Ah, perhaps my source was off. Thanks for the additional data.

But looking at it another way, nuclear is less than twice coal. Estimating the cost of that georgia plant would put it at $16-17B, so those overruns would be atypical.

But my main point on cost is that government investment has been lacking in nuclear compared to renewables: https://www.forbes.com/sites/robertbryce/2021/12/27/why-is-solar-energy-getting-250-times-more-in-federal-tax-credits-than-nuclear/?sh=4a783c3221cf

Without investment, it's going to stay just as expensive. And the main regulating body not having a mandate to develop the technology has just been holding us back.
