It turns out Kodak had a secret underground nuclear reactor in its headquarters that contained 3.5 pounds of highly enriched uranium. The existence of this reactor was kept secret from state and local authorities for years and the reactor was finally dismantled in 2006.
Kodak used it to check chemicals and other materials for impurities, Filo said. It also was used for tests related to neutron radiography, an imaging technique.
The device was not much larger than a refrigerator and, in the one available photo, looked vaguely like Robby the Robot from a 1950s science fiction movie. To house it, Kodak dug a cavity below the basement level of Building 82, part of the company’s research complex along Lake Avenue.
