Contractor selection During World War II, the S-1 Section of the federal Office of Scientific Research and Development (OSRD) sponsored a research project on plutonium. Research was conducted by scientists at the University of Chicago Metallurgical Laboratory. At the time, plutonium was a rare element that had only recently been synthesized in laboratories. It was theorized that plutonium was fissile and could be used in an atomic bomb. The United States government was concerned that Nazi Germany was developing a nuclear weapons program. The Metallurgical Laboratory physicists worked on designing nuclear reactors ("piles") that could irradiate uranium and transmute it into plutonium. Meanwhile, chemists investigated ways to separate plutonium from uranium.
