Logan Emlet was the Director of the Operations Division at the X-10 reactor in Oak Ridge, TN during the Manhattan Project.
After the war, Emlet continued to work at Oak Ridge on the Radioisotope Production Program. In 1948, Emlet, W. Ragan, C.G. Goss, and D.D. Walker sought to demonstrate the production of electricity from a nuclear reactor. The team experimented by transforming a toy steam engine into a generator that altered steam produced by Oak Ridge’s Graphite Reactor to power a lightbulb.
Between 1952 and 1954, Emlet served as the Y-12 Plant Manager.
