Probably should be avoided on the Ring of Fire, as the Japan situation has shown that Earthquakes cause problems. In east America, Europe and Africa it's a good idea though.
Well, the reactor problem is just one of many problems caused by the earthquake, which, as I said, am optimistic that it can be contained. If it is as bad as TMI, then it can definitely be resolved without major consequences. They can definitely build more earthquake-resistant reactors but honestly, how can anyone see a 9.0 earthquake coming?
