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 am against nuclear energy because my government is deeply corrupted and give contracts to their friends. They also appoint unqualified people to the highest positions to award them big salaries and the results are catastrophic tragedies with tens of casualties each time. I don’t trust them to operate the railroads, why would I trust them to operate a nuclear facility?

I was involved in the nuclear industry in the 90's.

Why impose externalities on others when solar and wind are so cheap and less risky? It seems like proponents fall for technological aspirationalism without considering pragmatic consequences and risks of shoveling enormous sums of money for unnecessary risks and inefficient allocations of capital because it's seems just barely unobtainable or blocked by "them" when it's simply economically unviable.

And it's selective technological aspirationalism. Why is unbounded optimism appropriate for nuclear but not for renewables? The engineering principle of KISS says renewables should be much more improvable, as indeed the data indicates they are.

It's the other way around.

Nuclear works now. We just have to build it.

Intermittent renewables supplying an industrial society does not. And there is no way to get from here to there except a lot of handwaving and "magic happens here".

When you have to build Nuclear Reactors then this is not now. The avg. building time of Nuclear Reactors is 9-12 Years.

6.5 years.

I am counting delays that are always occuring. There is only two reactor blocks that I know that didn't have delays in recent years.

These are build times for just single Reactor Blocks, in 2020 to 2022. https://www.worldnuclearreport.org/IMG/pdf/wnisr2023-v5.pdf#...

Real examples in the last years: Olkiluoto 3 - 17 Years SHIDAO BAY-1 - 9 Years Flammanvill-3 - 17 Years VOGTLE-4 - 11 Years FANGCHENGGANG-4 - 8 Years RAJASTHAN-7 - 14 Years

No you are cherry picking specific examples that fit your incorrect claim. 6.5 years is the current average.
