Description of the clip from the website: "At an atomic laboratory in Chalk River, Ont., CBC reporter J. Frank Willis is trying to grasp the intricacies of nuclear power. How does a lump of uranium become the destructive source of power in the atomic bomb? The key is neutrons. When uranium is blasted with a stream of neutrons, it becomes a new element: plutonium. With enough plutonium, nuclear fission occurs, setting off a chain reaction as billions upon billions of atoms explode."
