Atomic Energy Unnecessary, Uneconomic, Uninsurable, Unevacuable and Unsafe.

I'm currently reading Normal Accidents, by Charles Perrow. You might think that accidents involving several independent things going wrong in combination would be so unlikely as to be negligible. That's if you expect nuclear power plants to be maintained at a very high standard. The book explains that it is usual for various valves and devices and meters to be broken. To have just one thing wrong is normal; for several to combine is not rare.
