What reactor is operational in 6 to 8 years? Can you point to a recent project that went online in that timeframe? Would be interesting how much nuclear capacity cost in comparison to reweables like solar wind or hydro and long range distribution nets or batteries.
This might serve as source for those 6-8 years. It seems more like a global/historical number as the author also notes that there isn't much recent data for the US or Europe.
Terrapower just broke ground on a new reactor in the US, it's expected to be completed in approx 6 years. Even with significant delays it would be under 8 years and almost certainly under a decade.
While not touching on cost, this link shows how much more power generation you can get with nuclear compared to other sources of low carbon energy over a decade of deployment. If you need to generate a lot of energy relatively quickly and don't have amazing hydro options, nuclear appears the most scalable.
