I suspect that building and operating a nuclear plant is more complex than coal, however this table indicates there are currently 2445 operating coal plants currently, and approx 500 in pre-construction or construction. So is it really that hard to fathom operating 5000 nuclear plants? Especially if our existence might depend on it? I also don't think people are recommending replacing EVERY source of energy with nuclear... just the dirty ones.
