Up until 2007, Kodak operated a small nuclear reactor that contained 3.5 pounds of weapons-grade highly enriched uranium.

The Democrat and Chronicle learned of the facility when an employee happened to mention it to a reporter a few months ago.

The recent silence was by design. Detailed information about nuclear power plants and other entities with radioactive material has been restricted since the 2001 terrorist attacks.

Nuclear non-proliferation experts express surprise that an industrial manufacturer like Eastman Kodak had had weapons-grade uranium, especially in a post-9/11 world.

"I've never heard of it at Kodak," said Miles Pomper, senior research associate at the Center for Nonproliferation Studies in Washington. "It's such an odd situation because private companies just don't have this material."
