According to How Big Things Get Done, at least 30B worth. Nuclear plants have some of the worst cost and time overruns for large projects, wind and solar some of the lowest (beaten only by roads).
And his theory as to why this happens, is that wind, solar, and roads are self-similar. Building the first 10% directly informs you on how to build the next 10%. Everything you learn along the way can be rolled back into the project in a feedback loop.
What you learn shingling a roof or building a nuclear reactor doesn't help this project all that much. It helps the next. And how many nuclear reactors does one worker build in their lifetime? 2? 4? That's not a lot of opportunity for process improvement.
