The residents of Prypiat and half of central and eastern Europe would like to disagree.
3. Meltdowns never happen now as long as correct measures are made.
Well, system failure compounded with human operator error gets you at worst Chernobyl, at best Three Mile Island. And in an emergency, human error is very easy to worm its way in. Also, since most of these things are built and staffed by people well trained and fully aware of what'll happen if they screw up, statistically, the likelihood of catastrophic failure per operating hour is negligible, especially because we've seen what happens when one of these things blows up. Which is why protests against building nuclear power plants are silly.
But on the other hand, if one will go off, it'll leave a mark.
Hell, even assuming everything goes as intended, you're still either stuck importing the fuel, or having all sorts of worried people nosing around in your strategic affairs if you start enriching nuclear fuel on your own.
As for costs, it is, indeed, the initial investment that's the primary deterrent. Over here, with what we've been giving the Russian fuel companies in profit for heating alone ever since the USSR collapsed we could've had that reactor built six times over.
My point is, as PanH so well explained, that it's naive to lob nuclear power (or most any one project) as a panacea for energy problems.
I didn't go to jail. Or prison. And I actually got a phone number from a woman. So. That was surprising, to say the least.
Happy to hear that.
