The "specialists" said a big Nuclear Meltdown is only one in 100000 years. I'm 43 years old and in my life there was 3 Mile Island, Chernobyl, and now Japan.
Under any definition of the word "big" you want to use, Three Mile Island didn't have a "big" meltdown. Partial yes, (just like in Japan), but under no circumstances was it "big". Chernobyl was big, yes, but it was caused by idiots. Clearly it should be illegal for idiots to run nuclear power plants (or any power plants for that matter), but to suggest we shouldn't continue to utilize nuclear power as one of our many methods of getting electricity based on these three incidents is just silly.
