[QUOTE] I'm not going to go and try to find the exact figures so I'm only going by what I hear at safety briefings when I'm working at nuclear power stations and that'd give a figure of 'some'. It depends on what you classify as potentially dangerous and how close to it happening you want to be before you start worrying about it. I don't think you should leave it until alarms are sounding before you start to consider something to be dangerous.[/QUOTE] NIMBY situation and I wouldn't want to live next to one, or a coal station or a wind farm. As someone else pointed out, the worse industrial disaster (yeah - OK, after British Leyland - I did like that line) was Bopal. Get a space elevator going and eject the waste away from Earth and I'd be happy. Cold fusion and go for it. But even without either of those technologies, I think we are seriouosly going to need to go nuclear even if my heart ain't really in it.
