We need to drive down the costs of implementing nuclear energy. Most of it are fake costs due to regulation. I understand that regulation is needed but we also need nuclear energy, we have to find a streamlined way to get more plants up and running as soon as possible. I think they should all be government projects so that private companies can't complain that they're losing money and keep have to ratchet up the prices, like PG&E in California. My rates have doubled in a few years to over $0.40/kWh and up over $0.50/kWh after I go up a tier depending on usage.

It’s really not, nuclear inherently requires extreme costs to operate. Compare costs vs coal which isn’t cost competitive these days. Nuclear inherently need a lot more effort refining fuel as you can’t just dig a shovel full of ore and burn it. Even after refining you can’t just dump fuel in, you need fuel assemblies. Nuclear must have a more complicated boiler setup with an extra coolant loop. You need shielding and equipment to move spent fuel and a spent fuel cooling pond. Insurance isn’t cheap when mistakes can cost hundreds of billions. Decommissioning could be a little cheaper with laxer standards, but it’s never going to be cheap. Etc etc.

Worse, all those capital costs mean you’re selling most of your output 24/7 at generally low wholesale spot prices unlike hydro, natural gas, or battery backed solar which can benefit from peak pricing.

That’s not regulations that’s just inherent requirements for the underlying technology. People talk about small modular reactors, but small modular reactors are only making heat they don’t actually drive costs down meaningfully. Similarly the vast majority of regulations come from lessons learned so yea they spend a lot of effort avoiding foreign materials falling into the spent fuel pool, but failing to do so can mean months of downtime and tens of millions in costs so there isn’t some opportunity to save money by avoiding that regulation.

It really is. Nuclear is 100-1000x safer than coal. By insisting on such an aggressive safety target, we force prices up and actually incur much higher levels of mortality - just delivered in the boring old ways of pollution and climate-driven harms.

See https://ourworldindata.org/safest-sources-of-energy for detailed stats.

I think we should target “risk parity with Gas” until climate change is under control.

You are making a common mistake, your source does only considers things that have happened, not things that could happen. But we know what could happen, which is why the security standards have to be high for nuclear power.

A Chernobyl level incident every single year would kill fewer people than the annual number of people that die from fossil fuel particulate emissions. We can imagine reasonable numbers of accidents and still be sure that it would be dramatically safer than fossil fuels, even ignoring climate change.

And the land rendered uninhabitable would represent less land lost than is expected to be lost from sea level rise, most of which will be extremely hi-value coastal areas.

There is no way you can run the numbers where nuclear, even with dramatically reduced safety standards, is not preferable to fossil fuels. By making it so expensive with such heavy regulations, all we have done is forced ourselves to use the worse-in-all-possible ways fuel source for most of a century, causing millions of premature deaths and untold billions in environmental damages.

Over-regulation of nuclear is high up on the list of greatest civilizational blunders humanity has ever made.

This is not true. You are using the lawyers definition of damage from Chernobyl, but the doctor's definition for fossil fuels. Chernobyl was much worse than you believe, but I don't expect to change your mind on that point here.

But why are you arguing as if it's either nuclear power or global warming?

China has added the equivalent of 25 nuclear power plants worth of solar generation yearly for the past couple of years. Not even China is able to build nuclear plants faster than in 5-6 years or so - it takes too many workers, too much resources. It's too little and too slow to make a difference.

Efen if you believe it is safe, Nuclear is clearly a roadblock, or a detour. We should instead build storage and solar, which can add orders of magnitude more power in shorter time.

(But even then we'll have to deal with global warming).

No, I'm not. Pick whatever estimate of deaths from Chernobyl you like. Take the highest, most unreasonable estimate. It's still true. And yes, _now_ we have other options. In 1960 we didn't. We have nearly a century of carbon emissions and particulate deaths that were unnecessary. There are literally _millions_ of premature deaths every year as a result of fossil fuel particulate emissions.

Nuclear may not be the best option anymore (I'm skeptical that an ideal power generation mix doesn't include more nuclear than we currently have, but agree that it probably shouldn't be the primary source anymore), that doesn't change the fact that not using it for past 80+ years as our primary energy generation source was a huge civilizational blunder.

That's the lawyer definition though - because some 50 people sacrificed their lives and because we spent 600 billion euros on remedies during the first 30 years, nobody can prove how bad it might have been.

But scientists will tell you how much caesium and iodine was released per day of that fire burning, the force of the steam explosion that might have been, how close it was to the contaminate the ground water supply and so on.

Then doctors will tell you how that would affect the people living in the fallout areas, and for how long the ground and food supply would be affected.

So if you let go of the lawyer definition, estimates are easily in the double-digit million dead.

Which we risked for a grand total of 28 TWh of electricity produced from Chernobyl.

And that's the bigger point here - even if the risks were way less than they actually are, the payoff is not worth it. Electricity generation causes less than 1/4 of the co2 emissions in the US - road transportation alone is a larger source.

Nuclear is not and never was a solution to global warming. Best case it helps of course, but only until something happens like Fukushima or Chernobyl. The billions spent on those two incidents alone would have had a bigger effect if they were spent subsidizing electric cars, solar panels, battey production and such.
