I think a good exercise for the reader is to reflect on why they were ever against nuclear power in the first place. Nuclear power was always the greenest, most climate friendly, safest, cheapest (save for what we do to ourselves), most energy dense, most long lasting, option.

I disagree with cheapest. If you factor in twenty years build time and nuclear waste disposal, the whole thing is not economically viable.

Then there's a problem with nuclear fuel. The sources are mostly countries you don't want to depend on.

You are of course right with your assessment that nuclear is green, safe and eco-friendly. That's a hard one to swallow for a lot of eco activists.

Long build times are often the result of constantly changing regulations. Also it’s interesting that build times in Japan are almost 2 times smaller than in US.

Nuclear doesn't have a great record in other countries either. I might have the wrong figures but Hinkley Points C is over 2 times over budget and likely to be 5+ years late.

The exemption being France and maybe China?

France did a programme of nuclear power stations rather than the 1 or 2 offs that seem to be the norm elsewhere and that seems to have worked pretty well.

I'd be surprised if HPC is competitive with solar + wind + BESS when it comes online but I could well be wrong

No, the exceptions are builds like HPC.

The average build time is currently 6.5 years. The median is lower at 5.8. The variations across both time and space of those average are neither large nor particularly systematic.

There have always been outliers, so if you focus on those you can "prove" anything you like.

Which for western construction creates a dataset weighted around ~1980. Not sure why that is relevant half a century later?

Instead taking the average of all modern western construction and we get close to 15 years.

With the recent insanely subsidies european projects being proposed even the initial timeline calls for a ~10 years build time. Assuming everything goes to plan.
