The U.S. War Department borrowed 14,000 tons of government silver in its
drive to make the world’s first atomic bomb. That silver was shaped into
coils and busbars, current-conducting strips, to operate a giant mass
spectroscopy plant in eastern Tennessee. That plant processed the weapons-
grade uranium used in the bomb dropped over Hiroshima, Japan, in August 1945.
