This is a very interesting article regarding the safety of nuclear power.
There is a fear of nuclear power that is based on emotional concerns rather than fact. According to this study, gathering power from nuclear sources would be dramatically less dangerous, even in the event of a catastrophe such as Japan, than energy from coal or natural gas sources.
Not only that, but nuclear energy pollutes the environment much less than carbon-based sources. Many European countries have tried this and it has worked fantastically. In the 50+ year history of nuclear research, there have been three major accidents. While major catastrophes garner media attention, there are daily deaths that go unreported with the mining and transport of other types of energy.
In the United States, one of the best things we could do is continue to develop our resources with nuclear energy. We should not solely rely on nuclear energy, but it would be a giant improvement from our largely coal dominated energy system.
