90s on News Groups, early 00s on Slashdot, didn’t want to see it in the 00s on Digg, attacked any questioning nuclear the 10s and early 20s on reddit. It has been a consistent online turf protection war in comment sections for decades.
Every nuclear post turns into a circle jerk and a handful of people trying to ‘in before renewables’ to make sure to drown out anything that isn’t waving the nuclear flag with little reservation.
We need both in some respects to maintain current electrical needs, but money and time to deploy is quantifiably much more efficient with renewables in practice vs nuclear on paper. Having a much larger renewable system spread all across the country would be of a greater short and long term benefit. Solar on every home, a small solar cell on every light pole along with low wattage monitoring systems for power distribution optimization, large desert solar installations, agrivoltaic farming (if it’s not just bullshit), wind farms in strategic areas with low impact to birds, etc.
Doing all those things would cost hundreds of times what it costs to build a reactor. There are reactors already engineered and that exist elsewhere in the world capable of powering entire cities for over a hundred years that are easily decomissionable unlike the older 1970s reactors that we have. Also renewables are unable to produce power on demand when load demands spike suddenly. U need fossil fuel for that currently. Not to mention the process of creating solar panels is one of the most environmentally damaging manufacture processes and the only country that possesses the materials to make them is China… Oil receives metric assloads of government subsidy. Why should nuclear not get the same? Nuclear power is the only thing we know of that has rhw ability to fill all of the functions that fossil fuel power plants have.Idf theres actually other options then cool but iv looked at every alternate energy source and rhw big thing that sticks out is a couple things. If the weather gets too cold, or too hot, theres a natural disaster or other condition that necessitates a very sudden and high increase in kilowatt hour demand renewable energy sources buckle. And then your left having to fire coal to meet the energy need.
Nuclear is a waste of time and money.
Yeah, well, that’s just like, your opinion, man
His username checks out!
That said, you might share his opinion if you were a Georgia Power ratepayer who’s been paying extra on their power bill for years and years now even though it’s only now just come online (and while the Georgia Public Service Commission has allowed the high profit margins for Georgia Power stockholders to be maintained even despite all the cost overruns).
