I know why people are scared: Three Mile Island, Chernobyl, "The China Syndrome", however, the tech of nuclear power has improved tremendously. Safer and cleaner. The only way to keep up with power demand, and cut fossil fuel usage. Otherwise we stop using fossil fuels, and go back to living in caves. Only this time, we can't even have camp fires for fear of emitting too much CO2. Just sitting around in the dark, fighting over whatever rotted fruit fell off the nearest fruit tree that day.
