Inscription. Since 1949, more nuclear reactors – over 50 of them – have been built on this plain than anywhere else in the world.

This 900-square-mile Idaho National Laboratory is the birthplace of the Nuclear Navy. Commercial power reactor prototypes, including reactors that breed more fuel than they consume were developed here.
