Of course we could attempt to shorten that, but that would probably mean compromising on safety.
I think it's less that it would mean compromising on safety and more that it would mean compromising on the appearance of safety because we'd have to stop letting the courts delay construction while they indulge everybody who tries to sue to stop it with meritless claims.
Also -- and I say this as a Georgia Power ratepayer on the hook for the vast cost overruns for Plant Vogtle 3 and 4 -- we would need to import foreign labor or something because here in the US we are demonstrably too incompetent and corrupt to do it properly ourselves.
