The global average to build one is ~7 years. People have been saying they take too long to build as an excuse for not building them for what, two decades or more? It seems to be taking longer to not build them than to build them.
> By the time a new plant is ready, alternate sources (likely solar + battery and long-distance HVDC) will have eaten its lunch.
Neither of those have the same purpose. Solar + battery lets you generate power with solar at noon and then use it after sunset. It doesn't let you generate power with solar in July and then use it in January. More than a third of US energy consumption is for heating which is a terrible match for solar because the demand is nearly the exact inverse of solar's generation profile both in terms of time of day and seasonally.
HVDC is pretty overrated in general. It does nothing for the seasonal problem and it's expensive for something that only provides a significant benefit a small minority of the time, i.e. the two days out of the year when the entire local grid has a shortage but a far away one has a surplus. It's also hard to secure because it inherently spans long distances so you can't have anything like a containment building around it and you end up with an infrastructure where multiple GW of grid capacity is susceptible to accidental or purposeful disruption by any idiot with a shovel or a mylar balloon.
That’s not necessary. Solar panels are so cheap that you can massively overprovision for winter and still come out ahead of nuclear.
I don't doubt that that resulting number is still very low, or there (being intentionally optimistic about politics and society here) wouldn't be any nuclear plants.
Especially long-term storage is tricky, and if you need to consider time horizons of millenia, even small risks add up.
> Significantly more people have died installing solar panels by falling off of roofs.
In fairness, you then also have to consider "regular" industrial accidents at nuclear plants, which are probably still much lower (due to the presumably much higher energy output per employee hour than other forms). But that's besides the larger point of low probability and historical risk.
The difference between renewables and nuclear power is who gets harmed.
When dealing with nuclear accidents entire populations are forced into life changing evacuations, if all goes well.
For renewables the only harm that comes are for the people who has chosen to work in the industry. And the workplace hazards are the same as any other industry working with heavy things and electric equipment.
The worst nuclear accident involving a nuclear plant (Chernobyl, which occurred in a country without regulation for all intent and purpose) killed less people than the food processing industry cause every year (and I'm not counting long term health effect of junk food, just contamination incidents in the processing units leading to deadly intoxications of consumers).
In countries with regulations there's been 2 “major accidents”: TMI killed no one, Fukushima killed 1 guy and injured 24, in the plant itself. In any industries that would be considered workplace safety violation, not “major accident”… And it occurred in the middle of, and because, a tsunami which killed 19000!
I'm actually happy this regulation exist because that's why there ate so little accidents, but claiming that it's still hazardous despite the regulations is preposterous.
The chernobyl was poisoning Russian soldiers by the start of Ukrainian invasion when they were dumb enough to sleep there.
If we only tolerated the same long term risk level for food, you wouldn't be be eating anything but organic vegetables. The fact that we put a sarcophagus to prevent material from leaking is just the reflection of the accepted limits. Flint water crisis was much more dangerous than leaving Chernobyl without the latest sarcophagus but nobody cared for a decade.
> The chernobyl was poisoning Russian soldiers by the start of Ukrainian invasion
The stories of acute radiation poisoning have been debunked repeatedly, there simply isn't enough radioactive material left there to cause such symptoms (it's still a very bad idea to eat mushrooms or the meat of wild animals living there, you'd risk long term cancer, but nothing close to acute radiation poisoning, it's simply not possible from a physics standpoint).
And again, we're talking about an accident that happened in Soviet Union on a reactor absolutely not designed with safety in mind and with a Soviet party member who threatened the engineers into bypassing safety mechanism in order to operate outside of the design domain of the plant. And the resulting accident was nowhere near close to the Bhopal catastrophe.
Chemical site have deadly accidents every other years and nobody seems to care but they'll obsess about nuclear ones even when they barely kill anyone. And chemical plants accident do leave long lasting pollution with durable health effect, but we don't permanently evacuate the places because we tolerate the risk.
The Hinckley Point C EPR reactor would have produced electricity at a rate below £20/MWh instead of a planned £80/MWh if it was financed by government bonds.
You can finance the competition in the same way and get similarly cheaper prices.
Hinkley Point C just got a loan at a 7% interest rate to finish the plant. That is after about all uncertainty should already have been discovered.
Now add making a profit and factor in the risk on top and you’ll end up with electricity costing $400 per MWh
Exactly what "storage" means there is the key, especially at high latitude. Do not assume just batteries.
My state (NSW, Australia) for example uses no less then 6 GW at all times of day. Variable load is on top of that during the day.
If we had 6GW of nuclear plants, our grid would be almost completely green and they'd run at 100% utilization.
You’ll end up at $400 per MWh excluding transmissions costs, taxes etc.
Your state already has coal plants forced to become peakers or be decommissioned because no one wants their expensive electricity during the daytime. Let alone a horrifyingly expensive new built nuclear plant.

