> If more nuclear takes 20+ years to build while we can get wind farms online next month, is it really faster? Building (roughly) plants 1 through 3 will be the hardest, take the longest, and cost the most, but after that—assuming you use the same design throughout—you can build quite quickly. Japan averaged ~5 years between beginning of construction and commercial operations: * https://en.wikipedia.org/wiki/List_of_commercial_nuclear_reactors#Japan https://en.wikipedia.org/wiki/List_of_commercial_nuclear_rea...

It helps if you don't start and stop projects/plants: many cost over-runs are because of wishy-washy decision making. > When’s the last time anyone built a nuclear plant in 4 years? 2004 to 2009 is five, Tomari 3 in Japan: * https://en.wikipedia.org/wiki/Tomari_Nuclear_Power_Plant https://en.wikipedia.org/wiki/Tomari_Nuclear_Power_Plant
