Kodak officials now admit that they never made any public announcement about it. In fact, nobody in the city—officials, police or firemen—or in the state of New York or anywhere else knew about it until it was recently leaked by an ex-employee. Its existence and whereabouts were purposely kept vague and only a few engineers and Federal employees really knew about the project.
It’s extremely strange that Kodak managed to get something like this. According to Miles Pomper, from the Center for Nonproliferation Studies in Washington. it’s “such an odd situation because private companies just don’t have this material.”
Kodak’s purpose for the reactor wasn’t sinister: they used it to check materials for impurities as well as neutron radiography testing.
