Yeah, the breeder reactors in the first generation were terrible and not good for much other than making A-bomb material.<p>That doesn&#x27;t really have anything to do with the dozens of nuke plants that were canceled in the 70s, at the height of the Cold War, and the virtual (and in some countries, legal) moratorium on new construction that was pushed by anti-nuclear activists.  Well-intentioned people dedicated to saving the world made things worse us and held back technological progress at the same time.
