I don't buy this at all. First of all, even assuming these regulations were required at one time, it doesn't suppose that they're still needed today to keep nuclear reasonably safe--we could ostensibly lift much of that unnecessary regulation now that things are safe and allow nuclear to compete fairly.

Secondly, the whole point of anti-nuclear FUD is/was to make nuclear "politically unrealistic", so it doesn't make sense to argue that "political realism"--not FUD--is responsible for the high levels of regulation.

Thirdly, lots of countries (China, South Korea, etc) have had nuclear programs with much lower levels of regulation and far better economics, which goes to show that, absent FUD, nuclear power can be safe enough to be "politically realistic".
