Not so good news for Chenobyl however. The Russians built sh***y unsafe reactors which were operated by drunken komimisars.
A large factor in the severity of that meltdown was a known and acknowledged design flaw. It was designed to produce electricity as well as rapidly produce weapons grade plutonium. The unfortunate side effect is a positive coefficient for reactivity, which basically means as the temperature goes up, the reactivity rate goes up, which causes the temperature to go up, and on and on until supercriticality (although this can happen in less than a second). Part of the problem was the pressure to keep up with the US in the Cold War arms race mentality of mutually assured destruction.
The US has so many restrictions, regulations, and minimum requirements for safeguards, backup systems, and interlocks that the possibility of a reactor going supercritical is almost zero. Even if it does go supercritical, the NRC requirements make it so that automatic containment systems kick in. These requirements make it expensive and time consuming to build a nuclear reactor and are also the reason that nuclear power does not provide electricity "too cheap to meter."
