Rejection of nuclear power wasn't down to Greens or CND types. They don't wield that kind of political power, especially in the major nuclear states where most reactor development was/is happening (USA, Russia, China, UK, France, Japan). Politicians stopped building nuclear power plants because it's expensive (zomg DEBT) and locally unpopular and didn't fit in with the ideology of either centre right or 3rd way centre left parties of the last 30 years in most western countries (i.e. it's centralised, heavily regulated and heavily state subsidised).

It's tragic that development stalled, but blaming some of the people who are most sympathetic to the nuclear power argument in the modern debate isn't really productive.
