You've heard of Chernobyl, and you've even heard of Fukushima. But the next biggest nuclear disaster probably won't ring any bells for you, and that's because it was largely kept secret. The Kyshtym disaster of 1957 was the third largest nuclear accident, but not even those affected knew it had happened. Heck, it didn't even happen in Kyshtym—the name was something of a cover-up. The disaster occurred in the secret, then-Soviet region called Chelyabinsk (it was renamed Ozyorsk in the early 1990s). According to the Soviets, the secret site of the accident didn't even exist.
