If any of those plants go up, the entire region will go with it. So it really doesn't make much difference if you live on top of it or if you're 50 miles away.

That said, safety mechanisims on US reactors are TOTALLY different than those on Soviet ones. The Soviets cut a lot of corners because they thought "hey, we've never had an accident - we don't need this." Chernobyl went up because they were doing a dangerous test - trying to get power out of a reactor that was being shut down, and in the process turned off all of the automatic safety features.
