It built and operated the B Reactor, the first full-scale plutonium production reactor. Plutonium manufactured at the HEW was used in the atomic bomb detonated in the Trinity test in July 1945, and in the Fat Man bomb used in the atomic bombing of Nagasaki in August 1945. The plant continued producing plutonium for nuclear weapons until 1971. The HEW was commanded by Colonel Franklin T. Matthias until January 1946, and then by Colonel Frederick J. Clarke.
