So there was talk about deaths per energy unit produced for different energy production methods. Here are some numbers:

As you can see nuclear power is at the very bottom.
If I should try to say any reason to be against it, it would be:
1) Possible proliferation of nuclear weapon technology to states that really should not have it, for example Iran.
2) Long-term storage problems. Humans seem to forget the locations of thing very rapidly in history. One example is sunken ships, I am sure there are others. (Perhaps this is alleviated by modern technology.) Also, there is a risk of leakage. It's hard to realistically test containers that are supposed to hold for 100,000 years. A lot of things can happen geologically during this time.
I would also like to say that the Italian cold fusion experiment mentioned earlier is almost certain to be a fraud, so don't get your hopes up. All warning lights are blinking: no external tests allowed, no patent, no peer reviewed articles, no funding, etc.
