Passive nuclear safety

Passive nuclear safety is a type of safety measure that helps protect people from the danger of nuclear power plants. It works by designing the nuclear power plant so that any problems that may happen are taken care of without anyone having to do anything. For example, if the reactor gets too hot, the system will automatically shut down to keep it from getting too hot. The safety system is always working to make sure that the power plant is safe and running correctly.
