if you want a comparison, Iran has the first - everyone is twitching about them enriching it to the second.
Everyone seems to forget the russians have more HEU reactors than everyone else combine. So as users of HEU we US, UK, Russia / Soviet Union, its believed that india currently does and france has previous. In 2013 russia had 56 HEU plants
I do believe IAEA are right to be concerned about proliferation of HEU around the world
