Did it work great in France? The financing was so opaque it cannot be audited.

What we do know is that France can no longer do what they once maybe did. Their recent attempts to build nuclear plants have been disastrous. They've also given up on fast reactors, which is a clear tell they do not expect the world to go nuclear anytime soon (if the world did, it would quickly need breeders).

The "environmentalists did it" argument is not a good one. It falls apart when examined closely. If they were so powerful as to suppress nuclear worldwide, why can't they (for example) stop oil pipelines? Or coal combustion? The argument has all the signs of something cooked up to save a tenuous position, not because the evidence actually supports it.
