gravity Sometimes the best ideas are just that simple. When we designed the AP1000 nuclear reactor, we asked ourselves which would be more reliable, multiple arrays of electro-mechanical systems or gravity. To us, the answer is obvious, which is why the AP1000 nuclear power plant makes use of the stable forces of nature to keep the nuclear reactor safe aſt er any unforeseen event. No need for electrical power. No need for cooling water (that is already inside the robust containment building). No need for an operator to touch a single button for a full 72 hours.
