  1. The biggest issue for Chernobyl was that the EZ-5 button (called SCRAM in Western countries) was designed to work correctly in designed operation states. The most important was that the core must have minimum of 30 control rods inserted at all times. And of course, the team operating the reactor before the accident had fully pulled all but 6–8 rods from the reactor. This would have caused runaway situation even earlier but thanks to strong xenon poisoning, the reactor was able to stay in low power state until practically all xenon was burned away.
