The AP1000® pressurized water reactor works on the simple concept that, in the event of a design-basis accident (such as a coolant pipe break), the plant is designed to achieve and maintain safe shutdown condition without any operator action and without the need for ac power or pumps. Instead of relying on active components such as diesel generators and pumps, the AP1000 relies on the natural forces of gravity, natural circulation and compressed gases to keep the core and containment from overheating.
This is the plant that will be built in Georgia.

That is good, but the greenies would rather stall a reactor like this replacing current reactors. They would rather have us rely on old unsafe designs because it fits their anti-nuclear agenda.
