It took 5 years from construction start to grid connection for Oskarshamn R3, at the time the reactor with the world’s highest rated output. Since it began operating it has produced 350TWh.

That nuclear power must take forever is a myth and is only due to dysfunctional politics.

That “you get a permit in the winter and it’s done by summer” is a totally bogus claim. Perhaps for some tiny installation compared to a power plant with 1.5GW output.
