Where we lost decades of progress was governments pouring enormous amounts of R&D money into nuclear instead of renewables. We got a nuclear a head start that turned out to be a dead end. We could have gotten solar, wind and storage cost competitive with fossils decades earlier. And as a side effect kept the west competitive in energy tech.

Yeah, nuclear is fine. It just at this point it can’t really compete with solar+battery for how quickly you can bring things online. The 10 or 15 years required to build a nuclear plant is pretty devastating for it when you can build up solar in 1-2 years instead.

It also can't compete on cost. Nuclear is crazy expensive and prone to cost overruns, so no market party is willing to build it without the government taking on all of the financial risks. And with the rapidly evolving power landscape the long payback time only makes things worse.

That's the most depressing thing. Nuclear has been successfuly overregulated.
reply
It’s not even that it’s overregulated but that the amount of power it brings online at a time is just too big.

Individual wind turbines aren’t very big, solar panels get laughably small, and while they are not efficient at their small form factors they are very easy to scale up and down. Nuclear is the exact opposite, representing a very large single point of failure, and even under pre-renewables hard to absorb; some of the first pumped hydro was developed to take excess nuclear capacity because it cannot scale up or down very easily.

Its not just matter of regulation if it was that easy to build China would be building 100s. And by saying China I am referencing their manufacturing capacity and them being a command economy that does not have the same financial profitability concerns. It is not like they have not tried they have but nuclear technology the world has currently have does not translate to mass manufacturing.
reply
China is currently building almost 40 nuclear plants at the same time.

And we've sunk decades into small modular reactors and it hasn't born much fruit either.

If you deregulated it and made it pay for its own disaster insurance it would stop existing.

Without price anderson act dumping the liability on to taxpayers nobody would build nuclear reactors even at the cost they are.

A completely predictable outcome of being under regulated and having several disastrous outcomes.

Unfortunate, but that's the way the cookie crumbles.

reply
It's not a shame it stagnated. It's good that it stagnated, since it wasn't competitive.

It's a shame it wasn't competitive.

reply
What do you think I mean by "stagnated"?

Nuclear isn't uncompetitive due to some inherent technological reason. It's uncompetitive due to overregulation and gold plating.

Solar used to be completely uncompetitive, but improvements in technology and increases in scale made the economics work. Nuclear got kneecapped before that could have a chance of happening.

reply
> It's uncompetitive due to overregulation and gold plating.

This is an oft repeated point by pro nuclear folk, but it’s not true. There are many regulatory regimes all over the world, and new nuclear is competitive in effectively none of them. Even in single party state china with few regulations , nukes are a declining share of total power every year.

They’re just giant big complex pieces of machinery. With huge ongoing security, insurance and deferred decommissioning costs.

Compare the average specific carbon emissions and price per kWh between Germany and France and tell me nuclear is not competitive.

Nuclear is so competitive that they had to ban it in Germany to get rid of it.

reply
You're reading from the playbook of bad nuclear bro arguments.

The implication you're trying to draw there is a non sequitur. That situation doesn't contradict what I said. Moreover, France is going to be dragged kicking and screaming into the renewable age because they can't afford to subsidize nuclear builds enough to make a nuclear approach work.