You can't quickly change the amount of power it generates. Which is what you need if you want to use it together with dirt cheap solar.
It's very expensive. In fact, noone knows how expensive it will end up being after a couple thousand of years.
It's dangerous. For millenia. Vulnerable to terrorism. Enabler of nuclear weapons.
It takes a long time to build and bring online.
It doesn't scale down.
Finally, Kasachstan is the major producer of Uranium. Yay?
You always need something in the grid that can change the amount of power it generates regardless of what you use in combination with it, because the demand from the grid isn't fixed. All grids need something in the nature of storage/hydro or peaker plants.
The advantage of combining solar with nuclear is that their generation profiles are different. Nuclear can generate power at night and doesn't have lower output during the peak seasonal demand period for heating. Nuclear is baseload; it doesn't make sense to have more of it than the minimum load on the grid, but no one is really proposing to. The minimum load is generally around half of the maximum load.
> It's very expensive. In fact, noone knows how expensive it will end up being after a couple thousand of years.
If you actually reprocess the fuel there is no "couple thousand of years". If you instead put it in a dry hole in the desert, you have a desert where nobody wanted to live to begin with that now has a box of hot rocks sealed in it. It's not clear how this is supposed to cost an unforeseeable amount of money.
> Vulnerable to terrorism.
Nuclear plants are kind of a hard target. The stuff inside them isn't any more of a biohazard than what's in a thousand other chemical/industrial plants that aren't surrounded in thick concrete.
> Enabler of nuclear weapons.
The US already has nuclear weapons and would continue to do so regardless of how much electricity is generated from what sources. The argument against building nuclear reactors in Iran is not an argument against building nuclear reactors in Ohio.
> It takes a long time to build and bring online.
Better get started then.
> It doesn't scale down.
Decent argument for not having one in your house; not a great argument for not having one in your state.
> Finally, Kasachstan is the major producer of Uranium. Yay?
The country with the largest uranium reserves is Australia. Kazakhstan is #2 and has about the same amount as Canada. Other countries with significant reserves include Russia, India, Brazil, China, Ukraine and several countries in Africa. The US has some itself and plenty of other places to source it. It can also be extracted from seawater.
The US is also in the top 4 for thorium reserves with about 70% as much as the #1 (which is India), and thorium is 3-4 times more abundant overall than uranium.

> Partitioning and recycling of uranium, plutonium, and minor actinide content of used nuclear fuel can dramatically reduce this number to around 300 years.
Let's not pretend like the track record of energy production is free of externalities.
We CAN also produce almost all of our plastics from recycled ones. We don't, because those are more expensive than new.
You need solar. Make hydro the backup, fill reservoirs as your reserve and sell extra energy when they're nearly full.

It uses enormous amounts of land and capital to build, and is ongoingly dangerous in a unique way. If LiFePO4 can do 4 hours at full output already, and be placed anywhere using volume manufacturing to expand, then batteries are straight up better.
Pumped hydro is an expensive dead end.
"Base load" is just some nonsense from nuclear fans to get the cost per GWh down.
