The word "camera" comes to mind when you think of the company Kodak, so you're probably just as surprised as we were when we found out that Kodak kept a nuclear reactor a secret for more than 30 years. The reactor was kept in an underground basement in Rochester, New York.
Kodak bought the reactor in 1974, which was known as a Californium Neutron Flex multiplier, which was filled with 3.5 pounds of uranium plates, the type of material used to make nuclear weapons.
The device was kept in a bunker with 2-foot thick walls and was always under tight security. One two of these devices were ever built!
Kodak claims that the device was completely safe, and that they used it for decades to conduct research, and check materials for impurities!
The local police and fire departments were completely unaware of the nuclear reactor's existence!
