Nuclear reactors constructed for “peaceful” purposes to generate electricity nevertheless constitute a danger in that they generate fissionable isotopes of plutonium, neptunium and americium and, are not under strict international control. Since 1945, more than 3,000 metric tons (3,000,000 kilograms) of highly enrichedÃÂ ...

The precursor to plutonium- 238 is neptunium-237, a radioactive by-product of nuclear power plants. Oak Ridge gets its neptunium trucked in from Idaho National Laboratory in a powdery form called oxide. When it arrives, it's deposited via a dumbwaiter-like system in a shielded room called a hot cell.
