This is nuts. I wonder what the effect of spending $1T on nuclear would be in comparison. I bet it's enough money to get to practical nuclear fusion in a decade, which would largely obviate the need in most other energy generation methods.
Looks like a single fission plant costs around 6 to 9 billion and construction costs tend to go up. There's not a lot of room for iteration and learning from experience; you have to get it right the first time.
Compare that with a competitive industry that's manufacturing in bulk and improving every year. Where do the lines cross?
