Seventy-five years ago, the sweeping landscape of the Idaho desert over the Snake River Aquifer was a land of sagebrush, brown grass and lava rock. Today, the desert site facilities of Idaho National Laboratory are still home to sagebrush, brown grass and lava rock but also to of some of the world鈥檚 most cutting-edge nuclear fuel research and reactor prototype development.

Discerning whether a nuclear reactor is being used to also create material for nuclear weapons is difficult, but capturing and analyzing antimatter particles has shown promise for monitoring what specific nuclear reactor operations are occurring, even from hundreds of miles away. Researchers have developed a detector that exploits Cherenkov radiation, sensing antineutrinos and characterizing their energy profiles from miles away as a way of monitoring activity at nuclear reactors. They proposed to assemble their device in northeast England and detect antineutrinos from reactors from all over the U.K. as well as in northern France.
