What takes decades is the bureaucracy, it can take as little as 3-5 years without the constant attempts to slow it down. We know the plant can then run for the next 50+ years. It needs to be part of the solution because power demand is constantly growing and we need to phase out other sources. Solar and wind aren’t enough and can’t get built fast enough alone.

The alternative option is to just force China, India, and every African nation to stop developing. That would reduce power needs enough that solar and wind would be sufficient.
